- The rooting package made by Chainfire found in this guide is based on Android 4.0.3 Ice Cream Sandwich and IML74K.P5110XWALD2 firmware. You don’t need to flash the firmware that has the same build number on your Samsung Galaxy Tab 2 before you use this guide.
- You must have a computer that is running a Windows operating system to get this guide to work. The Odin flashing tool does not work unless your computer is running Windows; therefore you cannot expect the guide to work without Windows.
