Revert Android 11 to Android 10...

[edved]

I have been on Android 11 DP since it was released and for the most part it has been stable. Unfortunately, my password app isn't working and could take months for it to be functional on 11.

Has anyone had success reverting back to 10 from 11? I've tried more times than I care to admit, but have not had any success.

Any suggestions would be welcomed.

I've tried several times, but have been unable to revert back!

Take note of which partition you are on, either A or B, check this on the main bootloader screen at the bottom of the screen. After you see if you're on A or B, flash the March factory image. As soon as the flash completes, you need to go right back to the bootloader screen and switch to the opposite partition that you are on. For example if you were on A before flashing the image, you need to switch to B and visa versa. To switch, from the bootloader screen type: fastboot --set-active=a or fastboot --set-active=b

After switching the active partition, reboot the phone and you'll be able to boot into Android 10 and will no longer be stuck on the 11 preview.

I was having the same problem and this solved it! I had to download the tool from the Google site and copy/paste it into the "flash-all" folder and it worked!
