# 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/)).
