For some reason, my Antminer S4 card became corrupt. I went out and bought a new SD Card, but I am unsure of how to put the firmware on the card. Any help would be awesome thank you!
You will need a copy of the S4 image. If you use a program like win32diskimager you can burn it to the new SD.
There should be a few images in S4 thread that are backup. You need backup not firmware image.
