<![CDATA[Hopefully Useful Tips]]>I spent some time yesterday trying to flash UT on my new Pixel 3a and got some info that might be helpful.

  • Issue:

    • OEM unlock is disabled (grey)
      • I was going through the first Android initial configuration skipping all (as I just wanted to check if it worked)
      • When trying to unlock bootloader from Settings menu it was not possible (message: Contact carrier or connect to internet)
      • Setting internet connection through wifi was not a solution
    • Possible solution
      • My device is not locked by any carrier
      • I had to reset Android OS
      • Insert a SIM when asked
      • Set language and region accordingly
    • After this I was able to unlock the bootloader

  • Issue:

    • Phone gets stuck on Google logo instead of booting into recovery
      • I had tried several cables and different usb ports without success
    • Possible solution
      • On the UBports installer, tick «Wipe user data»
      • Once the fastboot partitions are done, reboot into recovery mode

More known issues? Add them here

Thanks for the hint. In my case it was not enough, i got to install Android update (12) and do a factory reset then ( still having the SIM up ), then next run i was able to toggle on OEM unlock.

Note that by installing the required version later, the setting was greyed again but did not blocked the UT install process ( bootloader stays unlocked ).

I didn't have any problems with my 3a after I flashed Android 9 (Sargo).

I couldn't flash anything as the bootloader was locked. My device came with Android 10 (or something)

As @nero355 says, I had to check first with mobile data connection

It's very easy to do. During the Flash it gives you the option to unlock the bootloader. After I flashed it, UBPorts picked up my 3a right away and it installed pretty easily after that.

  • Some phones want to do the Bootloader Unlock stuff via the 2G/3G/4G/5G Data Connection.
  • Wiping Data is something you pretty much always do when flashing a Custom ROM or alternative OS on your phone!

So that explains the issues you were having 😉
