I have googled and tried looking up that error code and have not found anything helpful. All I found was what you already had which was the rsdlite program and the sbf files.
Im assuming you are following these steps:
Method 2: While phone is off
To manually put your device in bootloader mode:
Turn off device
press and hold the up and down volume buttons
power on device (continue to hold the up and down volume buttons)
wala - you are in bootloader mode
Launch RSDLite (make sure device appears in window)
I will continue to look for a solution.
