How to enter flash mode

Starting with the device powered off:

  • Download mode: power + volume down
  • Recovery mode: power + volume up

Installation

Using pmbootstrap

Heimdall flashing seems to be broken, so Installation_from_recovery_mode is used.

Install TWRP recovery from twrp.me.

By default pmbootstrap install --android-recovery-zip installs on the SYSTEM partition, which is very small. pmbootstrap install --android-recovery-zip --recovery-install-partition=USERDATA may be preferred.

Note If you install to USERDATA, make sure to unmount data partition from TWRP before flashing, otherwise it will fail
