A while ago I installed GrapheneOS on my Pixel 4a but left the bootloader unlocked. I was using it for a while but having the bootloader unlocked kept bugging me so today I finally decided to lock. I just quickly checked the documentation for the command but unfortunately didn't read the line about the command fastbook flashing lock doing a complete wipe of the system. Now the data of my phone is gone without a recent backup.

Is there any way of restoring at least some user data from before the flash?

    d5n Is there any way of restoring at least some user data from before the flash?

    Absolutely not.

      Nuttso what about with photorec? Is the entire device encrypted like with LUKS? Now that I mention that, is there no way to do LUKS encryption in GOS? Where you would need to enter a password to unencrypt the drive?
