It seams that IMEI is croupted. Check with *06#.

zeez · 04-06-2007, 14:24

check the imei number if the imei is ??????????? then rebuild the imei using the ufs.
sometimes write the pm and then rebuilding the imei and unlocking also solve the problem

HI CHANGE THE FLASH IC THEN DO

@Talagang and @zeez don`t speak just to make noise. Now the solution depends of the problem, on DCT3 Contact Service could be caused in 90% cases by "COBBA" and software. I reccomand full erase of flash and writing of a new software of course last version, with eeprom. In case is Cobba damaged this must be exchanged with a functional one and phone must be reflashed and soft repair must be done also(faid, imei repair). Contact Service is most frequent deffect found on 2100-NAM2, and 95% of cases is caused by wrong informations on EEPROM, repair is reflash of the phone and restore original IMEI.
If u have any questions u can contact me on yahoo messenger on "china_alex_2000" id.

contact service:
1)EEP or flash checksum problems:flash phone ,write virgin eep ,rebuild IMEI
2)Cobba: change cobba then unlock phone.
3)COBBA capacitors:check capacitors near cobba for shorted one.this is very common
4)There is no V_COBBA:check Vcobba transistor near cobba for 2.8V .It is common problem too
5)IC flash proble,very rare problem
