1687 error on xpr6550
Posted: Sat Aug 13, 2022 4:27 pm
I have a 6550 that is in bootloader mode. When I hook it up to CPS 16.x and try Update, recover, read, anything, I get a 1687 error code which is cable compatibility. But the cable reads and writes my other XPR radios fine with this computer. I got the cAble in a trade, it is not genuine Motorola. Does a firmware upgrade use different pins than programming and it can be the cable? I am using windows 10. Any help appreciated.
