User Interfaces

Gnome starts but is pretty unusable
Phosh/Plasma Mobile do not work (require mainline)
Xfce4 works

Installation

pmbootstrap init
- User interface: xfce4
- Extra packages: matchbox-keyboard[1] or corekeyboard [2] to get an on-screen keyboard
pmbootstrap install --android-recovery-zip
pmbootstrap flasher --method=adb sideload

What works

Flashing rootfs and kernel via TWRP
Screen
Touchscreen
WiFi

Attention: latest edge won't come up with ssh cause of missing /etc/network/interfaces do a "pmbootstrap chroot -r" create and edit the missing interface file and add: auto lo iface lo inet loopback

After that do a install as usual and network comes up with ssh

What doesn't work

Audio
USB-OTG
charging sdl

Additional notes

ADB sideload stops at 50%, but it actually succeeds.
The power button instantly shuts down the entire system
LightDM Hangs after a while but can be restarted from USB/SSH
Some audio devices do show up, but they don't actually work.

How atipls made wifi work

How atipls made wifi work (with a bit of confusing detours). Inspired by the (sort of) helpful How_bonsaiblue_made_wifi_work.

Since the kernel provided by Samsung has built-in support for the BCM4343, enabling it was enough to get wlan0 to show up.
- I actually have tried loading it as a kernel module, which ended up with horrible messages like no wifi platform data, skip and DHD wifi platform data is required for Android build
Grab nvram_mfg.txt and bcmdhd_mfg.bin from /etc/wifi from either a stock install or an unofficial lineageos port.
- I have also tried firmware-aosp-broadcom-wlan, but the firmware seems to be newer than wanted thus either not loading or straight up soft bricking the OS.
Bring the interface up: $ ip link set wlan0 up
Use XFCE4's menu or nmtui to connect to a wifi network.

Useful key combinations

home + volume up + power: flash mode (TWRP)
home + volume down + power: reboot
