Day 3 for me and I still have a S3 that can not hash as it doesn't display any hashing boards.  I flashed the ROM with:

antMiner_S320140811.bin
antMiner_S320140826.bin
antMiner_S320141013.bin
antMiner_S320141024.bin
antMiner_S320141126.bin

I've also tried the reset option from the GUI (button doesn't work),
