# 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+**.

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**.
