I've tried updating the firmware on the S4 and I get a SD directory omitting error.
S4 is not hashing correctly with elgius, so I moved back to ghash.io and set worker difficulty to 2048.
Hashrate at the pool fluctuates between 1.85 and 2.05 Th/s in the last 24 hours. Noticing ghash keeps redirecting me to uk1 and uk2...will test with us servers.
Use the link previously posted several times in this thread for the latest firmware without the "SD omitting error"
this one:
https://dl.dropboxusercontent.com/u/24462711/initramfs.bin.SD-20141003-1.tar.gzIt will update cgminer from 3.12.0 to cgminer 4.6.1
It does NOT fix the difficulty issue.
Setting your difficulty manually at the pool you are using to 2048 is still recommended strongly.
