# Flashing OS for iSG Box

**ATTENTION:** Flashing the OS will erase all data. Please back up your data before proceeding.

#### **Preparation**

1. Prepare a USB A-to-A cable (e.g., [**THIS**](https://www.amazon.com/dp/B07KJFWYXF)).
2. Get a small screwdriver or similar slim stick (diameter <2.9mm) or just a paperclip (for resetting the iSG Box).
3. Download and install the hardware driver [**Rockchip Driver Assistant**](https://drive.google.com/uc?export=download\&id=1j2phQA_7_FIGTW5EsZL_plLrBKMhxhZ1) (Windows only).
4. Download the utility software [**FactoryTool**](https://drive.google.com/uc?export=download\&id=15ovSGWlMg0A-QBHtjX-D67CdkIIzXPke) to your computer (Windows only).
5. Download the latest **OS File** for the iSG Box from one of the following links:\
   [**iSG Box SE**](https://drive.google.com/uc?export=download\&id=19GfJVbo4DmtYc-JYTWrySAFLHDqrCDaO) (MD5: 290E585B8373BFCAFBAB2EC24B312377)\
   iSG Box (not available now)\
   It is highly recommended to check the MD5 value before flashing ([**Download MD5 Checker**](http://getmd5checker.com/)).

4. Insert the screwdriver or paperclip into the hole labeled **"AV"** and press the reset button (located at the bottom of the hole—you’ll feel a click).
5. While holding the reset button, connect the iSG Box to your PC using the USB A-to-A cable.

> **Note:** Use the **USB2** on the iSG Box SE for flashing.

6. Once FactoryTool detects the connection, it will begin flashing the OS. You can release the reset button once the process starts.

## 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://kb.linknlink.com/isg/settings/system-updates/flashing-os/flashing-os-for-isg-box.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.
