Rooting your Samsung Galaxy Note offers you a lot of advantages, as it unlocks a lot of new features, customization options and allows you to install more apps. The process is relatively simple, but you may need to downgrade your device to an older Gingerbread version if you are running a more recent one.
Before we start the root process, please check what firmware you are currently running. Here is the list of firmware versions that can be rooted directly: XXKJ1, ZSKJ6, XXKJA, XXKJ, JPKJ4, XXKK3, XXKKA, JPKK2, XBKK4, DXKK1, ZSKK1, DXKK1, XXKK9, XXKKA, DXKL3, DXKL1. If you are running one of these, then you can proceed to the rooting process. Otherwise, go on and follow the steps to downgrade your Samsung Galaxy Note to an older ROM.
While downgrading your device, you might lose your data, so make sure to perform some backups.
Backup your Galaxy Note
To backup your contacts you should sync them with your Gmail account.
Backup your SMS messages with the SMS Backup and Restore. If you want to restore your call logs, you can use Call Log Backup and Restore. You can copy your files to the either internal or external SD card, so that they won't get deleted during the update.
Downgrade Samsung Galaxy Note to KJ1 ROM
First you have to download the KJ1 ROM here. Then download Odin 1.85 and launch it.
Extract the downloaded KJ1 file and you should see a .tar file. Make sure your device is disconnected from the PC and that it's charged to at least 50%. Now click "PDA" in Odin and select "SGN_XX_OXA_KJ1_FACTORYFS.tar".
To make sure your computer recognizes the Galaxy Note, you will have to go to Developer Options and make sure that USB Debugging is checked.
Now you will have to reboot the Galaxy Note in download mode. So turn off the device and then press the volume down + home + power buttons simultaneously to boot in download mode. When you see the green Android, press the volume up key. Now you can connect the device to your computer using your USB cable.
Once your device is connected to the PC, a yellow ID:COM box should appear in Odin. If it doesn't, install Kies on your computer and it should now work.
If everything is ok, make sure you did not check anything else in Odin and that Kies is closed, then press Start. After Odin flashes KJ1 on your Galaxy Note, you should wait for the device to reboot twice and then you are done.
Root Samsung Galaxy Note N7000
Your will first have to check which Kernel is your Galaxy Note using. If you downgraded it earlier, then it should be KJ1. Otherwise, download the proper file from the following list: KJ1,KJ4, KJ6/KJ7/KJ8, KK1/KK2/KK3/KK4/KK5, KKA, KK9, KL3, KL1. If you don't know how to check what kernel you are running, go to Settings > About phone > Kernel version. You will see a name like this one "188.8.131.52-N7000XXKJ4-CL641703." In this case the kernel is KJ4 and it's the only part that matters.
Extract the file, make sure you have USB debugging enabled and the latest Samsung USB drivers installed on your computer. If you don't, then install the last version of Kies. Now you can connect the Galaxy Note to your computer, run not-rooted-yet.bat and press any key to start the rooting process. In a few minutes you should have a rooted Galaxy Note.
Now your Galaxy Note N7000 should be rooted and you will have to upgrade it to either a newer Gingerbread or Ice Cream Sandwich ROM.
