Hi! I saw that many (myself initially) fail to understand the discussions of various topics of modding on this and other forums because of certain terms that are now characteristic of speech in any argument.
-Android operating system for mobile devices based on Linux kernel. Android is an open source project developed by the Open Handset Alliance (OHA). Google was the first company to work on Android and HTC has designed and implemented the first Android phone.
-ADB (Android Debugging Bridge): application via command line (command prompt, DOS), is used to flash rom, make changes to the system, backup, install applications (using the command: adb push nomeapp.apk / system / app /), copy files from your device to PC (via the command: adb pull / path / inside / of / Android / filename nome_file_destinazione) and more. ADB is a tool included in the SDK of Android that allows you to manage your phone simply by connecting it via USB. For programmers, ADB is also used to execute commands on a virtual machine Android. detailed instructions.
- Apk (short for Android Package): is the file format used to install the Android software (it works similar, more or less, that is for Windows. Exe). Renaming the extension of this file. Zip you can open it with any operator of compressed files.

-G. E. often written or GE (Google Experience): There are those phones that have the OS (see ROM for a definition) fully developed by Google without any addition or customization by the manufacturer that sells the device (for example the number of mobile Nexus is entirely GE). This designation often means that these phones are the first to receive updates of new versions of Android, because there being no additional software, as well as those developed by Google, the release is much quicker.
Another (more common) is that With Google.
Are those phones that despite having some customization software by the manufacturer, are fully compatible with the Google software and services with Android.

- Launcher: It 's the software that handles the desktop (icons, widgets, wallpapers etc..) Android operating system. In essence, is what appears when you access the phone after the unlock screen, called Lock Screen (see below) if it is enabled.
Android allows for excellent customization Lacuncher. Although all versions of Android will already have a default, it is possible (when this option is not blocked by the manufacturer) install as many as you want from those in the Market. Launcher The best known of those owners are not ADW Launcher, Launcher Pro, Helix Lancher.
Most producers customize more or less heavily, their phones (as long as they are not GE, see above), and modification of the launcher is usually the most common personalization. Motorola for example sviluppaMotoBlur (non-removable, and includes an additional set of changes including the Launcher), the HTC the Sense (removable; this also includes modifications to the deepest only launcher which also include the framework), Samsung TouchWiz the (removable) etc..

-ROOT (I take verbatim from androidpedia): What is root? In Unix-like operating systems is denoted by the root user with the highest privileges, ie, system administrator, also known as super user or superuser. (Cited in Wikipedia). Android being a linux system, then the user is root, which allows you to have total control of the phone. What a privilege we have to have root permissions? We have TOTAL control of the telephone. rootare the procedure for your device varies from terminal to terminal, consult the relevant sections to find out how to make your root device ..

May be predominantly via USB connectivity, bluetooth or wifi phone.
-Tablet is a tablet device that differs from a smartphone to the screen size (usually greater than the 5 "and for its strong propensity to navigation and document management. It usually does not incorporate a module for telephone calls (one exception is the Galaxy Tab), but often have a data connection via 3G or 4G as well as the WIFI.

Sorry but:
-Bootloader (FASTBOOT): phone mode (while connected to USB mode with usb debug enabled)
Is wrong. Bootloader and fastboot are not the same. Also USB debugging mode is an android thing, when you are not booted into android (eg into fastboot or bootloader) then usb debugging mode is not used

I wanted to create a thread so as to report any unique findings from the internet realm regarding the Nvidia Tegra Note OEM Tablet.
Please post your own discoveries and updates!!!
Bootloader Partition Images
WARNING ONLY ADJUST PARTITIONS IF YOUR DEVICE HAS A WORKING BOOTLOADER WITH FASTBOOT
(Some early devices have a limited bootloader with no menu and no fastboot mode. If this is so, do not modify your partitions unless certain of your actions. A bootloader is a special device starting partition that later starts the extended boot partition. The bootloader should give fastboot access allowing you to re-partition or correct mistakes.)
Buttons: Power-Button + Top-Volume. Release after a few second..
= Bootloader menu should show, allowing fastboot 'on' switch
= or Blank Screen Bootloader possibly with fastboot (read above warning)
To partition your device you do need it unlocked it. The command below should do this. You need a fastboot commandline service which is usually supplied from the bootloader level. The computer used to control the changes also needs its own ADB and FASTBOOT protocol utilities.
After the below command is issued your device will reboot and user data wiped! You device should then be open for partition changes.
Code:
fastboot oem unlock

UART Ability?
After an inspection I can't see any points to which one could easily tap into an 'exposed console' with a USB UART setup. This could indicate there is no allocation to access a terminal from a tapped in serial port or pins off the minute and well protected chipsets. Obviously those that want to software repair these tablets have access to NvFlash/APX mode, in dire situations.

Xposed Installer
Xposed is a framework for modules that can change the behavior of the system and apps without touching any APKs. That's great because it means that modules can work for different versions and even ROMs without any changes (as long as the original code was not changed too much). It's also easy to undo. As all changes are done in the memory, you just need to deactivate the module and reboot to get your original system back. There are many other advantages, but here is just one more: Multiple modules can do changes to the same part of the system or app. With modified APKs, you to decide for one. No way to combine them, unless the author builds multiple APKs with different combinations.

Installing Google Play on Nvidia Tegra Note.
0. Get a powerful Recovery partition image on your Tablet.
1. Obtain a Google Apps pack, usually termed GAPPS suited to your Android version.
2. Use Recovery's install zip mode to install.
Lollipop Fresh Installation + Tweaking
(for those with basic knowledge of Android manipulation)
* Make sure your tablet is OEM unlocked. Then flash a sophisticated recover image version like TWRP. This will allow root-mode enabling via a patch.
To obtain fastboot-mode, you need another computer as the debugging/command platform via USB. Holding the POWER-BUTTON and UP-VOLUME on the boot and shortly after releasing the POWER-BUTTON and later the other, will bring up a bootloader menu that can deploy fastboot protocol/mode or get to recovery-mode. This is where you can flash, oem unlock, and erase partitions, with the data coming from your command-platform. You can't format nor erase partitions till you oem-unlock the device, noting an oem unlock clears your device's user data.
Your command-platform (controlling computer used to upgrade the Tegra Note) also needs its own version of ADB (Android Debugging Bridge) and FASTBOOT protocols so as to be able to talk and understand the conversation over the USB.
RootJunky also has versions of TWRP and other recovery image versions.
* Put the tablet into fastboot-mode and flash RootJunky's shared Lollipop restore image instead of the upgrade over the air (OTA). Good idea to erase particular partition before flashing.
* Boot to the recovery stage. Install latest SuperSu.zip using sideloader or having it already on a SD. This will enable root mode.
https://download.chainfire.eu/740/SuperSU (Get Beta if available.)
* Start system. Remove Apps from system partition unneeded, or that can be moved or installed to user directory instead. This frees up vital space. Example Lollipop only leaves a few megabytes left in the system partition after installation. Consider using Link2SD. Example get Google+, Google Play, Google Magazine, etc into the user partition and any other big App off your system partition. The system partition should only have important apps needed to be retained if a factory wipe is enacted.
* Then go through all your system settings make sure you tweak them to suit both power saving and your own desires.
* Use a start-up tool like ES Task Manager to remove apps starting that don't need to be running from system boot.
* Install all Google Apps wanted. This can help to configure the system how it's meant to be.
* You could install Google Now into the system partition and remove the Launcher3 App.
* The system should now run smooth and use little battery.

I had the same problem when I was trying to use Helium to restore some apps. Windows 7 64 bit was able to install two of the three component 'parts' of the tablet but not the final driver. After the device installer had finished in opened Control Panel on the PC and then the Device Manager. The Note should be listed in Device Manager with a yellow exclamation mark. Right click on it and select 'update driver'. In the next window choose to install the driver yourself, then opt to choose from a list of drivers manually. Next choose the entry called 'Android Phone', then select 'composite ADB device' from the list on the right. I'm saying this from memory I may have missed a step so tread carefully. I already had the desktop Helium app installed on my PC which installation ADB drivers (they'll appear under Clockwork Mod in the driver list I mentioned). I'm away from my PC for now so it'll be a while before I can refine these instructions.
These are just basic observations, but I've playing around with the Note connected to a TV and USB hub etc

Did you already have the drivers downloaded and installed to your machine, or did it use its own drivers?
that'd be great if folks no longer need to get the drivers manually set up and override the crying about mismatches.
My Tegra Note Homecare Fly One does not connect on my PC ..
Does anyone have the drivers?
thank you
I made a discovery.....Battery drain issue.....battery drains really fast even when on power save settings with prism and running on 1 core..... Even when im not even using it like the memory is clean and cache is clear and everything.......After 100% charge it barely lasts me 6 hours of a day at college when im using it on and off....Like word processing and taking a couple of photos thats it.....
So after a few days since I got it the battery started getting better and better......So what was 6 hours of on and off usage of my tablet is not almost 24 hours of the same kinds of usage with still 45% ish of battery remainig!!!!! So I guess the way we charge our devices makes a difference as well....Batery doctor has a feature that charges the device in a specific way like as fast as possible to 80% then slows current down to prelong battery life. I want to see how long my battery will last and will upload screenshots while im doing so.....Right now it is 10:26 pm and battery is at 43% with 22 hours and 2 mins on battery.

If you're upgrading from a stock ROM (any variety), please click the "show content" button and read the instructions very carefully - they're long but your tablet's continued good health may depend on it!
STEP 1: Install TWRP or Philz Touch Recovery
Users outside the US must use the DoPa versions of these recoveries to install the ROM - neither the stock recovery nor other versions of CWM or Philz will work. Users in the US should use them just to avoid problems.
Stock Recovery
If you still have the stock recovery program you'll have to use the 'fastboot' program to install TWRP or Philz. On Windows, this requires installation of the 'ADB' USB drivers while in fastboot mode (see below). A package containing the drivers, fastboot, adb and other files can be found in the 2nd posting on the DoPa Stock ROM thread. Note: there are several batch files (*.bat) in the package - do NOT run them.
put fastboot.exe in a convenient directory, then unzip the recovery zip and put the .img file (twrp.img or philz.img) in the same directory (you won't need the other files)
unplug any USB cable, then press and hold Power+VolumeUp; the word "fastboot" should appear on the screen (nothing further will appear)
plug the USB cable from your PC into the tablet, then install the driver (open Device Manager, right click on "Other Devices->Fastboot", then select "Update Driver Software")
after installing the driver, open a command prompt ("DOS window") and change to the directory containing the files
enter, as appropriate, fastboot flash recovery twrp.img or fastboot flash recovery philz.img
when done, force the tablet off, remove the USB cable, then reboot into recovery: Power+VolumeDown - you should see the word "recovery", then either the TWRP or Philz menu
CWM
If you have CWM installed, copy your choice of recovery zip to an SD card, insert it in the tablet, then:
remove any USB cable, then boot into recovery: Power+VolumeDown
select "Install Zip", then "Choose zip from /storage/sdcard1"
select the file, then OK the selection
when done, back out to the main menu, select "Advanced options", then "Reboot recovery"
after the initial "recovery" screen, you should see the TWRP or Philz menu
Regardless of how you install your chosen recovery, the result should be the same. If it boots OK, compatibility is assured
STEP 2: Backup
I can't emphasize this enough: you must make a backup of your existing ROM. If something goes wrong, there's no way to get your device working again other than to restore it using the backup you've made. There's also another reason to do a backup: before installing the new ROM, you will have to reformat your /data partition. This will wipe out your apps, your settings, and most importantly, all the music/photos/etc stored on your "internal SDcard". These last items can be restored if you follow the instructions below:
You must do your backup onto a real SD card that you can remove because your "internal SDcard" will be erased in the next step. In fact, it wouldn't be a bad idea to do two backups (preferably to different cards) just in case one is faulty.
using Philz, select "Backup and Restore", then "Backup to /storage/sdcard1" -if there's enough space on the card, the backup will start without any further prompt;
using TWRP, select "Backup", then tap "Storage" (halfway down the screen) and ensure that "sdcard" is selected; on the previous screen, swipe the slider to start the backup;
it could take anywhere from 3 to 15+ minutes depending on the amount of data and the speed of your card
if needed, you can enable compression to create a smaller backup: for TWRP, you can check "Enable compression" on its main backup screen; for Philz, select "Misc Nandroid Settings -> Default Backup Format -> tar + gzip", then on the previous menu, tap on "Compression" to set the appropriate level
STEP 3: Install the DoPa5 ROM
Before you begin, you may want to download a Google Apps ("Gapps") package that you can install after the ROM. See the TK Gapps thread for details. I recommend the "Nano Modular" package which gives you the basics - you can always upgrade later. Put your Gapps package along with the ROM zip on an SD card and insert it into the tablet - you can use the same card you're using for your backups.
using TWRP, select "Wipe", then "Format data"; on the next screen type "yes" to confirm you want to proceed;
using Philz, select "Wipe and Format Options", then "Custom Format Options"; next select "format /data and /data/media (/sdcard)" (the 8th item), then OK your choice;
return to the main menu
using TWRP, select "Install"; at the top it should show "Storage: sdcard" - if not, tap there and change the setting
using Philz, select "Install Zip -> Choose zip from /storage/sdcard1"
select sero7pro-aosp511-dopa5-v1.3.zip, then OK your choice - the install process should take about 40-60 seconds
next, install your Gapps package
return to the main menu, select "Reboot" then "System" if using TWRP, or "Reboot System Now" for Philz, then hold your breath for the next 3-4 minutes
the Hisense screen should be up for 30 seconds, followed by the DoPa boot animation for another 3 minutes
If the boot animation is still running after 5+ minutes, force the tablet off, then reboot. If that doesn't fix it, try formatting /data again. If it still doesn't work, restore your tablet from your backup ("Backup and Restore -> Restore from /storage/sdcard1"), then post a message here. If everything works out as hoped for, re-read the first posting in this thread for details on some of the features (and problems) of this ROM.
Upgrades
UK, AU, and DE users must use the DoPa versions of TWRP or Philz Touch to install the ROM because they are the only ones compatible with your tablet. US users can use any SELinux-enabled version of CWM, Philz, or TWRP.
from DoPa5 AOSP Lollipop ROMs - no need to wipe or format anything!
from DoPa AOSP Kitkat ROMs (v1.0-v2.7) - a clean install is recommended but not required
from pre-Kitkat (v4.4.x) or any CM-based ROMs - wipe your /data partition before installing to avoid unnecessary problems.
install sero7pro-aosp511-dopa5-v1.3.zip
- the installer will wipe (but NOT format) /cache and dalvik-cache for you
install your preferred Gapps package
- upgraders: this is required to prevent your downloaded Google apps from crashing
optionally, install the Nexus7 spoof (sero7pro-nexus7spoof-dopa5-v1.3.zip)
reboot (ignore any "fix root" prompt - it's incorrect)
f2fs / ext4 Migration
This DoPa ROM gives you the flexibility to format any of your built-in partitions using either the f2fs or ext4 file systems.
As part of your install - or at any time - you can switch formats without losing any data. Click "show content" for instructions.
If you haven't already installed TWRP or Philz Touch Recovery, please do so first.
TWRP
make a backup to your external SD card
select Wipe then Advanced Wipe
select the partition to reformat, then tap Repair or Change File System
on the next screen, tap Change File System, then F2FS (or EXT4 to restore the default file system)
swipe the slider below to start formatting
when done, use the Restore option on the main screen to restore the contents of the partitions you reformatted
Philz
make a nandroid backup to your external SD card
select Wipe and Format Options, then Custom Format Options
select toggle f2fs <-> ext4 migration
- be sure there's a confirmation message at the bottom of the screen
select each partition you want to convert or wipe, then select the format and OK your choice
Important: to convert your /data partition, you must select format /data and /data/media (/sdcard)!!!
use Custom Restore from /storage/sdcard1 to restore the contents of the partitions you reformatted
Changes since DoPa5 v1.2
Xposed and GravityBox - these staples of the DoPa KitKat ROMs are back and preinstalled to provide all the tweaks you want - and none of the ones you don't
ArchiDroid Optimizations - this version of Android was built using gcc 4.9 and is highly optimized thanks to settings provided by JustArchi. To help ensure stability, the kernel uses standard optimization levels but is better tuned to our Cortex A9 processor due to the use of linaro 4.9 (a version of gcc optimized for ARM processors).
No Odex-ing - odex-ing has been abandoned because Xposed recompiles all apps, making the .odex files redundant. There should now be enough space on the /system partition to install the TK-Gapps Micro package.
Adaptive Brightness - a longstanding bug that could cause the screen to go black has been fixed. Overall brightness levels have been adjusted to provide greater dynamic range in low lighting conditions.
Notes
Xposed - having the Xposed framework installed shouldn't cause any issues, but if you wish to remove it you can do so using the xposed-uninstaller available in the Xposed XDA thread. The Xposed Installer and GravityBox apps will remain but will be inactive - you can use a root-enabled filemanager to remove them if you wish.
Encryption - if you wish to encrypt your /data partition, you must first use Philz Recovery to format it. Using TWRP to format may cause the partition to become un-decrytable, resulting in the complete loss of all your data. This is NOT an issue if you don't plan to use encryption.
WiFi Display - end a WiFi Display session from your television, not the tablet; doing so from the tablet may cause it to lock up. Chromecast is reportedly not subject to this issue.
USB Audio - booting up with a USB audio device attached may result in a bootloop.
Gapps - due to limited space on the /system partition, the TK Gapps's "Mini Modular" and larger packages will not install. I suggest using the "Nano" package, then downloading those apps you really want from PlayStore.

Thx for all your hard work
on these tablet
Thx
ok, so I have a question or several as I remember them...
I noticed in Beta 4 that we were (or at least I was) suffering from the well documented play movies bug that was afflicting a number of 2013 Nexus 7 models.
Has this been fixed yet?
If not, is there a workaround?
If so, what is it?
I also noticed some performance and stability issues when using the performance tab along with apps like 3c Toolbox and System Tuner. Unfortunately, I did not see a way to use performance tab to overclock the gpu and leave the cpu clock stock so that I could tweak the system through the aforementioned apps.
Also, can the cpu be overclocked beyond 1.5 Ghz?
If so, is this already enabled, or is there some magic involved?
I really liked the beta 4 (beta r3) Rom and the way it looked, felt, and ran.
I found it to be better at managing free memory than kitkat in that I had at least 50% more free ram than Kitkat. I believe this contributed to some of the performance increase. But I had a hard time with the Google Play Movies bug. And some people were saying it was a general problem within the os's video subsystem.
Legend, keep up the great work
Excellent work! Looking forward to this!

I'm sorry I didn't know about this until you mentioned it. I'm too poor/cheap to buy stuff from Google Play Movies, so I'd never have learned about this on my own. Fortunately this was my day off, so I was able to spend the afternoon chasing down this bug. Here's the fix - install it from Recovery:
sero7pro-video-drm-fix-dopa5-v1.0.zip
I'll repackage the main ROM in the near future to include this fix, but first I want to investigate a few possible problems I noticed while getting this fixed.

Every time you display the Performance page, it will restore all parameters to the values you set previously. If 'Speed Control' is enabled, it will reset the CPU & GPU speeds, overriding values set by some other app. Your best bet is to turn it off. If neither of the apps you mention knows how to set the GPU speed, you can do so temporarily from a terminal or permanently from an init.d script like so:
Code:
echo -n 1250 > /sys/kernel/tegra_cap/core_cap_level # "1200" is 448mhz - "1250" is 520mhz
echo -n 1 > /sys/kernel/tegra_cap/core_cap_state

Nope, not without extending the kernel's DVFS table further, then recompiling. Someone had it running at 1700mhz, but I'd consider that ..umm.. ill-advised for a chip that's intended to run at 1200-1300mhz.
Loving the first build. Very silky smooth speed and pretty stable as well as far as Lollipop is concerned at this point. As far as themes are concerned I haven't had too many issues using them on the current CM12 nightly for the Sero 7 Pro despite the DPI difference. Can't wait to see where this goes from here. Thanks for all the hard work! :highfive:

Well, on nVidia's page it recommend a maximum of 1.6 GHz, so 1.7 is not too much of an overboard if Hisense had built these units well enough. However, even with 1.5 GHz the chips is already running uncomfortably hot so it would be wise to back off from any higher clock. I do however think that the GPU of this tablet is a lacking a bit of oomph (ironically), is it possible to raise the clocks of the GPU beyond 520MHz? (granted that there would be a possibility of artifacts )

Being under that magic number of 10 posts, I couldn't post this in that main thread, and when I tried to post in the q&a thread where "reply" sent me, the forums bot catcher tripped me up.
Thanks, that worked like a charm.

To my knowledge, they don't, or at least I haven't figured that part out yet. Haven't figured it out in trickster mod either. I'll try the code. I only remember seeing one init.d file, does it matter where in that file I add the code?

The Tegra3 is a family of SoCs with models designed for mobile, automotive, and embedded use. Ours is the low-power mobile version. Some variants do have higher maximum clock speeds but they use more power at every frequency step than ours.

Click to expand...

Possibly. The original overclock patch just upped the GPU speed to 520mhz without increasing the voltage any - and that seemed to work. When I rewrote the o/c code, I increased the voltage when running at 520mhz for what I considered solid reasons, Since it now has more power, I suspect I could up the speed somewhat without causing problems. However, even at a higher speed, it's still going to be an also-ran in today's market.

Having some other app set the CPU or GPU speeds isn't going to make it any more or less stable than having the built-in facility do it.
Be aware that if you're trying to use one of these apps to set the Interactive Governor's parameters, you're wasting your time. Not only does our Interactive Governor NOT work like you'd think - and not work like other implementations - it's totally ineffective. Every time the kernel brings another core online, it kicks all cores to the maximum allowed speed, totally sabotaging the governor's efforts. If you use Trickster to track the time at each speed, you'll see that the bulk of the time is spent either at very low speed or max speed, with all the intermediate speeds hardly used at all.
I only remember seeing one init.d file, does it matter where in that file I add the code?

Create a new file named, f'rinstance. "02gpuspeed". Put "#!/system/bin/sh" on the first line, then the code I provided on the following lines. The files will be executed in alpha-numeric order: 00banner, 02gpuspeed, 99SuperSUDaemon. Be sure to set its permissions to '755' so it is executable.
I pretty well figured that would be the case, but...
Based on my somewhat limited understanding ,If you have a utility in the Rom trying to manage the cpu speeds, and an app trying to do the same with me "choosing" to use the performance governor, conflicts are bound tio arise. Based on my pc understanding, conflict equals poor performance and instability.
And it was honestly one where I was using performance settings for the gpu, and then one of the other apps for the cpu.
So, I found that if I simply turned off the performance settings and lived with the lower gpu clock, my system ran stable. So I was asking about how to get the higher gpu clock without using the cpu overclock portion of the performance tab.
You pretty well answered that, and I thank you.
Now, do I need to include the bit in the code at the end of the first line where it says 1200 is 448, and 1250 is 520?
Also, I don't understand setting permissions to 755. I understand setting read, write, own, etc, but not 755, if that's the case, then what app do I use for that? I created the file as a blank text document on my tablet directly and input the code there, then rebooted. Or did I screw the pooch on that one?
Sadly, I know nothing about the individual governor settings within each governor configuration. Therefore, I figure that the wisest and safest course of action is to leave it alone. It's easier and safer to work with the stuff I DO know until I can get feedback and advice from someone who DOES know.
I realize that some of this may seem stupid to you, but it's the only way I know to learn.
I will make another post later when I have more time to comment on some other things I keep seeing and would like to know what to do there.

The CPU/GPU settings on the Performance page are set-and-forget values. They simply set the maximum speeds once bootup is done, and again when you display that page. They don't monitor anything - the CPU governor does that, and it is constrained by these settings. The corresponding settings in the other apps you've tried operate the same way.
You should be aware that the "performance" governor is really no governor at all. It simply sets the processor to the maximum permitted speed and never changes it. On the whole, this governor generates more heat than performance.
I found that if I simply turned off the performance settings and lived with the lower gpu clock, my system ran stable.

This strongly suggests that your device really can't handle the higher speed - at least when the CPU is running full-bore at all times. You may want to search for the postings in some of the early S7P threads where people described attaching copper foil to the SoC to dissipate excess heat.

Anything after a '#' in a shell script is a comment. As to '755', that's "read/write/execute" for the owner, and "read/execute" for the group and other users. Do a search for the 'chmod' command for more details on setting and interpreting Unix permissions.
Ok, that's fair enough.
Occasionally, I'll boot and get an error that the process called system is not responding and then it wants to know if I want to wait, or close it. It will do this every subsequent boot until I wipe cache and Dalvik (because I end up doing both out of habit) from recovery and then all is well again for several boot cycles where we start up again.
What am I missing here?
Are we free to discuss RRO theming for the S7P in this thread for now? I have been following BitSyko Development for a week or so and opted into the Layers beta and so on. I will be spending some time this week to figure this all out.

Since I'm not familiar with RRO theming how is this different from the themes released for say CM12 and the like?

Of course you're welcome to discuss RRO - especially since it gives me an opening to throw in my 2 cents
Runtime Resource Overlays provides a way to override and/or replace the "resources" (icons, layouts, colors, strings, and fixed values) that are built into an .apk file. Since the resources used by Android itself are packaged into an .apk, you can modify the OS as well as individual applications.
RRO has been around for a long time but no one other than Sony ever used it. BitSyko's greatest contribution has been to make people aware that it's a superior way to do theming which is already built into the OS and is fairly easy to use. Unlike CM's theme engine, no custom code is required.
Beyond that, their contribution is somewhat less revolutionary than their many admirers seem to think. Their efforts are directed primarily at ease of use. The Layers app is essentially a file manager that makes copying themes into place a bit easier. What the app does you can do yourself using ESFileExplorer or ADB (though without some niceties they've added).
Their tweaks to the OS are designed to make life a bit easier for themers by changing hard-coded color values into "symbolic references". In other words, rather than specifying the color for each checkbox, you say each one should be the "checkbox_color", then define what that means somewhere else. That way, rather than having to modify the color of many different checkboxes, you change the definition of "checkbox_color" once and they all become that color.
Now, as to what all this means to the Sero 7 Pro and the DoPa5 v1.0 ROM... I delayed the ROM's release for several days until I could get their patches in place and tested, so this facility is in there and ready for use. The problem is that none of the themes I've seen really support the S7P. Any color changes a theme makes will show up just fine (I'm using someone's orange theme currently). However, all the icons are targeted at higher resolution screens than ours, so the OS ignores them and uses the same ones it has always used. If you can find themes for the Nexus 7, or some of the older Asus or HP tablets that also have a 1280*800 screen (213dpi), they should work just fine.
FYI... if you want to install a theme without using Layers, create an 'overlay' directory in '/system/vendor' (i.e. '/system/vendor/overlay'). Next, get some theme packages from this thread and unzip them. Select the .apk files you want, copy them into the 'overlay' directory, then reboot. If you don't like the result, delete them and reboot again.
Perfect explanation @dolorespark on RRO. I'm hoping eventually some kind of dark holo blue theme is made for RRO as all I really need is the color scheme.

For owners of Xiaomi Air 12 or 13 that are facing static sound in Audio cause of Windows 10 please update your Realtek driver from their own website and not use windows update or general update. You need to download the latest 64bit driver dated ' 14-Jun-17 - 6.0.1.8186 '
@Wootever, sorry for my unrelated question. But, I have a Xiaomi Air 13 2016 and I've set a supervisor password when I changed to Linux. I then removed the password when I changed back to Windows 10, but it's still asking me for one...
Do you happen to know a way on how to remove the BIOS password on this laptop? I've extracted the executable from Insyde H20 A06 updater and changed the platform.ini, so it does a force flash of the password area (Password=1), however, it's still asking for one.. Any help would be greatly appreciated! Thanks in advance
@r00tPT
Try to set the password again and then set it to blank.

I wanted to reset this password altogether, so I can access my BIOS and set a new one =/

You can try to flash this default BIOS A06 Package, it will overwrite all device specific data (Serial, Windows Key, NVstore).
All settings should be set to default (including the password), but i haven't tested this (no guarantee and at your own risk).
Edit:
Don't forget to create a backup using the Backup.cmd file, it should be possible to restore the Serial number on the "empty" default BIOS.

Thank you, Wootever! I think it's worth a try.
Would it make sense to create the backup, flash the default package, confirm if there's no password and then flash back the original Xiaomi BIOS to restore the Serial number?
Sorry, as I have near to none experience related to bios. thanks once again
@r00tPT
The backup includes all current settings (including the password), restoring it would also re-enable the password protection.
I made a little script to restore the device serial from the backup.bin file.
This is necessary because the Windows Activation seems linked with the device serial number.
Edit:
Updated the script.

Wouldn't it be best to make a backup of the current bios with a flash programmer? I still haven't done this, as I'm trying to figure out what password I put.. (I basically set a supervisor password when I disabled secure boot, but then when I tried to set a new blank password it didn't change it back)
I have a friend who has the exact same laptop. Would it be fine if I made a backup of his bios and restore it into mine?
Could there be an issue or some missing information? Probably only the device serial number, which I could write again using your script? Would that be feasible?
By the way, sorry for asking these questions here/to you, but it's hard to find some guidance regarding this topic. Thanks once again
@Wootever, it worked!! You're the greatest man! I'm now able to access my BIOS again!
Is there any way to re-enable the flash protected range register again, just in case?
Wootever said:
I just got my hands on a Xiaomi Air 13 (2016 version) and wanted to share my findings.
The BIOS version of this device is A07, which is not yet made available by Xiaomi and originally, BIOS updates can only be flashed with the Insyde tools.
However, those require a valid certificate to correctly sign the binary file, thus a provided backup of version A07 won't be applicable as a update.
Intel Flash Programming tool is another alternative which allows to flash unsigned/customized versions, but in practice FPT can't access the BIOS region due to the protected range register which prohibits write access.
Code:
Error 316: Protected Range Registers are currently set by BIOS, preventing flash access.
Please contact the target system BIOS vendor for an option to disable Protected Range Registers.
Fortunately there is an undocumented variable switch that i found by coincidence which deactivates the flash protected range register.
For this i made a little tool which automatically patches the variable to allow BIOS update via FPT.
Note: modifying your BIOS is at your own discretion, i am not responsible for any damage caused by this procedure.
Download my variable patcher, extract it and execute Patcher.cmd
Reboot your device.
Download BIOS A07 for the Xiaomi Air 13 (2016)
Execute Backup.cmd to create a backup of your current BIOS.
Then execute Update.cmd to install version A07.
Use Serial.cmd to restore the device serial number from the backup BIOS.
Reboot your device.
I also made a few changes for this BIOS:
Updated microcode to 0xBA
Increased PWM frequency to 5000 Hz

I tried but I have this problem with patcher, any suggestion?
@Wootever
1) after upgrading the bios, how do i re-activate the flash protected range register?
2) do you have the default clean A07 bios (without the microcode and PWM changes)?
thank you!
May I ask if there is an easy way to unlock BIOS totally on Xiaomi Air 13? Because previously I opened a topic about it in biosmods.com , someone reached to me and told that due to write protection it needs quoting from him: "Bios mod can be flashed using SPI-programmer+SOIC8 clip only". That requires opening laptop up and connecting clip on chip physically. I love to tinker things in my laptop but that is a bit scary for me. So is there another way to do it, anyone knows??
THANK YOU!! This is pure gold! By the way, does the flag you found also unlock the ME region?
Update: nevermind. The answer is no unfortunately

No, you can flash any bios mod with the flag found by @Wootever. However, you may want to get a programmer (Altera USB blaster has cheap Chinese clones supported by flashrom) and a SOIC8 clip anyway just in case. They're dirt cheap and allow for recovery when things go wrong.
As a bonus, an external programmer enables you to get rid of the management engine.

It might be possible if the variable for ME Image Re-Flash is set:
Code:
Me FW Image Re-Flash, Variable: 0xD08
Disabled, Value: 0x0 (default)
Enabled, Value: 0x1
Variable to unlock protected range register:
Code:
BIOS SPI Lock:, Variable: 0x258
Enabled, Value: 0x1 (default)
Disabled, Value: 0x0
Edit:
Here is another variable patcher that also enables the ME Re-Flash variable.
(Note: not tested, use with caution)
Projectivy Launcher (formerly ProjecTivy Tools) now has its own dedicated thread located here.
Intro
There's so much information here that a new user could probably feel lost without the courage to read everything. So let's keep things simple : as the thread's title says, the primary aimed devices are projectors produced by Xiaomi related brands (xiaomi/fengmi/wemax), though it could probably be useful to other Android Tv models and other brands, so you might want to keep reading until the end of the introduction.
What you can find here :
Full tutorial to Googlize your chinese device with my custom made Google Apps package dedicated to Android Tv 6 (only tested on MiUi Tv, root required)
General FAQ related to these devices [post #2]
Information on how to root xiaomi/wemax/fengmi/vava projectors (and custom made TWRP for many chinese models) [post #2]
Full firmware and OTA for many models [post #2]
Google Apps / Services instructions
Here's a full tutorial to root and install Google services on your Android 6 MiUi device (ie: chinese xiaomi/fengmi/wemax).
This has been tested successfully on all devices where a custom TWRP is available below. If anything goes wrong for you, try to factory reset / clean flash
Except for "AndroidMediaShell" (Google Cast server), most (all?) features are working fine including :
Tv settings
Google Play (to let it install/update apps, please enable the Accessibility Service)
ATV remote service : if you install Google ATV remote on your smartphone, everything (including speech recognition) will work
Google Assistant : with the Accessibility Service enabled, a short press on the mic button on your stock remote control will launch Google Assistant. Then, when it's listening, press and hold the mic button while speaking and release it when done. According you've used More Locale to change to your mother tongue, this will even work in your language.
Installation steps:
root your device (see post #2) (you don't need to flash any firmware)
if not already done, install the latest version of ProjecTivy Launcher and launch it
execute Applications / install 3rd party apps, then install :
Aptoide Tv Store
ATV launcher [optional] (alternative launcher)
Youtube [optional]
MoreLocale [optional] (in case your mother tongue is not english, it will let you choose more than what's listed in Android settings)
Google Apps/services (don't forget it )
execute Applications / Freeze Stock launcher (to disable your stock home screen)
execute Applications / Freeze Stock apps (to disable most Xiaomi apps and services)
execute System / Custom Props override (to pass safetynet checks, enable more stock behavior and fix black screen with non-stock launcher)
execute System / Accessibility Service, enable the service in accessibility settings (to fix "Google Play" ability to install/update apps and to link the stock remote control "Voice recognition" button to Google Assistant as well as many other features)
[Optional] Install magisk module "Nexus Media" to change the stock bootanimation (go to Shortcuts / Magisk Manager to execute it, and then in the left menu, "Downloads" section, just install "Nexus Media")
Reboot and complete the Welcome app to setup your Google account (first and second boot will be longer than usual)
Note that an Android accessibility setting might get enabled after the first reboot when Google Apps have been installed. It'll cause green borders around buttons. Just go to settings / accessibility and disable "talkback".
Launch Google Play to update Google apps and let the update finish before exiting Google Play (if the app's accessibility service is running as it should, it will display a message when launching/exiting Google Play)
[Optional] start MoreLocale to change your language
Disable the "smart update" in the projector settings so that it doesn't try to download and install OTAs (which would just display an "error" message after each boot, when it fails to install it)
Enjoy your Google Tv device !
Important :
Once installed, don't change the device resolution in the Android Tv settings. This is not supported by the video drivers that will then only display a checkerboard. The only known solution as of now is to factory reset and start again.
Engineering Menu App Translation
Here you'll find information about xiaomi's engineering menu app.
After a bit of google translate and reverse engineering, here's a translation of the different menus, along with my own values (1st one is for "rainman", second one for "batman")
Projector information
- Brightness [1541][1610]
- DLP vendor name [APPO][APPO]
- Production Week [1812][1921]
- Contrast ratio [3828][3370]

Solid color (android) -> displays a solid color (using android system)
Solid color (projector) -> displays a solid color (native)
Other image test (android) -> displays a gradient (using android system)
Other image test (projector) -> displays a gradient (native)
Color wheel delay -> when incorrectly set, this can lead to posterization issues (gradients become unnatural and tend to display large uniform areas) [490][420]
Save color wheel delay to Android
Image mode: change the screen light intensity
- Standard
- Highlight
- Energy saving
Temperature monitoring
- ambient temperature [31][43]

Save information to projector
DLP version [major:1, minor:2, patch:5][major:7, minor:3, patch:7]
3D (when modified, need to restart to take effect) -> enable/disable 3d support

FAQ and more resources related to these devices
Differences between projector devices
Wemax One / Chinese Xiaomi Mi Laser:
They are (almost ?) the same.
Software-wise :
They are exactly the same (exaclty same codename, firmware, etc...)
Hardware-wise :
Wemax is black, Xiaomi Mi is white
Wemax is described to be 7000 lumens (1688 ansi lumens), Xiaomi mi 5000 lumens (1600 ansi lumens) (not sure if hardware is different or it's only a software parameter that changes its laser power)
Chinese Xiaomi Mi Laser/ International Xiaomi Mi Laser:
Software-wise :
Chinese one comes with android 6.0.1 and MiUI Tv (a Xiaomi UI dedicated to chinese users), International one comes with android 8.1 (more details below)
Hardware-wise :
Chinese one is equipped with DDR3 ram, International version DDR4
Chinese one has Amlogic T968 with onboard Mali T830 gpu, International one has Amlogic T962 with onboard Mali 450 gpu (somewhat less powerful, not sure it has any real world impact)
Also note than more often than not, International version will probably come with a warranty. It might be important, as few people complaining about dead white pixels seem to have a hard time getting their chinese projector repaired.
Pros/Cons of 8.1 international device / firmware (as of 10/10/2018)
This might help people choose between 02 international version and 01/wemax devices. Most of the information below come from this test. This is however subject to change as I believe Xiaomi will probably enhance their drivers in the coming monthes.
Pros
Complete software translations (no more chinese ressources)
Better user interface
Google Play Store availability
Better support of media apps that hardly work on 6.01 (Netflix, Prime Video...)
Better default colorimetry (but less configurable)
Less input lag (75,6 ms vs 126,6 ms) fixed on 1218+ firmwares
Cons
No 3d support
Less options related to display settings (missing RGB levels)
Worse image quality as noise reduction and sharpness seem to be less effective than on the 01 version
Judder and image tearing during media playback
Can devices international firmware be flashed on chinese models
No :
- devices hardware is not exactly the same
- partition layout is different (android 8.x requires a vendor partition)
- we don't have access to any international firmware
Supported video modes
EDID data here for "rainman" (1080p version) : View attachment edid-rainman-report.txt
EDID data here for "batman" (2160p version) : View attachment edid-batman-report.txt
EDID data here for "jerry" (2160p version) : View attachment edid-jerry-report.txt
EDID data extracted with HDMI 2.0 enabled from /sys/devices/hdmirx.28/hdmirx/hdmirx0/edid and analyzed with Advantiv EDID Editor 1.01.0268
Is my 4K device really displaying in 2160p ? Why does YouTube refuse to stream 4k ?
- Yes.
- Blame it on Google. Or AmLogic.
More details here.
Note : more recent devices such as Fengmi Cinema 4k pro (codename Jerry) based on Amlogic T972 soc don't have this limitation (they support VP9 hardware accelerated decoding)(but seem to lack 3D support)
ALR Screens
Interesting post from @servo386 regarding Ambient Light Rejection screens dedicated to UST devices.
Rainbow effect
I see many questions regarding rainbow effect (due to the DLP technology used). What I can say is that I never saw anybody complaining about it on the Mi laser projectors. A previous projector I owned (an Optoma) was also using DLP technology and I could see this rainbow effect from time to time. In the case of rainman/batman, I've never been able to see it.
Input lag
The Mi laser projectors have relatively high input lag (150/175 ms). Firmware updates sometimes help. As of september 2019, the lowest input lag can be obtained on "Monitor" or "Game" mode (approximately 100ms on batman, 75ms on rainman). If your device is rooted and you're using the ProjecTivy Tools, you can also use the "User" mode, and long press the "back" button to get down to the same input lag as "Monitor" mode, with the benefits of keeping your calibration settings.
Dead/black/white pixels
One owner of the chinese version here (french) who had a dead pixel managed to fix it by increasing RGB custom settings above 1500 for some time (don't know how long). When reverting to previous values, the white pixel had disappeared. Didn't work out for another user, but it might be worth a try.
This might change in the future (in this case, please keep me informed), but trying to manually repair by changing the chip is a dead end. It's not the usual Texas Instrument DLP4710FQL, but the DLP4711FQL (source), which is not compatible(source) and can't be bought online.
Display issues with MJJGTYDS01FM (Xiaomi branded 4k model)
Many display issues can affect this device : taking time (minutes) to start displaying something, displaying only half image or white lines/bands... Most issues appear when the device is cold and get fixed when it has heat up.
Seems like a hardware design issue that can be fixed by removing a few screws. More information here. After this, like your projector, you won't be screwed anymore
More details can be found here as well.
HDMI input ports don't work anymore in International devices after upgrade
Install the tools, launch engineering menu and select "HDCP key reset" (thanks @xthing)
Cross platform Remote Control
I also developped a simple web based remote control for MiUI TV (Xiaomi with chinese interface) based android devices (such as projectors, boxes, TVs).
No need to install anything special on your controlled device, this website/webapp communicates with the MiUI TV internal web server to send events to your device.
It should be compatible with anything running a web browser (provided it's quite up to date): Android, iPhone/iPad, PC/Mac computers...
Just head to http://mireco.hopto.org, configure your device local IP address and you're good to go.
More details on GitHub.
Other Tools
MiiInfo from 4PDA user Loly, shows various details concerning your projector.
Firmware updates after rooting and/or installing Google Apps
Firmware updates won't install if files on your system or kernel partition are modified. Using the ProjecTivy Tools and installing the Google apps won't modify existing system files, but rooting with magisk will modify the kernel. So before any update, you have to restore your kernel (aka "boot") partition using TWRP, and then reapply Magisk once update is done.
Google Apps Issues / not yet working
Amazon Prime video : it's been reported that Amazon purposefully blocks the app on projectors. The app loads, but refuses to stream videos. Some previous versions (requiring mouse for some features) work fine though. You can install the most recent compatible one using the ProjecTivy Tools.
Netflix : No recent Tv version seems to work. Some previous versions (requiring mouse for some features) work fine though. You can install the most recent compatible one using the ProjecTivy Tools. Anyway, due to missing full widevine support, full hd / 4k will probably never work.
Chromecast framework (Google Cast Server, aka AndroidMediaShell) isn't supported (devices need to be approved by Google to be supported)
Recovery
To go into recovery, turn off your projector, unplug it, hold down OK and BACK buttons simultaneously (OK and HOME for anglee) on your remote and plug back your projector while still holding them down.
Warning : don't "hot-unplug" it, turn it off before, or it won't work.
If you're looking for TWRP, have a look a few points below
Unroot
Start the Magisk Manager app and select uninstall
OR
Boot Twrp and reflash the Boot (kernel) backup you made just before installing Magisk
Factory Reset
Reflash the full stock firmware available below in this post. This doesn't require any intervention on your part so it should work even if you can't see the display
OR
Boot the stock recovery and select the "reset device" (not sure of the exact terms) option
Root
Note : both methods below work for rainman as well as batman (4k) devices.
Easy Method:
This method doesn't require any special hardware, only the TWRP I made (3.2.2.0, based on stock recovery files), along with another config file.
Thanks to @cr4zyw3ld3r who made a video tutorial based on the following instructions.
For french people, here you can find a tutorial made by Pierre. Thanks to him.
Extract this file View attachment batman_twrp_3.2.2.0b.zip (for "batman" 4k), this file View attachment zodiac_twrp_3.2.2.0.zip (for "zodiac"), or this file View attachment rainman_twrp_3.2.2.0.zip (for "rainman" 1080p and most other devices such as conan) at the root of your (FAT32 formatted) USB drive, where you also place the latest magisk version (magisk 20+ version support has been added on tools v3.5+), and plug it into your projector (I used the right USB port)
I also built (but not tested) a twrp for Vava projectors here : View attachment vava_twrp_3.2.2.0b.zip (please report if it works).
Download ADB for your computer (check here)
Start command line (terminal)
Enable USB debugging in Android settings / developer options (you can access them from the projectivy tools)
Type "adb connect IP_OF_YOUR_DEVICE:5555" to connect through the network
Type "adb reboot update" (This will restart your device and make it boot the TWRP on the USB drive.)
Once in TWRP a mouse will be required. Make backups if you wish (at least "boot" partition that you'll need to restore before applying any OTA update), and then mount SYSTEM, and install magisk in order to root the device (it will be in "/udisk" and will be called Magisk-......zip)
Note : to thank the donors, I also developed an application that installs on your Android smartphone, which automates steps 1 to 6. There is no need for computer or custom command lines in this case. Once the app is connected to your projector, you're only one button click away from TWRP.
Note : if it still boots to stock recovery and not twrp, make sure you extracted the zip and not only copied it to your usb drive. If it's extracted correctly but still doesn't work, try another usb drive, a few people reported that this fixed their issue (some users had to try 3 or 4 usb devices before finding one the works).
Old Method:
With the correct hardware, you can root your device, following this tutorial from @servo386
To simplifiy the rooting process described in the link above :
Extract this file View attachment twrp-files.zip at the root of your USB drive, where you also place the latest magisk version (as of now 19.3), and plug it into your projector
Follow the steps described in the tutorial, up to the point where you have a root console access in recovery
Then, according you've plugged your USB drive before starting your device, just type ". /udisk/twrp.sh" in the root console. This will copy the necessary files and automatically run twrp, reducing the number of steps (and potential mistakes) to root your device.
Once in TWRP, make backups if you wish, and then mount SYSTEM, and install magisk in order to root the device (it will be in "/udisk" and will be called Magisk-.....zip)
Roms / Dumps
Due to issues on the new XDA 2021 website (preventing edition of long posts containing many links), full firmwares and OTA have been (temporarily ?) moved to post #4.
You'll have to scroll down by yourself, I can't even add a link to it
Spocky great work this looks fantastic,
you highlighted that you're not yet rooted and I've tried a few things so far that haven't worked however a few days ago one of the guys on the XDA forums has managed to access command line probably using the jtag points on the board. It's quite likely but this is a good way to get a ADB and then root access, and therefore if uses nandroid type tools he should be able to complete a full dump of the ROM.
I have a Chinese projector with same firmware as your own, but I'm hoping we can load the Android TV launcher interface as in the international version.
Let me know if you need anything specific tested.
Roms / Dumps
Warning: Full roms below can help you recover your device if you're stuck with a non functional projector. However, if your device shipped with a more recent firmware than the one you're trying to flash and has a more recent hardware revision, you might have display issues. So before flashing a full firmware, please try to boot to recovery and use the "wipe all data" option. On MiTv devices, this will basically do the same thing (this will automatically flash the device with the stock shipped firmware, which is present on the /backup partition).

How to flash :
[OTA only] be sure your current firmware version is the same as the "from" version specified above.
Download and extract the zip file to the root of a USB thumb device and follow the procedure to boot into recovery mode. The full firmware or OTA update will be automatically installed (approximately 5 minutes will be necessary). You shouldn't lose any data (well, unless there's a power cut during the update process ). Even after flashing the full firmware, I still had my apps installed. I suppose you need to factory reset if you want a clean install.
Those willing to reinstall from scratch will need to use the "wipe all data" from the recovery menu. If you can't acces it somehow, you can try flashing a full rom (935 for rainman, 312 for batman *mijia* or 494 for batman *fengmi/wemax*), and then flash to the latest available OTA (you might need to chain flash if no direct OTA is available from you stock full rom to the rom you're targeting).
Please note that for a few users, the OTA won't install (it will stop during the update process with a chinese message). It's due to the fact that during installation, a check on the system files and kernel is made and at least one could not pass. This will be the case if you have rooted your device (only kernel is modified then). In that case, if you want to apply the update, you'll need to revert to an unmodified kernel/system. If you didn't modify system partition, restoring kernel partition (boot.img) should be enough (or uninstall Magisk from magisk manager app). If not, try restoring system.img also. If nothing works, reinstall from scratch (see just above)
wemax 7000
Great job !
I will try it tomorrow on my wemax 7000.
Let me know how I can help.
Should I also make a dump of my Chinese rom ?
How did you dump yours ?
I also badly hope to get the android tv rom working with the play store.
Thanks a lot !
Getting a wemax dump would be great indeed !
I did it with adb, connected wirelessly to my computer.
To do the same :
- download adb for your system
- connect wirelessly by using "adb connect IP.OF.YOUR.WEMAX"
- create a folder for the dump on your computer : "mkdir dump"
- go in it : "cd dump"
- pull system files : "adb pull /system"
Then every file that doesn't require root access will be downloaded to your computer. Just make a zip of it and upload it somewhere.
If it feels too complex for you, wait for a few days, I'll probably upload a tool to make an archive and automatically upload it somewhere. I just need to fix a few things before.
Hello, I'm the one who got root via the HDMI->UART diagnostic bridge. All credit goes to @loly though on 4PDA, who is the person who actually figured out this process on his Xiaomi Mi TV 4A, which has a similar chip to this projector so I took a guess that it would work too.
The posts I made on AVSforum are pretty long and lots of pictures and formatting so for now im just gonna link it but hopefully I can easily copy over the posts and make them here too.

Hi,
I installed the app and got a Chinese popup telling me that what I was doing was forbidden to users.
The menu is in Chinese too and I tried translating it with google translate but It's very tedious and I'm not very confident going through the menus.
Thanks a lot for the procedure for the backup.
I will cleanup all the installed apps and maybe reset it completely so that i can share the backup online.
If you're going to prepare a tool to do so, I will wait so I can test it as well.
Let me know if I can help you by sending you more infos.

Xiaomi Mi Laser Root Procedure
This is a long one. Also it was originally written for an audience who may have not been as familiar with Android/Linux commands so it has lots of explanation that might feel out of place on XDA.
So first and foremost ALL CREDIT BELONGS TO @loly ON THE 4PDA.RU FORUM WHO ACTUALLY DISCOVERED THIS PROCESS
https://4pda.ru/forum/index.php?showtopic=810785&st=3260#entry75802829
I definitely am just a copy cat who guessed that his process would also work on this device since their both Xiaomi TV devices with Amlogic T96* boards.
So if you read his post (which you definitely should in addition to this post in order to get the full picture of how this is done), you'll see that this is quite complicated and a kind of high level hack. I hope I'll be able to explain it enough and walk through it enough for it be fairly accessible for less technically inclined people who want to root their Xiaomi projectors.
What is required:
1. HDMI cable you can chop up or an HDMI breakout cable like this one: https://www.amazon.com/Adapter-signals-Terminal-Breakout-Connector/dp/B01CU9SHOO/
2. UART to USB adapter cable/board like this one: https://www.amazon.com/Adapter-Serial-Converter-Development-Projects/dp/B075N82CDL though there are cheaper options available
3. Cables/wires to connect both things. The USB UART package above comes with some, though you'll have to strip the ends to screw them into the terminals of the HDMI breakout board.
4. A spare USB drive
5. A computer to use the USB to UART adapter and a terminal program, i am using Putty.
So the basic idea behind this is that one of the HDMI ports (HDMI 1 in this case, the one closest to the edge) also serves as a diagnostic/UART port via 3 of the 19 pins of the HDMI. When this HDMI port is properly wired to the UART adapter, and you have a terminal open observing said port, upon boot the machine reads out all its startup stuff and when booting into recovery, gives you a completely liberated UNIX terminal that accepts input from the UART terminal, with full root privileges and busybox! As @loly says in his post, here we thank the people at Xiaomi for not bothering to secure this section and giving us full diagnostic root access with busybox. This is almost surely the way the developers of this machine would interact with this machine and developed for it. So let me try to explain how this works and how we get to TWRP and root.
Steps:
1. We need to properly connect the correct pins on the HDMI cable to the correct pins on the UART.
Here I am going to re-post some of @loly's images from the original thread, so all credit goes to him.
Here we see the pins we need. Pin 14 is our VCC, which in this 5v (the UART adapter im using has a switch for 3.3v or 5v, this switch needs to be set to 5v!) Pin 15 is the receive pin and Pin 16 is the transmit pin
The fourth lead we need is the GND (ground), which in the case of an HDMI cable is usually an un-shielded wire that connects to the the case of the connector itself.
I'm going to stop here for a sec and say this is why it's alot easier to use the HDMI breakout board over trying strip an HDMI cable and finding which wire corresponds to which pin (you need a multi-meter to do that)
its a small investment but it makes everything ALOT easier. On the HDMI breakout board, the ground terminal is pin 20.
the corresponding pins on the UART are pretty straightforward. VCC goes to VCC on the UART, pretty straightforward, on the other hand the RX pin of the HDMI (pin 15) goes on the TX OF THE UART makes sense right? the receiever of the HDMI should be listening to the transmitter of the UART and vice versa, so the TX pin of the HDMI goes on the RX pin of the UART. The GND pin (pin 20 on breakout board) goes to the GND on the UART.
Here's my setup. Sorry for the not very great picture. The terminal blocks on the HDMI breakout board work basically like you were connecting speakers to an amp, you unscrew the terminal till you see a little metal hole and you stick the stripped tip of the cable into the hole and screw the terminal back up till its snuggly holding onto the cable. You can use a multi-meter if you have one to make sure the wire is making contact with the terminal and even test the exact pin with the cable to make sure the connection goes all the way. If you're cable is making contact with the metal of the terminal, it is almost certainly correctly making contact with the actual HDMI pin, barring maybe a badly manufactured breakout board. I used spare MALE end pin connector cables to strip the ends and stick in the terminals, and connected them to the FEMALE connectors that came with the UART adapter. You don't necessarily have to do it this way, you can directly strip one of the female ends of the cable and connect the other female end to the pins on the UART, but you'll have a pretty short cable from HDMI to USB and you'll probably need a USB extension to comfortably use it with a computer.
So now you have you're HDMI diagnostic cable!
2. Setup your computer for UART and Putty.
Connect your UART to USB adapter to your computer. In Windows 10, it should automatically install drivers, but if it doesn't, your device should come with a link or something to download the drivers. I'm not going to get into the specific of how to install drivers on Windows computers but needless to say, you need to get the computer to recognize the device and properly utilize it via the drivers. Once you have it properly installed on the machine, it should show up in your device manager under Ports (COM & LPT) or something similar.
this is important because we need to 1. determine what COM port you're device is on and 2. change the baud setting.
So in the photo you see that it tells you what COM port is, which we need for later.
Now you need to go into the settings of the device and go into Port Settings tab
WE NEED TO SET THE BITS PER SECOND TO 115200!
Very important!
Setting up putty:
Basically open up putty and put the button on Serial, set the speed to 115200 and in the SERIAL LINE put the correct COM port number (COM1, COM2, COM3, ect)
Pressing enter on this should open a big blank black terminal with no activity. Thats good because its working. If it wasn't, you'd get an error about not reaching COM port or something.
3. Testing out our diagnostic cable with UART and Putty
Unplug your projector. Plug your HDMI into HDMI port 1 and connect your USB to computer. Open up a Putty terminal session as outlined above. If you get a big black screen with no errors upon launching the terminal, youre in a good spot.
Plug in the Projector. If you've done everything right you should get a big long readout of text scrolling by as it boots. If you get this, congratulations, you've accessed the diagnostic correctly!
The final step for actually accessing the usable terminal is doing the same but while booting into recovery.
4. Booting into recovery
Turn off your projector. Unplug it. Take your remote and hold down THE OK BUTTON and the BACK BUTTON at the same time. While still holding this, plug in the projector. It should start booting up. You're terminal Putty should be going crazy with text readout like last time. After a few seconds, let go of the buttons. Your projector should eventually end up on the Recovery menu, which is just some big buttons in english and chinese with a black background.

After the readout in the terminal has stopped, press enter. It should skip to a new line with
Code:
~#
Tada, root! You're officially in a fully privileged root terminal in the underlying unix system of the projector.
This is the hard part of all this. If you've successfully reached this part, you've won the battle. Everything from here on out is just a couple of commands and some files being downloaded and transferred.
Launching TWRP, making a Nand dump, flashing Magisk, getting Root
So if you indeed have reached the point where, from recovery, you can enter commands into the terminal session, now the question what to with it. The answer is basically anything you want, but let's launch TWRP and go from there.
So here is where you need to download this zip file, also courtesy of @loly from the original russian thread. He went to the trouble of (I'm assuming) compiling his own TWRP for Xiaomi Mi TV 4A which, which as I've mentioned before it's chip (Amlogic T962) is the in the same family as the chip in our projector (Amlogic T968) so it works. That said I would say right now this is not a full TWRP specially made for our projectors, so we aren't going to flash it. We are going to launch it from the terminal (as per @loly's instructions) and use it, but not flash it to our recovery partition. This is for the best right now because a. it's not for our device and b. stock recovery allows us to install OTA updates if they come in the future
View attachment TWRP.zip
my attached version has only the twrp folders, no recovery image, no magisk included.
https://yadi.sk/d/uTUrwdAl3ZyUcN <---- original zip
Download that zip file and unzip its contents right into your USB drive, so that the folder `twrp` (lowercase) is in the root of your drive . This will make it easier to type the commands exactly as they appear later. Ignore the recovery.img, we're not flashing this onto this device.
The magisk included in the TWRP.zip is old by this point. I flashed Magisk 17.1 flashable zip, the latest stable as of this writing. Get it here https://github.com/topjohnwu/Magisk/releases/download/v17.1/Magisk-v17.1.zip and put it on the flash drive.
A quick primer, this terminal instance has Busybox installed. Busybox is a "swiss army knife" of unix command like binaries because it packages all the standard linux commands into one single binary, so instead of calling
Code:
ls
to see the contents of the directory you instead would type
Code:
busybox ls
and it would work.
One last thing before I continue: while doing terminal stuff, I quickly learned that occasionally the terminal would throw up all kinds of gibberish which, as far as I can tell, had no rhyme or reason to it and more important had no discernible effect on what i was doing. Its a weird bug that maybe only ill experience because of my setup, I don't know. It would take two forms, one where it would throw up a bunch of lines of technical sounding text which included references to errors and such, but would ever actually affect anything. the other is when it would randomly spit out something like "hotplug_9" and again, id just press enter to get to the new line and nothing would have been affected. Don't be alarmed.
1. Insert USB drive into projector
Take your USB and plug it in. On your terminal, you should a small flurry of activity and references to a new device located at
Code:
/dev/block/sda1
or
Code:
/dev/block/sda2
take note of this, because this is the physical address of your USB drive thats going to have to be mounted. sda1 is the typical one, in my experience.
2. Mount USB and copy over files
This is just a series of commands, type them in precisely as I have them here, assuming you've maintained the same file structure on your USB stick as I did, unzipped the TWRP.zip straight onto the root of the USB.
Code:
busybox mount /dev/block/sda1 /sdcard
This mounts your USB device to the folder `/sdcard' if you're usb is at a different device location, change it appropriately.
Code:
busybox ls /sdcard
Just do a quick readout of the contents of `/sdcard` to make sure it properly mounted. you should see the contents of your USB drive listed here
Code:
busybox cp -r /sdcard/twrp/twres /
Copy the folder `twres` from the USB to the root of your projector
Code:
busybox cp -r /sdcard/twrp/license /
Copy the folder `license` to the root of your projector
Code:
busybox cp -rf /sdcard/twrp/etc/* /etc
Copy the contents of the folder `etc` to the etc directory on your projector
Code:
busybox cp -rf /sdcard/twrp/sbin/* /sbin
Copy the contents of the folder `sbin` to the sbin directory on your projector
Code:
busybox chmod -R 0750 /sbin
Change the permissions of the sbin folder to its all executable
So thats all the copying, now the moment of truth
3. Launch TWRP
YOU NEED A MOUSE PLUGGED INTO THE PROJECTOR TO NAVIGATE TWRP!
Code:
/sbin/run.sh
after hitting enter on this command, TWRP should boot up on your screen (and a bit of readout in your terminal
IF TWRP DOESN'T LAUNCH, YOU'VE DONE SOMETHING WRONG. GO BACK AND CHECK EVERYTHING.
I hope if you're doing this you're somewhat familiar with TWRP, but I will try to walk through the 2 most important things to do
4. Rom backup
One of the big buttons is BACKUP, go there and you'll see a series of check boxes for each of your partitions (boot, bootloader, recovery, system, ect). Select the ones you want (I selected all but I know for a fact this is unnecessary but I did't want to overlook anything and I didn't want to guess which I could ignore). It should ask you where to save the backup, select either the USB drive or internal memory and pick a folder. Slide over the thing to begin backup. It'll take a bit but eventually it should finish. Tada, you have a backup of your entire device.
5. Flash Magisk (ie get root)
This is the big kahuna, the one that unlocks everything OS-wide. Before trying to flash Magisk, we need to mount the system partition. This was big headache for me cause I didn't know why all the commands in the install scripts for failing and it was because /system/bin contains all the commands/binaries that Magisk installer script uses to do its stuff, so thats why we need to mount it first before trying anything. Go to the big MOUNT button and you should see checks next to USB and INTERNAL MEMORY or something to that effect, i can't remember off the top of my head. Almost certainly SYSTEM does not have a check next to it, meaning its not mounted. Click the check mark next to SYSTEM and that should be it, it is now mounted.
There is a quick way to check this, which is to go to ADVANCED>TERMINAL and in the terminal type
Code:
mount
if you get any sort of read out of device partitions, you're good, that means the mount command is working meaning the /system/bin is being made available to TWRP to execute commands.
With that done, go over to the INSTALL button on the home screen and navigate over to your USB stick and find the Magisk 17.1.zip. Select it. Check the check mark to reboot after install. Slide over the slider to begin the install. Moment of truth, you'll likely get to errors in big red text something like MOUNT -O BIND /SDCARD FAILED or something, thats fine, ignore it. It should go onto to say
Code:
|----Magisk Installer Script 17.1----|
or something like that, that means its doing its thing. Everything should go well and it should ask to reboot.
6. Verify root
Once you boot into the Xiaomi home screen after flashing Magisk, you should get some kind of thing asking to confirm that you want to install the application. That application is the Magisk Manager, which means you did it, Magisk installed successfully!
Go ahead and install some app that you know asks for superuser and it should prompt you for superuser access, grant it. You did it, you're root!

There's really not much this app can break (and not much to change neither). Most interesting thing would be the information page, along with the temperature page.
Concerning the dump, no need to cleanup anything as user data is stored :
- in /sdcard (internal memory) mount
- in app folder which can't be accessed without root
Dumping /system won't access any of them, this will basically only copy files that where part of the last firmware installed on your device.
As for my app, not sure I'll have time to finish it before next week.

Thank you for your time adding this post here and for the tests you've made to root this device. That's really cool !
If you have time, don't hesitate to post a full dump of your rom, we might learn a bit more than with mine.
Also I have not read your post from my computer so it might just be a bug, but Tapatalk reports your twrp.zip file as being 5 bytes only.
Edit: nevermind, your twrp is fine
I've ripped the "backup" archive that is a flashable update image of the stock image, used by the machine when you do "system restore" in recovery.
Basically here is the stock rom for the model 01 "rainmain" at last.

#1 and #2 posts edited, adding many details, roms links...
Hi,
Thanks again guys for the effort you put on this.
I bought the hdmi breakout and a usb ttl and followed the instructions (very clear, thanks again for this) and backed up everything as you did but didn't root the device yet.
Are my .win backup files usefull to anyone (Wemax 7000) or do you need me to root the device to make the dump as spocky12 suggested?
I don't know how interesting my Chinese rom would be to others though...
Anyway it's good to know that we could flash the device with the android 8.1 rom when it will be available.
If you know anyone having the english rom, I would be willing to send him my cable to make a backup of his.
Cheers

Are my .win backup files usefull to anyone (Wemax 7000) or do you need me to root the device to make the dump as spocky12 suggested?
I don't know how interesting my Chinese rom would be to others though...
Anyway it's good to know that we could flash the device with the android 8.1 rom when it will be available.
If you know anyone having the english rom, I would be willing to send him my cable to make a backup of his.
Cheers

Thank you for your message. Glad you managed to follow @servo386's intructions. If you don't mind, I'd be interested in your .win files, to validate a few assumptions I have.
Concerning the international model, unfortunately, as of now, no owner seems to be willing to take the plunge. Hopefully it'll change soon enough.
For hackers out there, I found a tool that might prove helpful to build customs roms or repack roms using international model paritions (once somebody will dump it).
It's AMLogic Tools 5.5.0 that can be found here. I haven't had time to read the full thread yet. There might be valuable information there.
You can use it with the stock rom (935) from @servo386 that I specifically extracted and repacked with latest (1074) recovery (stock "backup" rom does not ship with recovery, which is needed by AmLogic Tools).
You can use the "customization tool" to easily extract/repack a rom that can be flashed in recovery or with special Amlogic USB flash tool.
There is also a tool that can "convert" a classic recovery to TWRP recovery (but supposedly only works with S905/S912. Might be interesting to check what is needed to make it work on our chip)
Unfortunately, I'm not an expert at building custom roms in Android (the latest custom rom I built was for Windows Mobile 6.1) (Great. I'm feeling old now ). I'm not quite sure what is allowed to be flashed with our bootloader. I haven't tried to flash anything yet, as if I brick the projector, my wife will probably kill me . But I suppose that if the custom built firmware doesn't embed bootloader/recovery, most errors will be recoverable by flashing the stock rom again.
If you want to test, don't forget to call the built rom "update-rainman.zip" and to put it in the root folder of an USB device along with this file.
Hey, it's me again
Some of you might be interested in an update to a more recent (but beta) version for wemax/chinese Mi projector.
I added a link to OTA from 1074 (1.3.74, built on May 4th) to 1189 (1.3.95d, built on Oct 12th) in the second post (yes, it's still Android 6.0.1)
To install it, just extract the zip file to the root of a USB thumb device and follow the procedure to boot into recovery mode. The update will be automatically installed (approximately 5 minutes will be necessary). You won't lose any data (well, unless there's a power cut during the update process ).
I haven't tested much, but here are the changes I've seen :
- most menus (settings) are in english now
- new settings options (the only one still in chinese) : automatic power off after 10 minutes of inactivity (doesn't seem to work, though)
- new volume UI
- Karaoke app added
- new animations during recovery installation
- wmv3 video format support added
As a side note, I've found a reference to an upcoming Xiaomi Laser projector in code, that wasn't there before : MiProjLAS2, codename batman.

Thank you so much for your work.
The file to update to the current beta is only 55Byte in size. Nothing happens when plugging in the USB stick.
===============================
I had two xiaomi laser projectors so far.
Projector 1 had dead pixels after 3 weeks of use. Here are the key figures from the engineering menu.
Here projector number 331 from 2018 calendar week 3:
It had a great contrast: 5382:1
The one complained to gearbest and got an exchange(Projector 2).
Here projector number 1196 from 2018 calendar week 13:
Contrast: 2441:1
Projector 2 unfortunately has too little contrast and is very blurred at the edges. Currently exchange projector 3 is on its way.

Thanks for your message. Comparing data from different projectors is really interesting.
Concerning the link, my bad, I've updated it to the right file, you can download it again if you wish.
Thanks spocky12, just loading the beta
When Projektor3 has arrived, I put the values from the menu here.
Edit: I copied the unzipped archive into the root of the USB stick. But nothing happens when inserting the stick.

You have to follow the procedure to boot into recovery. Either use :
- "ADB reboot recovery" if you have ADB
or
- unplug your projector, keep your remote "ok" and "back" pressed and plug your projector back in. It will boot into recovery and automatically start the update process.
(Your usb thumb drive should be formatted in fat32 and both files placed in its root folder).
