- Press and hold + + simultaneously while device is powered off for recovery mode.
What works
- Phone boots
- Touchscreen
- Framebuffer with msm-fb-refresher
- Phone is charging and battery status is working
- Volume and power buttons on gnome
- Weston, GNOME, Sxmo, Xfce4, MATE
- Screen brightness changing on (at least) mate and xfce (see Screen brightness)
- Wifi with firmware package
- Mainline (WIP)
Installation
2. Unlock the bootloader and flash twrp
3. Setup pmbootstrap:
$ pmbootstrap init
...
Vendor [samsung]: samsung <- enter this
Device codename [dream]: dream <- enter this
Available kernels (2):
* dreamlte: Kernel for the Samsung Galaxy S8
* dream2lte: Kernel for the Samsung Galaxy S8+
Kernel [dreamlte]: dreamlte <- choose your device model
User interface [weston]: <- choose your preferred UI
...
4. Create a twrp flashable .zip
$ pmbootstrap install --android-recovery-zip --recovery-install-partition=data
5. Installation_from_recovery_mode
Wifi
To connect to a wifi the same steps as for the Medion Lifetab S9714 (medion-kai) works:
1. Verify that the wlan0 interface exists
$ ip link
2. Turn on wifi
$ nmcli radio wifi on
3. List available wifis
$ nmcli device wifi list
4. Connect to your wifi
$ nmcli device wifi connect "$SSID" password "$PASSWORD"
5. Verify that you have been given an ip address on the wlan0, or swlan0, interface
$ ip a
Screen brightness
On mate the screen brightness can be changed with:
echo a value between 0 and 36600
# echo 18300 > /sys/devices/platform/panel_drv@001/backlight/panel/brightness
On xfce you can run set the brightness with xfpm-power-backlight-helper:
set a value between 0 and 100
# pkexec xfpm-power-backlight-helper --set-brightness 50
USB OTG keyboard
Connecting a USB keyboard does not work (tested on xfce). The keyboard shows up in dmesg and lsusb correctly, and
# libinput list-devices
shows it. However,
$ xinput list
does not show it, and it is not recognised in /var/log/Xorg.log.
elogind-daemon reports something like
Watching system buttons on /dev/input/event8 (keyboard name)
in dmesg when the keyboard is connected. Maybe elogind is "hogging" the keyboard? Patching elogind to ignore the device does not make a difference though, X still does not recognise the keyboard.

$ sudo apk add linux-tools-iio
$ lsiio

Mainline
It boots! However only very limited hardware has support for now.
