I had installed Ubuntu touch on my Pixel 3a, but during an OTA update the phone got soft bricked.
I am able to detect the phone through fastboot devices (using Ubuntu computer to access phone).
Tried installing sargo stock image 3 times, but without success. Still get the "no valid slot to boot" error.
Sharing the ./flash-all.sh run code below. Look forward to guidance. Thanks !

fastboot --set-active=b? (b because based on your log the stock firmware seem to be installed into slot b, you can also try to set it toa) – Robert Jan 21 '24 at 14:41
