You might want to try updating to the S3+ firmware
S1 upgrade kit uses S1 control card that has the frequency set to 350Mhz.
These upgrade kits need lower frequency to hash.
You can download the firmware from bitmain website at
https://bitmaintech.com/files/download/antMiner_S320140826.binthen, log into your web control panel, go to, SYSTEM tab, and Upgrade tab
Please UNCHECK "keep previous setting" and apply fresh upgrade
Hope this will help!!
One of my antminer s1 upgrade kits isn't working. I think it has something to do with the fact that it is showing 4 chains in the miner status. Please help:

From what I have been reading, the most common thing is to make sure you update to the latest firmware. Or it wont work at all.
Yes I updated to the latest firmware. I have 2 upgrade kits, the first one worked fine. This one isn't working at all. I suspect it has something to do with the 4 chains it is showing. It's only supposed to show 2 chains. Or atleast my one that works only shows 2 chains:

I had the same problem, Just reseated all the cables and it started working. Hope this helps!
