I've managed to install the update by taking out the sd card from the antminer s4 and replacing the 'initramfs.bin.SD' with the new firmware's version of 'initramfs.bin.SD'.
It still has the same issue of not mining what it says its mining.. :l
I wonder if that updates everything that needs to be updated. Might try later if I go back out to my garage.
Edit: Your load average is much lower than mine, I'm guessing it hadn't started hashing since it's showing an uptime of 0 minutes.
