What works
- Compiling the latest lineageos kernel with some patches applied
- Booting a graphical screen when installing PostmarketOS as recovery zip in TWRP.
- Network connection via USB and SSH access
- Screen works
- Brightness can be changed by echoing a value to /sys/class/backlight/panel/device/backlight as root
- Wifi with properietary blobs
- Touch screen
- Wayland
- X11
- Keyboard and mouse with USB OTG adapter (Hotplug works)
- Initramfs password entry for full disk encryption
What does not work
- Touch screen requires a reboot to work in some rare cases
- 3D acceleration
- Wayland default on screen keyboard
How to enter flash mode
Press volume down + the power button to enter Download Mode. It is now possible to use Heimdall for flashing.
Installation
- Install pmbootstrap
pmbootstrap init
pmbootstrap install
- Put your S4 in Download Mode (Volume Down + Power) and connect it with USB
pmbootstrap flasher flash_kernel
- After the kernel is flashed, the device will reboot. Hold the volume down button while it boots up to re-enter Download Mode
pmbootstrap flasher flash_rootfs
Wifi
Once the device has been successfully initialized, enable it:
$ sudo ip link set wlan0 up
Configure wpa_supplicant (only necessary on encrypted networks):
$ wpa_passphrase $YOUR_SSID | sudo tee /etc/wpa_supplicant/wlan0.conf <enter passphrase here and press Enter>
Connect to network using wpa_supplicant:
$ sudo wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/wlan0.conf
If your network uses DHCP, start the DHCP client:
$ sudo udhcpc -i wlan0

Main board UART
To simplify getting logs when doing development, it can be useful to connect to UART directly on the main board. UART (and supposedly JTAG) can be found close to the battery connector, among in 11 pads at the edge of the PCB. TX (from phone's perspective) is second pad from the top, and RX the third one. The device uses 1.8 V signal strength.

SPH-L720T
- SXMO works with touch.
- USB networking does not work properly.
- ping works early on in boot, but then it stops working, and SSH never works.
- Other interfaces I tried, Xfce4 and MATE, did not work.
- Wayland is untested.
- USB OTG keyboard works, other devices untested.
