You need LAB, run in pure DOS...NOT a window. You will need an unpacked S-record IIRC.
Your flash is a basic as it gets, so pretty much anything you force into the radio will upgrade your features.(the one you have shown will add P25 digital)
be sure you have the right firmware in the radio to handle the flash.
and you will smoke the tuning values in the radio, so write them down beforehand.
If your going to attempt it, its worth some quality time searching and reading on the batboard, all the info is there.
