I think the Open GD 77 cps is not set up correctly or is not a Valid one to use. Does anyone have one that does work and have everything needed to upgrade my dmr 1701?
I am having problems Upgrading my DMR 1701 to Open GD 77. It will not find a COM PORT for uploading. Please advise if anyone has ever had this issue and how to remedy it. If anyone has a good download for it. Thank you.
