Need help rooting. PLEASE HELP - T-Mobile LG G4

I have been trying to root my lg g4 h811 6.0 in order to recover deleted files. And all on-click-rooting programs have failed due to an unknown error, along with numerous usb connecting programs. Any other guides require me to enter the recovery mode... Which seems to not work. I have run out of options. Any concrete guides or answers would be much appreciated!

you need to unlock bootloader and inject twrp then install twrp within twrp. and then root.
this guide works in any 20x NOTE theres antirollback if you are in a version over 20o either 20o-20p-20q-20r dont flash 20i cause its antirollback V2 from 20o to 20r its V3. so if you in 20o or higher dont flash 20i. just use same steps but with the version you have either 20o-20r.

Successfully installed boot image, knox is intact (it is still zero), but there is no root. After installing boot img i'm always getting error "Security Notice Unauthorized Actions Error" or something like that.
I'm using same firmware and baseband as mentioned in first post, i didn't tried your firmware because there is userdata partition inside of archive and i don't want to delete my data, at least before i root my phone and make good backup
Please help with root.
Edit: root works with adb after installing patched image
Thanks for your work.

@zogu what do you mean using adb? Can you describe your step? Here what I try but still cannot root the phone.
1. Odin @diart firmware
2. Odin diar-uca_root.zip
3. Recovery mode & adb sideload supersu, both fail (verification blablabla issue)
I got same "unauthorized actions has been detected" notice like you, but fail to add root with chainfire supersu. Trying all one click root fail too. Can you help to describe your step?

Ah, ic.
Still cannot root my phone even with other rooting tools (not try furious gold chimera yet, doesn't have it). But thanks for you @diart & @zogu anyway. you two give us hope that there's any possibility to root our AT&T S6 Edge phone.
Can someone tell me how to do it, please?
Boot image from first post is engineering boot image and it should works with all 6.0 firmwares.
I'm new to samsung, but i read that with this image is possible to remount system rw. Well on AT&T is impossible.
It is impossible to root phone with this image, but we can do a lot of useful things using adb, disable aps with pm disable, we have full access to data partition, making backups etc...
Actually i don't need root at all, i hate branding (specially if that includes some services, like at&t mail, phonebook...) on any device and i want to change firmware to some international.
All this is maybe possible with eng sboot. There is online available for 12 usd and this is not expensive, but i'm still not shure will i be able to change sboot to 925f.
Theoretically it should boot any kernel and recovery without even tripping knox, and maybe with this image is possible to install twrp, kernel, root and everything else. But also sometimes everything does not work (i read that with eng sboot fingerprint sensor does not work, it probably skip keys reading, without keys no fingerprint).
If someone is able to get sboot pj1 or pf1, please send me PM
P.S. One good thing with this eng boot is that my network selection menu has much more bands, even when i restored stock kernel. Don;t konow how, but it is there

my friend im flashing this file but odin md5 error binary is invalid ? how to fix ?
Just rename from md5 to tar. File name should be sm-g925a_uca_601.tar, flash it using odin (AP) and that's it.

P9 EVA-L09 stuck on Nougat

Hello guys,
i did a mistake yesterday and accidently hit the update button of the official update dialog from mm to N on my p9. Because you cannot cancel it, it proceeded the whole process...
Now i'm stuck on the new Version and first problem were missing apps like updater, and camera?!
I was looking for the new buildnumber and it says NRD90M test-keys.
Previously i was on root but dont know the buildnumber (some MM), bootloader is unlocked.
I searched a lot on xda but did not find a similar problem with a solution that i would try.
Can anyone help me how to fix that problems? I read about a rollback but didnt find a way to do that. TWRP is loading if that helps in any way.
Goal is to get root to work with magisk maybe and an up-to-date nougat rom (and Camera back since 3rd party isnt that great).
If any other info is needed ill provide that.
Thanks in advance!
I did some research an tried a few more things.
Here's whats not working:
-flashing b136 with dload from paulobrian's thread. fails at 5% mark
-relocking bootloader with srk-tool and fastboot. resulst in: failed remote root type is risk
-flashing several other full versions
i flashed (succesfully) stock recovery following this tip: https://forum.xda-developers.com/showpost.php?p=67754200&postcount=4
system is booting but weird behaviour as described.
I read something about succesful flashing stock only with locked bl and only locking bl with stock recovery but this doesnt work for me.
Any tipps are much appreciated.

Honor 5C Fastboot Loop (image verification error)

I have been using my Huawei Honor 5C for 6 month. Week ago, I decided to try updating my firmware from android 6 to 7. I have bricked my phone at all, as FRP was locked. I bought a DC Phoenix license and flashed some files, which I recieved from DC Support.
Everything was OK, but two days ago I tried to root my phone and install TWRP. When I try to do that, it gives me:
Fastboot: FAILED (remote: image verification error)
Contacting with DC Support doesnt give any help, as they dont know why it happens.
Did smb has the same problem as mine? If so, how did you solve it? I dont wanna buy DC license for a second time

You probably messed up like me.
I think you should download full update of the 6.0 firmware and then ^take out^ boot.img recovery.img. And system.img. Then install it through adb. 1.boot 2.recovery 3.system. It should help.
Someone told me about it in Nem-L21 Nougat tread.
I left my in Huawei seewis centre. They exchanged motherboard - it Was easiet way for them.

I have already tried it. I downloaded NEM-L51C432B130 FullOTA, unzipped it using Huawei Extractor app and flashed boot, cust, system, recovery and recovery2. After that, i rebooted my phone and had a critical error screen, which said me that I need to flash system partition (but I have flashed it). I also tried flashing rollback first, but it gives the same error. Finally, I fully flashed beta rom of android 7 and the phone has booted. The problem is that one archive of Android 7 rom has extra "data" folder, which contains system apps such as Bluetooth, Finger Scanner, Update Utility, EMUI Explorer and some others. Without them I cant use my phone, cause I often use these options. This archive with "data" folder needs to be flashed through TWRP, but I cant install TWRP on my phone (see thread question). I dont know what to do...

I know. I has Nexus 7 and it has the easiest way for flashing firmware. I dont understand why Google (or Huawei for EMUI) didnt preinstalled a small extended board with stock ROM for rescue purpose. So that, if somebody bricked his phone, he could be able to fastly rescue his phone and make it work. The worst problem of fastboot is that fastboot partition can be damaged, while you flash something. Anyway, android devs are better made FRP lock, which is useless and can be easily removed... Or they are better made some new androids every 3-6 month, wow, thats cool (no)
This problem had no solution yet. There is only one way, how I could make my phone fully-workable - wait for a stable ROM of Android 7 abd flash it through fastboot.

Yes, I totally agree.
And I am waiting for the Nougat release - after the beta I am missing some options - like dualscreen.

Tmobile lg g4 bootloader twrp supersu

Hi,
Im kind of late in terms of LG G4. But it it is now my curret phone. Have expierence installing unlock bootloader installing twrp and supersu on motorola phones. Owned a LG G2 and bricked it because of flashing wrong files.
There are alot of variants to LG phones...compared to motorola that create a higher risk.
So im trying to be cautious here.
Ive done my research and found this link.
https://forum.xda-developers.com/tmobile-g4/development/stock-h811-20i-images-kdz-flashable-t3308227
Can someone confirm that this will work on my LG G4 T mobile 20v with 6.0 marshmellow?
From what i understand i just skip the first step Flashing the imagee (because it is for the 20i) then continue with the normal routine? Is this twrp and supersu compatible?
Is there a way to restore my variant stock rom if i screw up?

These instructions are more up to date and accurate! - https://forum.xda-developers.com/tmobile-g4/general/how-to-unlock-bootloader-flash-twrp-t3344421
on line 10 change the command to 'fastboot boot recovery "NAME OF TWRP FILE" - this will boot twrp on the phone itself, then from phone install twrp and supersu from your microsd card
you need to put a copy of twrp in the adb/fastboot folder on your pc and twrp and supersu on your microsd card before starting, to avoid mistakes name them recovery.img and supersu.zip
latest twrp: https://dl.twrp.me/g4/twrp-3.1.1-1-g4.img.html
latest supersu: https://s3-us-west-2.amazonaws.com/supersu/download/zip/SuperSU-v2.82-201705271822.zip
rooted with recovery installed, thank you
can I flash any tmobile custom rom for the lg g4? or will it cause brick too?

Start the backup and wait at least 10 min. The screen should become responsive after the backup has finished - normally sooner but it is not crashing just using all power available.

Update OP3 from 3.1.2 to OOS 5.0.1 (process and files required)

Hi guys, I have a OP3 which is running on 3.1.2 Marshmallow.
I always get a notification for system update to 4.5.1. I've tried downloading and installing the update but after the first boot my OP crashes/gets bricked. There is only a Linux penguin logo that appears no matter what button you press.
From there I always have to follow the mega unbrick guide and get my phone back to working with stock recovery and 3.1.2.
I've tried side loading the downloaded file as well.
Then I've tried installing .zip file of 5.0.1 via TWRP, still no luck. it still bricks my phone.
Am comfortable rooting my phone, my bootloader is unlocked. I don't care too much about keeping root after updating my phone to the latest version, I would be grateful to anyone who can point me towards the proper full ROM files of 5.0.1 along with any firmware files that may be required.
And the exact process of when to flash the firmware and with/without which version of TWRP. I am ready to completely wipe and clear data.
in simple words I just want to update from 3.1.2 to 5.0.1. The simple downloading and updateing from the OTA update doesn't work.

I though of running a diagnosis check by dialing *#808# and looked up Charger option, it shows the battery as "itech_3000mah"
is that original?
I had given the phone to repair for water damage to a professional service chain (Not OnePlus, some company here called Yaantra). I've heard from talking to an official repair person of OnePlus that fake batteries are not possible for OnePlus.
The battery works absolutely alright, charges up nicely and I get decent SOT. Can't complain at all.
