You can't repair IMEI with Unknown BB, you have to repair BB first then you can repair IMEI, there is something you should know first, Unknown BB could be HW problem, but there is a SW work to do first, try to flash the latest modem firmware for your phone via Odin in CP section (Flash the file twice without Auto-reboot checked),
I9505_5.0.1_MODEM.tar
If BB is still Unknown, Now it's HW problem, BB need to REHOT or REPLACED.
