  • The miner cannot be started (Unable to find IP of the miner).

  • Miners can only use the default factory workers.

  • The recommended capacity of the MicroSD card is less than 16GB. It is not recommended to use larger capacity MicroSD cards because they are prone to errors.

  • Computer running Windows XP or higher.

  • Card reader

  • USB memory disk: 16G and below, the probability of other large capacity problems is relatively high (only for A113D control board)

5. Remove the MicroSD and restart the miner. Please restart the miner if it exceeds 30 seconds. (Note: Do not power off during the restart process. Power off will cause the OTP to fail to boot, and it will also damage the control board.)

6. Turn on the miner and enter the miner interface. Remember to upgrade the latest official firmware online.

1. Reformat the MicroSD and make sure you copied the correct firmware.

2. Press the MicroSD lightly to make sure it is well connected.
