@sven No such trickery should be needed on the 22, did you have issues using Waydroid Helper from OpenStore? Perhaps join https://t.me/waydroidonut to discuss your issue further

The replacement screen is different model from the original that shipped with the device; I believe the originals all ran out so only the compatible-with-Android 12 panels are provided, which means Ubuntu Touch side also has to be rebased to Halium 12 (from Halium 11). I've started this in https://gitlab.com/deathmist/volla-mimameid/-/commits/halium-12/ but it's not ready to push as an update yet due to non-functional Wi-Fi for example.

@myrtaki If you're more technical and won't mind taking the very work in progress build for a ride you could try the following:

1. Enter bootloader mode on the Volla 22 (which could be tricky entirely blind but doable when checking fastboot devices and holding power button otherwise to retry; on Linux computers dmesg -w output may also be handy to better see the boot status of the device)
2. Download https://ota.volla.tech/volla-12.1-20230701-stable-mimameid-signed.zip and unpack payload.bin using https://pypi.org/project/payload-dumper/ or similar
3. fastboot flash most *.img files to their respective partitions excluding vbmeta ones, boot, product, system and vendor (we'll come back to vendor later)
4. Download and unzip https://gitlab.com/deathmist/volla-mimameid/-/jobs/4610670029/artifacts/download?file_type=archive
5. Flash the boot.img extracted from the previous volla-mimameid artifact archive
6. Reboot to recovery (at this point the display should work properly already)
7. Enter fastbootd mode
8. Flash ubuntu.img to system partition
9. Flash previously extracted (from payload.bin) vendor.img to vendor partition
10. Reboot and hopefully have all your Ubuntu Touch data intact just now running on top of Halium 12

I can perhaps publish updates here as more of the current issues with newer builds (will have to manually reflash ubuntu.img once available) are fixed as it gets closer to becoming the new official build available simply through UBports installer.

@nicolasrull I believe you ended up getting this solved as reported on https://t.me/volla_dev/10340, correct?

This was originally caused by picking the wrong device (Volla Phone 22) in the UBports installer including with bootstrap option selected which overwrote the bootloader of the X23 making even access to fastboot not possible; the only means to recovery was SP flash tool in this case.

Waydroid on latest X23 development/RC channel builds now works but there's some big caveats to using it right now, see https://gitlab.com/ubports/porting/reference-device-ports/halium12/volla-x23/volla-vidofnir/-/issues/1 for more details

@PublicLewdness Did this get resolved yet? You could use the recovery mode along with https://github.com/ubports/installer-configs/pull/240 for now and launching UBports installer from command line with -f argument pointing to the saved vidofnir.yml installer config file.
