1st - Plug the phone into your PC, make an activesync connecting. If activesync is not possible goto bootloader screen (Press POWER + CAMERA + RESET) and then RUN Titan_Relocker.exe and follow the onscreen directions. 2nd - Now you have the stock bootloader on the phone. You should be stuck in the bootloader now even after you pressed reset. Now open the RUU.rar file with winrar and extract the folder onto your desktop. Move the Ruu_signed.nbh to the RUU folder that you just created on your desktop. Open the RUU folder and RUN the ROMUpdateUtility.exe and follow the onscreen instructions. This will downgrade the ROM and RADIO for you. BE PATIENT, LET IT RUN COMPLETELY. When it reboots, you are back to stock ROM and RADIO.
