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.

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 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.

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

OK.. I found the problem last night.  I run a PLEX server though my QNAP connected to my Windows 11 Box.   When i stop Plex services but leave QNAP running i don't have any issues with my com ports and can connnect 100% to my DM32's.. So i know its PLEX and not QBAP.   PLEX is somehow screwing with my COM Ports when QNAP is streaming. I have a ticket in with PLEX to see if they can hlep me with this..  I found this by shutting down services one by one..  This was driving me nuts because connecting was spontanious,  it worked most of the time but now i now what is causing it.  I never ran PLEX or QNAP on my 10 machine so it was alwasy unmolested.    So i have a suggeston to the OP having similiar issues.  start shuting down servicesa as you try to connect and see if you can find a siilair issue    Good luck
