RioG Copy the files inside the folder to the root of USB. If you want to keep data, then delete the updatecfg.txt file
RioG Im also not sure what is meant by "latest version 1008 and not 0927
Well, for 7870, the latest version is 1008, and for 7862, the latest version is 0927. I guess the person tried to tell you this so that you don't have to be confused.
