Linux on the Droid 2

Skrulladams figured out a way to get Linux onto the Droid X, Droid 2 / Global, Droid Pro, and DEFY (Really any modern motoblur phone with a locked bootloader.) Supposedly the Atrix has it as well? Technically, according to wikipedia, motoblurexists on the CLIQ/DEXT, Backflip, Devour, Flipout, Charm, and Flipside as well. I can't tell you whether or not this method works for those phones, maybe somebody could verify. While I was researching methods to get this all to work I found different methods for the original Droid, I am assuming that the version of blur on any phone from the OG droid/milestone is different, because the installation method seems somewhat less locked-down.
First you will need a Linux image. I suggest getting yours from Ruan over at androidclone.com
Ubuntu Laika-Beta1.2a.rar
The commands have to be issued from Linux or a virtual machine of Linux as far as I know. I downloaded VirtualBox and used a copy of Ubuntu 10.10 that I had laying around. You could use the image you downloaded above with VirtualBox. PuTTYcyg seems like a better alternative, but I haven't used it.
When setting up your linux virtual machine you might want to make your username "noob" like I did, it will allow you to copy and paste my commands.
The first thing you will need is the android sdk.
Click here to get it
Using and installing it is a little confusing. I just extracted it to my desktop.
You will have to run /tools/android, I did this by dragging and dropping the icon into a terminal window and hitting enter. You have to install the platform-tools. ADB will be downloaded to the platform-tools folder inside the SDK folder.
VirtualBox allows you to capture a USB device inside your virtual machine inside the menu. Devices -> Motorola ####
Inside your virtual machine you will need to copy ubuntu.img from the Laika-Beta1.2a.rar you donloaded earlier to your home directory. While still in the home directory create a new folder simply called "ubuntu."
Your phone has to be rooted and you need a terminal emulator. Most custom ROMs have this by default, but there are many options.
Next, open up a terminal emulator on your phone and execute some commands:
Code:
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
mkdir /data/local/mnt
Back on your virtual machine in a terminal:
Code:
sudo losetup /dev/loop0 /home/noob/ubuntu.img
sudo mount -t ext2 /dev/loop0 /home/noob/ubuntu
Dirty_Jerz has an alternate method, Click here for his thread. so it is now up to you whether you'd have everything on your internal storage or SD card. My method uses the internal storage, his uses the SD card. If you'd rather use his, stop here.
Here you will want to remove a symbolic link in /home/noob/ubuntu/usr/bin that screws this method. You can do this by:
Code:
sudo rm /home/noob/ubuntu/usr/bin/X11
Then I remove security stuff:
Code:
sudo chmod 777 /home/noob/ubuntu
sudo '/home/noob/Desktop/android-sdk-linux_x86/platform-tools/adb' shell
chmod 777 /data/local/mnt
exit
sudo '/home/noob/Desktop/android-sdk-linux_x86/platform-tools/adb' push /home/noob/ubuntu /data/local/mnt
This is going to take about 2 and a half hours so I suggest you find something else to do while it copies over.
When it's all done you will need to copy a script over in order to chroot (boot from inside android) into Ubuntu.
Download this script! (specific for this install method!)
Username: androidclone.com
Password: androidclone.com
Click to expand...
Click to collapse
This script belongs in /system/bin so you will have to put it there. The easiest way to do that would be to copy it to your sdcard and then use your terminal emulator to move it.
Code:
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
cd /sdcard
cp bootubuntu /system/bin
cd /system/bin
chmod 777 bootubuntu
Now you can boot into Ubuntu from any directory as long as your terminal emulator has superuser.
Code:
su
bootubuntu
Once inside there are some commands that need to be run in order to get a functional UI.
I got these from this site He seems to have a lot of extra configuration instructions which may or may not help you.
Code:
mount -t devpts devpts /dev/pts
mount -t proc proc /proc
mount -t sysfs sysfs /sys
-Xvnc commands-
Code:
export DISPLAY=localhost:0.0
Xvnc -localhost -geometry 854x480 -depth 24 -deferupdate 0
-start your gui-
Code:
startlxde
I prefer xfce though, personally.
--------problems----------
"/bin/sh can't access tty: job control turned off" upon chrooting
Terminal emulators from within the UI don't work.
*DRIVERS*
Touch screen support/UI enhancements for touch screen.
androidVNC
Might not be an ideal solution. I still noticed what seemed to be some graphical lag. There could be a setting that can get it running better, but an app optimized for high speed localhost operation
Chrooting a prebuild image causes all kinds of problems because the proper post-installation scripts are not run. Some programs ignore these errors, and for others they error out. I have yet to find a good solution for this but I have found hints:
Check out this page
Seems a little outdated, but maybe somebody will find a way to make a method like this work.
What we really seem to need is a custom kernel/ROM/distro team that can work on these issues.
-----other alternatives?-------
First I tried kubuntu mobile. It was very buggy so I gave up on it.
Ubuntu netbook edition has been slammed by some for being bloated, but it's ARM port should be lightweight. From screenshots it looks like it has a great UI. The problem is getting gnome to start, it encounters some error and doesn't load.
fedora has a mobile edition that looked good, I think they are somehow involved with Meego which now seems doomed. I'm not sure how similar to android it is or if it is worth the effort.
Check this out
Many of you may already know about the QEMU for android app, but we should be able to cross-compile it to use within our chroot.
I looked into wine, it should be a dead-end since we aren't on x86 architecture and it doesn't do any emulation.
VMware will be releasing a version for android.
Also while playing around I thought about porting iOS on to an android phone. It should be possible.

This could potentialy be used to get truly custom ROMs on the D2/DX/Motoblur ridden phones. Honeycomb here I come!

Sir, if you could use this to port newer versions of android and other operating systems such as meego and maybe even webos, you are truly the savior of our locked phones :O
Sent from my BLAZING FAST Droid 2 Global using the XDA app

From my understanding (not a coder or even a regular linux user), a chroot environment is just running an OS within your OS. Meego (maybe I'm thinking of Maemo?) should definitely be possible, I think there is an ARM build somewhere. Fedora was involved with them in some way, and I think might have an ARM build of one of their older releases.
Truly custom ROMs? Not sure, maybe Linux on the phone will be of help to devs?
I was hoping maybe Droid 2 bootstrapper could be modified to fastboot into the install. That still wouldn't be a true bootloader unlock and we still have drivers to worry about and might not even be possible, just an idea.

Well, we might be able to hijack to boot to maybe run CyanogenMod(at last!) . I can for sure, that would rule. I used CM on my old phone(the ultra moddable Droid Eris(HTC FTW!)), and it was the greatest rom I've ever seen

It is possible to port it to Milestone 2?
Sent from my T-Mobile G1 using Tapatalk

This is a sweet little tutorial that I've been following and I'm excited to get Ubuntu up and running... if I do get it up and running. Problematic mentions a problem where '/bin/sh can't access tty; job control turned off' and I also hit this. I'm pretty new too linux, I've only really got into it upon the purchase and rooting of my Droid 2 and I haven't been able to find anything that can help me fix this problem. Has anyone else gotten past this and had ubuntu running on the Droid 2? Or could someone point me in the right direction? Any help is appreciated.

Can u mirror Ubuntu Laika-Beta1.2a ?. I can't download at filefactory now. Or can I use another ubuntu image ?

Can someone answer? Is it possible to run it on Milestone 2?

Should be. There shouldn't be enough differences between the two for this to not work. I have a hard time thinking of a scenario where this wouldn't work for an andrioid phone. I think the main requirement is having a fairly recent version of busybox installed.

You can use any armel image of Linux. Currently I think this mainly applies to Ubuntu, there should be ARM builds for other distros out there, but these are tough to find. A skilled enough developer should be able to port any distro they wish.

This seems to be a bug from chrooting a preinstall image without any kind of real setup. I found you can do a lot of this manually, (If you're interested try googling the MAKEDEV command, I think that generated ttys for me.) but I'm still searching for a real solution. Currently I'm considering trying the debootstrap method, the "ubuntu-netbook-10.10-preinstalled-netbook-armel+omap.img" image could be the ticket as well.

thanks, i'll try with Ubuntu-Netbook 10.10

Please Help
hello i am trying this and am getting hung up on the

Can't get ADB Root Access in certain ROMs?

I've noticed with a lot of CM10-based ROM's (possibly even others), I am unable to get root ADB access.
On the ROM's that have it, I set the Root access to Apps and ADB

I can reboot, fix permissions, clear caches, but no matter what, Android Commander is never able to get Root access
This isn't the case on some ROM's I've tried though. Android Commander is able to get Root access just fine without me needing to do anything.
To name some ROM's that I can't get Root access with:
CyanogenMod 10 Nightly (9/4)
AndroidME CM10 N7 1.0.0
As for what ROM's had working Root access, I can't exactly recall correctly :/ But I think these had it working:
Codename Android 3.4.1
Team EOS 3 *JELLYBEAN* Nightlies (confirmed working ADB root)
Is there something else I should possibly be doing to get Root access on CM10-based ROM's?

Boot a unsigned kernel then ./adb remount
PS: it is effective until you reboot

"The Root access : No" because you'r using the rom which have a "secured adb" (even when you'r rooted)
Download the "adbd insecure" in this thread and "Enable insecure adbd", you can get "Root access: OK" in any rom
http://forum.xda-developers.com/show....php?t=1687590

adb root
The real reason behind adb root or insecure adb is the adb daemon in the device running at root permissions. In pre-Android 4.1 versions, this is usually decided by some initialisation script(like init.rc) at boot time. The script checks for value in default.prop,local.propand other environment variables.
If it finds build.prop,default.prop or local.prop property file with ro.secure=0 adbd is allowed to run as root. You'll get adb root and hence will be able to do commands like adb remount,adb root and adb shell's prompt'll be # by default. The user may be displayed as [email protected] or [email protected] adb GUIs like Android Commander and QtADB will get to work in Root mode.
But,if it's ro.secure=1, adb daemon is made to work in secure mode, and adb won't change to root mode on issuing adb root command. However, if su binary is present in $PATH, u can still call su command from adb shell. But, it's not enough for Android Commander to get Root Access. It is possible to attain adb root through any one of the following methods:
1.For CyanoGenMod based ROMs there is an option in Settings->Developer Settings->Root access to control root access. Choose ADB only or Apps and ADB in options to get adb root.
2.Else use adbd Insecure app by chainfire if you have a rooted device. This is useful, especially for Android 4.1+ devices.
3.Or, you may manually edit default.prop to set it's value to 0, but original default.prop will be restored from boot partition everytime you reboot(this is the reason why adb Insecure cannot permanently do adb root, though there is an option to repeat the rooting procedure everytime the device boots). This method is called temporary adb root. On pre-Android 4.0 ROMs default.prop file was located in / directory. I read that from Android 4.x this file is in ramdisk and so more difficult to edit. But Android 4.0 has local.prop which is easier to modify than default.prop( See method 5)
4.For permanent adb root, you'll have to extract boot.img, change default.prop, repack and then flash it back to device.
5. In Android 4.0 there's local.prop file in /data partition. Setting ro.secure=0 in this file will do adb root permanently. Else you can set another property ro.kernel.qemu=1 in the same file. But, this value makes the system think that it is running in an android emulator. Many exploits and root methods set this property temporarily to gain root. But, it may cause side effects if used permanently. Setting ro.secure=0 is recommended. Do this command in terminal app or adb shell:
echo ro.secure=0 >/data/local.prop
or you can manually copy a local.prop file with ro.secure=0 as it's content to /data.
6.Note that method 3,4 and 5 won't work in Android 4.0 Jelly Bean onwards. According to Dan Rosenburg(drjbliss in XDA),the researcher who discovered adb root emulator exploit and many other exploits, Jelly Bean doesn't parse any property files to set the ownership of adb daemon. The stock adbd will have to be replaced with an insecure one to gain adb root. But still,as adbd is located in /sbin whose contents are reloaded everytime on reboot from boot.img, it won't be permanent.
7. For permanent adb root, you may flash an insecure boot.img(one that contains and insecure adbd)
8. If you're really desperate and can't get adb root to work with any of the above methods use an exploit. Most of the adb based rooting methods utilise some exploit to make the adb daemon run as root. By studying the exploit and implementing it you could gain adb root atleast temporarily.I'm not recommending this method but as a last resort you could try them.
Acknowledgements: Thanks to Dan Rosenberg for explaining the reasons behind adb root, especially the one in Jelly Bean.

get root access with root commander
Question to that fantastic answer above.http://forum.xda-developers.com/images/smilies/good.gif
How do I push back my modified build.prop?
I have HDC S3 Ex v2 hung in bootloop, after changing vm heapsize to 60 from 64.(Tried 128 but it didn´t stick, so tried this and it unfortunately worked)
I have managed to start in recovery mode even though it´s chinese there, don´t understand, I can communicate through Android commander to pull the files but cannot push them back due to no "root access".
I installed the "insecure ADB" via Commander but it does no good when I can´t load android.
I have no backup. It is rooted Android 4.1.2 by Fastcardtech. has busybox installed

Use su in adb shell
Use adb shell and elevate to root access by using su
Code:
su
.
Now, if you get # prompt instead of $ sign you have root on adb shell. But, still you don't have adb root. So, don't try to push the files or use Android Commander. Instead we use shell commands to do the same.
First Remount /system partition as writeable.
i.To do this first type
Code:
mount
and find out system's device name and file system from the list. In case of my device (and many Stock ICS devices) this device name would be /dev/block/mtdblock?. ? varies for each device. I had /system as mtdblock8 with ext3 file system.
ii. Now type the following command
Code:
mount -o remount,rw -t <filesys> /dev/block/mtdblock? /system
use the number you have for '?' and the filesystem for <filesys>.
Now Copy the modified file to some readable location on the device, say /sdcard or /data/local/tmp. Then copy the build.prop to /system using cat command
Code:
cat /sdcard/build.prop > /system/build.prop
Hope it works!

Closer...

Thank you! But...
After more than one hour installing android-sdk, I got the # ( I thought the shell through android-commander was the same first)
but it says Read only file system
Another thread suggested "remount rw" before pushing but thats not something adb shell recognices "not found".
Am I only missing the adress of my device when trying remount?
Any suggestions?

Renount /system as rw
Oh, i forgot! You've to remount /system as Read Write. I've edited the above post to include that.
You need not have installed the whole Android SDK(unless you develop for Android). It's the same adb that Android Commander or QtADB uses. You can even use adb as a standalone tool along with the required libraries(dlls on windows). Now that you have installed the Android SDK, it doesn't matter.

Yes! Yes! Yes!

:good::good::good::victory::victory::victory:
It worked! Thank you so much! A new phone useless was really disappointing, but happy again
Set heap size back to 64. Maybe I´ll dare set it to 128 another day... The phone has horrible ram performance, hoping that would cure it.
Uninstallation of an app of 6-7 mb takes at least 45 sec. My old Blade with cyanogen does that in less than 10.
Hard part was understanding my system name /dev/block/mmcblk1p1 cause it wrote /storage/sdcard vfat after it.
I saw ext4 in other part and asssumed it was that system cause it had "ro" after it.
Thank you again. You now introduced me into some new territory. Not just flashing modded roms in recovery mode.
But I will search out one modded rom so I can overclock some.

[HOW TO] [FIX] Recover from nested emulated 0 folders

A user of my rom had this 0 folder issue.
This issue was new to me so it took a couple hours to find a solution.
Didn't find any related "How To" guides here so i thought i would share it here.
The issue is that your pc file explorer for example (Win Explorer) only sees a 0 folder while still running the latest HTC USB drivers.
Well, there is a solution to recover from this.

}
To recover from this you can try the following but you must be running the latest htc drivers.
Step 1
Connect your phone to your pc by USB (note: not usb3)
Backup all your sdcard content to your pc
Download this zip file and extract this to the root of your hardisk (adb.zip)
Step 2
Now open a command shell and go to your adb folder
You can open a shell by ticking "Windows start button" and type "cmd" in the search bar and hit enter.
then type the following commands in the just opened shell and hit enter after every command
cd..
cd..
cd adb
adb shell
You should now see something like "[email protected]/#"
Step 3
Now type the following commands one by one in this shell and after every command hit enter
adb shell
rm -r /data/media/0
busybox find /data/media -maxdepth 1 ! -path "/data/media" ! -path "/data/media/0" | while read filename; do mv "${filename}" /data/media/0/ ; done
Now reboot your device.
If all went fine then you just reset the 0 folder symlink and flashed a compatible recovery
If you now go to Windows Explorer then you should see your sdcard content
If the above how to didn't help the try the steps below:
Step 1
Connect your phone to your pc by USB (note: not usb3)
Backup all your sdcard content to your pc
Download this zip file and extract this to the root of your hardisk (adb.zip)
Download TWRP 2.5.0.0 recovery (recovery.img) (md5: C18DA6C73B2C7CCC9539E58C678C8DD6) and copy it to the adb folder in the root of your hardisk you just created
Step 2
Now open a command shell and go to your adb folder
You can open a shell by ticking "Windows start button" and type "cmd" in the search bar and hit enter.
then type the following commands in the just opened shell and hit enter after every command
cd..
cd..
cd adb
adb shell
You should now see something like "[email protected]/#"
Step 3
Now type the following commands one by one in this shell and after every command hit enter
adb shell
rm -r /data/media/0
busybox find /data/media -maxdepth 1 ! -path "/data/media" ! -path "/data/media/0" | while read filename; do mv "${filename}" /data/media/0/ ; done
Step 4
Now reboot into your bootloader while your phone still connected to usb.
When your bootloader recognizes your phone you should see in red "Fastboot USB"
If not then your USB drivers aren't up to date or your using USB 3
If so then type the following commands and after every command you must hit ENTER
fastboot flash recovery recovery.img
fastboot erase cache
fastboot reboot
Goodluck :fingers-crossed:

It's an issue when upgrading from 4.1.2 to 4.2.2.
User can copy files to pc prior to upgrading, then copy back after and the files can be copied to the folder visible to Windows.
Also, creating a symlink to /data/media/clockworkmod in /data/media/0/ will allow a user to get CWM to see backups and allow the user to have access to it in the folder visible to Windows.
Your solution ignores the fact the someone might prefer CWM over TWRP.

Thx for the info, didn't know that.
Strange thing is that the guy i help out didn't went from 4.1.2 to 4.2.2
He went straight from 4.2.2 custom rom to 4.2.2 custom rom.
Also i don't ignore a possible desired user recovery choice.
Issue with the 0 folder came when cwm was flashed.
Butt will amend the line .
More info is also welcome...

If you have formated your SD card (firmware update that took care of that for you) DO NOT DO THIS. apon reboot your system is no longer fucntioning and if oyu boot into recovery it does not see your SD card anymore. I had to adb sideload to get a rom back ot the phone. Not the OP fault but mine. Luckly i know how to recover just wanted to give warning to others

Bump!! I think this thread should be in the stickies @Red5 what do you think?
Sent from my HTC One using xda premium

This has only became evident to me today.
I was on stock 4.1.2 and flashed Viper Rom 4.2.2 and noticed I was missing 16GB storage.
In the thread I was told to look in data/media and all my files which I saved on SD Card from 4.1.2 were there. Also this 0 folder which had pretty much the same folders but with no user files
I was told to delete duplicate files/folders in the modia (not 0) folder but I dont know if i should just leave empty folders in Media with everything in 0, or delete all folders in Media and leaving only the 0 folder there with everything inside that intact.. If that makes sense..
I am unsure what will happen to CWM if I delete that from the Data/media folder

This has only became evident to me today.
I was on stock 4.1.2 and flashed Viper Rom 4.2.2 and noticed I was missing 16GB storage.
In the thread I was told to look in data/media and all my files which I saved on SD Card from 4.1.2 were there. Also this 0 folder which had pretty much the same folders but with no user files
I was told to delete duplicate files/folders in the modia (not 0) folder but I dont know if i should just leave empty folders in Media with everything in 0, or delete all folders in Media and leaving only the 0 folder there with everything inside that intact.. If that makes sense..
I am unsure what will happen to CWM if I delete that from the Data/media folder
Cheers

Anything that's already in /data/media/0 can be deleted from /data/media
/data/media/legacy/, /data/media/obb/, and /data/media/clockworkmod can be left alone.
If you want to be able to see your clockworkmod folder and backups when connected to a PC/MAC you'll need to create a symlink in /data/media/0 pointing to the data/media/clockworkmod folder.

Yes very annoying.
Well i formatted and reset rom and now have no SD Card, directory or files om the phone.
A guy here on xda tried for almost 2 hours last night to fix it, can sideload a rom bit still no SD and rom will not boot.
Should never have rooted this phone, i was npt going to but of course i did amyway.

Tried this method on my nexus 10 (with the proper recovery but didn't work) sucks because i don't have links to my sd card and cant download anything as a result. flashing the google stock image didnt help either wondering if there was anything else i can do?

[EXPERIMENTAL] Full ADB Root, System RW, and DM-VERITY Off for ALL G5's!!!

UPDATE Thanks to @thjubeck for testing this, it seems that this userdebug kernel actually works on all devices running antirollback v0 and running Marshmallow! I only have the Sprint variant, so be careful!!! Enjoy root guys
A bit of a disclaimer is that this is root through adb. dm-verity is off and system is rw, so you can install apps as root, get a hotspot hack to work, and anything through a shell but I am having trouble installing SuperSU. Please try yourself though as I am probably doing something wrong! If there are any bugs you have found please post them, as this phone is my backup and not my daily driver.
So okay, here is the guide:
PLEASE MAKE SURE YOU HAVE A WAY TO GO BACK INCASE THINGS GO WRONG. DO NOT ATTEMPT TO ROOT THIS WITHOUT HAVING A KDZ/TOT FOR YOUR DEVICE THAT YOU KNOW YOU CAN FLASH BACK TO. I AM NOT RESPONSIBLE FOR THINGS GOING WRONG.
Here is the fix for LGUP
1. Download this zip
2. Install Terminal Emulator from the Play Store
(This is modified from the V20 bootloader unlock, HUGE thanks to all of those devs for sharing their dirtysanta code with me and allowing me to modify it!)
3. Copy all the files from inside the "dirtysanta-boot" and paste it into your active ADB directory
4. Plug your device into the computer and verify ADB is working. Then;
On Windows, double-click "RUNMEFIRST.bat, DO NOT CLOSE THE LOG WINDOW THAT OPENS, then double-click "Step1.bat"
On Linux/MacOS ("#" Signifies a comment below)
Code:
./RUNMEFIRST.sh
# OR
bash ./RUNMEFIRST.sh
Open a Separate Terminal next to the RUNMEFIRST terminal, then type:
Code:
./Step1.sh
# OR
bash ./Step1.sh
(When you run The sh or Bat files there may be a Permission denied error on 2 files: Flatland and Flatland64. This is normal and nothing to worry about.)
5. Wait for a shell prompt, then type (or copy):
Code:
run-as con
chmod 0777 /storage/emulated/0/*
6. Open Up Terminal Emulator on your phone
Type:
Code:
id
Check if context is "Untrusted_app". If it is then we're good to go!
7. Type into Terminal Emulator:
Code:
applypatch /system/bin/atd /storage/emulated/0/dirtysanta
8. Watch the RUNMEFIRST dialog for when it tells you to run Step2 (we don't have a step 2)
9. Reboot the phone into recovery mode and wipe data again
BOOM! Now the you have a userdebug kernel running on a userdebug system Time to turn off dm-verity, otherwise you will have a red triangle on reboot (Your device is corrupt. It cannot be trusted and may not boot) and cannot edit /system.
1. Finish setting up the phone and enable USB Debugging in developer options (you should know how to do this)
2. Plug the phone into your computer, and run these commands
Code:
adb root
adb disable-verity
3. Reboot the phone
4. Run
Code:
adb root
adb shell
mount -o rw,remount,rw /system
Bam. Enjoy your FULL UNLIMITED root shell with system set to rw and dm-verity off!!! Just make sure to type "adb root" before "adb shell"
If you ever want to go back, just flash your stock TOT/KDZ with UPPERCUT and you'll be all good!

I'm using a H850, but still - thanks for your work!

Thanks for the amazing work while almost every one lose the hope .
Allow me to ask about the other versions H860 in my case .
Any chance to modified your files to make it work ?
If you need a testing phone to try figure it out Pm me .
Again thanks for this great job

I'm a Canadian H831 owner. Just wanted to post to say great work so far and if you get SuperSU or another SU app installed, enjoy the $850 bounty.

I think I also found an unlimited hotspot hack, so there's that too!

You're doing God's work, sir. :good:
I wish I had that variant... you'be renewed my hope though.
I have a Canadian H831 [Telus], how much of an undertaking is it to rejigger your method for it?

Hello, I am working on the root for the Verizon V10 and I came across this today. I was wondering how you made the userdebug.tot because I know this will work on it, Dirty Santa works up to the same point as you, so i'm wondering if I could do this and maybe even get supersu to work. Thank you

@Honestly Annoying could it be possible for you to "spoof" the firmware info and change the variant (LS992ZV4) to other locked g5 (such as the h831 h860..) so we can try to flash it via uppercut and see how much it's broken ?

Update: Now works on all devices running antirollback v0!!!!

I am not sure how to check the antirollback version on on actual phone, you would need @autoprime for that.
Antirollback is basically exactly what it sounds like: It is part of each update that disallows users to rollback to previous versions of their software. This is built off of the first version of antirollback (v0) for the G5, so it will only work on phones with that version. You can test it out yourself, as it won't do any permanent damage, but just make sure you have a working TOT/KDZ to go back on.

Change the "850" to your model number. Such as "830" for T-Mobile or "992" for Sprint

Aha! 831 Canadian variant running Marshmallow. Almost upgraded to nougat but then saw this thread thankfully, I guess I will hold off if this means it increases my chances of getting root

For those interested, I can confirm that every h831 firmware up to nougat has a rollback count of 0, and from @autoprime :
H850 and H860 are fuse 00 and Sprint ZV3/4 are fuse 00.

Anything higher than ZV4 is 01 or higher.

I don't know what I missed, but now I get Your device is corrupt. It cannot be trusted and will not boot . I'mma try to flash back my system and try it again.

P.S : I can't enter recovery or download mode ... how much I'm I screwed ? It just keeps rebooting

How to extract your boot.img from any rom (adb)

If there is any trouble, leave it in the comments, i'll respond
I am not responsible if this crashes, bricks, causes nuclear warfare, or anything else that may happen, I'll try to fix it if you put your problem in the comments
Extract boot.img using a few simple adb commands
Hi XDA, I want to educate you on how to extract your boot.img using adb. Since systemless root and kernels all utilize the boot.img, undoing these changes consist of just flashing the boot.img in TWRP!
I pulled this from a RootJunky video and it worked on my pixel xl on any rom
Prerequisites:
You have to use TWRP (img or install, depending on the method)
Locating the boot.img
There are many tools used for this, I just like using the logs of an installer
Flash the TWRP installer and read the logs
It says "found boot image in *path*" (Usually /dev/block/sda19 or sda20)
If you want confirmation, flash magisk and it should say where your boot.img is
Extraction of the boot.img (2 ways)
Without TWRP installed
fastboot boot twrp.img
Open a terminal (on a computer) and type adb shell
your window should have only a ~#
Type this command in
HTML:
dd if=**boot.img path** of=/sdcard/boot.img
Replace the **boot.img path** with whatever path you found your boot.img in when locating it
This should pull the boot.img to your /sdcard (storage) directory
To transfer to computer, just use your favorite file transfer method!
With TWRP installed
Install TWRP
Reboot to TWRP
Follow the steps listed in the without TWRP installed category
I would like to thank RootJunky for this method, it works flawlessly

There is a method to extract boot.img without TWRP? The tablet that I own doesn't have a any developed custom recovery, is an unsupported low-end device. Thank you for your help.

Very useful guide. No, it's absolutely useless and of no help. THERE IS ZERO NEED TO EXTRACT THE BOOT.IMG IF YOU HAVE ROOT. You NEED THE BOOT.IMG TO ROOT (VIA MAGISK).. If someone has TWRP, just fkn flash magisk right then and there. Rootjunky is useless.

Agreed, this is useless. I need the boot.img so that I can patch it with Magisk and then flash onto device. If I have TWRP, I don't need the boot.img.

i disagree, having the boot image is usefull if you want to modify it

Likewise, I have to agree...this primer IS useful as being able to extract a boot.img file from a stock rom is imperative for a lot of users with off-brand or rebranded MTK devices. For instance, I have a Blu G80 and there is virtually no dev support for this device and I would personally like to be able to root from the latest (or any) stock ROM or heck, repartition into the new A/B format to absolve myself of OTA updates forever.

Doogee N30: I do not have root, there is no recovery or rom for my phone, Can I extract the boot.img from my phone storage, to patch it with Magisk? Maybe with adb? Idk, please help me, I'm dying here....

This should also help:
Just boot into TWRP and run the following:
Code:
find /dev/block/platform -type d -name by-name
then use
Code:
ls -la /the/path/displayed/from/find
Then make note of your boot partition, so everything after the arrow ( -> ). If you are using a slotted device, it shouldn't matter which boot slot you pull, but it might help to pull the the boot slot you are actually using.
Then, as stated in the OP
Code:
dd if=/boot/img/path of=/sdcard/boot.img
Src:
adb find phone partitions
I need the command to find the partition of all Android devices For example, on some Samsung phones, you can use the following command to partition the device adb shell ls -al /dev/block/platform/
stackoverflow.com
I just installed Magisk on my OG Pixel. Using the method above, it took me a matter of minutes. I booted into TWRP to do this in adb with root.
EDIT:
I found a more workable solution, as long as you have the "find" command in TWRP or some other ADB session.
This definitely doesn't work if you don't have root in adb. TWRP or equivalent environment is required. If you don't have TWRP for you device, then at a minimum you need some way to root the device. Once you get root, then you can startup ADB, type "su" or other SuperUser command, and then run the "dd" command above (the 3rd code block). Without root, the "dd" command will fail - permission denied.
I've tried this on a Nexus 6P and an OG Pixel so far.

Hello everyone i need help somebody can't u helpme i can't find the bot.img in My device storage i have the SKY elitte p55 i try i'n the websites any guide but no found nothing thanks for helps

after magisk done patching , reboot to bootloader
fastboot flash boot magisk-patched.img
now u have magisk on your phone
just sharing what is done on my phone . now pixel experience plus latest on my mojito/sunny device has root

I have Chinese Android TV Boxes like below links, please which TWRP image should I use?
The TWRP site seems to be all oriented about phone recovery images.
The TV boxes appear to be AMLogic ?CPU?
Is there a tutorial that shows ideally with a phone storage diagram the concept for flash vs. backup vs recovery?
Some say you can boot from an external recovery image with fastboot without writing it on the device?
(video is a bit old from 2015)
My current understanding is the "stock recovery partition" does not offer enough functionality to read/write the various partitions (boot,recovery,system,vendor,???) So is that what TWRP recovcery images provide? It does NOT appear they offer a "generic" recovery image.
If I manage to read these partitions can I edit their filesystem content on the PC? if so with which tool? are they standard .zip/rar/tar/iso files?
Currently I am running adb command over WiFi, these boxes come with 2 USB ports and sdcard slot. Can I use USB-A to USB-A cable to connect this boxes to PC, like the phone junkies do?
I don't have the equivalent of pressing volume/power buttons like on phones to boot into recovery or standard, what's the best way of doing that, fastboot/adb/an app on the tvbox?
These boxes already have su when I enter adb shell, su, whoami >displays> root, so that means they are unlocked.
I am bit lost in all of this, otherwise I won't be here. Thank you so much!!!

I tried to follow the info and steps in a video by rootjunky and apply to a chinese tv box however I am not finding the boot/recovery/system/vendor partitions I ?think? I need to back up in order to flash onto another identical box (ie. replicate the various manual setups I did of app launcher, de-installed stock apps, my apk installs, etc...)
According to the below commands and output could you please let me know what pull commands I need to issue to copy the necessary sections onto my PC, thank you so much.
Here is my current wild guess to achieve my backup and replicate goals.
Here are the peek around commands and outputs...
adb -s 192.168.1.120:5555 shell "ls -R /dev/block/platform | grep by-name"
Some output is empty ??? in particular msm_partitions.txt ?
adb -s 192.168.1.120:5555 shell "ls -la /dev/block/platform/soc/fe08c000.mmc/by-name/"
if you need any particular output (eg. adb, or AIDA64, ...) just let me know and I will post.
Video reference...

false. any rom does not have twrp capabilities, like, for example the phone Alcatel 3 2019. You should change the post's title.
In those cases that no twrp is available it is impossible to extract the boot.img afaik.

I know I'm a little late to the party here, but maybe I can provide some insight into this. For starters, until you can mount /system rw properly, ADB just aint gonna work like you want. I have one of these 905w2 boxes (oppen x88plus..) and have been dealing with this for a minute now. If you at least have wireless adb access, you can:
A) get fastboot access
B) get adb sideload access from stock recovery
..and thats about it. You use the right hand USB port. Interestingly, my win11 chimes when I plug in my box when its booted normally, however nothing appears in device manager or usbdevview.
In closing, why dont you just DD the partitions to sd\usb storage? IE:
dd if=/dev/block/by-name/boot_a of=/sdcard/boot_a.img
