My Bold stopped working...

Hello all.

I just created my account on Crackberry as I have a big problem with my BlackBerry...

Yesterday evening, I wanted to use it but the screen was all black like the device was off. I I tried to start it but nothing happened.
So I made a battery pull. All went good till I went to the "code pin screen" : I couldn't type it, I couldn't do anything, not even turning the screen off with the lock button...

I hope someone can help me.

Thanks in advance!
