Root Galaxy Note 2 N7100 on Android 4.3 Bypassing Knox Warranty Void Bit

The Android 4.3 Jelly Bean update for Galaxy Note 2 brings Samsung Knox security protection, which was introduced in the current Galaxy Note 3.

Users can activate Samsung KNOX, which allows running and storing security-sensitive applications and data inside a protected execution environment called container.

The security inside the container is strengthened by system-level protection of Samsung KNOX against malware and phishing attacks as well as hacking attempts on physical devices when devices are stolen or lost.

XDA developer k1mu has released a root exploit without tripping Knox warranty void bit. This root exploit works on a number of Android-powered devices. It does not void the device of its warranty but sets the custom flags. Besides, the root exploit package installs su, SuperSU and other necessary support files to enable the root.

This rooting process should work with a wide range of Android devices, particularly those running Linux Kernel before 3.5.5 (which most Android 4.3 ROMs use.) It's known to work for may GS4 variants and is harmless if it fails to work (no "Warranty Void" flags get set.), notes the developer. Head over to the development thread to learn more about the root release.

Galaxy Note 2 users, who wish to root their devices, may follow our step-by-step guide below.
