It works , thaaaanks alot"Format Data" (in "Wipe" menu => "Format Data" button) and NOT wipe /data, to do a clean install.
Mi 9twhich phone did you do this on? I have MI 10 and also wnat to downgrade, but im am very concerned about anti-rollback-protection combined with an older android version...
Thank you For fast answer! But Mi 9t ist one year older and im not quite Sure If there May ne a difference to the Mi 10... Im am in fear of hardbricking my device... Maybe a real pro Like Igor or so knows the answer...? )Mi 9t
There shouldn't be any risk from downgrading on any of these devices, ARB (anti-rollback) protection was only ever relevant for Mi 6X, Mi Max 3, Redmi Note 5 Pro and Redmi 6 Pro, which are way older than what you have.Thank you For fast answer!

You'll have to "Format Data", as said above, after flashing whichever ROM you're downgrading to.
Run this command with fastboot:Thank you For your answer!!! Sounds quite promising... Even though For example i cannot downgrade to official MIUI 11 Rom via miflash there it says that it is Not possible due to anti-rollback-protection. And it is a different Android Version so i was quite unsure... But If you say that i will Trust you ^^
So i will wipe Cache, and so on in twrp.
Then i will Install MIUI 11 Zip, then i will Format Data and then reboot and Hope that it works... Correct?
fastboot getvar anti
Yes i get 1, but For example i Checked all official Mi 10 Fastboot Roms for MIUI 11 and they all have anti Rollback Protection 0, so i cant flash Them. That Made me quite unsure about that...Run this command with fastboot:
If the result is "1", you'll be OK.Code:fastboot getvar anti
You should be fine.Yes i get 1, but For example i Checked all official Mi 10 Fastboot Roms for MIUI 11 and they all have anti Rollback Protection 0, so i cant flash Them. That Made me quite unsure about that...
I will Just try it now... Lets Hope that everything goes Well...You should be fine.
