Ok, I decided to Power Off / Power On the device after night.
C2 booted to 5.0.0.29
I tried to update C2 again but this time with USB charger connected. This time update went fine
Now I’m on 5.0.0.43. I suspect that connecting USB-C cable during the update introduces some issues.

I think they use a mixture of O2 (EPlus) for 4G and their own 5G network (which cannot be used by the C2).
I second that, its hard to use alarms at default volume, but it was always the case. I didn’t knew about the patch so my workaround was to use custom alarm sound with gradually increasing volume. Give it a try If you don’t care about the exact sound.
Instructions for updating the bootloader (if needed) and flashing the C2 with the fastboot flasher.

Update went well.
Backlight is still very weak on reboot for installation, so keypad is barely visible (for encryption key).
I just did the upgrade to 5.0.0.43 before traveling in Europe. Updating and backup to sdcard went without issues. Now the C2 feels mature except the video recording (I use Aperture Android app a replacement for now) all other issues are solved now. MicroG is kinda working but some apps still complain about Google Play missing but my banking app is usable. Thanks for getting the 4G VoLTE call receiving to function! Also, I amazed how fast the C2 is getting mobile network connection after disabling flight mode. Thank you Jollyboys for the hard work and happy holidays!
