I have an Antminer L3+ that has been working great the past couple months. The other day I noticed the fault indicator was blinking, so I turned it off, waited abour 10 seconds, then powered it back on. The fans spin, but the front lights never come on. My initial thoughts are the SD card probably needs to be reflashed. I looked on the support page for Bitmain has and while I found a firmware for the L3+, its not an image file and looks to be the one you use to do an upgrade from within the unit. Since mine is not operational, I cant use this one. I was able to find an image in one of the other sections, but they dont tell you which Bitmain unit its for.

Can anyone help me figure out how to get this fixed? Thanks!
