I need you help!
After I updated the software to dig other coins, mine machine crashed can not log in!
hmmz sounds like you didn't flash my firmware. (as you can only mine x11 with mine...)
For rescue mode:
flash this image on a micro sd card (I used win32diskimager) and put that in your d3 controller board
