D3 Control Board Program Recovery

This method applies to the following situations:

• The miner is powered-off in the upgrading process.
• The miner cannot start (cannot find IP).
• The miner can only use the default factory workers

Prepare before you go:

1. Computer with Windows XP system or above
2. Card reader
3. 16G or TF (Micro SD) memory card with less storage
4. Download the D3 firmware to the computer in advance from the link below: 

   https://service.bitmain.com/support/download

   Find your miner on the left sidebar and click to access the firmware file. 

5. Download the program that TF needs and unzip it: https://service.bitmain.com/support/download  Go to the left sidebar and click Flashing SD card with image >> Tools and Instructions to Image SD card. The files will appear. Select the file for your miner. 

Let us jump into the three steps.  

First, copy the program.

1. Install the TF card on the card reader, and then connect to the computer.
2. Format the TF card in FAT32.
3. Copy the extracted file to the SD card, and take out the TF card.

Second, please put the TF into the control board.

1. Power on the miner after installing the TF
2. Take out the TF after the miner gets its IP.

Third, upgrade the firmware

1. Please uncheck “keep setting” and reload the firmware.
