Samsung has been rolling out the Android 4.3 update to devices like the Galaxy S3 and Note 2 for a few weeks now. Usually, the US variants of Galaxy range of devices receive new firmware updates months later that it reaches international version. However, the OEM seems to have mended its old tendency these days. The AT&T Galaxy Note 2 SGH-I317 was blessed with the latest OS update with build version UCUBMK6 starting mid December.

Besides bringing the improvements and features typical to Android 4.3, the new update also introduces Samsung’s security tool KNOX and other tweaks to the TouchWiz UX. The new security features like locked bootloader, Reactivation Lock and KNOX will bring smile to those who wish to make secure use of their device.

In case you happen to be one who likes to try different mods and custom ROMS, you might feel disappointed because currently we do not have a working method to unlock the bootloader and install a custom recovery like CWM or TWRP. However, the good thing is that you can still root your AT&T Galaxy Note 2 SGH-I317 on the latest  Android 4.3 firmware and enjoy root apps. You’ll also be able to flash custom ROMs by installing the SafeStrap Recovery.


The root method for AT&T Note 2 has been tested successfully yet we do not hold any responsibility in case you end up in a mess. Follow the guide at your own risk.

Unable to Get Root Access While Being Rooted?

Read this Tutorial to Fix the KNOX Issue


  1. Sorry, does not work on my phone. I keep getting a Security Notice that says “Unauthorized access to secured area has been blocked”. It only does this when I enable SuperSU to be on. If I turn it off then I stop receiving security notifications. How am I suppose to get past this KNOX crap?

    ATT Samsung Note 2 4.3

      • On the Att Note 2, you are unable to access KNOX. The phone will show that you have it when you look at the application manager but in the app drawer their isn’t a physical icon. No way of disabling KNOX per the guide you directed me to… I don’t know what to do. I just wanna use my PS3 controller to play SNES9.

          • Just so you know Rakesh. I followed your directions above and had to do the extra tutorial installing a APK installer. I installed the new SuperuserAPK. It told me I could not run because I had blocking of other than android play apps but, it had the settings button at the bottom. I was able to go into settings and uncheck a couple things and it ran FLAWLESS. I’m same as the above user! SSN2 I317 Running 4.3. THANK YOU THANK YOU THANK YOU!!!! unrelated note: Am I able to back down my firmware to 4.1.1 without turning into a brick now that I’m rooted?

          • Hi, I am glad to know that you could root your Note 2 using our guide. As for downgrading, the new firmwares have secure boot and therefore you would not be able to go back to 4.1.1.

          • Just wanted to say I did the official upgrade of my note 2.i317 from 4.2 to 4.3 and my phone has had nothing but issues. MY only option was to root and try a different rom. Your tutorial has been a life saver. (There was nothing wrong with my phone before the 4.3 upgrade). Now I am able to use a rom and my wifi is working again, among other things. Thank you thank you.
