I have a R4 Dongle for nintendo switch and my nintendo switch are already jailbreak, I wan't to use R4 Dongle but my R4 Dongle won't work.

When i connect R4 Dongle to my computer and when i click button on R4 Dongle nothing happen.
Yes I have done that but nothing happen.
Have you tried re-flashing the R4 UF2 file from their website?I'm using that one now but it don't help very much since i can't use R4 Dongle.
just download the UF2 file from Ra website, connect the dongle, and once detected copy the file you donwloaded.No how do I do that?
