# Force Update

Sometimes you may need to update the software even if you cannot enter iSG due to critical issues. In such cases, you can perform a **force update** through the Android system. This process does **not** require logging in, and in some cases does **not** require a network connection.

The force update method only applies to **iSG** and **Container** software.

### 1. Download APK File(s) to USB Drive

Download the required APK file(s) to a USB drive. Please refer to [**iSG Downloads**](/isg/settings/system-updates/local-update/isg-downloads.md) and [**Container Downloads**](/isg/settings/system-updates/local-update/container-downloads.md). It is recommended to verify the MD5 checksum of the files before updating.

### 2. Access File Manager

To perform a force update, you need to access the system’s file manager app.

#### On iSG Box:

Press the **Settings** button on the remote control. The system menu will appear on the right side. Navigate to:\
**Apps > See all apps**, then locate and open **File Manager+**.

#### On iSG Display Max

Long-press the **Power** button on the back of the device and select **Settings**. Then navigate to:\
**Storage > Documents and other**.

### 3. Install Update

Find the update file (APK) on your USB drive and select it to launch the installer. When prompted, choose **Package Installer** and select **Always**.

## 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/force-update.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.
