I now flashed with
GD55_MAIN_112c_De_Fr_Es_It_Ru.01M.bin
GD55_Map_EMEA-UKP.03.02_UK_Vodafone.01F.bin

Enterd a GSM 900Mhz Chip & Signal came up , i tried to call and signal got lost & " Unregisterd Sim " came up , i removed battery put back on and signal is never found just " Unregisterd Sim " , i tried to reset settings but no luck .

I Insterted a GSM 1800Mhz Chip and all went ok . sounds like a hardware fault ! right ? its not accepting 900Mhz sim cards !

Hi,

It looks like no 900 Mhz coverage in your location or phone hardware fault. also check "band" selection in phone menu.
