The struggle is real. Update finally completed. I think I am pretty tech savvy, but had many technical difficulties along the way. After last reformatting of usb, redownload on another computer, re-extraction onto usb drive... install finally took. Make sure you format enough space for update. I think one time it for some reason took about 128megabytes for format. It let me install the file on usb drive but update erred out immediately on raptor install. I also tried downloading and transferring from a computer with encryption which was also an epic fail. Good luck with the update all!
