TODO

Installation

  1. Update to latest vendor (via OTA or fastboot package if bootloader is unlocked)
  2. Unlock bootloader (officially or via mtkclient)
  3. Recommended: backup sensitive partitions (in case you inadvertently wipe IMEI)
    • nvcfg
    • nvdata
    • nvram
    • persist
    • protect_f
    • protect_s
  4. Follow PHH flashing guide (see telegram note #flash)

Uninstallation / Back to stock MIUI

From a working device using fastboot

  1. Download a full ROM package, usually marked as Fastboot, from Xiaomi Firmware Updater
  2. Verify .tgz archive hash (MD5 hash is provided on download page)
  3. Open or extract .tar from .tgz archive
  4. Extract ROM files from .tar archive to disk
  5. Connect your device in fastboot mode (verify using fastboot devices)
  6. Execute flash_all script (or flash_all_lock if you want to relock bootloader)
    • .bat for windows
    • .sh for linux
  7. Device should reboot automatically, if not and no error was displayed try fastboot reboot
  8. Device should boot on MIUI (on first boot splash logo can de displayed few minutes)

Unbricking

If something went terribly wrong and you need to completely reset the device here are some recommendations:

  1. Charge the battery by leaving the phone plugged for a while (even in bootloop)
  2. Try to hard restart the device by holding POWER for ~10 seconds
  3. Try to make a userdata backup using mtkclient BROM exploit
  4. Try to boot into fastboot or recovery mode via key combo (or by plugging the phone and only with volume key if it bootloops)
    • recovery: POWER + VOLUME UP
    • fastboot: POWER + VOLUME DOWN
  5. From recovery: Wipe Data !! this will format userdata and erase all your data from the phone !!
  6. From fastboot:
    • dirty flash the same system image (data should be preserved)
    • format data: fastboot -w
    • clean flash a system image
  7. Use SP Flash Tool and bypass utility: see postmarketOS unbrick guide
