when updating past 4.3 you aquire the updated bootloader and can no longer "safely" downgrade to 4.1.1 to unlock this phone. however if you:

1) Root the phone and allow SU to disable knox
2) Install custom recovery (TWRP, CWM, OR OTHER)
3) Boot into recovery and flash the atti317ucalj2modemfixed.zip modem
4) After reboot you can use this method to unlock:

(From this thread http://forum.xda-developers.com/show....php?t=2014982)

Just dial the following keys *#197328640#

Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF > (after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in [6] Network Lock then choose [4] NW Lock NV Data INITIALLIZ ..... wait for a minute then reboot your phone... enjoy your unlocked phone!!!

5) Reboot recovery and flash the newest modem I317_ucucne5_modem.zip
6) Reboot again and enjoy your fully unlocked 4.4 note 2 att with out losing your data or bricking your phone

************* non at&t notes try using earlier versions of your own stock modems then updating after unlocking ************ @umaza has infomed me this method Seems to have worked for 4.4.2 i317m Koodo, just downgrade to the Rogers Modem,
Go here (http://forum.xda-developers.com/show....php?t=1987541) , go to Section 3, and go to Rogers, and get "I317MVLALJ2....uploaded by DAGr8 (Direct Link)"

With all due respect to OP and his lack of posts (like I have room to talk, right? ) can anyone else verify this as working before I attempt this? I need to unlock my phone and would rather do this than flash 4.1.1 (and trip Knox) and then reflash to a 4.4.2 ROM.

the other posted method works for previous software, the method has to be tweaked to work on 4.1.2 and above. im guessing people arn't reading that part of the post just assuming this is the same unlock method that use to work with out flashing the modem. they removed the #4 prompt in network lock on the newer modems so you cant manually unlock them.

send me your model, current version, baseband etc and i will help you figure it out. you shouldn't hit send in the dialpad to access the hidden menus. apon hitting the last # it directly loads the hidden menu.
