Don't flash with the potentially bad image, use the one in post #2. Then post a screenshot of the interface if its still up while frozen.
which screen to you want me to screenshot? Most times I can't connect to the miner via the network when it stops hashing, but I will give it a shot. I am burning the image from Post 2 now and giving that a shot.
I have it setup for 2 pools - BTC and GHASH
I have never seen any "X" under ASIC status. I have seen X's on my S2 when I overclock it too far, but I haven't messed with any settings other than network and miner config on the S4's
