I have a Blackberry 7520. Hopefully someone on this site can help me. Being so fast paced, I did not back up any of my business contacts. Today an error message appeared on the screen while I was in calendar mode. I've only had the phone for 4 months but have tons of business contacts that I desperately need.

The message reads:

Device in cal mode.
S/N mismatch. RBSNx.
V: Vibrate, L: Led, B: Buzzer.
_________

I've tried to press all keys and can't get it out of this mode. I called tech support, of course they could not help. There has to be some way to get out of this mode. I don't know if its the "cal" means calendar or calibration. I think its callibration. When jogging the trackwheel it goes through a series of collors then back to the error message. When pressing any other key it states on the bottome of the error message key "f" is pressed, or whatever key is pressed.

Can any one help!!!!

If so email me at the listed email.
