[HOW-TO]Enable Band 4 AWS on SM-N900V
This procedure requires root. I take no responsibility if you mess something up.
1. Enable access to ServiceMode by editing ("Open with Text Editor")
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
to enter ServiceMode
UE SETTINGS & INFO,
then SETTING, then select SYSTEM, then NEXT PAGE and then select VZW LTEB4 ON/OFF and finally select B4 ENABLE ()...It should change to 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 use *#0011# from the dialer
***EDIT 2/7 - Band 4 is now enabled on the MJE update by default.
It's no longer necessary to do this, unless you are still on MI9 or MJ7 or want access to the service menu.
