I'm using the Android 11 delivery for the imx8q and am coming across the following scenario that is giving me a terrible time. This was tested with the stock Android build with no local changes. Any thoughts where to look to fix this?
Success path
1. Flash an A11 build
2. Do a factory reset <--success
Failure Path
1. Flash A11 build
2. Do an OTA update
3. Do a factory reset <-- failure
