Help stuck in bootloading screen

[accurato]

yes i have tried to relock and unlock even tried Raphael_CDMA_HSPL_037 again with no luck. when i try the nbh from Hermann_C_SPRINT_WWE_1.03.651.3_RS1.03.15F_SPCS_1. 53_PRL6063_Ship.exe
by renaming it i get an error on the loading screen 00028002 not allow then it goes back to tri colour screen. when I try to load from the pc via usb it gets to 1% then shut's down and goes back to tri colour screen. Last time around i was getting corrupt file error's on the Raphael_CDMA_HSPL_037 instead of the usuall hang on loading screen. Although it seems sync. my computor does not recongnise the phone but the loaders seem to find the unit i am using vista 64 bit, and have installed all the drivers that are needed.
