I installed an unofficial build of Resurrection Remix 7.1.2 on Meizu Pro 5 (M86) with TWRP 3.0.2. Out of curiosity I then enabled encryption with the thought that even if I don't like it and cannot reverse, I should be able to rollback the previous system backup via TWRP. There is no data to care about, but still I want to be able to install on the phone whatever I want.

I was wrong. TWRP won't boot anymore. Its boot screen appears but just flashes every 5 seconds or so.

I then tried a few things:

  • Factory reset from the Settings. I can reach the "Erase Everything" button but it does nothing;
  • Factory reset from ADB:
    • recovery --wipe_data says /system/bin/sh: recovery: not found
    • wipe data says /system/bin/sh: wipe: not found
    • After adb reboot bootloader I have no luck running fastboot devices: it outputs nothing
  • Attempting to flash a newer version of TWRP from TWRP App (image for Meizu Note 6; there is none for my device) but it complains that the device is not rooted (the developer settings only allow root via ADB).

So is there a way to just wipe the device and re-install something on it?

  • recovery --wipe_data is supposed to be run when you are in recovery mode. wipe data is not a valid command at all. You can write --wipe_data to /cache/recovery/command file and then reboot to recovery mode using adb reboot recovery command. If recovery mode isn't booting, boot into bootloader mode and boot recovery from there. – Irfan Latif Sep 15 '19 at 07:12
