How to root the Samsung Galaxy Note 3
Step 1: Head over to this thread
on XDA forums and download the CWM recovery meant for your variant of
the Note 3. Make sure you are downloading the correct version, otherwise
you will end up bricking your handset. Also, download ODIN from here and the SuperSu ZIP package from here. Transfer the SuperSU ZIP file to the root of your Note 3′s internal storage.
Step 2: Extract the contents of the ODIN ZIP file on your desktop. Do not extract the CWM recovery file. The file must end with a .tar extension.
Step 3: Download and install the required USB drivers for your Samsung device. You can skip this step if you have KIES installed on your PC.
Step 4: Put your Galaxy Note 3 into Download mode by
switching it off, re-inserting the battery, and then simultaneously
pressing the Volume Down + Power button. Skip the custom OS warning by
pressing the Volume Up button.
Step 6: Once the drivers have been installed, ODIN will detect your Note 3 and automatically display a random number inside the COM Box. Now, press the Start button and wait for ODIN to flash the custom recovery.
Step 7: After the recovery has been flashed, your device will automatically reboot. Now put your Note 3 into Recovery mode by switching the device off, re-inserting the battery, and then simultaneously pressing the Volume Up + Power button.
Step 8: Once the device has booted into CWM Recovery, select the ‘install zip from sdcard’ option. Then select the SuperSU zip file and install it. After the zip file has been flashed, select the ‘reboot system now’ option to go back into Android OS.
Download the root package you need from the XDA Developer’s forum and save it to your Desktop. At present, there are packages for international versions or T-Mobile and Sprint in the U.S.
2. Extract the .zip file.
6. Plug in the device via USB.
7. In Odin, click Start and wait for it to finish. The device will reboot and you’ll be all set.
