Flashing instructions (similar to K30 Pro, no working TWRP currently available for this model)

(Unlock through Xiaomi MI Unlock tool first, takes days 😞)

Reboot to bootloader:

adb reboot bootloader

Flash vbmeta with

fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img

Reboot to fastbootd

fastboot reboot fastboot

Flash system with

fastboot flash system system.img

Wipe data

fastboot -w

Reboot phone

fastboot reboot

Another way to flash GSI on cezanne

  • Download GSI-packer-tools and upzip it

  • Prepare a stock MIUI firmware(Android11 must)

  • Rename GSI to gsi.img, then copy the stock MIUI and it to the "input" directory in GSI-packer-tools

  • Click build.bat and choose '2'

  • Wait a minute and you will get a gsi_rom.zip in "output" directory

  • Flash it via twrp, wipe data and disabled-vbmeta.zip is a must

  • Magisk 23+ if you need, flash it before disabled-vbmeta.zip

Important note about recovery

I had difficulties reflashing the stock MIUI rom with Mi Flash Tool, and other MTK flash tools as this processor is unsupported.

(For early builds like AOSP 10.0) To reflash stock MIUI use the V12.0.8.0 Recovery/Fastboot ROM link

(For newer builds) To reflash stock MIUI use the V12.5.7.0 Recovery/Fastboot ROM link, unzip and run the flash_all script for your operating system while your device is in fastboot mode.
