Do you have a way to copy files to the sd card via your PC? If so, follow the sd card directions. When you do a hard reset, the phone will read the sd card, see the raphimg file and load it.
If you can flash with sd and you're stuck in bootloader, there is an app for the mogul that gets out.

I don't know if it will work for the TP. Maybe someone else here more knowlegable than me can help?
