Are you sure that it is C6506 phone model? Please check that on the sticker under back cover... If you will flash wrong firmware for example C6506 firmware to C6502 phone you will get no imei / no baseband result... And flash correct firmware.

Great... Now download C6506 firmware and flash your phone. If after that you will see no imei / no baseband problem - it must be hardware then. Check modem ic... however there is no electrical schematics available so you must inspect main board and find it by yourself.
