problem booting Pixel 3a

[clUB28]

I tried flashing a Google Pixel 3a yesterday to use ubuntu touch and now I am stuck in fastboot (details below). I cannot enter recovery mode (I don't know why). I trie contacting google support, that didn't work, I cannot find any helpful resources for my issue.

I really want to give Ubuntu Touch a try, I just need to somehow get back up on the horse.

I don't know if this is the right place to put this as it is more of a hardware issue? But it started with Ubuntu touch.

Details:

After flashing ubuntu touch it loaded for a while and then it showed the google logo (strange?). I now have the options of fastboot or booting (which never properly loads anything). I cannot enter recovery, although sometimes I can manage to get to a little guy fallen over saying "no command" which happens in the same way that recovery mode starts from fastboot. ADB does not work. I am running linux and dont have access to windows right now (I guess a VM but I have had my own issues with usb not connecting, so its kind of not an option imo). I have tried flashing the original android 9 again, but that doesnt seem to work?

@clUB28 Ok, I will try and point you in the direction of sorting this out.

Try this first. Open a terminal where your fastboot and adb drivers are, have the device in fastboot mode (the bootloader).
The Pixel 3a has slots, slot a and slot b. In fastboot try this command:

fastboot --set-active=a
Then boot the device.
If that fails, try:

fastboot --set-active=b
Then boot the device.

If that fails, reinstall Android and start again. I have done the below on my Ubuntu machine as well as Windows 10 and 11. (Chrome Browser, not Chromium is required)

You have to have the phone on the stated version of Android in the installer: PQ3B.190801.002

Link to this.

Your bootloader has to be unlocked.
Use the Android Flash Tool addon and Google Chrome to flash your device to the correct Android ROM - Choose the Flash link. It is the easiest way and clearest way if you have not done this before.

Do this when installing the ROM (just before):

Force flash all partitions - ticked
Disable verification - ticked
Disable verity - ticked

It is in the menu on the Android Flash tool. This will stop the device hanging at the Google logo.

Once You have installed Android and set it up, then go through the UT Installer procedure.

If you are OK on the command line and you wish to try with out Chrome have the device connected in fastboot mode to the PC and download the Link ROM rather than the Flash, extract it, open a terminal in the folder and run the flash-all.sh,
