If this has been addressed before, I apologize, but I cannot find the answer, I have a couple of APX 7000s that were purchased from Motorola and are legit radios, I notice looking at the flash codes of each radio that CPS shows purchased flash code and used flash code, basically what is the difference and can any of the non-used flash items be turned on if needed by CPS?
Thanks for any help.
