Hello, first I`m sorry that I`m not speak very well in english ;)

So problem is that I bought from ebay this phone model. Detail is with XS++:

16:04:20| Profiling SEMC phone...

16:04:20| Platform: DB2020

16:04:20| OTP CID: 49

16:04:20| EROM CID: 49

16:04:20| EROM Color: Red

16:04:20| IMEI: 35342701xxxxxx

16:04:20| Phone ID: K800

16:04:20| Region: ORANGE_GEN

16:04:20| CDA: CDA102511/47 R17A

16:04:20| Firmware Version: R1CB001

It is locked by United Kingdom Orange network. I would like to unlock it but I can`t find any useful firmware for this phone. Maybe someone has same type R1CB001 firmware file .MBN and .FBN files? Would be very thankful of yours help.
