How do i unroot my LG V10? - T-Mobile LG V10 Q&A, Help & Troubleshooting

Is there a way to unroot this device?
Thanks in advance

You'll need a computer and TWRP recovery installed on your device.
Assuming that you have those prerequisites, simply flash the stock ROM in TWRP like you would a custom ROM (the .zip can be found here: http://forum.xda-developers.com/tmo.../lg-h901-stock-images-device-restore-t3241170)
Once you have that flashed, you can reboot into fastboot mode and install the stock recovery image using the "fastboot flash recovery recovery.img" command or by using a flashable .zip (the stock system images can be found here: http://forum.xda-developers.com/showpost.php?p=63604156&postcount=1)
That should do it.

Would need to lock the bootloader if returning it or selling it. Do that last tho

[Q] Help rooting new HTC One M8

Okay so I unlocked my bootloader using the toolkit but I dont want to flash a custom recovery, I like the stock one. Is there anyway I can root it using the stock recover?
You can do a temporary recovery image boot.
You must know fastboot commands and must download a recovery image and a super SU zip.
1. Boot into bootloader
2. Fastboot boot recovery.img
3. Once in recovery, MAKE A BACKUP
4. Install SuperSU.zip
5. Reboot
6. Check root once rebooted
You will retain your stock recovery, and your backup will be of the stock system. This will also not give you a tampered flag, at least in my experience

First time flashing twrp with fastboot you need to flash a modified boot image as well.
Either TWRP version would be fine.

How to root with stock recovery?

Hey folks,
I just updated from b130 to b340 marshmallow and removing TWRP was a pain in the ass, as I wasn't able to update without stock recovery... Took me hours till I found a working method, as flashing the recovery.img from the official update didn't do nothing...
So long story short, I want to stay with stock recovery now so that I can receive OTA updates and stuff. However, I'm unsure on how to root without TWRP. Stock recovery doesn't seem to have an option to flash the supersu archive, so yeah...
Anyway know a way?
Or you can flash your TWRP recovery in place of your eRecovery, in order to do that follow these:
Boot your phone into bootloader mode.
Once in bootloader mode fire this command to flash TWRP recovery in place of eRecovery.
Code:
fastboot flash recovery2 twrp.img
Where twrp.img is the name of your TWRP recovery.
Hope this helps you.

How to flash stock recovery.img

Hi, i have a stock recovery image and I'm wondering how to flash it, can i flash via TWRP install image option or via ADB, and if via ADB how to flash it?
you can do it the both ways..
in twrp , you have to select install image option
in adb, going to bootloader and performing same procedure as you did for the twrp

[Help] Bootloop on Xiaomir Redmi Note 4X

Hello, I'm kind of new at this (this is my first post) so be gentle
So, the last few days I've been trying to install a new rom on my phone (Redmi Note 4X) and the problems started with the model. I only seem to find Redmi Note 4 roms, and as I've come to find, mine is supposed to be the mido one (correct me if I'm wrong though). I have unlocked the bootloader, I have installed and enabled the fastboot on my phone, so the next step was to install the latest TWRP.
There came more problems; I tried doing this through the app and it just wouln't flash it. So I found a guide on how to root my phone and install a new recovery through adb and I followed it. It didn't work. I couldn't find the right twrp version for my phone. When I finally did realise my phone needed mido, I found the latest from the TWRP website. It wouldn't load through adb again. I found a thread about a fixed mido version, which finally worked for me. But my brother who was helping me, and isn't as much of a noob as I am (he has flashed rom and recoveries many times on his Nexus 5X), decided that I necessarily need the latest twrp if I'm going to flash a new rom, so he flashed the new twrp through the old one, and soft bricked my phone (I think). So I'm searching for a guide to unbrick it. (Which I can't seem to find to work at least).
To conclude;
I have unlocked my bootloader
I have access to the fastboot
I tried to flash a recovery
I failed many times, but I managed it
I flashed the latest twrp and bricked my phone
I don't have access to the recovery
My phone is still on a bootloop
I am not sure about which phone model I have
Help!
Thanks in advance.
1. Just check your phone model on its box. If its Snapdragon version (Mido), then just install it via fastboot. (code: fastboot flash recovery twrp-midoxx.img). If you are success, then try to reboot to recovery (fastboot boot twrpmido-xx.img). After booted, then you just manage to rom.zip you want to install. If you don't have it, then download it before from your PC and push it to your phone. Or just enable Mtp checklis from TWRP n copy that file to your internal phone/sdcard. Wipe all/factory reset except internal storage. Then you dan install rom.zip normally. N reboot. (Note: if you are on MIUI and wanted to always stay on it, just flash the file called lazyflasher.zip. n' wipe cache n art cache only then reboot). Flashing custom recovery on stock MIUI Will manage the device Going to bootloop)
2. If you have mediatek version (nikel), searching the fastboot Rom from miui website and flash it normally via fastboot. (SP Flash tool)
Warning: flash the wrong rom file into wrong phone Will make your device brick. So becarefull n knowing what model/code name you have.

Hello and thanks for the reply. I have the snapdragon version, but all I'm asking is how am I supposed to flash the lazyflasher without accessing the recovery? Through adb?

Firstly, enter fastboot mode on your device. Connecting to pc and flashing the twrp for mido. "fastboot flash recovery twrp-mido.img". Then boot to it using " fastboot boot twrp-mido.img". Then you will enter the recovery (twrp) in a second. Copy the lazyflasher into your phone (enable mtp first in Mount option in twrp) that you downloaded from pc. Just flash the lazyflasher.zip and reboot.
And why you don't want to flash lazyflasher when it very easy to flash it using recovery twrp? adb? You mean android debugging? Actually, you cant flash a .zip file into your system partition except through fastboot mode. However, fastboot mode (in cmd) only recognize a .img file. I just try to tell you the easier method to make your device boot up.

As I said above, I can only access the fastboot, and I get errors in the adb when I try to flash the twrp image.
