The same CF-Auto-Root tool by Chainfire has given millions of owners root access to the internal system for many years. The way it works has changed over time as Google change the Android security from different versions of Android. The jump from Android 5.1 and above on Samsung devices uses a systemless root method which doesn’t require any modifying of the system partition. Everything older than Android 5.1 has to modify the system partition. Rooting methods that modify the system partition make unrooting more challenging than the systemless versions.The systemless root can unroot just by taking a factory reset from the recovery mode whereas the method that uses the system partition needs to have a stock ROM flashed or the unrooting must be done from the SuperSU application.
- Chainfire was running on the LRX21V.N9006ZCUGPA1 firmware build number when he developed the rooting file for the Samsung Galaxy Note 3 SM-N9006 running on Android 5.0 Lollipop.
- You must have a computer that is running on Windows operating systems to use this guide because the Samsung smartphones always use the Odin flashing tool to flash the CF-Auto-Root one-click rooting tile. You won’t get the Odin flashing application to run on anything other than Windows.
