I have forgotten the PIN of a device but I do have access to a root shell with adb shell and su
Is there some way I could remove the screen PIN lock or change it?
Reset PIN from adb shell
Question
Answer
if your device is not encrypted with login credentials you can delete locksettings.db
adb shell su -c "rm /data/system/locksettings.db*"
However, bear in mind the following files are required for FBE encryption. If you delete these files you won't be able to decrypt userdata partition, all data is lost
/data/system/gatekeeper.password.key
/data/system/gatekeeper.pattern.key
/data/system/locksettings.db
/data/system/locksettings.db-shm
/data/system/locksettings.db-wal
