Hi. I wanted to give GrapheneOS a try. I installed it via the web interface, it worked like a charm. Relocked bootloader, worked nicely. I saw what I wanted to see.
I decided I wanted to reinstall the stock image. I followed the web installer's details, I allowed OEM unlock, rebooted into fastboot, unlocked (fastboot flashing unlock), erased the Android Verified Boot key). All good.
Then I went to flash.android.com and it failed at the "lock bootloader" step. I tried to do things manually by downloading the zip and doing flash-all.sh. I had a warning: Warning: skip copying radio_a image avb footer (radio_a partition size: 0, radio_a image size: 97620108).. And fastboot flashing lock is now telling me this: FAILED (remote: 'invalid android images, skip locking').
I have reinstalled GrapheneOS just fine and re-locked with GrapheneOS installed. However I'd like to reinstall the stock image.
What can I do?
Thanks.
