ok guy, if you just want the stock alltel rom, do nothing but download the newest alltel rom and upgrade (that should work if ur stock)

If you wanna put custom roms like no2chem, or DCD, then install oilpro 2.4 then download newest sprint rom (
ftp://up.ppcgeeks.com/Titan/RUU/RUU_...CS_AM_Ship.exe) install that to update radio and OS. Then download new custom rom and install that.
That should work...
