Hey guys,
Bought the galaxy s8 plus from a store thinking it was factory unlocked version directly from samsung, but it wasnt. Its the unlocked sprint version based on the radio, and it had a tmobile app or two already installed. I am using AT&T and would like to change the carrier to at&t so that I can get a few features for at&t (Mainly being able to send mms while on wifi). I updated to the latest online update (which im guessing i shouldnt have) and i would like to know if its possible to easily change the carrier still, and or if i can downgrade safely to change the carrier. If so, what files are the latest that I can get the ball rolling with? Using the AT&T version is completely fine.
I came across this youtube video that shows how to easily change carrier without flashing: https://www.youtube.com/watch?v=msAHhCVF-F8
Basically i am a bit lost and would like to know if anyone can help at this point. Here are my software information:
Bootloader Version: G955USQU1AQGL
Build number NRD90M.G955USQU1AQGL
Active CSC Code: XAS
Please advise, thanks guys!

Goto updato.com to download the latest AT&T stock firmware. Extract and flash the files in Odin. If you flash all the files (AP, BL, CP And CSC) you will wipe everything on the phone so backup first. If you don't want to start over, then just flash CP and CSC.
There are two versions, 955U and 955U1. The U version is carrier specific and will contain their own software bloat. The U1 version is unbranded so no carrier bloat.
If you need more details, search for carrier switch.

Hey my friend,
Thanks so much for reaching back with an update and for the support! Awesome! So, youre 100% sure downgrade procedure wont brick the device? Also, do you know if this will this trip knox? Last question: do you think this will solve the red tint on the edges of the phone? I heard this was supposedly a software issue, not hardware.

Ok, so I tried it and with the unbranded XAA version and I am getting a "FAIL! Model dismatch fail" in odin. Even tried renaming files to tar and removing md5 at the end.
I also noticed that when in download mode, there are no green words going across the screen like I see in youtube videos who get it after they connect it. Could it be i do not have specific drivers installed? I installed the samsung usb drivers.
EDIT: Scratch that, the odin PrinceComsy version (Has to have the banner at the top) seems to be working fine. I am currently flashing

Download quick reboot for your phone and use the app to get into download mode. Make sure you have debug settings turned on in phone. Also check if you can access the phone when its plugged into your computer. If you see it as a drive, then the drivers were installed correctly. If not, uninstall and reinstall.

Awesome. ok, so i got it to work. But now when i reflash the rom back for sprint, the splash screen is stuck to AT&T and does not remove or go unbranded no matter what i do. It even has bloatware for att when the system starts. I never flashed att rom, only sprint unbranded XAS, not sure how this is happening. How can i get unlocked gsm and cdma back unbranded for sprint? I even formatted everything and flashed the user data, still the same. Its weird
Also, I am flashing it back to return the phone to store the way I received it. This red tint is just unacceptable.

You need to flash the XAA not XAS U1 firmware.

Yes that firmware is unbranded. The CSC from XAA will automatically detect your carrier's sim and use that network.

Ok, so just tried it and the sprint CDMA is no longer available in the Mobile Networks menu., only the following:
Mobile Data
International Data Roamin
Disable 2G
Access Point Names
Network Operators (AT&T underneath)
There is no option to choose CDMA like there was before I just firmware changed. The XAS firmware that I had offered the option to choose automatic, LTE/3G, CDMA. Now its gone from the menu after the XAA flash.

Hey bud,
Thanks for this. My actual carrier is AT&T, but id like to keep the option of having CDMA available if I ever decide to go with sprint. I have the app installed, When i tried to launch Preconfig (com.sec.android.Preconfig.Preconfig) and it gives an error "su: not found"

Forgot you have to be rooted use the app. There's an adb command you can use instead. Just do a search in xda for preconfig carrier switch.
I flashed my spring s8 plus with Odin and now I can't get it to read my sim at all ,says will not register on network , where the carrier usually is it says 12345 , I've tried to flash back to stock and nothing works ...im at a loss this is my only phone ,I've tried to do a stock reflash and still nothing , I even did a emergency recovery through smart switch and still ...please help
Hello, I have a TMO Note 8 which I have unlocked from Tmobile. I flashed the firmware and carrier to VZW, bought a Straight talk Verizon sim card and service plan but i cannot get any data to activate. I receive the sim saying its active but no data is going through. I cannot change the APN also as it is greyed out. I used shortcut master but will not let me go into apn option to change. Thinking that this is the VZW firmware, i flashed the unlocked XAA but the same problem still persists.
Does anyone have experience in getting Verizon Sim straight talk working on a VZW flashed TMO note 8? I called in and straight talk said they could not add my IMEI for some reason and it has to do with verizon. Im out of ideas. I ported to number to an ATT sim and it works fine with LTE... any help would be greatly appreciated.
When you flash different carrier firmware i believe you still need to change the CSC, the official way with the system app. This factory resets and wipes the phone.
Did you do that yet?

I followed the changing firmware and did change the CSC. It was VZW/VZW/TMB after the first flash. then did XAA for unlock
i cant even get a verizon straight talk sim card to activate lol
I just switched from Sprint to TMB with my Note 8. It is unlocked and working with TMB SIM card. I had some issues with menus etc when I first switched due to the differences between what the two carriers load on the phones, so I downloaded the 7.1.1 software load for TMB from sammobile. Most of it works, some of it doesn't, and I suspect I didn't do it completely right since it didn't wipe my data. So, now I am wondering if my phone will get the OTA Oreo push from TMB, or what I need to do to get it, and have it work correctly.
Thanks for the help!

You'll need to go through that guide for a complete carrier switch. I did it twice for a buddy of mine and it worked perfectly, then you flash stock firmware and it will receive ota's.
Hi XDA haven't been on here for a while.
So I have a question I was given a S9+ from Sprint it's unlocked I'm currently using it on TMO but I don't have wifi calling nor video calling. I wanted to see if it was possible to flash a TMO firmware. Since it's still on July's patch here's a screen shoot of current firmware.
I moved from Sprint to Tmo, and just put in the sim and then updated the firmware through the system update interface. All works as expected.
The difference may (or may not) be, if the phone was unlocked by Sprint or by another method. My wife's phone was unlocked via "another method" and cannot get it to update system software. I haven't bothered looking into it further though, as we don't expect to keep the S9+ too much longer.

Yes mine was unlocked different method so it won't update normally.
That's why I asked if I could cross flash to TMO

if your phone is unlocked via whatever method, it wont interfere with system updates. OTAs will happen at regular intervals based on the firmware flashed on the phone and the recovery status. Stock recovery means that youll get OTAs, if youre not, its likely a glitch and has nothing to do with the unlock status.
If youre looking to get your phone working on tmob and its a spr phone, all you really need to do is unlock it, put the new sim in it and configure the APN. If you want full features like voLTE and wifi calling, then youll need to flash a tmob firmware version on your phone which requires the patched version of Odin. I have a Cricket branded (originally, at least) S9 and i flashed the U1 firmware on it via patched Odin and the phone now thinks its a factory unlocked S9, as i also unlocked it via "alternative methods". Perfectly seamless transition and i get OTAs all the time

1. is there a way i can swap for another career rom
2. can i flash international rom just throug odin so that i dont deal with verizon bloatware.

Yes you can switch the firmware on the sm-t867v from Verizon to TMobile or Sprint. It keeps the bootloader locked down so root is still impossible but since you are not looking to root it just switching the firmware version should work just fine. I personally have metro pcs and their $15 unlimited tablet data plan on mine and I switched my firmware to TMobile so I could pick up the LTE bands it would not connect to with the Verizon firmware. All you need to do is download the modified Odin 3.14 and the firmware of the carrier you wish to switch to. It HAS to have the same base model. For example I went from the SM-T867V firmware and flashed the SM-T867U firmware to the device. So your firmware choice absolutely MUST have the SM-T867 in the beginning of it. Any other firmware will most likely brick your device if Odin even allows it to flash. The thing that makes the difference between Verizon and TMobile is the user userdata file. You must flash it with the rest of the firmware files, So BL, AP, CP, CSC, and Userdata. Don't worry, the stock firmware will come with the userdata file. Also its best that you don't flash the CSC-Home file but flash the regular CSC file as the home one will not delete your data and its probably best to do a full wipe when switching firmwares, so make sure you back up anything you don't wish to lose. When the flashing is finished it will boot and instead of the white screen with big red circle for Verizon you will get a pink TMobile screen and it will be model SM-T867U now. All OTA updates will still work without problem and you will get a functional dial pad which works for all the secret menus and all that fun stuff. BTW, I take absolutely no responsibility if for some reason it messes up or bricks your tab s6 lte. Goodluck and enjoy your non Verizon tablet.

I'm glad it worked for you without any major issues. This was the first thread I've given any real instruction on. Hope your tab continues to work perfectly. I broke the screen on mine so the only thing it's really used for is an android PC. Thank God for the Tab S6`s ability to output video so easily and the Samsung DEX software.
