How to enter flash mode
With device powered off, hold [VOLUME +] and plug USB cable in. Device's LED will turn blue, meaning it has entered fastboot mode.
Force power off
Hold [VOLUME +] and power button for several seconds.
Kernel boots up to the point where the phone displays "CHARGING MODE: error starting charging-sdl". It has been tested with firmware 47.2.A.10.107.
Unfortunately USB networking does not work at the moment, so further investigation is difficult.
The simplest method to see dmesg messages after a freeze during boot up:
- boot a postmarketOS image (pmbootstrap flasher boot)
- disconnect the USB cable as soon as the boot process starts (e.g. when Sony logo appears)
- keep holding [VOLUME -] to start the recovery
- in recovery, start terminal and run 'cat /sys/fs/pstore/console-ramoops'
