On my G2 i used a similar method when lollipop leaked and I had to do it several times till it finally took.

But you could be missing something obvious too. I took the various steps and put them in a number word pad doc and used that to follow and copy/paste.

Did you use the second port from the portsbat list? Miss any step?

[G4 Q&A, Help & Troubleshooting] darkvoxels:
How does this method work?

Hello XDA, this is my first official post and am interested in helping the community. I have the t-mobile g4 and have successfully flashed the root image. I understand that the LOCKED bootloader verifies the signed boot sources such as the Recovery, LAF etc.. I read the the system image is to large to be verified this way so the kernel uses dm-verity to verify the system as its loaded and run. So I have a disconnect on how root method works. How is su added to /system/xbin/ without messing up the verification? Does the img file modify any of the bootloader or signing data or is it simply su injected into the file system data and /system/xbin?

Also seperate questions In attempts to unlock the botoloader I backed up LAF and dd'd dev zero over it so booting into LG's firmware update mode doesnt work and fails over to fast boot, but you cannot boot img files? Does the bootloader verify these files to? Also tried to dd the twrp img for the H851 over LAF just to test if the bootloader checks it if its signed, it didnt load and also went to fastboot.

last question can use dd to backup the LG H851's Offical unlocked bootloader and flash that to another variant to "unlock" it or will this fail?

Thanks for any responses, sorry if this is in the wrong place im new to XDA. I have a decent understanding of linux and computers so no need to be high-level.

==Update==

Just found out that to unlock the bootloader on the H811 you go to dev settings and OEM Unlock, tutorial for flashing twrp found here (http://xdaforums.com/tmobile-g4/orig-development/recovery-twrp-2-8-7-0-touch-recovery-t3164874)

Probably you have some screen overlay app such as a dimmer/filter or CPU meter running. The Install button won't respond when those are running. It's a security feature meant to prevent malicious apps tricking you into installing something nasty by disguising the button.

Hi, thanks for the info and the guide.

I have tested some of this on my international H815T, with optus branded firmware from AU.

The download mode access works, and running id shows we have a root shell while phone is in download mode.

The heading states all international are supported with this method, but then the list of firmwares says not H815T and there is no H815T provided. Is H815T supported? If not yet, need a system.img for patching? If so, what offsets to read from or how to check?

While thinking about this method, I wonder, would it be possible to directly flash the recovery partition with TWRP rather than flashing the firmware, and then use TWRP to install additional root stuff to the phone without writing the whole system partition?

Sorry if questions are answered in the thread. S/N ratio is too high to read all of it.

Hello all, a few quick questions to make sure I'm getting all the info right:

I just got my VZW G4 yesterday, came with 10b version installed, with a notification for system update available.

The current root method only works if you take an OTA to 11A, but there is a suspected bootloader update included that could patch any holes we could use in the future, preventing access. Is this correct? Is there more than one OTA update that my device could skip ahead to if I do it?

Also, the only way to get rid of the OTA notification is to root, and freeze the apk responsible, LGSMClient, correct?

Thanks in advance.
[G4 Q&A, Help & Troubleshooting] RedOCtobyr:
You don't need to root to disable updates. You can use the Debloater tool for this. Details here:

http://xdaforums.com/g4/help/how-to-prevent-updates-g4-t3148650

The "LGSMClient" client is the package you need to block, yes.

My Verizon model came with 610B. I ended up taking the 611A update because I was unable to activate Advanced Calling successfully without it, and it had just been proven that root is still possible with 611A, at least. We don't know about bootlocker changes, admittedly.

then type id

After done, I opened my phone storage then there is a file named system.img.

Then I downloaded rooted img F500L10w online provided by a forumer. I renamed it to system2.img and copy it to phone storage. Then I open cmd typed these commands

Send_Command.exe \\.\COM3

then type id

dd if=/data/media/0/system.img bs=8192 seek=65536 count=548352 of=/dev/block/mmcblk0

After done, my phone reboot and stuck at LG Logo screen.

OK,then i want to flash back my stock system.img. I type these commands again.

then type id

usually it will show uid=0(root) gid=0(root) context=u:r:recovery:s0 , but there straight show # after 1 seconds.

Then i type dd if=/data/media/0/system.img bs=8192 seek=65536 count=548352 of=/dev/block/mmcblk0

Saying that a reset will result in lost root, or a bootloop, doesn't seem consistent with what I recall reading. I got the impression that a FR clears out the user data area, not the system area.

Taking an OTA will, apparently, make you lose you root, however.

And no, rooting will not automatically prevent OTA updates. You would need to Debloat/freeze/etc the apps that download/trigger system updates with your carrier.

Short story is I purchased a G4 (VS986) that was locked via Google account protection.
