# Restore factory defaults
WLAN Pi Go features built-in eMMC storage. In principle the software image flashing process is similar to SD card but there is no SD card.
{% hint style="danger" %}
Read before proceeding. This process completely erases all data and all system settings. Please backup any data or extra apps you might have stored or manually installed on the Go unit.
{% endhint %}
1. Disconnect the USB-C cable from the WLAN Pi Go.\
\
2. Place the Go on a desk with its back side facing up. Note the little hole providing access to the Reset button.\
\
3. Use a paper clip to **press and hold** the Reset button. USB-C cable is still disconnected.\
\
4. While still holding the Reset button pressed down, connect the USB-C cable to the WLAN Pi Go and your laptop.\
\
5. Wait for 5 seconds and then release the Reset button.\
\
6. Accept the security prompt and allow WLAN Pi Go storage to connect to your laptop.
7. Download [Balena Etcher](https://etcher.balena.io/) app to your laptop.\
\ **Important note:** The latest Etcher version 2.1.7 has a bug, which prevents Etcher from opening the WLAN Pi image. Use version 2.1.6 as a workaround for now.
8. Download the latest WLAN Pi Go software image from [www.wlanpi.com](https://www.wlanpi.com/downloads) to your laptop.
9. Start Balena Etcher app. Select the software image. Select the Compute Module device which represents the WLAN Pi Go built-in storage.\
\
\
10. Press the Flash button and wait for about 10 minutes. Please make sure your laptop doesn't lock its screen. If it does, the flashing process might stop and you might need to restart it.
11. Once the image has been successfully flashed, disconnect the WLAN Pi Go cable from your laptop. It is now ready for use. Connect it to your phone, iPad or laptop and download the WLAN Pi Go mobile app.\

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://userguide.wlanpi.com/hardware/wlan-pi-go/restore-factory-defaults.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
