3310 CONTACT SERVICE problem

I have got a huuge problem, a time ago i tried to flash my 3310 to 3315, something got wrong, and the process got canceled.
I flashed another 3310 flash file back to the phone, but now i only get: CONTACT SERVICE.
What shall i do? My phone were type: 4.47 or somthin.

....too.

After the flash take a datacable,set Imei,clear simlocks,set new faid and factory reset.
Then you take Knok Phönix and convert you 3310 in 3315.
That´s all.
