I just went through this. How I got it to finally install correctly is the sd card method for board recovery that is posted in the thread. boot up from sd card. remove sdcard while it is on. Flash through web interface with the old L3 (not the + version) firmware that is on the bitmain website. (Antminer-L3-201704271449-384M.tar.gz)
Then flash the bliss firmware and it will work.

I sent 35 coins from my wallet to my exchange address. I am still showing unconfirmed 0 of 6 confirmations. I did this on nov 11. 3 days later . still nothing. Will it eventually confirm ar revert back to my wallet?
