Tegra Note 7 5.1- How Do I Downgrade From Lollipop? - Nvidia Tegra Note 7

How do I downgrade from Lollipop?
So I remember my excitement when I saw that my beloved Tegra Note 7 showed me that the 5.1 OTA is available. Needless to say, the excitement died down after a week or so of using the tablet. The problem that bothers me the most is battery drain. In just about 10 hours in standby mode with WiFi off, my battery reduced 13%. I take it off the charger at 100%, WiFi on, in standby mode and viola, in 10 minutes, 3-4% battery drain with no activity at all. Now I hardly get more than 2-3 hours of activity out of it but when I was using Kitkat, oh boy. 2 days in standby with WiFi off and 1-2% battery loss.....Amazing. Also, I miss the power control so much <3 (I really don't think the Activity Launcher way to get the SHIELD Power Control Menu works at all)
Now I really want to downgrade it to Kitkat but have absolutely no clue how to do so. I'm not rooted currently and I've tried searching in the forum for existing topics for but couldn't find any. It'd be great if someone wrote a 'For Dummies' guide as to how to downgrade from Lollipop on an unrooted device in the simplest way possible.

Yeah Kitkat is better than Lollipop at the moment. You need to get a custom recovery on it and flash one of the stock ROMs. You don't actually need to root Android for any of this.
The "Super Tool" will get the custom recovery on it (CWM or TWRP). Note that you will lose all data on the tablet when you unlock the bootloader. Also, the NV USB drivers for Windows are unsigned and so you will probably need to boot Windows into a mode that disables the driver signing check (Win8/10).

Then you can put one of these stock ROMs on a SD card and flash them within that recovery. It's very easy to go between ROMs this way.

And of course be warned that there is always the possibility that something could go horribly wrong and kill your tablet. It went smoothly enough for me though.

Back to KitKat! (+Easy guide for others!)
Thanks a lot for the help swaaye!
I'm finally back on 4.4.2 and damn, the amazing standby times are back. I'm not so sure how I feel about the screen on time as I was expecting more since I've kinda forgotten how KitKat was originally. Anyway, a run time of 1 Day and 12 hours with WiFi on 75% of the time and a screen on time of 2.5 hours is miles miles miiiiiiiiles ahead of Lollipop! (22% Battery remaining). I'm back to the Antutu benchmark of 35K vs Lollipop's 40K/40K+ I'm mad for theoretical performance so I kinda miss that having those beautiful numbers flash on my screen. Regardless, I'll take much much better battery life over those 'numbers' any day of the week. Enough time wasting, lets get on with the guide! (I'm sure this has been posted before but I'll try to cover 1-2 of the issues that I encountered that others might too)
STEP 1 - Download Nvidia Tegra Note 7 Super Tool 2.5.zip (Android 4.4.2) I downloaded version 3.0 but that only restored to Stock 5.1. I'm not sure about the versions between 2.5-3.0 as I randomly downloaded 2.5 and it worked so I didn't bother checking the others for Android versions/software changes.
STEP 2 - Go to Device Manager -> Go into the properties options of the Tegra Note (Right Click) -> Hardware -> Properties -> Hardware -> Driver -> Update Driver -> Locate Drivers Manually -> Locate the folder MicrosoftWindows_NvidiaUSBDrivers_Rel20131017 in the extracted folder of the downloaded Super Tool 2.5 -> Include SubFolders and viola! The software should now be installed. [I’M NOT ENTIRELY SURE IF OPTION 1 IN THE SUPER TOOL– ADB & FASTBOOT DRIVER INSTALL DOES THE SAME THING SINCE I INSTALLED MY DRIVERS MANUALLY. ALTHOUGH, I THINK IT SHOULD DO STEP 2 BY ITSELF]
STEP 3 - Just unlock your bootloader and restore to 4.4.2 with the help of this video (youtube. c o m /watch?v=oAp-P-yUSaA)
P.S. - Thanks a lot for the amazing work to RootJunky and all others involved!

Iconia A500 freezing

Since my Iconia updated to ICS it "freezes" when left unattended and powered on for a little while. The only way to bring it back is to hold the power button down for about 8 seconds, release it and then hold it down again for about 4 seconds. It then starts back up.
I have searched many forums and have tried the following;
1. Factory reset (many times)
2. Not loading apps
3. Turning blue tooth on
4. Setting WiFi policy to never sleep
5. Setting WiFi policy to sleep when screen is off
6. Disabling Google+
7. Setting display sleep to 30 minutes
8. Setting display sleep to never
9. Turn off sync for all accounts
10. Removing SD card
This has gotten beyond frustrating and has led to a tablet that, in many ways, is useless to me now. Does anyone have any other thoughts?
I am not very technological so I have never considered rooting but, if there is a rock solid way to do so and solid ROM I may consider it.
Thank you!

Do a search for SOD, sleep of death.
Are you on ota ics...? I take it you did not have that problem on HC
I have had that problems on some software versions and not others, currently on ota ics stock no root and have that problem.

The only trouble you will have is not following the install instructions in the OP of whichever ROM you choose.
You must do a full wipe/format of /data/media and /flexrom partitions - both before and after flashing yr rom .
Updating the Bootloader to the patched ICS should resolve the sleep of death issues.
I can only suggest the rom I have used which is mainly the flexreaper series - atm I am running the RE-FLEXxx 4.0.4 rom of civato's and couldnt be happier - its smooth and snappy, has great battery life and I've had no issues - oh yes I did, boot looped after flashing but I did another wipe and all was well...
Link to Civatos "Flex series" Roms Most of the recent roms need the ICS patched bootloader. But FLEXREAPER-RF1_rv3-CUSTOM-ICS can be run on the HC BL but as I said before it is best to update once you're feeling up to it
Thors Rom from Tegra owners (google) is a very stable and popular rom based on CM9
So to recap:
You will have issues running ICS on the HC bootloader
Use cwm 1.7.3 to do a nandroid backup-it should generate a "uid.txt" file in yr backup folder and also displays it on-screen
Your HC uid is VITAL to unbrick in case things go pear shaped
Now that you've done this you can look at rooting and flashing a custom recovery.
Root It - icsRoot from Blackthund3r
Install a custom recovery - Flash CWM 1.7.3 custom recovery to backup/restore, flash roms etc, get yr uid OR
download Acer Recovery Installer to install the "recovery" for you
DONE!!
You can flash any ROM that is compatible with the HC BL - the OP will always say if it is or not.
Just one more thing - there are a variety of ways of rooting and flashing the BL you can go about it manually or use one of the many automated tools to do it for you. It depends on what you feel comfortable with!!
The major steps to flash the patched bootloader - (from civatos guide)
Step 1 - Make sure the acer and android drivers are installed
Step 2 - Retrieve your cpuid
Step 3 - Generate the SBK (Secure Boot Key) from Vaches Site
Step 4 - Flash yr ICS Rom of choice
Step 5 - Put yr tab in apx mode
Step 6 - Flash the Bootloader via manual nvflash (civato's guide) or
apxFlash Tool (Blackthund3r) or
if you want to automate everything from root to b/l then gersma's afterOTA tool is the one for you - all the links you need you can get from the original link i posted.
If you need further help just ask. Good Luck

[Q] ZTE Grand X Pro custom rom ?

hi, i have zte grand x pro but he have was a little laggy, when will be some rom available for download ? soon ?
thank you so much
well, that makes whole total of 2 of us who eagerly await custom rom for this great phone.:good:
as for lag, change launcher and disable live wallpaper. i remember when i first powered it up, i thought "what the fluf did i just buy?!?!" now i'm running holo launcher and have never regreted buying it...
anyway, fingers crossed for some poor soul who's willing to sink many hours of rom baking just for our basketball team...oh wait... we're even less than that...:laugh::laugh:
*three of us :good: Holo launcher solved the speed problems for me too, and it's a really nice phone
What characteristics has this ROM? Is it geared toward fast performance or features? Which version of Android?
Thanks

it runs stock ICS 4.0.4., with very little bloatware from zte (ZTE launcher already mentioned). the phone feels very quick and responsive, most noticeable for me comming from htc desire/bravo is wifi-data-sound toggles switching waaay faster, fluid homescreen (still to date), no restarts, excellent screen with great pixel density (although is TFT).... it's a great phone overall, especially given the price tag...
haven't played much games so no comment on that. battery with average usage lasts 2 days. but it can go as long as 3 days. yes, charged it tonight after 3 days of usage which would leave me with desire's battery on 10% the next morning (24 -ish hours). really impressed with that...:good::good:
my only negative comment (the thing doesn't bother me that much, but here you go) is that the touchscreen sometimes feels unresponsive, or not very precise. sometimes pinch to zoom doesn't register and hitting some small on-screen buttons require more tries. but as i said it occurs rare enough not to bother me much...
hope this helps...
I would make a CWM and Rom for it ... but there should be around 15 people which would like a rom on this device ...
well, I've seen some people in croatian forums that might be very happy if you do...
but, what about custom recovery? I think that there isn't one yet...

To the guy that broke his phone:
What are you dealing with is a soft-brick. In short, You are f***ed. If your recovery is stock , that's even worse. I bricked my Grand X Pro like that, and lied to the retailer that an update broke it. Now it's fixed. Try lying to the retailer , in my case it worked

I have found a friend with Grand X Pro , i made a ROM Dump and so I sucessfully made a MIUI Port for Grand X Pro
He will be away for 4 Months so he cannot give me more files which i will need. I will share the ROM in about 4-5 Days . The ROM is MIUI v5. The installation fully works (tested with kitchens - no fails) , now i only need to make a CWM to get this Rom installed. Here is the ROM which i used as base: Click here.I added fully root permission , swap support and OC support added (no sure if it works , u gotta test it. It was a work like hell so please don't care about if there are any little bugs :good
I have decompiled the stock recovery.img (thanks to kudzo) , and took the files that i need to make an CWM Port.
The CWM is finished , now i only need some people who can test it.
Click here to download my CWM Port.
This CWM port is only made for ZTE Grand X Pro.
If you get into a bootloop , just fastboot stock recovery.img Click here to download stock recovery Just name it to recovery.img and fastboot it.
How to fastboot the CWM recovery.img
1. download ZTE USB drivers
2. download and install Android SDK tools and platform-tools to get adb and fastboot
3. download recovery.img recovery image
4. create a new directory somewhere and copy adb.exe, fastboot.exe and recovery-cwm6032-atlas40.img into it
5. plug in your device via USB cable and install drivers (make sure you've enabled USB debugging on your device)
6. cd into the directory you created and execute following commands in terminal window
adb reboot bootloader
fastboot flash recovery recovery-cwm6032-atlas40.img
fastboot reboot
8. Boot into Clockworkmod by pressing volume down while powering on or using the command 'adb reboot recovery'
I really hope that CWM works

Bricked Tablet (Swapper2)
Hello everybody...
So today I was trying to enable SWAP on my Tegra Note and, after some success (except I couldn't get it to activate on boot time) I found, here on XDA, a topic mentioning Swapper2 (I believe that if I have read a little further I may had found the problem this app can be).
I installed and configured the app (to put swap at, if I remember right, mmcblk0p3). I really am not sure if this was the partition I pointed the app to. But upon searching 'rootjunky.com' I found information that says this partition is the BOOT one.
To finalize it... My Tegra Note is stuck at the "Tegra Note" logo (rebooting constantly), I can enter bootloader, the device is recognized via fastboot but I can't enter recovery.
I already flashed everything back with Super Tools, but nothing changed since now.
Hope you guys can help me solve that problem, so I won't need to use my tablet as paper weight.
Thanks in advance.

So today I was trying to enable SWAP on my Tegra Note and, after some success (except I couldn't get it to activate on boot time) I found, here on XDA, a topic mentioning Swapper2 (I believe that if I have read a little further I may had found the problem this app can be).
I installed and configured the app (to put swap at, if I remember right, mmcblk0p3). I really am not sure if this was the partition I pointed the app to. But upon searching 'rootjunky.com' I found information that says this partition is the BOOT one.
To finalize it... My Tegra Note is stuck at the "Tegra Note" logo (rebooting constantly), I can enter bootloader, the device is recognized via fastboot but I can't enter recovery.
I already flashed everything back with Super Tools, but nothing changed since now.
Hope you guys can help me solve that problem, so I won't need to use my tablet as paper weight.
Thanks in advance.

Nevermind guys...
Found the solution on Advent website (as a new user, I can't post links to the tool, sorry). :victory:
I have used supertool 2.5 and unlock my bootloader but i lost data connection and lte on my device after flashing 4.4.2. Everything is working fine except data connection. Even the lte option is missing on the settings. Any suggestions?
I was able to solve the issue by flashing a etuline brand tegra note 7 LTE version. Got my lte back. It has issues though.
Just a reminder guys. Don't flash evga supertool on LTE version. You'll lose LTE

OnePlus just hard-bricked my device and don't give a ____.

Hello xda members, yes you heard right, OnePlus bricked my device, did you had a problem with the OnePlus support too?
Here's a sum up what happened:
> I buyed the one in january 2015
> batterylife on Cyanogen OS was terrible, so I switched like many other users to custom roms
> the batterylife was better, but not good not bad, normal
> many users are saying that Oxygen OS has amazing battery life
> so i searched and found out that there isn't an official flashable version, i found out that the support flash it by every user manually with a remote session
> so i contacted the support, made a meeting
> the support was nice, but then...
> 12pm (est) on monday 28.03.16
> the remote session started, there standed that it will get recorded on my windows vista pc(does anyone know where? i dont find it, but i have the chat between me and the tecnicer, see the attached file
> the technicer installed drivers and flashed afaik per adb, but it dont found my device, he did something with drivers and said i need to reboot my pc
> i did it
> still dont work
> my phone was ok
> so he used a chinese tool
> then he wrote he's very sorry and that my device has a hardware issue and that he will send me to their RMA/RRR(he wrote both, its afaik the devicechange support)
> I was sad looked to my phone: dead, hardbrick, idk how, he just hardbricked it, but ok its not full dead just hardbrick, its able to fix(i found athread on xda, but the problem is that my device got bricked by flashing oxygen OS, so I think I need to give my device to the support, they need to fix what they did)
>I was only sad, not angry, he did his best, so i waited for an email from the support
> I got one with my adress and they asked if its true
> it's #sotrue
> after 2 days i still didn't got an email, so i am now angry af
> many of you are thinking now 'just chill dude they are humans too and you are not the only one which need the device change support, but guys, you need to know that this guys which need the support to droped for example their device in water and want that 1+ fix it, but i didnt dropped it and didnt bricked it, so oneplus need to care about me, its their fault, but they still dont answered after 2 days, guys i need my device, they know that i am angry because they bricked my device, ok 12 hours before i get an answer is ok they are humans too, but not 2 damn days, they bricked my device, not I.
I dont wanna hate against oneplus, i just write this because i am very angry that THEY bricked my device and don't give a ****, that's not a good support!!
so please dont remove this thread admins, if something is not ok contact me i will edit it
Had you guys a problem with the support too? Write it and vote in the survey!
I'm sorry that you are unhappy with the phone.
I'm own of the same device since rough about the same date like you.
First of all I've install an own recovery menu (TRWin) and use uo from this time CM 5 / 5.1 and now 6.x
I couldn't say that I've the same problems like you. The battery life is independent of the OS and which apps are are used. At minimum the akku reached for 3 day's or more( look how much % does you display used).
In the case that I'll have your issue : boot into the recovery at make a wipe of = cache / Dalvik cache and data ( factory reset). After that reinstall your apps fresh from the market.
Also install Aps Ops to control the access of the apk's. If a Apk check every. 5 Min something of an update, the battery drains... thats normal.

Sorry bro i already tried everything, bbs(there were gservice wakelocks which cant get killed, i installed other roms there were again other wakelocks and more), elixier 2, gsam, this what you said that if a app drains every 5 minutes and more, at least the batterylife was normal. At least only 3 hours on screen time. Thats the reason why i wanted to try out oxygen os.
In this moment I use the TRWin Recovery ( wipe Cache / Dalvik / Data) ; CM 13 ( Android 6.0) and Google Apk ( not the big one / Small or medium packages) for marshmallow.
I've ~ 170 Apps on the phone - without any issues ( ok, the batteryife was a little bit better with 5.0, but that's all ( here the compare is not 100%, because more Apps : but at the beginning the phone was running around 6-7 day's)
Does the PC see something, if you connect the Phone via USB?
If yes, you can bring it back to life

Hi, yes, i already tested it, its a hardbrick and the pc detect it.

I am thinking about to fix it self, but then i wont have Oxygen OS because i think it will do again a full brick. But i need my phone on monday because i am then 3 weeks on a work placement and need my phone. :/
If your PC see an unknown Device, the phone is ot hardbricked. Its a hard Softbrick
If I remember right, you will find a link in the Oneplus forum for the needed driber. With this one, you can bring back your phone to life. A recovery menu is in a normal case enough.

Yep, if you connect the OPO to a PC is it recognized something like "Qualcomm device"? If it is, this tool is for you. Once you have the tool opened and the phone connected to the PC, press Volume up + Power, the phone should vibrate and then it should appear under Device Manager. Here's additional information of this process, found on the OPT thread:

First step, turn off drive signature enforcement in windows 8/8.1/10. Tutorial Here
Second step, hold the power key for 20 seconds to force turn off power. connect OPT to usb, hold volume+ and power until your PC finds a new hardware (if it doesn't work, try hold volume+ and volume- together)
Third step, go to device manager in your PC, find the new "QUALCOMM-HS USB Diagnostics 9006" device. Update its driver in property page using the Qualcomm driver provided (for 32bit windows, select x86 folder; for 64bit windows, select x64 folder).
Fourth step, when the driver is installed properly, run MSM8994DownloadTool.exe in the recover tools folder, using admin privileges . Clear start in top left corner and wait for it to finish.

Second note about drivers if that I had the worst time trying to get things to work on my Windows 7 computers. Both Windows 7 and 8 block unsigned driver installations. I've tried overwriting these settings and spent half a day messing with it, and I never go the next steps to work properly. I ended up trying installing the drivers from Setup.exe and the following steps on my Windows 2003 server and things worked properly first time. I am not saying that you won't get this to work on Window 7 or 8, but if you're having troubles try Windows XP, that might make a difference.
I also deactivate unsigned driver installation but still same fail... I found a Qualcomm HS-USB QDLoader 9008 2.1.0.5 for Windows 7 that I used. I opened the Device Manager, I found my device named QHSUSB_BULK with an yellow triangle. I pressed udate drivers , choose from computer and installed that Qualcomm HS-USB QDLoader 9008 2.1.0.5 I donwloaded. AFTER THAT the tool found my phone and I was manage to flash ROM took me half a day. I cant have done wrong , somethnig must be wrong with the drivers in the tool for w7 64bit or something . this was the first time I have hard bricked a phone EVER and I have flashed a lot . But im glad it worked out with that Qualcomm HS-USB QDLoader 9008 driver since that guy also had same problem as me and later got it to work with that driver. Qualcomm HS-USB Drivers

Hope this helps man. Greetings!
EDIT: just noticed I linked the same as @Hellfireworks, disregard. Hope you get it fixed up.
This tool had been out for the one plus one specifically for the longest time. I wouldn't use the one plus two tool because it is for the op two.
http://forum.xda-developers.com/showthread.php?t=2991851
I haven't had to use this myself, but others have, and the forum is full of success stories. I have however fixed my buddies one plus two via an unbrick tool, and was almost the exact same process.
This tool has the proper firmware specifically for the one plus one, hence why i recommend it over the op two tool.

A500 in 2020 ; Root, Bootloader, Custom ROM - LINKS WORKING

Greetings,
I wrote this tutorial to help all the people strugling with their A500 , to unlock the bootloader , install custom ROM and root it since I've finaly managed mine to work as I wanted it to. All the links / threads that I've posted are active and DL links are working.
Note : Below is going to be text in italic , just to show what I've been through and tried at the begining of my post , seeking for help , before I managed it to work for me at the end.
Before you start linking and re-directing me to other threads, I have read many threads on here that have instructions etc... but the problem is that 80% of the links from stock rom's , flashers , recovery's don't work because most of those links were created in 2012,2013.
What have I tried :
- rooting via ICS_rooting_A10x_A5xx thread ; couldn't get full root
- installing stock OS from Acer's website via SD card to get recovery menu back ; unsuccessful
- Acer Iconia A500 Tools by blackthund3r ; It only detects A500 in APX mode , but it says install driver's which I already have.
Currently running : ICS 4.0.3 with corrupted recovery menu and unsuccessful root
I would be very happy if anyone could help me and firstly return my A500 to full stock (full wipe via recovery menu), and from there start the procedure of rooting , unlocking bootloader etc... and supply me with working links to tools, roms and flashers. Everything step by step.
Thank you very much for help in advance.
Best regards,
Domitri from Slovenia :fingers-crossed:
Update - Bootloader ; OLD FINDING
I got to a point where I realised that my bootloader is locked. I've tried unlocking it via fastboot commands from the following thread : forum.xda-developers.com/showthread.php?t=1514951
I tried : " fastboot oem unlock" and "flashing unlock_critical" but 0 result, I ended up getting a small red text error on my tablet and I would have to start all over. I typed "fastboot oem lock" just for my interest to see what would come up and I got this , just like in the original thread : "Fastboot: Device is already locked! Abort ..."
I am going to try and unlock the bootloader via some run.bat option from APX mode ; I forgot where I found it (going through too many posts , going to post afterwards).
Note : Everything that I try, and if it work's for me, will be uploaded to my dropbox and will post a link with detailed instructions on how to do it, just bare with me please
Its hard to find working files / DL links for this tablet from other threads because everything is from 2012,2013 mostly.
START OF THE TUTORIAL
Note : Before doing anything , if you tried unlocking the bootloader and rooting and it was unsuccessful, I suggest you reinstall the OS via update.zip from SD card in recovery menu, so you have a fresh start and also install the drivers that I have provided, that way my steps and procedures will work 100%.Be sure to scroll down to the end of the thread to check for any new updates. If you have any questions or you ran upon a problem, feel free to message me or comment
MEGA LINK - ZIP FILE CONTAINING EVERYTHING YOU NEED - SEPERATE LINKS TO THE FILES ARE POSTED BELOW : https://mega.nz/file/IAIhUAzT#KNGqIG7ReTlRcuBXHwFiEcY4CAz3xZsKjzVXhhSc6MU ​Credits & big thank you for all the post's , help & files : KaijiKun , Civato , Blackthund3r , Vache , Turnert , Dibb_nz , Mlopik , Jm77 , Chainfire , Skrilax_CZ
USB drivers : https://www.dropbox.com/sh/6lx3uxwhj5zxbbm/AAAbhxcPTNSFX7Z0A3t3z93Pa?dl=0
In the drivers folder in dropbox you have 2 installers for ADB, if one doesn't work for you you can try the other one. "UniversalADBDriverSetup" worked for me.
In the folder you also have 2 APX drivers , one is from Nvidia and other is Universal Naked Driver 0.73. Universal Naked Driver worked for me.
You update the APX drivers via device manager.
optional Android Multi Tool : https://www.dropbox.com/s/s7ypank8oijwwry/Android_Multi_tool.zip?dl=0
In the MultiTool folder you can SHIFT + RIGHT CLICK and open a Powershell command window , and then write "adb devices" to check if you installed ADB drivers properly. If you did , you should see your device serial number pop up.
Make sure you have enabled USB Debugging in settings under Developer settings on your A500 !
How to bypass driver signature enforcement in Win10 : https://www.windowsreport.com/driver-signature-enforcement-windows-10/ - needed for updating the APX driver
or in other words, how to forcebly install drivers when windows doesn't allow you to install them.
STOCK OS 4.0.3 ICS : https://dropbox.com/s/djblya5kol2cp4a/A500-Stock.zip?dl=0 thanks to KaijiKun
Rename the zip to update.zip and apply update from sd card in recovery menu. If you have a corrupted recovery menu like I had, this is what you do :
Press the volume down button (the one closer to the power button to the edge)
Press the power button for 2-3 seconds and let go
Keep holding volume down button until small white text pops up in top left corner of the screen.
This procedure will also get you into recovery menu (if you have a working one)
1. BOOTLOADER
Before you start unlocking the bootloader , you will need to get your CPU ID which we later convert to SBK needed for flashing the bootloader.
I have managed to obtain CPU ID number by the following steps :
Install File Manager+ on A500 (or any other file manager) ; link to File Manager+ : play.google.com/store/apps/details?id=com.alphainventor.filemanager&hl=en
Make sure you have ticked to see hidden items in settings
Go to : System /sys/firmware/fuse/acer_cpuid and open as text with HTML Viewer (best option)
OR
With File Manager+ navigate to System /mnt/external_sd/dmesg.txt
Long press on the dmesg.txt file and share it / send it to yourself via mail
Open the file on your PC and CTRL + F (find) the word "androidboot.serialno" , that is your CPU ID.
That 15char number is your CPU ID (example : 37c7084407fb2d7) which you can convert to SBK number with SBCalc.
You should get something like this at the end : 0x16796E00 0x88991201 0x67D0F603 0xC2DD2003
Sometimes there might be a 0 infront of your CPU ID , just delete it.
Note : Copying my CPU ID / SBK will not work , every tablet has It's own unique one.
SBCalc : https://dropbox.com/s/g4ay6hfvym1jxwy/SBCalc.zip?dl=0 thanks to Vache
originaly from this thread : https://www.forum.xda-developers.com/showthread.php?t=1810618
Now when you extracted and got your CPU ID and SBK , we can start with flashing the bootloader.
Nvflash tool : https://dropbox.com/s/jecamd2w91nx3k7/A500-Bootloader-Nvflash.zip?dl=0 thanks to KaijiKun
Extract everything to a new folder on your desktop
Replace the recovery image(recovery.img) inside the nvflash folder with this one : https://dropbox.com/s/0gd9jhi8ufzhpbc/update-recovery-TWRP-rev2.0-beta4.zip?dl=0
Inside the folder you will see a HowTo text file , open it and just follow the instructions.
After you ran A501 A.bat , power off your tablet , and go to recovery mode - Volume down + power button then release power button after 3 seconds while still holding volume down. If it doesn't go directly to recovery menu by TWRP , select "BOOT RECOVERY" from the green menu
Follow the instructions from HowTo.txt to wipe the system
Power off your tablet , unplug the USB cable and put it in APX mode again. When in APX mode, reconnect the USB cable
Run A501 B.bat and enter your SBK again
When everything is completed both when runing A and B bat file you should get "PASS" written on your screen , dont mind if you get any small red text below that.
2. INSTALLING CUSTOM ROM
Now after we unlocked our bootloader and installed TWRP custom recovery, It's time to install our CUSTOM OS / ROM.
https://forum.xda-developers.com/iconia-a500/general/2018-a500-upgrade-threaddownloads-to-t3832293 thanks to Turnert for the post and Thor2002ro for the ROMs
In this thread linked above you cant find 4 different ROMs , for me every single one booted, but I couldnt get gApps (Google Play and Google Play Services) to work with any of them , Google Play surely will open, but when you will try to download anything it will pop up an error.
If gApps dont work on custom ROM , you can still download and install APK's from the browser and use them normaly.
The only ROM that worked for me the best and most stable with working gApps is Tegraowners 4.4.4 : https://www.dropbox.com/sh/lv2u88kjnzajcb5/AACW8iKYARd-zHgK9_w4DDgCa?dl=0
In the link above you will find both the ROM and working gApps.
You download the rar file of your chosen ROM
Copy the zip file / files to your SD card
Boot your tablet into recovery mode. From the recovery menu hit Install and then navigate to external_sd folder.
Click on the zip file in the folder / SD card and swipe to begin installation
Go through installation
After the installation of the ROM , install / flash gApps
READ THE TUTORIAL BELOW ABOUT FLASHING ROOT - SUPER SU BEFORE EXITING RECOVERY
If the installation of the 3 things was successful you should boot into your custom OS
Note : The first startup always takes alot longer - several minutes , after the first boot, the booting time will be alot faster
3. ROOT - FOR CUSTOM ROM
Download SuperSU version 2.82 from the following link : https://download.chainfire.eu/1220/SuperSU/ thanks to Chainfire
Install it in TWRP custom recovery after you've installed your custom ROM and gApps.
4. ROOT - FOR 4.0.3 ICS USERS ONLY
Blackthund3r tools : dropbox.com/s/58g5v2x0lwg8mab/Acer Iconia A500 Tools by blackthund3r.rar? thanks to Blackthund3r
I have somehow managed to root my A500 with ICS Root 7.2.0 tool , altho it was saying in bottom left corner that there is no A500 connected with debugging. I went and give'd it a shot without knowing it's gonna work , and my tablet restarted and I was suprised, checked root with 3 checkers, and looks like it is done.
Leave everything as it is ticked , only the last 2 items should be unticked - "Disable AcerNidus" and "Don't reboot after installation"
Note : Even if your tool says "No A500 with USB Debugging Detected!" , ignore that and hit "DO IT" button, it works anyway !
If your root was successful , your tablet should reboot about 2-3min after hitting "DO IT" button and instead of "DO IT" you should see "DONE"
Check your root with Root Checker Basic : https://play.google.com/store/apps/details?id=com.joeykrim.rootcheck
Because there is a older version of SuperSU installed, and you cannot update the binary when you open up the app on A500 , you need to download and install a newer version by yourself.
SuperSU 2.82 https://androidapksfree.com/supersu/eu-chainfire-supersu/ thanks to Chainfire
Download the APK from your browser on A500 , and install it. You will be prompted that this will replace an existing app - hit ok.
Note : Be sure you have ticked "Unknown sources" in settings under security tab !
When you have installed the APK, open it up. It will prompt you "The SU binary needs to be updated. Continue?" ,hit continue and choose "Normal" installation of the binary.
I hope I helped you with this tutorial, but if it happens that you're stuck somewhere, just send me a private message and I will be happy to solve the problem with you.
UPDATES
22.3.2020
I noticed after using my tablet on IconiaHD ROM that gApps stopped working , and I'm getting error at all times that google play services stoped working and it's annoying because you can't use your screen at all because it's poping up all the damm time.
I tried and flashed my A500 with this ROM - https://forum.xda-developers.com/showthread.php?t=1520299 Lightspeed 4.8 The download link for the zip file from google drive is still working, so there shouldn't be any problems with downloading the rom.
Next thing I did, I read that it works best with custom kernel from @ezterry from the following link - https://forum.xda-developers.com/showthread.php?t=1703590 (download link still working inside the thread - ezT20-v1.0.1-a500_S.zip ! )
With this kernel you can overclock your tablet to work smooth , I'd say min and max value to 1408mhz or 1504mhz. Flash your tablet with kernel from your SD card after instaling Lightspeed 4.8 ROM.
I've also read that for all the outdated apps in google play, there is a little trick with the following app - https://www.dropbox.com/s/4t29ux4h20u60do/market-helper-2.0.4.apk?dl=0
It's called market helper and what it does, It shows your A500 to google play like Samsung Galaxy S8 or something similar which can run most of the apps on the market , and with that you shouldnt have any problems with ICS being too old for some apps.
25.3.2020
I've been testing all the ROMs I managed to find for A500, and the one working the best, being the most stable and having useful / non-crashing gApps is Tegraowners 4.4.4.
ROM and gApps : https://www.dropbox.com/sh/lv2u88kjnzajcb5/AACW8iKYARd-zHgK9_w4DDgCa?dl=0
Flash the 2 items from the folder with procedure I have written above in the tutorial section. I also updated the tutorial and replaced old download links with working rom link. THERE IS NO NEED TO FLASH AFTERWARDS WITH EZTERRY'S ROM !
The ROM is working perfectly when overclocked to 1504mhz settings. No need to be afraid that you will burn your tablet CPU, I have tested it , and I've also read in other threads that some users OC to 1646mhz. When OC'ed its very fast, snappy , no lag or anything.
If I will experience any problems with this ROM I will post about it / post a fix if I will find any.
Note : The market helper apk from previous (upper) update is showing up in Google Play devices when you set it up, but it isn't installing apps when you select install , so that a no go
27.3.2020
A way to stop Google Play Store from getting auto-updated / corrupt. When you download a newer app that might be downloadable to the tablet , it auto updates Google Play Store to the newest one in the background because the app itself needs those requirements so it can run. When it updates, it's corrupted because it doesn't match with gApps (services) version number.
If your Google Play Store updated already by itself, go to : Settings > Apps > Downloaded (first thing that will open) > Google Play Store > Uninstall Updates and Replace with factory version
Turn off your wifi
Open up terminal emulator
In the terminal type :
Su (then grant access if asked by SuperSU)
Type in : touch /data/app/com.android.vending-1.apk
After that type in : chattr +i /data/app/com.android.vending-1.apk
That should prevent Google Play Store from auto updating and being unuseful
I've also found a link for Chromium , optimized for Tegra devices (which A500 is) : https://forum.xda-developers.com/ga...t/app-chromium-m56-optimized-tegra-2-t3550210
When you will install everything, turn off auto updates in google play, because if you update the GPS app , after the update you will be getting an error every second on the screen saying "GPS is not responding / has stopped working" , and tablet will be pretty much unusable.
FOR ALL THE QUESTIONS DON'T HESITATE TO MESSAGE ME VIA PRIVATE MESSAGE OR LEAVE A COMMENT UNDER THIS THREAD , I WILL BE MORE THAN HAPPY TO HELP YOU !
I am struggling for days trying to root/update a500 with 4.03 installed. I am going through the same pain as you had with so many dead ends. I will try your recommendations in your tutorial in the next few days. Hoping it will work for me too.

Hey,
thanks for commenting ! I had waaay to many dead ends, but finally managed to get it working as I want to. Just follow my steps and you should be OK , if you need any help feel free to comment again or send me a private message
Everything worked perfectly fine. My a500 is finally rooted and running a custom rom. Your instructions were so clear and easy to follow. I can't thank you enough for this tutorial and all software/drivers/tools that you provided. I spent days trying to find working links for some of those tools.
Domi, hats off to you.

Greetings !
Im glad I was able to help you with my tutorial. Yeah at first I was looking like crazy around for drivers and working tools , and when I figured out its not easy to find all this stuff, I decided to put up a tutorial and upload everything to my dropbox, which will always be available to download.
Best regards,
Domitri
You can use magisk with the a500.
The only stipulation is that it cannot flash the boot image and you have to manually patch it (via the magisk app itself) and flash it via computer (there doesnt seem to be any on device flasher that ive found. flashify and flashfire do not work). It's a good idea to have the rom's boot image on your device so that you can easily patch in magisk when there's an update, and the patched file should be in the Downloads folder.

Hey ! Have you installed all the drivers that I provided in my tutorial ? They are key for the whole tutorial to be working properly. Sometimes in apx mode, my PC also doesn't recognize the device, but you must keep proceeding with steps , because they will work. Dont mind your windows not recognizing your tablet, it will do that 70% of the time.

For Spotify I think you just have to install an older version. Probably at least a year back.

Most apps don't work because this tablet does not support something called neon I don't know exactly what it is but it seems to cause a lot of the combatiblity problems with this tablet also the tablet is 9 years old so you just kind of have to expect things not to work.

Search on www.apkmirror.com for Spotify or just type into google Spotify apk 4.4.4 and I'm sure you'll find it

That's wierd, most of my apps work normally and I didn't change anything special. I just dont update the GPS app because it ****s it up afterwards and you'll be getting error messages about GPS not responding / stopped working like every second.
just passing by and want to thank you for this great post.
I had an idea, it would be nice to list the apk version numbers that works on our tablets, i mean Spotify version number 4.4.4 and so on with another ones.
Again, thank you !!!!
Hello !!

Thanks for the compliment. Basicly there is no need to do that since everyone needs differend apps and its very easy to find it on apkmirror's site , I belive that it is compatible from 4.0 to 5.0 my guess, but the best way is to stick with 4.4.4 versions of APKs.
