I have a problem where I think that hasn't got a solution.

I have a Samsung A53 mobile device with a lockdown profile enabled.

This device was for pure testing but I've managed to Lockdown this device completley.  Device is not manageable anymore from within SOTI

* Device is in airplane mode.  I've added a Sim card, but airplane mode is active.....

* Authentication Password has been forgotten.

* Option to Factory reset the device is disabled after a hard reset. 

Is there some kind of master Administrator password?

I think I can only use the device as a doorstop now.

Any ideas would be great.
