I have installed AMS and AT on my Sony Xperia Mini Pro few months back. I do not recall the PIN for it.
Also I do not have recovery phone number set.
I am using the same sim card since the installation.
Couple of days back I restarted my phone after a battery drained out.
AMS locks the phone saying “the phone is lost or stolen.” with buzzer. and email to report the device.
I have tried to unlock it through PIN with no luck
Unfortunately I do not remember my PIN.
Every time I enter PIN and press Unlock it just clears the entry box and continues the audio message “This phone is lost or Stolen”
