- The miner cannot start (cannot find IP).
- The miner can only use the default factory workers.

Flashing Instructions :
- Insert MicroSD card into computer and format to FAT32.
- Unzip the downloaded image file and copy the contents to the MicroSD card.
- Remove the MicroSD card from the computer and insert it into the card slot on the control board.
- Power on the control board. Allow about 30 seconds for the files to load automatically. When loaded, the green indicator light will be steady on.
- Remove the MicroSD and restart the miner. In over 30 seconds, please reboot the miner. (NOTE: do not power off during the restart process; power failure will cause the OTP to fail to turn on which also damages the control board.)
- Power on the miner and access the miner interface. Remember to upgrade the latest official firmware online.
Possible solutions to solve the flashing failure
- Reformat the MicroSD and make sure you've copied the correct firmware.
- Press the MicroSD softly to ensure it's well attached.
- Dust and clean the MicroSD.
- Try with another good known MicroSD.
