Flashing instructions (Credits phhusson and Akito)

  • Make sure to have the latest platform-tools installed.

  • Install Xiaomi OEM Android driver(Google's newest ones don't work under fastbootd) at https://developer.android.com/studio/run/oem-usb#Drivers: delete all .cat file, disable Windows driver signature enforcement (since the driver is much too old), right click on the .inf file and click install. Ignore the warning and continue.

  • Retrive vbmeta.img and recovery.img from official packages.

  • Reboot to bootloader:

adb reboot bootloader
  • Flash vbmeta with
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
  • Flash stock recovery if using wzsx150's unofficial TWRP
fastboot flash recovery recovery.img
  • Reboot to fastbootd
fastboot reboot fastboot
  • Check device status with fastboot devices. Linux may run into problem with udev, and I wrote
$ cat /etc/udev/rules.d/20-k30.rules
SUBSYSTEM=="usb", ATTR{idVendor}=="0000", MODE="0666", GROUP="plugdev"

and reboot to fix the permission issue. Windows users may need to install driver manually.

  • Flash you downloaded gsi system.img with
fastboot flash system gsi-system.img

If system partition doesn't exist, go back to "Reboot to fastbootd".

  • Wipe data
fastboot -w
  • Reboot phone
fastboot reboot
  • Enjoy!
