Hi so recently today I was able to successfully flash my stock ROM from Global 11.0.3 to Europe 11.2 (20.3.5).
All works, I have a new and version specific TWRP recovery which solves the decryption issue and such.
Only problem though is I can't seem to update my ROM from the latest Europe 11.2 (20.3.12). I am aware that we cannot install OTA updates like we normally would because we are on a custom recovery. I tried flashing it from the 'choose update package' where it brought me to the TWRP and executed OpenScript to flash, and also tried flashing from TWRP itself. No luck. Bootloop into Redmi Logo and TWRP recovery, so I end up restoring the working Eu version.
An updated tutorial on how to install OTA roms on custom recoveries would really be appreciated, thanks!

Hey OP, could you make a How to install GSI guide?... I'm really interested on doing that.

you have to flash https://build.nethunter.com/android-tools/no-verity-opt-encrypt/no-verity-opt-encrypt-6.1.zip and then update the OTA..dont forget that we normally use a custom rom with TWRP, no point of having twrp with stock rom??? try xiaomi.eu , its way better and you dont have any problems with updates.

reboot to recovery
flash recommended firmware
flash rom reboot..

Hello, you are lost mate...
You use Xiaomi.eu ROM, it's a custom MIUI ROM (Not Official ROM).
You can install updates given by Updater app (System app) without issue on this ROM.
If your phone bootloop just after a ROM update, and not after flashing Magisk, it can be because of a bad encryption from "bad" TWRP (so you need to "Format Data" in new TWRP <-- installed by xiaomi.eu ROM)
-OR-
Did you use my K20 to Mi 9T conversion patch (from xiaomi.eu forum)?
Check for update with Updater app, download and install it. That's simple on xiaomi.eu ROMs.

Trying to install evolution X on my Mi 9T but whenever I flash TWRP the phone won't boot to it, just keeps loading the fastboot screen. Anyone have any ideas where I'm going wrong? I've reflashed stock with miflash for now to get it working.

I have the same problem, but I can't find a solution. Did you find it ?

I found the solution with explication on how to install havoc_OS

after format data you have to reboot to recovery, flash firmware +rom+gapps...without firmware it wont boot on some roms..read well OP instructions, mine are only for xiaomi.eu, you dont need to flash firmware and it will boot fine.
