How To Flash Your Touch Pro

[CeltREI]

Hi all, first time flasher here.
I have Raphael_CDMA_HSPL_037 unlocking my Sprint CDMA Touch Pro and Downloaded Davideuck's V-4 ( http://forum.xda-developers.com/showthread.php?t=487602 )
When I enter the Raphael_CustomRUU v1.2 ( http://forum.xda-developers.com/showthread.php?t=410761 ) exe it gives me the signs that ye normally expect. However once I click on the Next button to start the flash ActiveSync will lose the connection, my device goes into the Bootloader, gives the progress bar and at 1% it errors out, restarts and I get this on the RUU:
"Error [244] : Invalid Model ID

This Update Utility cannot be used for your PDA Phone. Please check your Update Utility."

I've also tried installing it via memory card, it'll flash a quick message of "No Image Found" then sit in the Bootloader screen till I reset it.

How can I flash my Raph?
