Hi,

I'd like to flash the Stable 12.5 (link) on my Xiaomi Mi 9T Pro phone which is currently on the MIUI 12.5.1 Stable ROM 12.5.1.0(RFKEUXM).
First question: Is a data wipe / format necessary to flash the rom, or could it be done by a "dirty" upgrade?
Second: The list in the post states that for raphael phones (and thus Mi 9T Pro) the means of flashing is recovery, how exactly does flashing with recovery go?
Do I first unlock the bootloader, then install TWRP through which the ROM can be flashed?

Thanks in advance!
