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