Depot help for apx 4000hx

So my buddy just aquired APX Depot because he getting an APX thats flashed for analog only on 800/900 mhz and needs to flash it for p25 astro 9600 baud trunking capabilities before programming. His APX is an 4000XH. First of all he cant seem to find a digital apx4000 flashcode online anywhere to use to create the new codeplug. Second, hes tested creating a few for other apx radios he could find the flashcodes for and he keeps getting an error message that says flaahcode not supported my model H-Option is not updated. What does that mean? Please help. Thanks

Considering very few outside of Motorola facilities have gotten their hands on APX Depot…you’ll likely be out of luck trying to find help.
