i used use mt-box to earsed my nokia 6620's MCU and EPPOM area. after that i flash it back with 3.14 firmware and PM but it Always Drops Calls ( Receptions are much Worse than before but signal bar are always full) and Can't Use GPRS now also the voicemail icon won't pop up even i have voicemail. Any idea?

I think i need to do a Full flash ( as flash a empty phone) but how to do that?
