Galaxy S7 (Sprint MVNO) Gloabally Unlocked Firmware Update Loop?

When activating my Samsung Galaxy S7, I can get past everything but the firmware update, where it says "Checking firmware with server" or something along those lines, then I have to reboot. It does this every boot, and I was able to see if I could call or text one time before it rebooted, and I could. Thank you very much for any answer! (This thread is also located at other websites )
