What works

  • compiling kernel
  • booting
  • ssh connection
  • screen output
  • touch screen

How to enter flash mode

  • Recovery: With the device powered off, hold Home + Volume Up + Power.

Unlocking

In Android go to settings -> System -> About phone and tap the build number 7 times. Then go to settings -> system -> developer options and enable OEM unlocking

Installation

installed system directly on device:

  • pmbootstrap install --no-fde
  • pmbootstrap flasher flash_
  • pmbootstrap flasher flash_kernel # after this command finishes, device reboots and pmOS starts :-)
  • had to follow USB_Network#Assigning_an_IP_address as IP to host computer was not automatically assigned:
    • sudo ip link set TheNetDevName address 12:12:12:12:12:12
    • sudo ip address add dev TheNetDevName 172.16.42.2/24
    • sudo dhclient -v TheNetDevName
  • ssh -p 22 user@172.16.42.1

Developer Notes
