EPROM ERROR IS EASY TO FIX READ THE RADIO USING CPS VERSION R06.12.02 OR LATER, CLICK OK ON MESSAGE ABOUT CORRUPTED FILE, NEXT WINDOWS SELECT RECOVERY RADIO.
RADIO WILL START OK, BUT NEED TO BE REPROGRAM TO YOUR DESIRE PROFILE.
HOPE THIS HELP EVRYONE WHO HAS THIS PROBLEM.

I've fixed a few of these without having to open the radio. Corrupted codeplug repair is an integral part of the later versions of Professional Series CPS. Have you tried to do this without removing the battery, and was it successful?

If you're using R06.12.xx it works fine without removing the clock battery. The rechargeable LiIon coin cell only powers the clock when the normal battery is removed.

Now, is your broken CAPS LOCK key as easy to fix?
