Switching Carrier:

Disclaimer - Switching Carrier will not carrier unlock your device. For carrier unlock, call carrier or pay for unlock service.

***Note - If you have updated to the V3 Bootloader, N950USQU3BRA?, for any carrier, Prince Comsy's Odin is not blocked - End Note***

Note - This guide uses adb, regular Odin, Prince Comsy's Odin, Canadian XAC Home_CSC, and Factory Binary.

Download Firmwares that match your intended carrier's product code, ATT, CCT, SPR, TMB, USC, VZW, XAA, or XAS.

Make note that Firmwares based on SM-N950U1 are Unlocked Firmwares and do not contain carrier files even though they have carrier code. For Carrier versions, download SM-N950U Firmwares.

Some carrier features may not work on different carrier devices without modifications or having IMEI added to intended carrier's whitelist.

**Note: This will NOT change the CSC Product Code of the device, it only allows you to change carrier Firmware effectively...for instance, XXX/XXX/SPR**

Match Binary version to your Firmware Version as older binaries do not work with newer firmware..

If you are just flashing Carrier Firmware on SM-N950U1, skip to Flashing Carrier guide. If you are just flashing Unlocked Firmware on SM-N950U, skip to Flashing Unlocked guide.

*Downloads are in OP*
