I have a question for those of you who have done the TF card firmware update. I have build dates of ~11/13/17 on all 10 of my a5s and they do have the TF card readers installed. When reading the manual for flashing via TF card it clearly shows how to set the boot image on the card. But then the last part of the instructions tell you to go into the miner via browser and update firmware there. It says to do it from the firmware you dl onto your pc and says nothing about using the tf card.

What exactly do i do with the tf card i just setup? Put it in there and update firmware via pc using web interface or does it update off the tf card? I'd rather not brick these things, i've already got 1 with a dead hashing board and many others with the pw problem...
