I have spoken to TYT and they have given me the software to bypass the password and get the radio working again! The instructions are as follows:
1: Download the software (https://www.dropbox.com/sh/rdt7j67ou…wUUY6h14a?dl=0)
2: UnRar the file
3: Run DMR.exe
4: It looks like the normal CPS but it doesn’t like pre-existing codeplugs. Connect your radio and download the data (you will not be prompted for a password).
5: Alter the code plug you have downloaded and fix the programming password
6: Re-Image the radio using the updated code plug (you will not be prompted for a password).
7: Close DMR.exe
8: Re-Image the radio using the correct Code plug from CPS v1.36 or your normal version.
