Alrighty,
Do you have a microSD card? If so you'll need to get a hold of nueSPL 2.47. You can get that from here:
ftp://up.ppcgeeks.com/Titan/Users/No...ueSPL-2.47.rar
If you don't you'll have to do this all via USB. You'll need Olipro 2.40 for that which you can grab from here:
ftp://up.ppcgeeks.com/Titan/Users/Im...rd-SPL-MFG.exe
For the microSD card you need to unpack the nueSPL .exe in the .rar to your phone and run it from there. For the USB just plug in your phone and run the Olipro .exe from your desktop.
After doing either of those you'll be ready to flash a radio and ROM.
