Not sure how to load this onto the USB, do you need to extract the files first.
Z1 not booting at all.
There is included usb imaging software in the first folder I believe. You also need to unzip the .7z file, because it contains the image. Run the imaging software and choose the image that was unzipped.
I used a different usb drive thanwhat came with it and after a couple user error problems, I got it to work.
