I didn't have any luck with SD card solutions out there. Here's a post I wrote about swapping the stock S2 Beablebone Blakc with an Off the Shelf Beaglebone Black.

#1) One them only give me a blue LCD screen. No data and no network connection. I have red lights on the back plane and green/red lights on the control board.
I'm experiencing problem #1. Did you get yours working? If so how?
Thanks.
Thanks. I will try this in the AM. I really hope it works...

Hi I believe I have the solution to your issues. I spent more than 6 hours troubleshooting this.
My Antminer S2 had the same issue and I believe it's the SD card inside the Beagleboard that they're using which is a 4 gb Kingston (I'm not sure if it's genuine).
Even reflashing the sd cards with a new image and it will still not hold the settings.
I tried with a new SD card 2 gb that I had lying about and flashed it with an image I found somewhere on the forum here (i can't remember where now). Note this is not a normal flash via the GUI but it's a full sd card flash.
Step 1: Removing the beagle board and the SD card:
Remove the control board (the one in the middle) and you should see a micro sd card slot. Press on it and it will pop up.
Step 2: Changing to a new SD card
Download the official image they recommended for a 4 gb (link provided by BitMainTech) via a support e-mail

Put it into a sd card reader and use the below app to flash the img to the NEW sd card.

Replace it the sd card and remount it inside. Give it a go!

I hope somebody can help me out here.... I purchased 3 of the antminer S2 Kits and installed them yesterday. (worked on them till about 4am) I have a few issues with them...
#1) One them only give me a blue LCD screen. No data and no network connection. I have red lights on the back plane and green/red lights on the control board.
#2) The other 2 units do not save any setting on reboot. So if I change their IP or pool configurations I loose them when I reboot. ...
Help!
