Back to MIUI 12 from custom rom - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

After trying out two custom roms and running into little bugs that make me pretty nervous, I thought about going back to the official MIUI 12 global.
Is it possible or is there a possibility of brick? It would be enough to put the rom and the vendor and flash them from twrp, making the corresponding wipes?
Do I need the vendor or just the rom is enough?

It won't brick you just have to format data going to and from custom rom and miui with encrypted storage (not using dfe) or your data will be encrypted. Then just wipe the partions and move miui rom to phone from PC and flash, miui has vendor included in the rom

May do a fastboot flash with clean all. Careful not to lock your bootloader.

Mi8 Doesn't Boot

I have installed TWRP and then wipe everything(including Internal Storage accidentally). I installed xiaomi.eu stable rom and phone stuck at MI android screen. Then try xiaomi.eu beta rom it is same.
What should I do?
If you have unlocked BL use mi flash to flash stock rom
Flash stock rom using miflash 2018 (portable) since your bootloader is unlocked, make sure you choose clean all, DON'T choose clean all and lock at the bottom of miflash screen before you flash the rom, other wise your device will be bricked.

Thanks, it worked, I solved it by installing rom with fastboot and I know why TWRP doesn't work. Because of encryption. https://forum.xda-developers.com/android/software/universal-dm-verity-forceencrypt-t3817389

Impossible to boot AOSP/Lineage ROMs on global

Hi,
I have the Mi 9T Pro global (not EU, China or India), and the only ROMs I have been able to boot are Xiaomi.eu. I've tried flashing HAVOC, Syberia Project, Evolution X and C-Droid following their instructions, the results are always the same: black screen, and TWRP becomes unaccessible, even if I try reflashing TWRP from Fastboot, it won't let me. Then I have to boot into Fastboot and flash stock ROM using Mi Flashing Tool, and flash TWRP from Fastboot again. What am I missing?

At the point where you normally wipe data, dalvik and cache, before installing the ROM, try formatting data instead and wipe the other 2.

I tried formatting data, as it is part of the instructions of one of the ROMs I tried to flash, no success.

What version of TWRP are you using? If you're using something different then try 3.3.1-15 from here. https://forum.xda-developers.com/k2...icial-twrp-xiaomi-redmi-t3944363/post79823568

Exactly the latest one from mauronofrio, no other, as I even tried flashing Orange Fox and it never got into it, forcing me to reflash stock again to flash mauronofrio's TWRP.
I followed instructions from the ROMs I tried, none of them seem to work.

What stock ROM are you flashing?
Are you flashing on top of an Android P or 10 ROM?

you are the same with me..im on mi 9T pro running global 10.3.1.0 PFKMIXM..no luck flashing custom rom..now my 10.3.1.0 rooted + quax kernel..even cant flash quax custom kernel on 10.3.2.0..always goes to fastboot mode after done flashing and click reboot into system via twrp..now im stuck on 10.3.1.0...also im using the latest twrp too..
Same here. I can install eu miui roms but cannot install any aosp based roms. Goes straight back to fast boot. Went back to using eu miui roms as of now.
Can anyone suggest what is going wrong. Seems like once you install an EU rom you cannot go back to any aosp roms.
I'm thinking about the vendor. I remember a post saying that our firmware or vendor are weird and try to revert to stock, and need to be patched. But I can't find that post anywhere. I've tried all suggestions: format /data, flashing Magisk, flash ROM and GAPPS and wait for boot to complete to flash Magisk (never got that far).

Solved. The issue is with the vendor files. I've flashed fastboot chinese rom and then installed aosp rom and it worked.

1. Do you have global Mi 9T Pro?
2. Could you please share the files you used and the steps, so we can all try?
Thanks in advance

Also, is there any risk to brick or lose bands if flashing a Chinese vendor on a global phone? I don't want to lose the only LTE band in my country (700 b28)

No you won't lose any bands. Same as you don't gain bands when flashing a global ROM on a Chinese/Indian phone

Yes, format data, reboot again to recovery, copy the EU rom into internal storage and flash it, mind you EU rom will replace Orangefox with twrp

Yes, you can flash minimal versions down.

You earlier mentioned Flash tool, well, you should flash it using SPFT. Take care to use the option Format data, I would advise to not use it at all, you have to only flash it, in the case you want to preserve data, then don't flash this partition, leave it blank.
