Hi all, my raspberry pi SD card corrupted, and I didn't have a backup of the firmware used for the miner.
I've tried 2 versions of firmware for Dragon miner although they boot but don't connect to the network. How ever I tried a normal PI OS and it did connect so its not a problem with the Raspberry PI.

Its the same miner as this one: http://szsunrisebtc.en.alibaba.com/product/1894616818-222009804/1_5_THS_1ths_Bitcoin_Miner_Mining_machine_Fast_Shipping_6_Modules.html
