Thank you very much.

3 was loaded after i extracted the files to the card. I tried the zip method to install 3.4.1, but it said there was missing bin files. So i just updated the 3.4.1 bin file manually

@phaedrux m115 shows rrf 3.0.
I'm away from the printer once I get home ill try ur suggestion

So i have designed and built 12 different cnc machines and this is the first time using RRF. I am using a duet 2 board i was able to connect to the board with dwc and I tried uploading fw to 3.3. I then did some research and realized I had to update to 3 first. I did this and tried to go back to 3. When I try to connect via dwc I still get the incompatible fw error. If I hit reset i get a json error.
Edit.
So I seen this thread and I connect to the board with yat and i get rrf 3.0 with m115. Ive put a fresh copy of the sd card zip on the card after I thought I could just throw the bin file in the /sys foler.
