# Upgrading MUGIC Firmware

1. Visit[ http://mugicmotion.com/](http://mugicmotion.com/) and follow the upgrade link.
2. Download the latest published firmware (e.g., a file called main.bin).
3. Connect to MUGIC® in AP mode.
4. Visit[ http:/192.168.4.1/upgrade](http://192.168.4.1/upgrade) in your browser.
5. On that page, click on "Choose File", choose 'main.bin' from your Downloads folder.
6. Click on "Upload". A progress banner will eventually indicate "Progress 100%".

Wait up to a minute for validation until the page says "Firmware upgraded. Device restarting". The device will restart with the new firmware installed. You can reconnect to it, if needed, and verify the new version by visiting[ http:/192.168.4.1/](http://192.168.4.1/)

{% hint style="info" %}
Troubleshooting: If validation fails or the connection is unstable upload may fail. The page will say "Firmware upgrade failed" or a popup will declare "Connection to the server was lost." In that case a power cycle (turning MUGIC® off and on) is recommended and restarting the process at Step 3 above.

## 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://mugic-motion.gitbook.io/mugic-r-documentation/upgrading-mugic-firmware.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.
