U can install stock rom using twrp.
If rooted (magisk) you can easily uninstall it in its settings.

Patched stock MI recovery

I found this https://forum.xda-developers.com/mi-9t/how-to/root-k20-indian-rom-v10-3-6-0-twrp-t3958566 regarding rooting the phone by using a patched stock MI recovery, to include Magisk in it, then flashing it into the phone so we have a rooted ROM without installing TWRP.
This guide is for Mi9. Is it applicable to mi9t pro too?
Also I wanna ask how we can relock the bootloader, assuming we are in the stock ROM the phone came with.

First of all it's not a patched Mi Recovery.
This method works with Mi 9T Pro and almost all phones. What you do is just patching the boot.img and flash it. So you don't need to flash TWRP and you are rooted.
IF YOU DO THIS, NEVER LOCK YOUR BOOTLOADER!
To be stock means no patches, just nothing! Fully stock!
To lock your bootloader use MiFlash.

Thanks for the response.
I assume that, if i flash the patched boot file, I must reflash the untouched boot file in order to relock the bootloader?
I just wanna be very carefull with my new phone ...

Yes.

Hello again
All went well.
I unlocked my bootloader
I patched and flashed the boot file
I rooted my phone (eea 10.3.3.0) without TWRP
What happens now with the official OTA updates?
Will my phone be updated normally?
If it will be updated, my root will be gone?

Yes if you update the root will be gone, you'll have to patch the new version's boot image.

Mi 9t pro stucked in mi recovery

Last week i updated my mi 9t pro to miui 11 EU by OTA. This morning i was trying to boot it but he go in mi recovery. How con i solve this problem without losing my data? The bootloader is locked. Sorry for my bad english.

Try a fastboot firmware. There may be bat file included to preserve data. If not, at least you can get your device working with a locked bl.

[HELP] How to return MI A2 to factory system

Well, friends ... this is it.
I converted my Mi A2 to Mi 6x and everything was working fine. One day I decided to return my smartphone to the factory system, but unintentionally deleted all files within TWRP. Now I have the following dilemma:
I can get into TWRP and fastboot, but when trying to install any ROM by MI Flash (Jasmine_Spout or Wayne) the program says "Can not read from port COM *).
Can someone help me?
PS: Forgive me, I'm from Brazil and I'm using the translator to write this text.

Hi there, you can revert back to Mi A2 using Qfill or mi flash 2016 64 bit in edl mode, see this thread for details:

Installing recovery in K20 Pro :( :( :(

Hi, I have a problem installing the recovery. After installing it correctly and restarting the phone, I can't enter the modified recovery and I only get xiaomi's. What can happen?

The custom recovery gets replaced by MIUI recovery every time you restart after flashing it. Orange fox recovery is highly recommended. Flash recovery, flash magisk and disable dm-verity over it.

Yes, "Universal DM-Verity, ForceEncrypt, Disk Quota Disabler".

There is no need to permanently disable encryption, if you do not want to.
See my previous answer in the official TWRP thread

You must start the new recovery right after flashing it. You can do this with
Code:
fastboot oem reboot-recovery
