Hi, you tell me how I can do, do you have a guide? Thanks
Bitmain does not respond to my ticket, but I can not understand, the products before being sent are not tested.
Where are you located? For US residents, you just need to open a repair ticket and send the defective unit to CA repair center under warranty. Bitmain shipped a new D3 from china within 2 days of delivery of my defective unit to CA repair center.
