Installation
The mainline kernel can only be booted through U-Boot, not directly with the Samsung bootloader. U-Boot is installed as intermediate bootloader on the boot partition, so it does not replace the Samsung bootloader entirely. pmbootstrap can only support one bootloader configuration at the moment, which is why U-Boot is also recommended when installing the downstream kernel.

Boot into Download Mode using +  +  and follow follow the the NovaThor U8500 U-Boot installation instructions to install U-Boot.

Finally, follow the Installation guide. You should install the rootfs to the SD-Card, because the internal Storage is pretty limited.

Mainline
Working (v5.18.0-rc1):
 * Display including full brightness control
 * GPU (Mali-400 MP using Lima)
 * Touchscreen
 * WiFi
 * Bluetooth (partial - at least on my device scanning for other devices works but it keeps disconnecting when connecting to other devices; not sure why)
 * IMU (Accelerometer + Gyroscope)
 * USB
 * Flashlight (turn on/off in Phosh drop down menu)
 * Battery - charging and battery indicator works

Not working:
 * Audio
 * Camera
 * Other

Bluetooth
Bluetooth does not have any Bluetooth device address (bdaddr or "MAC address") set after boot at the moment. To make Bluetooth work, you need to manually configure one:


 * 1) apk add bluez-btmgmt
 * 2) btmgmt public-addr

where  is a MAC address like.

The Bluetooth controller should then show up in :

$ bluetoothctl
 * 1) apk add bluez
 * 2) rc-service bluetooth start

You can e.g scan for devices:

[bluetooth]# show [bluetooth]# power on [bluetooth]# advertise on [bluetooth]# system-alias golden [bluetooth]# scan on

Experience
Downstream: The best user interface to install is XFCE4. Other ones do lag, or just don't respond. Especially KDE Plasma.

Mainline: Plasma Mobile and Phosh should work okay.

DSI Scaling Error in Phosh
If you are running phosh, and the scaling is wrong so that you cannot type in the password to unlock the initial login screen, this can be fixed by changing this file  like this:

[output:DSI-1] scale = 1
