[QUESTION] How to safety flash custom rom? - Xiaomi Mi A2 Lite Questions & Answers

Dears,
In the past i flashed custom roms on few phones, but Mi A2 Lite is my first phone with A/B partition and with GSI ability.
1. There is any particular changes in flashing procedure in comparision to, for eg. my previous phone Redmi 3S? (fastboot oem unlock, fastboot flash recovery, install rom in TWRP and voila),
2. If there is - can someone explain it to me? Or maybe there is some good guide with wrong tags and i can't found it.
I have v10.0.12.0 rom version (july update).

Flashing TWRP on Unlocked AI China version Note 5 MIUI 10.

Hi All
I am trying to flash TWRP 3.2.1.2 on my Redmi Note 5 AI China version on MIUI 10.8.9.20 Beta
but I am getting an error (failed anti-roolback check). Anyone know of a work-around for this or is it no longer
possible to flash TWRP. My phone is already bootloader unlocked.
Hi there,
You should be able to see the guide on how to twrp on of the theads here.
After you get that error you must flash a dummy.img file into the recovery then last step is to flash the twrp file again.
It should be sucessful after doing so.
Let me know how you go

Custom ROM installation - which Steps before?

Hi guys,
I want to install a custom ROM to my Xiaomi A2 lite. I am currently on Android 9 (V10.0.20.0 PDLMIXM) Stock FW.
I have flashed custom roms before to other devices (Samsung and OnePlus) but I'm kind of lost with the Xiaomi A2 lite.
Which steps need to be done first in order to flash a custom rom? I know for sure that I'll need a recovery image (TWRP), but which other steps are necessary?
For example:
- bootloader unlock?
- rooting the device?
- flashing a fastboot image?
I found loads of threads in the subforums, but no guideline on what to to first (and in which order).
Could somebody point out (by linking to the threads)?
Cheers!
Hey. Just follow this guide, works like a charme.

First you have to downgrade to Android V9, i don't remember which MIU Version that is.
@mxpower, this is strictly not true, I have been able to install Pixel Experience ROM straight from the Global ROM V12.0.3.0.QGGMIXM A10 without needing to downgrade first.
I followed this CFW migration guide correctly (method 2) with no bootloops and all working correctly.
@perlene You probably flashed the wrong TWRP version, to be safe, Flash full MIUI firmware from SP Flash Tools or via fastboot and start over again
Same problem, I have tried few different twrps since yesterday, same keep bootlooping!! every try after flashed with full Miui firmware from Mi flash, still the same.

In these threads you should find the answer to your question.
Also I advise you to NEVER BLOCK THE BOOTLOADER if there is a rom other than the original in the phone, go brick.
To be able to block it, make sure that the ROM with which it was born is installed in the phone (same region).
