<![CDATA[reflash after installing Ubuntu Touch]]>I succesfully installed Ubuntu Touch and i'm not very satisfied with waydroid functionality. Anyway, i want to try postmarket OS and, eventually, return to Android, not sure I will see.
But I,m stucked:

  • UBports installer(0.10.0) (I, ve updated it, first I, ve used a beta version) says: "The device halium_arm64 is not supported"
    and
  • flash_fp4_factory.sh are not seeing the device: No "Fairphone 4 found in fastboot mode."

I think I am in the fastboot mode : "the bootloader is unlocked and ..."

Boot into fastboot mode to solve it.

That is the normal booting process with unlocked bootloader, not in fastboot mode
To enter fastboot mode:

  1. Make sure your Fairphone 4 is fully powered off
  2. Keep holding volume down and plug in USB-C cable to the charger/computer
  3. You're now in fastboot mode
