After learning that voice calls don't work well with UT, I have to now reinstall Android on my Pixel 3a, and am having trouble. Here's my process and the expected results:

1. Downloaded the latest Android version for the P3a
2. Downloaded the ADB tool
3. Put phone in developer mode
4. In a terminal window, changed directories to the ADB folder and sent this command: ./adb devices. Device shows up as expected.
5. Send this command to change the bootloader: ./reboot bootloader
6. Change directories to the latest Android version and send this command: ./flash-all.sh
7. The Android OS should begin installing at this point.

Things get tricky at step #5. The phone powers down, so I know the command was sent. If I press and hold the power button for >15 seconds, it shows a Fastboot Mode screen with the options for Start, BarCode, Recovery Mode, and Restart Bootloader.

It seems no matter what I do, the phone still boots into Ubuntu Touch.

Has anyone successfully reloaded Android on a Pixel 3a from Ubuntu Touch?

Thanks in advance

@applee Ah, I understand, thank you. Could you possibly share a link with instructions on how to go back to Android on the Pixel 3a?

Hello, I installed UT on a Pixel 3a and am using an AT&T sim card. I am able to send/receive text messages but am unable to make phone calls. If I change the connection type to 2G/3G/4G, it shows that I'm connected to the AT&T network, but cannot place a call.

Are there APN settings that I could change?
