    Default 4.3 downgrade to 4.1.2 possible?

    Yeah yeah I know, stupid me.
    Anyhow. At+t note 2, upgraded to 4.3 do not like the look/feel of it, plus the additional apps. Not to mention the free wifi hotspot apps no longer working.
    I'm not great at hacking this thing, don't even run that Keis program so that is not an option at this point.

    Any advice here, thanks in advance.

    I don't think there's a way to downgrade OS version unless you're rooted (someone correct me if I'm wrong).

    Maybe via ODIN?

    Let me see if anyone else knows.

    Even if rooted I am not sure that is the case. Knox is in the bootloader as well.

    Yes Knox is in there also. I have read that this kind of screws up the whole thing. Finally get the thing working the way I like it too.

    Not like the good old days of blackberry

    That is correct. You can't downgrade anymore because of Knox
    Root won't do anything because there are still no custom recoveries for the 4.3 firmware

    Found this on XDA developers. Haven't tried it yet

    For people wanting to unlock there Note 2 SGH-I317 but can't due to being on 4.3 MK6 (OTA) or you just hate KNOX and want to kill it here's a guide on how to do so.

    I AM NOT RESPONSIBLE IF YOUR PHONE BLOWS UP, KILLS JUSTIN BIEBER OR BRICKS. DO AT YOUR OWN RISK!!!!

    Ill try to make it as simple as possible with step by step instructions

    STEP 1: Download the 4.1.1 LJ2 firmware from Sammobile and extract to Desktop or somewhere convenient (need and account)

    STEP 2: Download Odin 3.07 or your preferred choice, open Odin

    STEP 3: Put your Note 2 in Download Mode and plug into a RELIABLE usb port and a RELIABLE usb cable (preferably the white Samsung cable) and wait for it to show up in Odin (COM5 or something like that)

    STEP 4: Click the PDA slot in Odin and locate the LJ2 4.1.1 firmware and wait for it to verify, it may look like the program freezes but its just verifying the md5 firmware.

    BEFORE ANYTHING MAKE SURE IN THE OPTION AREA ONLY AUTO REBOOT AND F.RESET TIME ARE CHECKED!!!

    STEP 5: Click START and wait. After a while Odin should say RESET in the BOX above the Option area

    Did you notice that you note doesn't boot after a while?? This is because of left over 4.3 file not letting the system boot. Pull the battery and let the phone sit for a few seconds, pop the battery in and boot into stock recovery (HOLD VOL UP+HOME+POWER) and do a FACTORY RESET then reboot.

    STEP 6: SUCESS!! If you did everything right your phone should boot into 4.1.1.
