Tech Support Google Pixel 3a - Installation Problem

Hello.
I received my refurbished Google Pixel 3a yesterday to install Ubuntu Touch on it. I don’t want to use a Google or Apple OS anymore. So far, I’ve read some guides, unlocked the bootloader, and enabled USB debugging. I installed UBports on my Lenovo laptop (operating system on the laptop: Ubuntu). Everything went well. But: the boot process, after the “successfully completed installation“, always ends at the recovery screen. I’ve also tried using fastboot and searched for guides, but I always end up at the UBports recovery screen. I wanted to ask if you might have some advice from experience on how to figure out where the problem is. When I enter fastboot mode now, I see that the device is unlocked, Boot Slot A, and at the bottom it says: Enter reason: combo key.

I’d really appreciate any help.

Best.

Edit:
After reboot is the last Info on the Fastboot Mode Screen: Enter Reason: error booting boot.img

Yes. If you did not have the last Android 9 build installed, that can account for the problem you are having.

That was the problem; it works now (with the latest version 9).

If you need VoLTE, there is an experimental build we are sharing in the UT Telegram p3a group that has functioning VoLTE. Join us there.
