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

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.

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.
