I'm trying to find a method to cram a new flashcode into my XTL5000 (have someone I can turn to, to get it done but rather learn how to do it myself as usual) to install some new features (ADP which by what I gather from what I've seen is simple software encryption and some more).

I've done some goggling and come up dry. I thought (hoped) that perhaps the Depot tool may have had a nice lazy method but no luck it seems (still looking at that before I play too much.

Does anyone know of any documents on the web explaining the process to enhance our radios in such a manner?

Thanks.
