[Windows Central Question]

Tainted off my phone, when I turned it back on after entering my sim code I was asked to enter my unlock code as usual. Only this time nothing happens after I enter my pin and I can't log into my phone.
Tried rest the phone, take out the battery, with sim, without sim etc... no result.

Phone still seems to function as I get message notifications, it connects to the network but I just can't get past the lock screen.

Yes I'm 100% sure I got my pin right.
