Can no longer read my previously readable CM200

[Flameout00]

What would cause me to not be able to read a previously readable radio?
I have 2 of the CM200 radios, that I was previously able to read and write, using Commercial Series CPS R05.12, on Windows XP.
Both radios are operating fine and both tx and rx, but when I went to reprogram them, one could not be read and just gives me error #768 (I do also have R05.16 and R05.18)
The programming cable is the same one used on the r1225 radios, and I can still read and write to them, along with the one CM200, so I'm pretty sure it's not the cable (purchased from bluemax49rs)

I hate to just junk the radio if it's salvageable, but I'm starting to wonder if it is

The programming cable is NOT the same between the CM200 and the 1225 series. 2 wires are flipped.

Motorola sold a dongle with a short RJ45 pigtail that allowed you to use the 1225 cable, but you needed to plug in the dongle onto the cable.

If you have a CM200 that allowed the 1225 cable to be used for programming, someone did some work internally to switch the mic jack wiring & flip the 2 pins. At least, that's my guess.

I was going by what the seller of the cables had told me. I had previously purchased the RKN4081 cable to program my r1225's and then after I picked up those two CM200 radios, I went to look for a programming cable, and saw that it also used that same RKN4081, so I asked the seller about it, and he told me they were identical.

It was reading/writing fine for the first few times I had programed the CM200's and still works fine on the one.
The last time I programed it (the one that I can no longer read), it was to attempt to use it as a repeater TX radio, and I programed the TX and RX with the same frequency. I don't see how that screwed it up, but something sure did
