Hello there, I'm using OnePlus 6t on OOS 10, somehow my kid changed the lockscreen pin and now forgot.
I've read multiple threads and asked a lot of people, but there seems no method to bypass the lockscreen pin.
I'd some important files which I couldn't backup/ not until my last backup.
Is there any way possible to recover my files after a hard reset as that's the only alternate i can think of without bypassing lockscreen without root.
FYI: Bootloader locked, currently locked, haven't hard reset yet, usb debugging off.

Nope, if you hard reset you lose everything. User storage is encrypted with a per-session key that is wiped when a reset occurs meaning everything on the phone becomes useless garbage the moment that key is lost. If you have adb enabled and have authorized your computer once before you might be able to pull files off using that but otherwise you might be screwed

The lock screen is designed to keep people out, wouldn't be much use if it let people exfiltrate data whenever they wanted

Don't even think you'll be able to get the pin off the phone. When you reset Google asks for the old pin used in the device.

If USB debugging is off, I don't even think you can flash stock firmware onto the device either.

You're pretty much screwed.

The best way to do is MSM tool. If you don't know the password your can't even get in to recovery mode( required password). By doing that all data will be gone.
