The only thing i can think of is flashing by micro-SD. If you have the original stock Rom file, try opening it up with 7zip (similar to win-zip/win-rar). If you can locate the .NBH file, rename it to RAPHIMG.NBH and save it in the root directory of your Micro-SD card. When you reboot your phone, it should ask to flash the phone. If this does not work, the only thing I can think of is flashing the phone to a stripped down custom sprint Rom. This is all assuming you haven't already re-locked the SPL ( I don't know if flashing via Micro-SD with stock nbh is possible at that point). Good luck.
