How get back your carrier services if you changed your CSC code
Well with the help of these great XDA members I was able to restore my carrier services to my ATT 986U branded phone.
I made the mistake of messing with the CSC code without doing enough research. The mistake I made was using the procedure below on my 986U when it was meant for 986U1.
(I just pulled my SIM, entered *#272*MY_IMEI# and changed CSC from ATT to XAA. Rebooted phone without SIM and checked for update.)
Doing this made my phone lose all of its carrier services and I could not revert back. Luckily with the help of the XDA members they provided a tutorial on how to restore the ATT carrier services. It has been confirmed to work on Verizon and maybe other carriers. Follow the instructions below provided by @mlr_90.
1. First Flash your device with the U1 firmware found here using the patched Odin3_v3.13.3b: https://forum.xda-developers.com/galaxy-note-20-ultra/how-to/ota-ota-firmware-n986u-t4143833
2. Second make sure you flashe the AP,BP,CP and CSC found in the file. (Not the HOME_CSC)
3. Make sure to remove your sim card when you flash rom. Reinsert the sim card once phone is booted up and done with the initial setup. Once setup is done pop in your carrier sim card and you should get a message stating to reboot your phone. This will change your CSC code back to ATT/ATT/ATT from XAA/XAA/ATT.
4. Once your phone reboots confirm in the software information that your CSC is back to ATT/ATT/ATT
5. Now you can flash back to the U version firmware. Currenlty the latest is ATI6 found here https://forum.xda-developers.com/galaxy-note-20-ultra/how-to/ota-ota-firmware-n986u-t4143833
6. Flash using the U firmware using the instrucitons in step 2, but this time make sure your flash the HOME_CSC instead of the regular CSC.
7. Once this is completed flashing you should see your carrier logo during bootup and all the carrier services will be back on your phone.

Ouch. That sounds painful...
Very very good tutorial my friend. I'm sure many will find this very helpful. Thanks for taking the time to write this up.[emoji106]

In using the U1 firmware on my Verizon note, I gained access to the security section in device care and also called ID and spam in phone. When you flashed back to ATI5 U firmware, do those get removed again? Really the only thing that I can see I am currently missing is Carrier Video Calling, but was just planning on using Duo.

I had those features prior to going back to U. And after returning from U1, those features are gone unfortunately.
I have an unlocked Note 20 Ultra. My CSC info showed as TMB/TMB/XAA.

Doesn't it feel good Borijess that you were able to help, believe me when i say this there are going to be plenty people who will get help from this but plenty people are selfish and entitled they would never hit thanks nor acknowledge nevertheless you did good by posting this (you could have ignored the suggestion) now may i suggest one more thing - Edit the title to be more Generic like "How get back your carrier services if you changed your CSC code"
While in the main description you can write you did this for ATT and we have confirmation that this works for Verizon too. So more people would be able to use it. Going by the forum posts believe me this is an issue many are facing.

Power off phone. Then press the volume up/down plus power button at the same time. All three buttons pressed same time will get you into download mode.

Same procedure instead you need to use the FW for Note20 SM-N981U:
Flash to U1 FW N981U1UEU1ATH3.
Then flash back to U FW N981USQU1ATH3.

Does phone status still appear as "official" or "custom" after updating to 7.0? I have to use Good Work for work email and it will not install if the device shows "custom" status. Thx.

Would the method of getting the Verizon firmware, then rooting it and installing flashfire, then flashing the S7Nupdate work?
Can anyone confirm that there are no major bugs like data from carrier not working or calls dropping or anything like that

I wanna give this a shot but flashing Verizon FW scares me. If you don't mind me asking, did you follow the procedure in the OP to the letter or did you alter the process?
Also, are you able to surf the net (or multitask at all, i should say) while you're on a phone call? I think I remember reading about this limitation with Verizon FW a while back. Thanks in advance

Hello all,
I have a question regarding the base firmware I have found that is All_OYN_G950USQU1AQC8 multi cert tar.md5 . This firmware seems to be the base stock factory firmware and one user has tried to install it on the Sprint variant of G950U along with the PIT file and repartition. What seems to have happened is that we seemed to have returned to stock Sprint firmware. However, does anyone know why Sprint bootanimation and such will remain? Is this an issue with the firmware package (4.4GB and seems to have all G950U carriers within the file) or is this an issue with the ODIN software for this phone? Also, I know Sprint is a pain to deal with bc they seem to Carrier SIM lock once their SIM card is inserted. Maybe someone could shed some light on this process for us. I personally don't have another SIM to try. I will post the links to both the thread and firmware and pit files below in post 2. Also, found an interesting firmware that claims to have the eng bootloader but can't get it from the site as I am not able to purchase via yuan.
Thanks for anyones and everyone's help.

I believe the issue is we need the newer Odin with the userdata slot. That is where the boot animation and carrier specific items are.

Nice! The test devices allow switching carriers just by changing the SIM. Maybe we can find a way to get the retail devices to do that.

Hey guys the device we are testing is mine. Also thinking it might be the odin. The funny thing is that I flashed that firmware and everything from sprint (meaning apps etc.) its not there except of course for the splash screen and locked to the carrier. Im still waiting on the ODIN because I bought a Sprint Galaxy S8 thinking it was unlocked and NOPE!!!

I did a wipe in the recovery before booting. Wouldn't that be the same as a factory reset? At work now but will try that as soon as I get home. I'll report back with the results. Thanks.

Factory reset was a no go. Flashed back to latest unlocked f/w and everything is good for now. I flashed the csc file for verizon in odin by itself. Pretty sure thats were i went wrong. Is there a special procedure to flash back to stock from unlocked?

I noticed that every time I flashed back and forth, remnants of Sprint stayed until I performed the carrier switching part of my guide...at which point I was able to put complete T-Mobile...For you, maybe that may help going from unlocked to VZW.

You may have to call your carrier for a new SIM...or have them reprovision it and say that you are having data issues...it may have been a provisioning issue all along...

Sim works fine in my my backup Note 5. Also works fine in my Note 8 on unlocked fw. Its just when I return to stock it does not register on any network. Seems to have something to do with my csc files. Using the Samsung device info app it says there are no available csc's and my build version is listed as XAA instead of VZW like when it was original stock. Maybe you could do a step by step guide for return to stock. I must be missing a step somewhere. Thanks for the help btw.

Actually carrier flashing is the step by step guide...there may be a problem with your device or your download....but other than that if your device works on unlocked firmware and not carrier firmware, I'd say bad download...because following carrier flash guide gets you to carrier firmware...

The no connection issues I was having were the result of the incorrect carrier csc files not being loaded. I've been playing around with various csc features and have just about found the perfect combo.

Great guide but you should mention from where you got AT&T firmware for note 8. This firmware is not that easy to get.

It says still updating...but will do...I'm just not finished yet...that's why is says at the bottom to pm me and still adding thanks tomorrow...and samfirm will download the ATT files...also I did not host the ATT firmware as it is still directing to your link...if I host files I find them myself...you can also purchase a subscription to other VIP hosting sites and download the ATT firmware...I just haven't bit the bullet...and I have pointed several people to your same link....in various posts...in no way did I take credit for it...not to mention that you yourself have no mention of where you got it, unless you developed it yourself...lol....I will be hosting AT&T firmware that I get myself though...thanks for the pm...I appreciate it... I'll be sure to give you credit as "and others" in the guide...
Please if anyone feels that they should be mentioned...pm me...it takes a while to create a thread that is semi-professional and not just a single link...and I may leave things out unintentionally...a pm will allow for edits quietly and professionally...please enjoy and I do not require credit because all we are doing is sharing and contributing for the sake of enjoying our Note...

So has the experience been better using this rom over stock? Any improvement on battery life? Performance?
So I have a unlocked carrier Note 8. I flashed the AT&T firmware and still do not get Wi-Fi calling. VOLTE works but trying to setup Wi-Fi calling fails.

thanks man tried it this morning worked like a charm.
I been on the phone with AT&T trying to get my imei whitelisted. I told them it was an AT&T phone. Running stock AT&T software. If I am running this software all my updates coming from AT&T now?

Someone said to add fota to apn using shortcut master lite to get OTA from ATT if you don't get OTA updates normally...but yeah if all is stock and working cohesively you should get OTA from them. If you are on unlocked and you just flashed csc and USERDATA files you may still get from Samsung...you just got ATT to whitelist the imei...
Some of the unlocked updates have came from carriers...though (it's kind of odd I looked at where my SPR SM-N950U1 came from and it was the same server that the Sprint s8+ updates came from...then I went back to just XAA and checked for the XAA SM-N950U1 and it was a Samsung server...so you may be getting ATT no matter what once your imei is rightfully registered...
All firmwares for SM-N950U and SM-N950U1 are located at link in OP....for those looking for Firmware

Not sure, I haven't looked....
My zips include BL, AP, CP, CSC, HOME_CSC, and USERDATA...
This one is ATT...
It is compressed individually...and includes a note to use new Odin
So I just flashed the latest att firmware on my Verizon note 8 and just trying to get volte and wifi calling to work but no luck. I've read the combanation file is need to "carrier switch" but none of the combanation files seem like they go with the latest pie firmware? And help and or pointing in the right direction would be greatly appreciated
My Note 8 was purchased from ATT, then I unlocked it using a service, then I switched to T Mobile years later. When I switched to T Mobile, the firmware updated itself to T Mobile after I booted with a T Mobile SIM.
Now, I am trying to flash it to U1_XAA so that I can gift it to someone in China. However, after factory resets, even from the recovery menu, it fails almost immediately during flashing. Would you please guide me on how to get this flashed to U1_XAA? Or is it ok just to leave it the way it is (U_TMB) and send it out?
Thank you!
P.S. this is with Android Pie, since I got the update while I was still on ATT. I tried flashing with the patched Odin as well, same thing...
Well I just got my FedEx box open. Downloaded the latest ATH4 U firmware using Samfirm
After I had already set my Samsung unlocked device up on the latest U1 ATH3 , I just booted into download and flashed only the Home CSC of the U firmware ..... wifi calling and volte!!! No problems
Lol...could you please pass this on. I tell peeps all the time and they don't believe me..lol

How exactly did you get into download mode? Every option that I have tried only gets me to a screen that reminds me of a Pixel bootloader.

Were you also using an old ATT SIM card as well? Are you now ATT/ATT/XAA?
This sounds SO easy! Didn't wipe your phone either after flashing.
Thanks!!!

Yes ATT/ATT/XAA
And yes, took my old sim card out of my old phone
I know this is about AT&T but I'm curious as to why you had to flash a whole firmware. I just slapped a sprint sim in my unlocked and everything is working ... edit nevermind just the home CSC ... been a long day
i just flashed the N986U1UEU1ATH3 into my att note 20 ultra. got ride of all the att preinstalled apps.
Out if the box I flashed my U1 with the SM-N986U ATH4 firmware (including original CSC, not Home_csc) with the CSC country variant since I'm in AT&T.
I booted the phone with the AT&T sim inserted, my old phone offline. However, after going through the setup I still do not have WiFi calling which is very important. I have tried flashing the Home_CSC of the CSC country code variants for the SM-N986U but have been unsuccessful in lighting up the specific AT&T features.
Anything I'm missing?
I still can't believe how well this worked!
I did the OTA for the August Security Patch (U1 ATH3) pretty much after I opened the phone. I already has my old AT&T SIM card in the phone, then I used Frija to download the T-Mobile U ATH3 firmware for a locked device.
I flashed only the Home_CSC file (as jcrompton instructed) and now, I not only got WiFi Calling back, I also have AT&T Visual Voicemail, Video Calling, HD Voice.
I thought that I'd have to wait for someone to upload the ATT User_Data file and once again be stuck with all of the AT&T bloatware.
If this process has been working for a long time then I sure have been wasting my time!
Thanks again!

I was on U1 ATH3, flashed to USA/CSC SM-N986U ATH4 (with original CSC file) with no luck. Flashed only the home_CSC for the build, no luck, then tried the home_CSC for the TMO ATH3 all with no luck.
I turned Wifi off and left my AT&T SIM in the entire time. Any suggestions? I really need to get wifi calling going.
My device is AT&T locked but has anyone confirmed they are provisioned correctly for 5G and getting confirmation on the SIM ? I changed my plan to Unlimited Elite and used the SIM that came with my device, but under Settings/About Phone/Status/SIM card status/Mobile data network type it displays LTE. I had a chat with Tier2 earlier today which they couldn't resolve.

Probably a dumb question but why buy it unlocked to flash the ATT firmware rather than buying is straight from ATT?

Not a fun question at all ..... but I get incentives usually when buying from Samsung. I like to buy unlocked
But actually I never " flash ATT firmware" ..... this thread was to confirm that you can keep the unlocked U1 firmware., flash only the carrier U Home CSC file, and thus maintain all the benefits of U1 unlocked firmware but still have the carrier calling features without the bloatware on carrier U firmware.
Edit
In addition. Anytime I've had a carrier device I always flash the U1 firmware with the U CSC so the end result is the same even if I have a carrier device

Something is defintely not right
Try using the patched Odin and flash all the U1 files except for put the U full CSC in (instead of the U1 csc) It'll wipe your phone but i know for sure that'll work. I've done it 100 times with various phones
I can't find the Att U file for the Note 20 Ultra, where would I go to find that? I want to flash the carrier software features to my unlocked note.

If you were to travel overseas, you can use the unlocked phone with overseas SIM which is cheaper than paying for ATT's international pricing.
