Hi everyone, I am thinking to downgrade from MIUI12.5.5 to 12.0.1 and both are android 11 based.
1.Will xiaomi anti-rollback policy bother me ?
2.Should I erase some lines of code from flash_all.batch file which are used to verify the version of OS?
CAN SOMEONE GUIDE ME :)

Btw how can I use miflash to flash an mtk device. I came to know that miflash only works with snapdragon devices.

Miflash works with Mediatek:
