we are sorry to hear that, it may be a time for the Control PCB unit to be replaced. Could be the control PCB itself or it could be the beagle bone or combination of both.

However, once in a very while... the MicroSD card physically goes bad. We have seen a few cases where simple MicroSD card replacement from a local store (kingstone or Sony 4GH) took care of the problem.

if another MicroSD card doesn't work, please proceed with the parts replacement via warranty. support @ bitmain . zendesk . com

Thank you

Please go to http://bitmain.zendesk.com and go to S4 Download Section. There are several version on bootable images you can use to restore S4 MicroSD card.

Using windows, is there software to flash the S4 image? I cant seem to find any software. I looked at windows disk imager but it only takes .img files

I tried this, it still did not work. I cant connect to it at all, but both LED are Green and the LCD screen is lit up just blank

Hello,

I have tried switching out the sd card as well as the beagle bone black. Neither has worked.
