This problem has been discussed at lot of times for the 5110. It works the same way with 5130.
In short you'll need at least the following things to repair your phone:
- MBUS or M2BUS cable to connect your phone to a COM port.
- EEPROM Tools 3.1 and/or 4.0 to test why your phone is in Contact Service; maybe they can repair it, too.
- Maybe Rolis Flasher 4.78 to flash your phone.
- Maybe some flash files (http://www.gsmflashes.com).
