No Radio! please help already searched.

[son303]

I got a 6800 that i tried to flash with a alltel rom, i used the titan unlocker which unlocked it fine, than i flashed the alltel rom into it and now its lost its radio. i tried seraching and doing everything ic ould find but nothing works.

the boot loader is 2.14 M09 B03
TITA100
SPL-1.20.0lipro

I tried to put int he nbh file via microsd card also. I was reading a couple threads about how the bootloader and the rom verisons do not match. What can i do to get the radio back on?
any help would be great.
thanks
