2. Unzip the downloaded image file and copy the content to the MicroSD card.

3. Remove the MicroSD card from the computer and insert it into the card slot on the control board.

4. Power on the S19 control board. Allow the file to load automatically for approximately 30 seconds. After loading, the green indicator light will be steady.

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.)
