I followed the directions, everything went well. I had noticed the iap4e.bin file in the stable folder, thought it wasn't included in the instructions because it was new, and stupidly decided to install it. Now I'm getting a 404.
Now I just want to start from scratch…can I get a link to upload the original factory files? I found one for the duetethernet, is there one for the wifi? There isn't a "sys" file in the duetethernet image folder, was there not one in the original duetwifi?
