# Factory Reset

In the extreme case that the Bash Bunny has become permanently inaccessible or inoperative, there is a quick method for recovery using a special boot pattern.

1. Set the switch to arming mode (closest to the USB port)
2. Plug the Bash Bunny into a USB port and unplug it immediately after the green LED turns off
3. Repeat step #2 three times
4. Plug the Bash Bunny into a USB port and wait approximately 5 minutes for it to reset. The LED will either show an alternating red/blue "police" pattern or blink red.
5. When the firmware recovery has completed, the Bash Bunny will reboot, indicated by the green LED, then go into arming mode, indicated by the blue LED.

This process will restore the Bash Bunny to the original factory firmware version 1.0.  At this point you are advised to update your Bash Bunny to the latest version.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://documentation.hak5.org/bash-bunny/troubleshooting/factory-reset.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
