I've tried flashing multiple firmwares and each time, I get a screen that asks me to enter the lock code to access the phone. I bought it second hand, and the lock code is long lost.

I heard something about flashing v1.2, then trying to brute force the PIN from there. I haven't been able to find a copy of the 1.2 firmware that doesn't ask for a pin code. Some guidance would be amazing.
