Tutorial to Unlock Sprint Galaxy Note 3 For T-Mobile/AT&T/MVNO's
Tools required:
Hidden Menu Enabled(modified for galaxy note 3): http://goo.gl/y4k2EG
MI3 modem (modified to be flashed via odin): http://goo.gl/W0f3Za
Odin 3.07 or 3.09 (google for it theres a million mirrors of it)
Device must already be internationally unlocked via sprint for this to work (must perform uicc unlock from system updates menu) im working on a way to do this without sprint but for now this is how it is)
Region Lock Away: (Free on chainfires thread or consider buying market donate version) http://forum.xda-developers.com/show....php?t=2470551
Device must be rooted: (rooting via this method will trip knox however the modem flash we have to do will likely trip it as well): http://download.chainfire.eu/362/CF-...pr-smn900p.zip
Any root browers from play store
ServiceMode Shortcut: Grab from play store
prl helper or anything with an apn shortcut: Grab from play store
Step 1: We need to root the device so put device in download mode holding vol down+home+power while it is off. Flash cf auto root to obtain root (this will void knox).
Step 2: Grab a root browser, ServiceMode Shortcut, PRL Helper, and Region Lock Away and install your att/tmobile sim.
Step 3: Place device back into download mode. PAY ATTENTION HERE: you need to add the mi3 modem to pda and uncheck auto reboot. LEAVE ON F. RESET TIME CHECKED. After flash has completed remove battery from your phone place it back into download mode and flash mi3 modem again this time leaving auto reboot checked. When your device boots up to to settings->general->about device and check your baseband version to make sure it ends in mi3. if it does not redo step 3.
Step 4: Run regionlock away (not required for this all to work just for good measure), And switch your device into gsm/umts only mode in your settings menu.
Step 5: Plug your device in and enable usb debugging. run hidden menu enabler. open TestMode Menu. Follow these steps perfectly.

11. go all the way back to main menu. hit protocol state, sim information, check nv, and make sure it shows sim lock is disable, spr bip unblocked, and sha256 on or off shouldnt matter. ( i have had mine off and on and it seems to work either way)(mine is currently on)
12. power cycle device.

16. reboot device once more. now use prl helper or your apn shortcut and create a new apn for your carrier. delete all the sprint ones and make sure you highlight the circle next to your newly created apn. reboot once more.
17. device should come up with full service bars and data/mms active. (if you have an inactive sim card it does not always show service)(my inactive att card would show service my inactive tmobile would not)
18. Donations appreciated now you should be 100% unlocked. if you need to undo this for any reason see post 3 to get fully back on sprint.
