This update contains a new bootloader due to which downgrading to previous stock firmwares WILL NOT BE POSSIBLE. As of yet, root CAN NOT be retained or acquired on this build (N900AUCUCNC2). Warranty may be void of your device if you follow the procedures given on this page. You only are responsible for your device. We won’t be liable if any damage occurs to your device and/or its components. Before you begin with the instructions below, make sure your android device is adequately charged — at least 50% battery of the device. To make sure your device is eligible with this, you must first confirm its model no. in ‘About device’ option under Settings. Another way to confirm model no. is by looking for it on the packaging box of your device. It must be SM-N900A! Do not use the procedures discussed here on any other Galaxy NOTE 3 (including the Galaxy NOTE 3 variant at Sprint, Verizon, US Cellular, T-Mobile and other International variants) or any other device of Samsung or any other company. You have been warned! Back up important data and stuff before you start playing around here as there are chances you might lose your apps and app-data (app settings, game progress, etc.), and in rare case, files on the internal memory, too. For help on Backup and Restore, check out our exclusive page on that linked right below. ► ANDROID BACK UP AND RESTORE GUIDE: APPS AND TIPS NOTE: Skip this step if you’re already on stock N900AUCUBNB4 firmware with no root and no custom recovery installed. However, if you’ve installed the previously leaked Android 4.4.2 update on your AT&T Galaxy NOTE 3 then you’ll need to revert back to N900AUCUBMJ5 (aka MJ5) firmware first and then take the OTA update to NB4 firmware. It’s required that you are unrooted, and don’t have a custom recovery (CWM or TWRP) installed. Plus, no custom firmwares, either. So follow the link below for instructions on how to revert back to the MJ5 firmware. The link below also has instructions to root the MJ5 firmware, but you make sure that you don’t root your device. Just install the MJ5 firmware, then take the NB4 firmware OTA update and then follow the rest of the guide below to install the N900AUCUCNC2 OTA update on your AT&T Galaxy NOTE 3.   (Don’t root it!)  INSTALL ANDROID 4.3 MJ5 FIRMWARE Download the firmware file given below. DOWNLOAD LINK | File name: 2400258.cfg (554 MB) Important Note: Backup important files stored on internal SD card of your device, so that in case a situation arises requiring you to do a factory reset after flashing the leaked firmware, which might delete internal sd card too, your files will remain safe on PC. That’s it. You’re done. Let us know in the comments below if you need further help with the guide above. We’d be happy to help.LEAKED FIRMWARE INFO
