Before installing BraiinOS+, it may be necessary to reset your S9 to its factory settings.
This method can be applied between 2 minutes and 10 minutes after the miner starts.
2 minutes after turning on the miner, please press the "Reset" button for 5 seconds, then release it. The miner will be restored to factory settings within 4 minutes and will restart automatically (there is no need to turn it off).
