How to enter flash mode

  • Download mode: While the device is turned off, hold Power + Home + Volume Down, and confirm the action by pressing Volume Up thereafter.
  • Recovery mode: While the device is turned off, hold Power + Home + Volume Up.

Installation

pmbootstrap init # Choose samsung-logan
pmbootstrap install
# Boot into download mode before running the command below
pmbootstrap flasher flash_rootfs
# Boot into download mode again
pmbootstrap flasher flash_kernel

Hardware Acceleration

Note Note: This is not fully tested and could not work.
  1. Open aports/device/testing/device-samsung-logan/APKBUILD in a text editor and add mesa-egl to the depends
  2. Rebuild the device package: pmbootstrap build device-samsung-logan --force
  3. Run pmbootstrap install --fde

However, the image will be much bigger than the system partition, so you will need to either flash it to another partition or an SD card.

USB Internet

See USB Internet.

Display

If your device is stuck on the postmarketOS splash screen on startup (or the screen is black) and you are using LightDM, connect to your phone via SSH and run this command:

loginctl show-seat seat0

If CanGraphical is no or 0, open the LightDM config in a text editor:

sudo vi /etc/lightdm/lightdm.conf

Find the line where it says #logind-check-graphical=true and replace it with logind-check-graphical=false. Restart the device and it now should work.
