You flash the older version again.
Hopefully, you won't need to format data but you can backup, just in case.

Downgrading is not heavily documented, but as far as I know :

Cache/Dalvik won't hurt if you do them.
Edit : Poney70 said format data is required

And as discussed, hopefully you won't need to format data, but be ready if you bootloop or something.
So there is still a chance that im goin to get bootloop if i try to go back to old version?

*** Backup things before ***

Install previous Stable ROM then use "Format Data" button in "Wipe" menu. Reboot your device and wait. ;)

But you can try to downgrade to 12.0.8.0 without formatting your data. :)

Question: What's the Android security patch date of 12.0.9.0 (in phone's settings => "Security")?

Okay, install 12.0.8.0 if you want to try then reboot your device (so without using "Format Data" button in TWRP). ;)
Does 12.0.8.0 still has the reboot issue on poco m3 or not? (Sorry for asking so kuch question)
