still getting error 244 model id

[jwinn35]

i have unlocked, relocked, and unlocked my phone and when i go to flash to mighty rom i am still getting error 244 unknown model id. ive tried to flash both pc and sd style. when i try sd style it flashes something real quick that looks like image not found it flashes so quick i cant really tell. i renamed it RAPHIMG.nbh and put it in the root part of my sd card. can someone help please. here are a few more things when i look at my bootloader screen it always says security unlocked even when i try to relock it and it has spl 0.37.0000. thats when i relock. when i unlock it says security unlocked but it has spl 0.37. cd... whatever it says. also everytime i go into the program it says current rom 1.03 and updating to whatever rom i try to use. mighty rom in this case. even when on my bootloader screen it says spl-0.37.
