Steps to Root Galaxy Note 2 N7100 Running on Android 4.4.2 KitKat Stock Firmware and Install Philz Touch Recovery
- Copy the SuperSU update.zip file to your Galaxy Note 2.
- Now power off your phone and boot it into the Download Mode by pressing and holding Volume Down, Home and Power buttons together. Hold the buttons until the screen powers on and the warning screen appears. Then tap Volume Up key to enter Download Mode.
- Open the Odin folder and launch SuperSU.
- Now connect your device to the computer via USB cable.
- Wait until the "Added!" message appears in Odin and the ID:COM box turns light blue.
- Click the AP button and choose philz_touch_6.26.6-n7100.tar.md5 file.
- Uncheck the Auto Reboot option on Odin.
- Now hit the Start button to begin root installation.
- Wait until the installation completes and soon a PASS message with green background should appear in Odin. PhilZ CWM recovery has now been flashed to your phone.
- Now unplug the USB cable, remove the back cover and take out the battery.
- Wait for about 30 seconds before reinserting the battery.
- Now boot the device into recovery mode. Press and hold Volume Up, Home and Power keys together until the display turns on and the Samsung logo flickers and disappears. Now release the Power button but continue holding other keys till your Note 2 boots into PhilZ recovery mode.
- Browse to Install zip from sdcard option, navigate to UPDATE-SuperSU-vx.xx.zip and select it.
- Confirm the installation and when the file is flashed to the device, return to the main menu in recovery.
- Hit Reboot system button once the root installation is complete.
Your Galaxy Note 2 will reboot. Wait till it boots to the home screen and then go to the app drawer. Check for SuperUser app there and launch it. As Note 2 comes preinstalled with KNOX on it, you might see the following message:
"Samsung Knox has been detected. This might limit root capabilities and cause annoying popups. Try to disable KNOX."
Hit OK. You will now see the message KNOX has been successfully disabled. To further verify root access, download and install Root Checker app from Google Play store and run it.
Troubleshooting (courtesy XDA Developers)
Problem#1: If you keep getting SuperSu has stopped notifications constantly then follow these steps to fix:
- Uninstall SuperSu (Dont worry you won't lose root access)
- Now download SuperSu again from playstore
- Doing this installs SuperSu on /data/app partition where it won't get stopped by KNOX
Problem#2: If Fix no1 doesn't work for you then try this out:
- Download Terminal Emulator from the playstore.
- Launch it and type the following code:
pm disable com.sec.knox.seandroid
Note: This will disable the Knox apps which prevent SuperSu from running
Problem#3: If none of the above steps work to disable Knox. Then try the following:
- Using any Root Explorer go to /system / app & / system / priv-app and delete all the apps having the word Knox in it. Also delete their corresponding odex files.
- This should work without fail. But doing this modifies your system partition and you may lose OTA functionality temporarily.
