I recently purchased a Motorola XTS 2500 from an ebay seller with tags. Radio Came WIth FPP, Flash COde is 520001-001304-7, Firmware is 9.00.28 and DSP is 15.00.05. I took the radio to a friend who is attempting to re-program it to change abc toggle switch, remove zones and is unable to modify it. He cant even modify channels, he is Using Astro 25 cps v.16. Has anyone come across this issue, any solutions?. Any Help Is Highly Appreciated
