Oh yea... and one more thing... When I go to flash the S4 Firmware I get this:
"tar: invalid magic tar: short read cp: can't stat '*': No such file or directory"
What is the deal?

Might be a reading thing

This link has only been posted about a dozen times in the past day in this thread.
https://dl.dropboxusercontent.com/u/24462711/initramfs.bin.SD-20141003-1.tar.gz5 of 33 units not functioning is no laughing matter, but if you missed that link easily enough then maybe you should RTFM and see if you are doing something wrong

Contact the user BitmainWarranty via PM, and try calling their support line too.
They will help you.
Can't help but imagine you must be doing something terribly wrong to get those results. Still not sure how you missed nearly 3 pages of instruction in this thread regarding the firmware upgrade.
