This thread is now completely dedicated to the aspect of Carrier Switching on the Snapdragon model of the Galaxy S8/S8+, the current root progress can be seen here:
Current ROOT Progress for G950U/G955U Snapdragon


Please Note that if your device is network locked this WILL NOT unlock it for use on other carriers, however it will allow the switching of carriers and carrier specific features on network unlocked devices just by changing sim cards, the device will reboot and your done. As for those with a network locked device this thread still applies to you, if you are interested in a bloat free experience(that is faster and smoother than stock touchwiz), on your Galaxy S8/S8+


Let's Begin!
  1. Download the firmware for the unlocked S8/S8+ here:
    G950U1UE1AQDC_XAA
  2. Download the Prince Cosmy version of Odin here:
    Odin_3.12.3_Modified
  3. Enable developer options on your device:
    Settings----->About Phone----->Click Build Number 7 times
  4. Enable USB Debugging:
    Settings----->Developer Options-----USB Debugging
  5. Put your device into download mode: Volume Down + Bixby + Power
    (accept the warning and connect your device to your computer)
  6. Take the G950U1.zip you downloaded in step 1 and extract it, then place the BL,AP,CP,and CSC files into their corresponding places within Odin and press start
  7. Once finished the device will boot back up and you will be free to disconnect it from your computer
  8. You now have the unlocked, bloat free, firmware on your S8/S8+

Oh, ok. Didn't realize that. So does this overwrite the carrier info? Or is that untouched?

As of right now there is no way to overwrite carrier info, we are working on it though. That reserved comment is going to be where i put all that is known, been tried, etc with carrier switching just a little busy right now

My build number is SM-G950A and my firmware is G950USQU1AQD9. I am quite familiar with the concept and process of rooting but I have never had an opportunity to actually get into it. I was wondering if my device is compatible with this firmware. If so I am fine with testing so long as there is a reliable way to restore my phone if something were to happen.
