Flashing
Flashing requires wiping some partitions to make sure the bootloader does not mess up the mainline kernel devicetree.
fastboot set_active b fastboot erase vendor_boot fastboot erase dtbo
Afterwards, you can flash the device as usual using pmbootstrap's flasher utilities. If your rootfs is under 2GB in size, you can flash to the cust
partition which is only used by MIUI, otherwise super
is recommended (make sure you have a backup or a super_empty.img
to restore Android if you intend to go back).
