Update from stable 12.0.5.0 to last Weekly

[tasmya]

Good morning,

I'd like to update my firmware from stable to weekly, but sadly every time I try I get stuck into a TWRP bootloop. The only solution to solve it is to flash back stable.
I tried wiping data, but that doesn't solve the issue.
On my old Mi5, the procedure I was doing was the same, and I never encountered any issue.
What should I try?

You did a wipe data or a format?

Wipe, format wipes the sd card too

Take out the card before you wipe maybe is a solution?

Read this to know why, after "Stable to Weekly" dirty flashing, your device may doesn't boot to system => https://xiaomi.eu/community/threads/flash-stable-to-weekly.56082/post-546911

Thanks, is it the same for mi9? Where could the fingerprint be found?

Anyway, I made a full backup and formatted data. So I was able to do that

Yes, and you can take fingerprint build and security patch date infos from Stable ROM in /system/build.prop file. It's the easiest way.
