Hi My phone can not get no service... I flashed it with froyo from america and since that my samsung i5500 can't get registered within my network providers (three.co.uk) is there any solution? I think i need to reset the service mode settings is that somehow possible? I already reflashed it with other various roms. no positive results. Is there anyway to wipe all data of the phone? like format of system disks and install the system like on fresh device? please help me
