Can you jailbreak a handheld device like the Samsung GalaxyNote 2 running on Android Jelly Bean Firmware? You certainly can, but with android devices, it is called rooting, and is perfectly legal.
How do you know what Galaxy Note 2 version you have? There are at least 3! Open your Galaxy Note 2, press settings, scroll down to ‘About Device’, and you’ll see an option labelled Model number. If it’s GT-N7100, you’re good to go for the steps on this page.
WHAT IS NEEDED
Before we begin with rooting/jailbreaking, simply download the following packages:
- Download the rooting code for the GT-N7100 flavour of the Samsung Galaxy Note 2 N7100 Android 4.11 version.
- (for the Galaxy Note 2 GT N7105 LTE Android 4.12, the rooting code is cwm6-root-n7100-121015.rar). Only choose this or the previous one, depending on your version of Android OS as seen in sample above.
- Download Odin3-v3.04.zip to your computer. This one you need to extract. Extract the zip file to obtain Odin3 v3.04.exe.
- Some users noted that the older Odin versions for rooting do work, too! So Download ODIN v1.85 which is needed to root Android 4.1.1 firmware if you prefer.
- Samsung Galaxy Note 2 USB drivers for Windows, if you are running Windows, or the drivers for Mac or Linux if you are running those. Install the drivers if you haven’t installed them already
- Make sure that your phone battery holds at least 70 to 85 percent charge to avoid unexpected device shutdown while flashing the ROMs or rooting the Jelly Bean firmware.
Step by Step How to root / Jailbreak Samsung Galaxy Note 2 GT-N7100
Before you can root/jailbreak, you need to Install CWM Clockworkmode.
How to Root / Jailbreak Samsung Galaxy Note 2
Step 1: This is actually downloading the four files above and preparing them for use: Galaxy Note 2 GT N7100 rooting code, Odin 3.04, Samsung USB Driver.
Step 2: Check to see that USB debugging (under Settings -> Developer options) is enabled in your phone, then turn Off your phone and just remove and reinsert the battery
Step 3: you’ll want to allow your phone to install non-Google Play apps, and run debugging mode when connected via USB. On your Note 2, select Settings > Security, and you just have to scroll down to Device Administration and tick ‘Unknown sources’ in the menu
Step 4: Run the ODIN application on your PC which you downloaded in step 1.
Step 5: Connect your device to your computer using the USB cable. If you have completed the above steps the Odin window will show that the device has been detected otherwise it will not respond, and you will have to redo since Step 1.

Step 6: Run Odin, and make sure that ‘Auto Reboot’ and ‘Reset Time’ are ticked. Unzip the CF-Auto-Root-t03g-gtn7100.zip file that you previously downloaded you’ll find an identically named file inside the zipped file. Return to Odin and press the PDA button and select the aforementioned .tar.md5 file.
Step 7: Get your Samsung Galaxy Note 2, and turn it off, essentially doing a reboot. Now reboot it into Download Mode: you do this by holding down the volume down, home and power buttons at the same time. You’ll be presented with a screen with some warnings about custom ROMs — you know the risks already, so press volume up to continue. It’ll change to a screen that says ‘Downloading…’ with a big green Android icon on it. Plug it in to your PC via USB and return to Odin.
When you connect your phone, the message box in the bottom left hand corner should (rather enthusiastically) say ‘Added!!’ when it spots your phone is connected. When it prompts for the time to root, press the big ‘Start’ button in the top right-hand side of the screen.
This only takes seconds on a Galaxy Note 2, and then the phone will reboot itself.
