How to Update DMR-1701 to Open GD77 on Windows 10 pro

[WSCN925]

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.

I have used OpenGD77 and OpenUV380 many times without any problem finding the right com port.  Have you loaded the correct driver for the cable? When you plug in the cable, watch in Device Manager to see which com port is created.

Typically it is a driver problem.  Have you programmed any other radios with this computer/Windows 10?

Do you have the "official" USB to K-1 cable that is designed for this radio?  Similar to Baofengs DMR RD-5R and DM-5R radios, the USB chip is inside the radio and hence the cable does not have a USB chip, so that Baofeng cables for the UV-5R and other analog radios will not work here.  I purchased a few extra cable from AliExpress for less than $3 apiece and they work fine!

I did have problems attempting to install OpenGD77 on a DM-1701 in Windows 11, so I went back to Windows 10 and it installed flawlessly.

BTW: I personally hate the "flaw" in these Technical Discussions posts that rank them by "popularity!"  In the future, I would suggest these types of questions be posted on the Ham Radio subtopic here on myGMRS.

i have some issues with connecting my new DM32 and finding com ports with Winoows 11.. Sometimes it works sometimes nada and thats going through the process of confirming the Com Port as Steve suggested.  The radios start to connect than fail before really getting startedd.   I'm not having any issues at all on my Windows 10 Labtop..  Even tried unning the software in compatability mode on Windows 11 w/ no luck. For whatever reason, it will evently connect on 11 but takes several attempts sometimes
