Hi there,

I got this problem: the blue LCD don't show anything and the red light is on and the Beaglebone don't show the blue light, only a red light, like the LCD. And no answer from Bitmain.

But serching, I find the troubleshoot for this, here in bitcointalk.

We need a MicroSD 4Gb Class 10 recommended, maybe could be used one of 2Gb, I get a 4Gb Class 4
I use Windows 7 x64 Ultimate and MicroSD to SD Adapter

Before proceeding, power off your AntMiner S2 after a few minutes, and then power on and wait for a minute, to see if the same behavior continues. If doesn't works, you could continue.

Here the steps for Windows:

- Download this files: Win32Imager and SDFormatter https://www.mediafire.com/?ud7js96s4j1jl5c and AntMiner S2 Image http://www.mediafire.com/download/p64ggw7sxypl649/bitmain.img.zip

- Install SDFormatter and open. Select the correct drive letter for the MicroSD, open options and select Format Size Adjustment ON and now, press Format, the MicroSD must be on FAT32.

- Extract Win32Imager and the bitmain.img. Open Win32 Disk Imager and select the MicroSD letter on Device, click the left folder icon and select the bitmain.img. Now, press Write.

Once the image was written, extract the MicroSD with security, open your AntMiner S2, remove one or two blades for easy installation and change the MicroSD, put in back the modules, and now power on PSU and wait for about 40 seconds, the red light will stay be for a while and then, going to works. Now setup your AntMiner S2 Grin
