The root guide ( https://forum.xda-developers.com/g-pad-x-80/how-to/root-guide-lg-v521-t-mobile-version-t3443747 ) says you can restore using LGUP and stock .dz. Is that the only step required? Will that also remove TWRP?

Guys , some people are reporting that they are unable to revert to stock rom after flashing custom rom.
If you want to save your phone , then i highly recommend you to make a complete backup before flshing stock rom
go to cwm recovery and select backup/restore then backup (it will make your stock rom backup)
whenever you want to revert , go again to clockworkmod recovery and select restore under, backup/restore option
now last and most important thing to run stock rom ---> flash stock kernel using fastboot method
first grab stock kernel to do that , download your phones stock firmware from here = http://forum.xda-developers.com/showthread.php?p=10885406#post10885406
using 7zip extract kernel.sin file from .ftf firmware file
connect your phone in fastboot mode and run this command
fastboot flash boot kernel.sin
I'm doing it again and again without any problem.. just be sure to flash stock kernel before flashing stock rom.
thanks, i will try this method too
first flash stock kernel , then using flashtool flash firmware , am i right ?
Stock kernel (kernel.sin) is included in the package (of official stock firmware). So everytime you flash an official stock firmware, kernel.sin is also flashed. No need to flash kernel.sin before flashing stock firmware. Correct me if im wrong.
I also think same , i tried that method by noooooob and it worked too

yes you have to unlock boot-loaders first
i recommend to unlock by this method = http://androidflip.com/unlock-xperia-phones-bootloader-without-losing-drm-data-track-id-working/
if you want to install clockwork mod recovery then follow this = http://forum.xda-developers.com/showthread.php?t=1384200

This is how I did it on my Ray
I always considered flashing with Wotanserver to be the best way to go back to stock. It basically takes care of everything. Sure, you'll have to root again afterwards, but that's not exactly very hard.
wotan server is also a good choice

download firmware which you have before installing custom rom, then flash it using flashtool.

1. See you can surely flash stock firmware there is no Risk unless and until you flash 4.4.2 and update it to 4.4.4 if you do it you'll most probably HardBrick your phone so my recommendation is to flash 4.4.4 or 5.1 and never update your phone via updater...
2. And yes you'll have to flash Twrp.img after flashing stock firmware as flashing firmware change your recovery to stock.
3. Yup motoboot.img is needed to flash.
4. Refer to the batch file I've attached.
Hello,
I am a newbie into this.
I want to root the Pad to run some apps that require root access. The bootloader is already unlocked via the miflash unlock tool.
Next I tried to install TWRP 3.4.0.0 via using the guide from twrp.me
https://twrp.me/xiaomi/xiaomimipad4.html
I am able to load the image into recovery section and I am also able to boot into recovery straight after that in order to enter TWRP (using Vol up plus power button as the guide mentioned). But once the Android system is booted up the TWRP bootloader in the recovery section is gone/wiped whatever because the Mi boot menu appears again.
What do I miss out?
It is also recommend to perform a backup in TWRP before rooting (magisk) or flashing a custom rom. The backup fails with a couple of red line "unable to mount...".
Any help is appreciated. Thanks.
You are using the stock MIUI right? MIUI will automatically revert recovery back to the stock one. You have to install a custom rom to retain TWRP.

Correct still using stock MIUI. Sadly, that means root and stock MIUI won't work at the same time.

Although I never use stock MIUI, I think you can root normally. You don't need TWRP to maintain root.
Followed the instructions on several websites such as this one here at XDA:
https://www.xda-developers.com/how-to-install-twrp/
All goes well until I get to this line:
fastboot flash recovery recovery.img (latest TWRP image, renamed)
The command prompt window just sits there and says "(waiting for any device)"...
Most websites and forum threads seem to indicate that this is a problem with the drivers. Can anyone confirm?
FWIW, I did a total reflash of the latest stock ROM from this thread:
https://forum.xda-developers.com/ga...icial-stock-fw-update-odin-thread-xx-t3825204
so I currently have only the "stock" recovery.
I'd rather not root it quite yet. Help please?
P.S. The phone shows up in Device Manager and for "adb devices"; the phone's bootloader has been unlocked... can't see what I'm missing... I'm using a Windows 10 computer... I removed any screen locking mechanisms (PIN, fingerprint, etc.)...

Thanks. I'm trying it with 3.4.0-0
Do I flash this file while I'm still in TWRP? Or do I reboot the phone and go back *into* TWRP to flash it?
>After booting in TWRP download and flash no-verity-opt-encrypt-6.1 zip to disable data partition encryption
Edit: I tried flashing no-verity-opt while still in TWRP. Got the dreaded:
"Verification failed.
Unable to restart your device. The integrity verification has failed. You need to reset your device to factory default settings. This will erase all your data."
I *really* tried to follow the instructions exactly, and think I did.
Was it because I tried to flash 3.4.0-0...?
I am currently re-flashing the stock firmware again.

You need to format data after install twrp. This is avoiding internal data encrypted.
After twrp installed, do format data from twrp. Of course all of ur data on internal erased. And then take custom rom. I suggest devbase rom, this have "no verity encrypt" when u install this rom. Devbase is stock firmware for easy upgrade for rooted phone. And this is easy to install for beginner

No worries. Thank you for your help.
I use Odin to install the Devbase ROM, right? Or can I use TWRP?
Edit: apparently it works just fine to install it with TWRP.
Thank you so much. This time TWRP works just fine for me and the new ROM is great.
Hello, I have to sell my realme 7 pro and I must relock bootloader and replace recovery stock. My version is EU variant - RMX2170_11_A.36, with TWRP .
I know that I have to return stock recovery before locking bootloader otherwise bootloop.
I can't find the right recovery for my phone, i found only a.37 - a37 - a39
What are the right steps I have to follow? Thanks
Found this thread: https://forum.xda-developers.com/t/guide-relock-bootloader-back-to-stock.4172569/
Stock roms can be downloaded here: https://realmeupdater.com/downloads/latest/RMX2170EU/
Simply flashing stock rom should help?
thanks bro, I have succesfully backed to stock my phone. I've followed method 2, flashing .ozip (same version already installed) through twrp. Once done, I rebooted to system without setup, and then recovery stock was reinstalled. Then I locked bootloader again by fastboot flashing lock.
