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-logands
pmbootstrap install --android-recovery-zip  
pmbootstrap export
# Find installation .zip in '/tmp/postmarketOS-export' folder.
# Put .zip on SD card. 
# Boot into recovery mode
# Install .zip using recovery tool like CWM or TWRP.

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.
