 For normal usage, the stabilizer must be configured with USB console later (try ``help`` command first), to set its IP address and MQTT broker address. However, for general testing (like the one below), you don't need to configure it any further.
 
+### Clearing settings
+
+In case someone sets some setting wrongly, or updates the firmware and suddenly there's an incompatibility, you may find (firmware, not yourself) in a state of panic, where it will not allow you to change the settings back.
+
+1. Get into DFU mode (described above), probably with jumper method.
+2. Use dfu-util to clear the flash completely:
+
+```
+dfu-util -a 0 -s 0x08000000:mass-erase:force:leave
+```
+
+3. Reflash the target firmware.

 1. Ensure that the [firmware](#getting-the-firmware) has been flashed onto the Stabilizer
