Samsung Galaxy S4 Mini dual sim (samsung-serranodsdd)

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.

Current main issues

  • Device doesn't automatically give itself mac address, ip, etc - you need to configure the network manually (have to set mac address of usb0 inside initfs hook)
  • Device reboots immediately after flasher usage - not a postmarketOS issue, it is samsung's fault, affects all samsungs' phones

(would have to edit postmarketOS's flasher to use heimdall no reboot and heimdall resume features)

  • Charging seems to work, but there's no indication of it actually happening

Current work

samsung-serranodsdd:~$ exec /usr/bin/plasmashell -p org.kde.plasma.phone Failed to create wl_display (No such file or directory) qt.qpa.plugin: Could not load the Qt platform plugin "wayland" in "" even though it was found. This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: wayland-org.kde.kwin.qpa, eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, xcb.

    • nothing runs by itself; scripting needed
    • udev rules copied from halium don't work due to user mismatches; this needs figuring out

How to enter flash mode

  • Hold home + volume down when booting the device

Installation

  • pmbootstrap flasher flash_kernel and
  • pmbootstrap flasher flash_rootfs is working flawlessly
