How to enter flash mode

On boot press and hold the Volume Down button. If your device is already powered off, press and hold the Volume Down and Power buttons simultaneously until you get to the "FASTBOOT" screen.

Installation

Install fastboot on your host system and run the following commands:

$ pmbootstrap init
$ pmbootstrap install
# fastboot erase dtbo
$ pmbootstrap flasher flash_vbmeta
$ pmbootstrap flasher flash_rootfs
$ pmbootstrap flasher flash_kernel
# fastboot reboot

Not merged features

Those features are already working but not yet merged into postmarketOS / mainline linux:

Touchscreen
USB OTG
Display and GPU

Display

The device as of now can only run a simple framebuffer.

Modem

No support on the platform as of now, shouldn't be too hard to implement since it's the same modem in the SDM630, SDM636, SDM660 and SDM670.
