There are three ways to reset Bitmain Antminer S19 series to factory settings:
1. Restore via “Reset” Button
When the miner boots, this technique can be used in less than 10 minutes.
After powering on the miner for 2 minutes, please press “Reset” button for 5 seconds, then release it. It won’t be necessary to turn off the miner because the factory settings will be restored in 4 minutes and the miner will restart automatically.
*Note: that the reset is only effective if the mining device has been running for 2 to 10 minutes; after that, it cannot be recovered.

*Note: S9 and T9 models must be online in order to update to the most recent firmware on the official website when using this method to restore the factory settings.
The miner with the SD card next to the Ethernet interface is not compatible with this technique.
The miner will have its original firmware after being reset. updated Antminer S19 firmware should be loaded into the miner.
This holds true for every ANTMINER.
