It will NOT, I repeat NOT WORK if it's called fwdc220b-x x.bin where x is a number e.g. fwdc220b-2 2.bin. The Mac sometimes auto renames the file in the download folder if the same file name exists from a previous firmware download. What I do is copy the latest file to a blank formatted SD card and rename it to fwdc220b.bin This works fine for me! Hope this helps?
This problem happens to a few users every tinme. If the old Update file remains in the Folder from the prior FW Update, using Windows we must choose whether to to overwrite or inrement-rename the file. Mac just automatically increments the file name and a few people get a fail to recognize message.
You should Unzip the file in a clean folder somewhere or rename the .bin file (I think that's harder) to get this to work correctly.
