7600 flashing eeprom problem

Hello,

I had 5 x Nokia 7600 to flash, but After flash by my Prodigy box, they basicly haven't signal,
after some while I have realized that it's switched in the UMTS mode after flash.
But I have tried to write various PM file to theese phones before I realized it,
I also wrote there something what should be a full 7600 eeprom, but it made me a problem,
the phones are restricted, and prodigy can't access it's lock area - can't read or write MNC an MCC locks, and there is no way with my PM files and flash files how to change it.

I know that Griffin can repair this thing, but is there some way how to do it on the Prodigy box. Is there someone who have full clear PM for 7600???

Thank you
Shef
