I tried doing this and I followed your steps to the T without a problem, but when I put it on my M3iZERO card, and load it, I get the message Code: No system file found ! Put system file in It's white writing on a black background. If you are able to let me know what I did, that would be EPIC! Or are you able to post a direct link to a completed firmware as a ZIP on here? Thank you!
