Das Max3 hat ja eine Rollback-Protection. Was bedeutet das genau? Gilt das für alle ROMs oder nur für MIUI?

[Guide] How to check the Anti Value of your Rom or a Rom that you want to install
For some strange reason, the "fastboot getvar Anti" doesnt work on Mi Max 3. it might say "variable not found" or "getvar failed / not found"
this leads to people bricking their devices thinking that they dont have AntiRollback.
go to line 0x1480
6. you will see something like "0.00000X000" and above it will be "californial"
7. if X is 1, that means that this rom doesnt have antirollback meaning that if you dont have arb, you can downgrade to that version or install it without getting the ARB, but if you have ARB you cant install it or you will brick your device.
if X is 4, that means that this rom has antirollback meaning that if you dont have arb, you will get it when you install this rom, and for ARB users as long as this is a higher version than the one you have currently installed on your device you can install it safely without bricking your device

- If the current rollback index is less than the rollback index in the images to be flashed, then the images will be flashed and the current rollback index will be incremented to match the new rollback index.
- If the current rollback index is equal to the rollback index in the images to be flashed, then the images will be flashed and the rollback index won’t change.
- If the current rollback index is greater than the rollback index in the images to be flashed, then the images will be rejected if you’re flashing via fastboot or Mi Flash. (TWRP does not check the rollback indices before flashing, which is why nearly all bricks were the result of downgrading via TWRP.)
