How to root Samsung Galaxy Note II GT-N7100 (or GT-N7105)? In short, it is not hard at all. Samsung Galaxy Note 2 has an unlooked bootloader. So you can modify it easily including rooting. For me, root access is a must have for Android devices. So I don’t buy product with locked bootloader usually. Root access is great because you can do lot of interesting stuffs like backup applications and data with Titanium Backup, remove advertisements, improve user experience with custom modification… Interested to root Samsung Galaxy Note 2? Just watch my step by step video guide to learn how to root Samsung Galaxy Note 2.

Hi nars, please restore back to your previous CWM backup. Chainfire3D can’t work on Galaxy Note 2.
Great step by step guide with video 🙂 thanks!
Rooted and works, now i can play games with my ps3 controller, how cool this is?!
Yep, tested it last night and pad works also in menu/”desktop”
I wonder, if i want to “unroot” my note2, simply just search for original firmware xxx.tar.md5 and same steps?
First factory reset and after that put orig. firm with ODIN? Could that be so easy, maybe i need to try… little guide would be nice 😉
//I´m a little stubborn (:
Elsewhere i read that updates via OTA is possible with “Voodoo OTA ROOTKeeper”, that temporarily unroot phone with just one click for updates…
Yes, factory reset first then install stock firmware back. Note – you might want to Triangle Away to clear the ‘warranty’ counter.
What is thr warranty counter?
Something like this…

will the counter increase?
Jayce, Great Website. I just bought my device a couple of days ago. It’s a Model Number SPH-L900. Is there anyone out there you know that has been able to root this model?
Hi Arnold, yours is Sprint version, right? If yes, please refer to this guide.
I just got note 2, any idea how to move apps or file to sd card?
Hi Simon, you can use Directory Bind.
will this root procedure the same with note 2 gt-n7105? will it work with it?
follow up question, ive installed perseus kernell and it has stweaks in it, do you have the settings for overclocking and undervolting?
thanks jaycee, by the way i havent installed the CWM, is it ok if its not installed? will it have negative effects on my rooted phone?
It is okay not having CWM. No negative. But recommended to install because you can make a full system backup of your phone.
i would but it seems the cwm available right now is for GT-N7000 only, for GT-N7105 is not yet created ^^, ill install it once there is one for my phone ^^, thanks for the info again ^^
I have rooted my Samsung Galaxy Note II but found both USB and Wifi tethtering not function could it be the rooting problem or my Note II problem, by the way do you have this issue with your Note II . If its rooting problem how to do the recovery with original firmware ? And how to reset the factory reset counter ?
Root access does not have any effect on these.
Use Triangle Away to reset counter. Factory reset. Then install original firmware with Odin.
Do you have any link how to use triangle away to reset counter tutorial ?
I don’t have Galaxy Note 2 guide yet. But you can refer to Galaxy S3 guide. The process is the same.
Do you have Note II N7100 XXALJ3 Firmware download link ? I couldn’t find this download link in your blog .
You can get it from SamMobile.
thanks for the video instruction on youtube, i have a few questions that needs answer before i try rooting my Samsung galaxy note 2.
My samsung galaxy note 2 model is N7105, Android 4.1.1, baseband version :N7105XXALJ2 (is this what so called samsung stock ROM version?)
Build number is : JRO03C.N7105XXALJ5
Do i just need Odin3 v1.85 (or version 3.04?? ) and CF-Auto-Root-t0lte-t0ltexx-gtn7105 to get the phone rooted?
Do i need to install cwm 6 recovery? where to get it for N7105?
thank you so much Jayce,
Hi Andy, both Odin version should work just fine. Yes, that’s the one for N7105.
Install CWM or not is totally depend on your need. You can refer to the link in the guide to get it.
Thank you Jayce.
Can rooted samsung galaxy note 2 get a firmware updates automatically online? Like the upcoming jelly beans 4.1.2? How about other apps get updates too?
No with OTA, but you still update it with Samsung Kies.
So after update through kies my root will be gone and have to root it all over? Thanks
You will have to root it again.
Just to double check, when i downloaded the cf-auto root from the link that you mentioned, it is a zip file. When i extracted the zip file it is a file.tar.md5
Base on the video tutorial that you posted, i should be selecting a .tar file.
Is the .tar.md5 file same with the .tar file in your video tutorial?
hi..about root use philtouch method
it can remove triangle or not for permanent?
Yes can remove. Permanent? No because it will increase counter when you load custom recovery.
Great video and instruction, my Note2 is now rooted. Can you give me some basic idea what to do now or what rooted apps to have.
Thank you in advance.
