For a TL;DR
The omnia won’t boot anymore as it’s just resetting after the message “Starting Kernel”
I tried:
- Return to last snapshot
- Reflash using medkit file (with ext4 and fat formatted USB)
- Create a bootable usb
All of the above didn’t work for me and the device still isn’t booting.
I have UART access to the device and am up to try anything to get it working.
The problems started when I attempted an update.
After the update the omnia didn;t boot anymore and UART access told me it couldn’t read the btrfs volume.
It looked like the u-boot environment did not have a kernel module for the btrfs filesystem.
After this I used the medkit usb method to flash the device an have been in the situation described above ever since.
