So did you do these steps?
1. Unlock your Touch Pro using the HSPL Unlocker and according to your information it is a Sprint Touch Pro so use
This.
2. After you unlock you are going to want to reformat your SD Card to FAT32 so that you can flash from it so reformat it using windows (by connecting as a storage card and reformatting). You might want to backup your pictures and everything else on the card since it all will be erased.
3. Next take the RUU_signed.nbh from whatever ROM you choose (make sure it is for a CDMA touch pro and will work with your carrier) and rename it to RAPHIMG.nbh
4. Copy that file to the ROOT (just copy it straight to your sd card and do not put it into a folder) of your sd card.
5. Restart your touch pro while holding the volume down button and the power button (how you currently got to the tri-color screen).
This should be all you need.
