Good Evening,
AT&T LG G2 rooted, TWRP. Have installed a few different roms but mostly used PA. All of a sudden the phone started experiencing issues with cell Data. So I did a clean install of PA and then had issues with BT, did another clean install and had issues with Wifi.
So I decided ok maybe its time to go back to stock. Hook it up to a win7 computer... Device manager doesn't see it at all (doesn't show up AT ALL). Says charging and that is it, does not recognize that it is hooked up to a computer. Have tried several different computers now and several different USB cables. The only way I could try other roms was downloading via wifi. Tried a stock rom and still experiencing issues.
I think there is something wrong with the phone so I want to get it warrantied, but without hooking it up to a computer I can not figure out any way to remove the custom recovery or revert it to stock.No matter what I do no computer will even recognize the phone is connected, let alone trying to install drivers. Device manager just straight up does not see it.
Any help or suggestions is GREATLY appreciated. Any way to remove recovery/root without a PC connection?
UPDATE: Here was my solution
Took some work but I figured out a way to do it in case anyone else ever runs in to this:
(make sure you are stock rom or on a stock rooted rom before proceeding)
First download the stock recovery.img on the device.
http://downloads.codefi.re/autoprime...10B_Partitions
Then download/open Terminal Emulator and type:
su
Then
cd /sdcard/downloads
Then
dd if=/sdcard/downloads/recovery.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
That replaces TWRP/CWM with the stock recovery.
Then open supersu, go to settings, towards the bottom is full unroot.
Yay no more custom recovery or root on stock rom.
If you are planning on getting warranty you need to use download mode and the back to stock guide also that is the best way to flash to stock and get rid of problems

Agreed, problem is the computer will not see the phone, so I can't use the program to flash it back to stock.
It's not just a driver or com issue, the computer does not see it AT ALL. Device manager doesn't see a new device when I plug it in (in OS, in Download mode, nothing).

Have you tried different usb ports also very important are you using original cable that came with the phone in my case if I try many of the different cables I have, only the stock one works for download mode

Different usb ports, different computers, different cables (stock one included). No luck. Phone says download mode then goes to "firmware update" and says at the bottom B53 then "ROOTED" in red letters. Nothing appears in device manager.
In android regarless of rom if I plug it in it doesn't act like I plugged it in to a computer, just charging. Again nothing in device manager regardless of USB debugging or not.
currently have twrp 2.6.3.3, running D80210b 4.2.2, with baseband M8974A-AAAANAZM-1.0.190034
What I really need to know is if there is any way to restore stock recovery and remove root without using that method (ie using Terminal Commands or flashing a package, since I can download via wifi).
I am pretty sure this phone has a messed up USB port, but I don't really want to send it in with it rooted/twrp on it .

Did you try restore & reset functionality on the phone? I had somewhat similar issue with the plug & pop feature (although my laptop recognized the phone under Devices & Printer but it didn't show it as a separate drive) when I flashed CM11 but then I did a full factory reset, everything goes back to normal. Also you might try uninstall LG driver and reinstall it. Hope this help.

Unfortunately it is not a driver issue, it doesn't show up in device manager at all, on several machines.
I have tried multiple different roms, factory rests, even tried ADB sideloading, no luck.
i remember there's this app called Auto Rec that has an option to unroot the device or something like that.
Took some work but I figured out a way to do it in case anyone else ever runs in to this:
First download the stock recovery.img on the device.
http://downloads.codefi.re/autoprime/LG/LG_G2/VS980/Stock_Firmware/10B_Partitions
Then download/open Terminal Emulator and type:
su
Then

That replaces TWRP/CWM with the stock recovery.
Then open supersu, go to settings, towards the bottom is full unroot.
Yay no more custom recovery or root on stock rom. (this was after flashing a rooted stock rom by downloading it on the device itself since I had no USB).

So did this worked for you? And what about your warranty?
I have an issue with the vibration and I am thinking of going to stock and send my G2 to LG.

It worked perfectly and I got the phone exchanged without any hassle, but if your USB is working there are plenty of better ways to return to stock. This was an option I had to use because of USB not functioning. I mean this would allow you to unroot without wiping/restoring but if your going to send the phone in anyway you might as well wipe it as well.

I understand and thank you for the reply.
I am a bit afraid of the other methods I saw and this one seems easier
I have a question if you can answer to me.
I restored the official rom from TWRP and did all the process you wrote. Is there any way to check if now I have the stock recovery?
And to see if I am now ready to send my phone to LG?
P.S. "I will hit the thanks button tomorrow because I have reached the limit of 8 thanks per day "

Just reboot to recovery, you should get the stock LG recovery instead of TWRP. If you unrooted as well, you are good go. Glad I could help! No worries on the thanks .

So I have to congratulate and thank once more this man @crawlgsx for this great thread.
It worked on my D802 (international model) and got it repaired by the official service center of LG in Greece.
Great work, with no need of PC and difficult processes.
Noob question, but will this allow users to take OTA updates? Running stock rooted right now and really don't want revert to stock to get latest ota, but this seems pretty seamless. Thanks.

I believe that in order to take OTAs you must be on stock rom and stock recovery. Be rooted will not be a problem if you have these stock but when OTA installed you will lose root access.
If I am wrong, correct me someone.
Hi
Sorry to bump this thread but I need to unroot my AT&T G2 800 so get the warranty.. I had taken the stock backup using twrp.
Can I restore the restore it using twrp ? and do i need to install Terminal emulator on my restored stock rom and then do the commands ?
Are there any chances of bricking the phone ?
Hi all,
I have very minimal knowledge when it comes to Android development - I have never flashed a rom, but I have rooted my phone. Recently, I purchased an AT&T Note 3 from my little brother after he had tried his hand at modifying the phone. He rooted it, flashed Knoxraid, didn't like it, and wanted to revert - he removed root, kind of stupidly, before doing anything else. Now, the phone runs Knoxraid, but isn't rooted and I have been unable to get root again. What am I doing wrong, or what don't I understand?
Thank you all.

download this here and unzip it when its done http://www.sammobile.com/firmwares/3/?download=25106 its android 4.3 so if you want kitkat make sure that kitkat has a root guide if there is one.
download odin here also https://mega.co.nz/#!UdRRyCAT!H4FyVxYynNWvXqRNmnpMGQRCP-dG3uykgP2pT4rh8Ek unzip it as well
Take out your battery and go into download mode (press and hold Home + Power + Volume Down buttons) open odin and connect your phone (in download mode) to your computer, make sure in odin one of the id:com boxes changes color after you plug in your phone. (i dont know what color it is in odin 3.0.9 i have older samsung phones so older odin name for me lol) select AP and select wherever you put the firmware, Make sure re-partition is NOT ticked after that click start and sit back and watch, be sure to move your files onto your computer if you need any from it like pictures/music.
Hey guys!
So this n00b was going to get rid of all the bloatware on SM-G920F using the following ROM:
http://forum.xda-developers.com/gal...xtrestolite-deodexed-mod-edition-1-3-t3119968
So i used ODIN 3.10.6 and chainfire CF-auto root: https://autoroot.chainfire.eu/
what i missed here is that this auto root was for 5.0.2 and i have 5.1.1
I'm guessing that this is causing my bootloop or bootfreeze?
I can't switch off my phone, screen is constantly at the "GALAXY S6 POWERED BY ANDROID" screen with the small red text "recovery is not seandroid enforcing".
If i hold the volume down, home and power button it will restart/reboot but still be stuck on the GALAXY S6 POWERED BY ANDROID screen.
So what now? i have to wait for the battery to die before i can try to get it in download mode or maybe even recovery mode?
What info do you guys need in order to help? i'm sure there is a simple fix? I'm in Sweden btw
EDIT: So only 2 hours after posting this the screen had gone black... and waiting another 20 minutes i tried to boot it in download mode, and it worked. @ Work right now so i want to try fixing this later today. So any one know for sure how to undo my root that failed? Can i Flash all stock by using Kies3 in download mode?
Appreciate your help guy's
EDIT 2: I can boot to TWRP... tried wipe and recovery. do you think i need to wipe/format data? If i format data what would be my next step? come on guy's help me out here
I think the wrong change of cf-auto-root causing this bootloop and bootfreeze, so if you want to get root change the right version of cf-autoroot. If you want to Flash all stock rom i advice to use odin because i dont know if kies3 can recognize your device

This is what i think as well... You don't happen to know where to find a good trusted root for the galaxy s6 F920F?
Phone started!!
OK so i got the phone up and running again.
i flashed this kernel: https//github.com/AndreiLux/ref-3.10/releases/tag/alpha3
So RGB colours are different and youtube way worse. So this brings me to my next question; Can i do a factory data reset now? Will it make my phone standard again?
I am talking about the factory data reset from settings/backup and reset/Factory data reset... that will erase all storage, device settings etc....
if not... how can i turn my phone back to normal?

To get everything back to normal...
Download latest stock firmware for your phone from Sam Firmware and then flash it via ODIN. Just do it
It will reset your phone, but probably not the contents of internal /sdcard.
Dont use CF-AutoRoot as its not compatible with 5.1.1 anymore. To root your device, just flash any supported kernel you can find for Galaxy s6 as it has preinstalled root in it.
Dont use you CF-Auto root in 5.1.1.

Will this firmware work for my phone? it is for my country.
thanks for your help so far!
Yes it will work, though if you're from 5.0.2, you can't downgrade anymore after flashing 5.1.1(COI9 based).

Can anyone help? I spent a big chunk of my hard earned money on a refurbed S6 for my daughter, she's had it about a week (she's Pokemon mad btw). The latest update for Pokemon Go came out and now she's blocked from the game as it appears the phone has been rooted. If I'd known, I wouldn't have bought it. Anyway, for the last 2 days my partner and I have been trying to unroot it. We've used various versions of Odin to no avail. I had a lot of trouble finding the right firmware because it looks like the phone was Polish according to the version and CSC numbers, and tbh I'm still not sure if we're trying the right one. Software is 5.1.1. right now. I've tried installing SuperSU but it won't run, it just crashes the phone and forces a reboot. We've tried manually unrooting with a file manager but the su files we need to delete reappear seconds after they're deleted. I'm at the end of my tether, does anyone have any ideas?
You won't be able to unroot it until you flash stock firmware. I don't know if the game checks the knox status.
Give this a go

Unforunately my partner spent almost all night trying to flash the firmware. According to him it 'nearly' worked, however, I now have a phone stuck in a boot loop. :crying:

Smart switch won't work, says it doesn't recognise the device
I think I would give original firmware of your country and odin a try. One of possible ways is to download all needed files from the site of sammobile.
For me this way works every time when I stuck in boot loop. Odin functionates when you are in download mode. Switch off your s6, then start by pressing home-, powerbutton and Volume down at the same time.
Then start Odin on PC, then connect USB and so on.

When you select emergency recovery theres an option where you have to write the device model and the serial number
Use kies 3 on your computer. When you get it do a "firmware upgrade and installation" it will ask for your serial number which you can get from download mode when pressing the home key. After that kies 3 will ask to boot your phone to recovery but instead boot to download and bow your phone will flash to stock. This method always work!!

Thanks for the reply. Unfortunately I've tried Kies already and I can't get it to work at all. I get a message telling me my device is not compatible and the whole thing just stops. I'll give it another go though, no harm in trying. Thanks
@amber_1978, Pokemon Go does not check for root. The only thing it does seem to check for is location spoofing via another app. I'm using it on a rooted, Knox tripped, Xposed installed phone with no issues.
If you want to return the phone back to stock, the best way IMO would be to use Odin to flash a stock image, such as the EPD1 firmware.

Really? Did you do the latest update in the game and it still worked ok? This phone has definitley not been used for location spoofing by us and I'm pretty sure there were no apps of that nature on the phone. I downloaded a root checker when everything went wrong the other day, it said the phone was rooted. I'm totally at a loss tbh. Right now it's still in a boot loop. Trying to flash it with Odin as we speak.
Just an update. Tried Smart Switch. Tried the model and serial numbers on the back of the phone case, these weren't recognised so I went to the recovery screen and hit the home button and got a completely different set of numbers. Different IMEI, model number, you name it. I'm assuming this is why Odin won't work, I'm looking for the wrong firmware? I obviously have Frankenstein's phone. No idea what to do now.
Best thing to do is to flash TWRPP and try to flash a custom stock rom through the TWRP recovery which does not have root installed..... If that doesn't work try to find a generic stock firmware for Odin, meaning a firmware that can run in any country..... If all else fails update it to 6.0.1 stock firmware. Try the closest firmwares to your location.
And if you do manage to get to the Samsung logo let the phone sit there for a good 10 minutes even if it reboots....
When I bricked my Samsung I used masiks custom 6.0.1 rom based on stock, but had all the links to bootloaders cscs radios and what not so giv that a shot if you can find it.

When I try to start up my phone I get a screen like the ones you see on broken TVs where it's kind of a fuzzy mess and normally end up on the kernel panic thing. I can't get my phone into recovery mode or anything. I rooted my phone a while back and accidentally lost it through an unroot tool, ever since my phone has been unstable but now this has completely ruined it. If someone could shed some light on how to fix it that would be perfect, thank you.
