• Sxmo (Wayland/Sway) Please post the output of sxmo_version.sh
• Other: console (but pulled in bananui)

Which init system are you using?

How did you get postmarketOS image?

• from https://images.postmarketos.org
• I built it using pmbootstrap
• It was preinstalled on my device

Additional information

Building an image for the device using pmbootstrap and flashing on an SD card and then following the instructions at

https://wiki.postmarketos.org/wiki/Nokia_2780_Flip_(nokia-weeknd)

wouldn't give me a booting device. I then used

git clone https://git.abscue.de/affe_null/weeknd-toolbox.git
cd weeknd-toolbox
./build.sh
./flash.sh

to verify that the phone can boot a recovery image just fine. This got me a working weeknd-toolbox.

I then did

# Break the weeknd-toolbox
dd if=/dev/zero of=boot.img count=10000; 
dd if=boot.img of=lk2nd.img seek=512 bs=1024
./flash.sh

to get a lk2nd only onto the device that wouldn't boot into the toolbox right away. This allows one to enter lk2nd's fastboot with the vol-up, wait, vol-up dance from now on.

One can then create a bootable image by combining the kernel from weeknd-toolbox with the initramfs from pmOS:

python3 mkbootimg.py -o franken.img \
  --kernel Image.gz-dtb \
  --ramdisk /path/to/pmbootstrap/chroot_rootfs_nokia-weeknd/boot/initramfs \
  --cmdline 'earlycon console=tty1 pmos_boot_uuid=2c300474-3991-408a-8465-a10e8da7056c pmos_root_uuid=38ecc4a9-b344-4a11-abe3-bc36de3d4484 pmos_rootfsopts=defaults'

This can then be booted by switching lk2nd to fastboot mode (as described above) and then running:

fastboot boot franken.img

and one can then ssh into the device via ssh which boots up to the bananui (which currently doesn't work (https://git.abscue.de/obp/bananui/shell/-/issues/1, https://gitlab.gnome.org/World/Phosh/phoc/-/issues/395) but that is fixable.

Wanted to leave that here in case someone wants to pick that up to get the device into shape again which.
