Samsung Galaxy S Duos (samsung-s7562)

From postmarketOS


Note This device is still running on armhf, although the processor supports armv7. If you own it, change it and test it that way.


Icon WARNING: This device is not recommended for future use with postmarketOS due to its armhf architecture. Alpine Linux (the distribution that postmarketOS extends) has been considering dropping it.
In some cases, the processor of the device may support the armv7 architecture. If so, you can modify the device package and change the architecture accordingly.

What works

  • Compilation of kernel, system and initramfs
  • pmOS starts up if a pre-compiled kernel (from the original boot.img) is used, along with the newly built initramfs and system image. Telnet, decrypt filesystem, and ssh (partially) works

What does not work

  • pmOS does not boot with the newly built kernel. it only works if a pre-built factory kernel is used
  • ssh fails with a 'cannot create channel 0' error, which can be bypassed with ssh user@<ip> '/bin/sh'. With this, no prompt is shown (i.e. no "$" or "%"), but commands can be typed and executed and the results are displayed
  • No graphics are displayed on the screen, weston fails with Failed to open frame buffer device ‘/dev/fb0’: No such file or directory
