Please advise how to proceed: got a G5 850 with just TWRP — no system!

[[email protected]]

Current state:

• TWRP is version 3.2.1-0 — If I want to shut-off, device restarts with:
• g.co/ABH error: "lock the bootloader" — how do I get rid of this nuissance?
• Fastboot displays with tiny font (due to the high screen resolution I guess) — but is fully responsive to commands from my notebook

Which system would you suggest? Does LinageOS support the camera-features?

Thank you for all assistance!

Any updates?

Warning message is normal with unlocked bootloader. For system, you can follow lineage flashing procedures from whichever verion (14, 15, 16, etc.) you're wanting. Camera features work pretty good with Open Camera App. I'm currently using the Fulmics Rom, but I tend to try others over time.

LineageOS 17 up and running

Any updates?

Yes, I succeeded in installing Lineage. It appears, that the device might have a hardware problem: the switch/fingerprint reader seems to be little responsive.
Need to figure that out now…

The fingerprint sensor might just be faulty, as it is connected to the motherboard with around 10 springs that may be damaged when the phone is opened and closed.
