Looks like there is a precompiled windows version of Radio Tool However I downloaded it and wrapped the OpenMDUV380.bin file and attempted to upload using the official loader, and basically it didnt work. The official loader seemed to get it a loop where the progress bar kept going back to zero and...

RT3S is a rebadged UV380 Use MD-UV380 as the radio type I'm not sure why you are referring to CVS ??? This has nothing to do with the official firmware , which I think has someting like CVS or CSV in its name i'll try again with MD-UV380 i got the radio models while looking in the test/firmware fol...

From what I can recall the UV380/RT3S has at least 2, possibly 3 different types of display that can be fitte...

Which official version were you using to reinstall ? Did you say that you have installed the firmware using the same PC onto different RT3S radios ? and that it worked OK ? One other thing you could try is downloading and installing the OpenRTX firmware, which I think possibly can be loaded using t...
