Flash instructions:

  1. Backup data with TWRP ONLY for Oreo 8.0 firmwares or other backup tool: adb reboot recovery (reboots into your recovery and stock recovery if you haven't installed a custom recovery)

  2. Reboot to eRecovery

  3. Wipe (factory reset including data) with stock Recovery (not eRecovery; you will need to reflash a stock recovery through fastboot) (TWRP wipe doesn't currently work)

3.1 Wipe (factory reset) works in this TWRP-Mod for Huawei/Honor only with EMUI 9 and in TWRP-Mod for Huawei/Honor only with EMUI 9.1

Direct download links: TWRP-Mod for Huawei/Honor only with EMUI 9 and TWRP-Mod for Huawei/Honor only with EMUI 9.1

Hardware commands - done with device turned off

Need to connect the computer:

  • Fastboot mode: long press the volume down key + power button.

  • eRecovery mode: long press the volume up key + power button.

Do not need to connect the computer:

  • Recovery mode: long press the volume up key + power button.

  • Upgrade mode: long press the volume up key + volume down key + power button.

Additional infos:

  • EMUI 8.0 & 8.1 use ARM64 A Roms.

  • EMUI 9.0 & 9.1 use ARM64 AB ROMs due to system as root (if in doubt check here).

  • GSIs tested and working well: OpenKirin

  • Ported stock Camera exists and mostly work, keeping original quality.

  • Brightness stuck at 40%, both in settings and real life.
    May be not an issue anymore, started from v19 (2018-06-03), now using v23 (2018-08-07) and never been able to reproduce.

  • On-screen navigation buttons can be hidden by adding qemu.hw.mainkeys=1 to /system/build.prop

  • Home button behavior can be set to default (to behave as on EMUI) by replacing /system/phh/huawei/fingerprint.kl content with the following line: key 174 HOME
