Chainfire's CF-Root has been a phenomenon in amassing an overwhelming eight million downloads spread across various Android devices within a span of just over a year. The device iterations include Samsung Galaxy Tab, Galaxy S, Galaxy S2, Galaxy Nexus, Galaxy Note and Galaxy S3. The Samsung Galaxy Note 2 is the latest entrant to the CF-Root party, owing to the efforts of XDA Elite Recognised Developer Chainfire for adding yet another leading device to the kitty.
According to XDA Developers, the new iteration of CF-Root, also known as CF-Auto-Root, comes with some key features: bug-fixes for broken cache partitions during rooting, besides fixes for Triangle Away and Mobile ODIN. The CF-Auto-Root is a one-click flash tool which automatically installs root and then returns your device to the stock recovery. This feature comes in handy for installing OTAs and certain DRM-style apps.
Key Points to Note

- Ensure that you have a Windows PC with Galaxy Note 2 USB drivers installed on it before proceeding with the CF-Root procedure.
- Download Galaxy Note 2 USB drivers for 32-bit Windows from here and 64-bit Windows from here. Install the drivers manually and follow the onscreen instructions.
- Verify that Samsung KIES software is disabled or completely uninstalled to prevent unexpected system interruptions while rooting the device.
- The instructions provided in this guide are meant for reference purpose only and do not cover any warranty claims involving device damage or issues arising out of using the CF-Root tool. Users are cautioned to proceed at their own risk.
