What’s the download address of Baofeng md-1702 to upgrade firmware v02.02.023
You have the link two messages above. But this is extracted firmware, not an official download site (you have to use old 1.0.66 CPS to flash it):
… I have flashed FW 2.2.23 extracted from my RT72 to DM-X to simulate your issues and it works without any problem with old 1.0.66 and new 1.0.78 CPS …
@waltercx3awb:
I am not sure if I understand you correctly, but could you try the Retevis 72 1.00.02 CPS or longer cable if you are using micro USB? The L firmware uses a different communication protocol which is incompatible with old CPS versions.
Con el CPS para el Reteis 72 ver. 1.00.02 se puede aceder al handy
en el post Baofeng DM-X DMR - #474 by waltercx3awb está el hilo con la solución
