Hello W4ADC;
Did you solve your problem? If not, i might help you. You did not mention your firmware version. Anyway there is a tool named flashburn for hytera radios. Unfortunately sharing such tools on this forum is forbidden i think. But you can find it online
1. Download and install flashburn
2. Read "user_defined" data. The result should be approximately 15-16Mb(You need programming cable for this)
3. Send that file to me. I am going to brute force and try to find your pass or reset it.
