First put the radio of your choice on your sd card and name it TITAIMG.nbh. Make sure it's not within a folder or anything.
Then unlock your phone with hard-spl 2.40 (I will provide a link) You will need to have your phone connected via activesync to execute this procedure. Please make sure to follow the directions on the screen exactly.
Once you do that, insert your sd card the reset your phone into bootloader mode (power+camera+reset button) The bootloader will see the file on the card. Just follow it's directions.
Once that is done you can install the custom ROM of your choice aslong as it's compatible with your radio version.
