    Default [HOW-TO] Enable Band 4 AWS on SM-N900V *REQUIRES ROOT*

    This procedure requires root. I take no responsibility if you mess something up.

    1. Enable access to ServiceMode by editing ("Open with Text Editor")

    /efs/carrier/HiddenMenu file

    with a program like Root Explorer, and changing it from OFF to ON (uppercase only). Reboot the phone.

    2. Once the phone is rebooted, enter the dialer app and input

    *#27663368378#
    to enter ServiceMode

    3. Select:
    [2]UE SETTINGS & INFO,
    then [1]SETTING, then select [2]SYSTEM, then [9]NEXT PAGE and then select [4]VZW LTEB4 ON/OFF and finally select [1]B4 ENABLE ()...It should change to [1]B4 ENABLE (*) with an asterisk. Reboot the phone.

    AWS Band 4 should now be enabled for your Galaxy Note 3.


    To force the Phone onto Band 4:
    Enter ServiceMode, UE Setting > Settings > Protocol > NAS > Network Control > Band Selection > LTE Preference > B4. Do this at your own risk. When Band 4 is forced it is Data only, No voice. To switch back to automatic do the same thing, but choose Automatic instead of LTE Band Preference.


    To view what band your Phone is operating on:
    Enter ServiceMode, Protocol State > Basic Information .. it will show on the first line.

    You can also monitor your band by dialing *#0011#

    How do you enable the Service mode? I can't seem to find it on my Note 3 (N9005), thanks.

    Dont know about N9005 but on SM-N900V it must be enabled first by using a root explorer to change

    /efs/carrier/HiddenMenu

    from OFF to ON before the codes will work in the dialer

    My efs file is empty. That doesn't seem right. Also if I'm getting 50 down and 7 up what would be the benifits? To me those speedsseem great. Just curious. Thanks.

    the 'reboot the phone' touch screen option in the band-selection doesn't reboot the phone for me.
    Anyone else?
    Doing a manual-reboot to see if the Band4 is now enabled still.

    Update: rebooted the phone manually, checked state - shows LTE B4 Enabled, but I still have voice bars and data (3g in my job warehouse).
    weird.

    Did you usually get a 4g signal in your warehouse? Or, are others on the same carrier gettting one? Someone else with a Note 3 who's done this already would be ideal, but I'm sure I'm asking too much there.

    I can not disable band 4...in service mode I can click on disable but when I hit Restart phone nothing happens and when I manually restart it, band 4 remains enabled. Any ideas?

    I know this requires root.. so is Knox tripped on your devices? I want to do this but can't find a way to root without tripping Knox at this time.

    Kingo was how i rooted, and doesn't trip Knox. Literally took me 15 minutes & i only touched the phone once. Easiest root method i've ever done (including my galaxy nexus).
    As for if this tripped Knox, i'm uncertain

    Have you tried this yet? Worked for me with no problem and didn't trip Knox either. And yes, I'm on MJE.

    Glad you got it to work. If you used the method in the link, you didn't trip Knox, did you? To check, turn the phone off and press power, home, and volume down. This puts you in recovery mode. Look where it says Knox. If it says 0x0, you're good. If you can check and report back here, that would give people confidence in the method.

    I do not see a file for the SM-N900V here: How to Root Galaxy Note 3! | GalaxyNote3Root.com
    Or here: ClockworkMod/TWRP Recoveries | GalaxyNote3Root.com
    I've got a SM-N900V on MJE and Android 4.3
    I've tried a couple different process out there and have bricked twice and had to do a full recovery. The last one required Keis because it would not go into recovery mode. Odin, Kingo... nothing has worked, and I even used De la Vega : Root_de_la_Vega-SM-N900V.7z
    Running Windows 7 with anti-virus turned off and a USB 2.0 cable.
    Odin fails, and Kingo just never downloads the files.
    I eventually have to unplug and restart the phone, which puts it into a "Firmware upgrade encountered an issue" condition.
    If I could confirm anyone successfully rooting with my configuration I'd be happy to hear about it. Or, is my config included in the successful roots above, but just not mentioning SM-N900V specifically?
    Thanks!


    I just tried this method: http://galaxynote3root.com/galaxy-no...galaxy-note-3/
    using n900-cwm-recovery-6.0.3.8(0926) and my screen shows:
    ODIN MODE
    Product Name: SM-N900V
    Current Binary: Samsung Official
    System Status: Official
    Knox Kernel Lock: 0x0
    Knox Warranty Void: 0x0
    Qualcomm Secureboot: Enable (CSB)
    AP SWREV: S1, T1, R1, A2, P1
    Write Protection: Enable
    SYS REV CHECK FAIL: No Version
    SECURE MAGICCODE CHECK FAIL: recovery
    I was able to power off the phone and bring it back up without a brick

    I'm about ready to give up on this thing.

    Hello, I would like to comment that this method functions also flawlessly with the Verizon S5 too, I tried mine and I am enjoying LTE abroad.

    Is there a way to turn it off and go back to lte. I think we are finding out now that data is horrible after Verizon turned it on

    Must not be able to turn it off. I followed process, turned it off, restarted phone. Checked and it is still on.

    This is what it says when I check the status when I use the code provided by OP. If I go thru the secret menu process again after restarting the phone, B4 is checked active again. Seems restart reactivates B4.
