This the Alltel 3.35.671.9 ROM with GPS enabled. Enabling GPS is the only difference this will make to your phone. This is OS-only so you will need to flash the OEM ROM first.

1. Flash the original
Alltel 3.35.671.9 ROM.
2. Connect to PC and copy TITAIMG.nbh from my ROM to a MicroSD and remove it from the phone. Or alternatively, use WinRAR to extract the original .exe file from step 1 and replace RUU_Signed.nbh with my TITAIMG.nbh file.
3. Install Hard-SPL 2.40 from Olipro

6. Reinsert MicroSD and hit RESET. TITAIMG.nbh will install. If it does not, hold POWER+CAMERA while pressing RESET, you will briefly see the tri-colored bootloader screen and it should load the ROM.
