Do not power off or perform any operations on the miner during the firmware reload or upgrade process. The whole process takes about 5 minutes. If it exceeds 10 minutes, stop and update again.

3. Set up your miner normally, get the IP and log in to the miner user interface.

4. Upgrade the second firmware update_1000.tar.gz

If the upgrade is successful, it will display "System Upgrade Successfully".

Similarly, during the firmware reloading or upgrading process, please do not turn off the power or perform any operations on the miner. The whole process takes about 5 minutes. If it exceeds 10 minutes, stop and update again.

Otherwise, the upgrade will fail and the miner will be damaged.

If it keeps failing or the ASIC status starts to show "??", it means that the miner is not working. Troubleshoot and repair the Hash board or replace the Hash board.
