Update: Root is available for Note 4 SM-N910U also now, after its Android 5.1.1 update was released a day ago (build N910CXXU1COH4). This method is confirmed to work for International Galaxy Note 4 sets, model no. SM-N910F, SM-N910G and SM-N910U. And, we’ve added one more custom kernel, so that you have choice.

Original: Root isn’t new for Samsung Galaxy Note 4, but on Android 5.1.1, you need a custom kernel for root to be applied successfully.

Luckily, recognized developer Phil has come up with one, and all you need to root your Galaxy Note 4 on Android 5.1.1 now is flash the kernel via TWRP, before flashing the SuperSU file to root it.

So, you need to have Note 4 TWRP recovery first. Then you have to use the TWRP to flash the root-supporting kernel and the SuperSU file to root your Note 4 on Android 5.1.1 kernel. Let’s see this all in detail now.

Backup important files stored on your device before proceeding with the steps below, so that in case something goes wrong you’ll have backup of all your important files. Sometimes, Odin installation may delete everything on your device!

Step by step Guide

Step 1. Download the kernel and SuperSU file from above.

Step 2. Transfer the kernel and SuperSU file to your LG Galaxy Note 4. Remember the files’ location.

Step 3. Boot your Galaxy Note 4 into recovery mode to access TWRP recovery.

If you don’t have TWRP already, check out our page on Galaxy Note 4 TWRP recovery and install it first.

Be sure to transfer the kernel file (both of the kernels, no harm) and SuperSU to device, and then install and boot into TWRP to flash anyone of the kernel of your choice, and the SuperSU file, right after installing TWRP.

Step 4. On TWRP recovery (v2.8.6.0 or newer), tap on Install > locate the kernel file and tap on it. Then do the Swipe action at bottom to begin flashing the kernel.

→ Also install the SuperSU file just the same way.

Step 5. → Also install the SuperSU file just the same way.

Step 6. Once you have flashed kernel and SuperSU, simply restart the device by tapping on Reboot System button that you get on screen after flashing is done.
