I flashed the U firmware and then flashed the latest Tmobile, or at least it think its the latest (Baseband: G935TUVU4APIA), and all functions seem to be working properly, tested SMS, MMS, WIFI Calling, not too sure what other Tmobile functions also are related to the modem so let me know what else I should test.

Is att your carrier? If so is volte working for you? I loved the u firmware but lack of volte bothered me.
Volte seemed to have worked fine. Anytime I was on a call 4g LTE was workibg. No HD calling or WiFi calling.

ATT is not my carrier, I carrier unlocked the phone and have only used the phone with a Tmobile SIM. I flashed the U firmware and the Tmobile modem firmware on it and I have seen better reception then when I had the ATT firmware installed opposed to the U firmware with the Tmobile Modem. VOLTE is not stated on the signal but the quality is the same as VoLTE of course there would need to be testing done on my end to prove if it is indeed working as VoLTE. Any suggestions? Would love to contribute with this.
EDIT: Unless of course you were asking if VoLTE was working with ATT on the ufirmware and if this is just ATT specific and if it is the case then my post wouldn't have much addition to the thread.

this odin writes to userdata? So it allows full carrier switch? That's huge if true
so how does this work when its time to get an ota update? do you need to flash back to att and then flash to the unlocked equivalent or can you just take unlocked ota's to update the phone?

You do not have to ODIN back. It will update normally. It was pulled from a US Cellular Device which was sold unlocked. I have the Canada version also with the built in Caller ID to identify unknown numbers with the Samsung Smart Call feature. and you do not have to program the APN. Yall let me know if you want me to upload it along with instructions.

I have a Sprint S8+
Have tried flashing over it with this ROM and a Verizon ROM.
Both flash worked completely n ODIN but when the phone reboots, it is still Sprint.
I have seen other posts with same problem.
Am I doing something wrong?
I have tried both Home CSC and Non-Home CSC and the Userdata file was in UMS field in ODIN.

I have the Verizon variant and downloaded the Canadian version, and flashed that over completely the regular CSC, not the home_CSC. This was using the prince comsey or whatever version of Odin, and I let it reboot after. During the setup I did the same thing the other guy mentioned where you only set a pin, and select yes to boot the device with your pin. Once I got through the setup I turned on dev mode, and flashed my stock FW, which was Verizon. I selected all files and chose the home_csc from the Verizon package along with the VZW AP, BL and CP files.
Flashed them all over and let the device reboot. Once it turned on it took a minute or so to get LTE and service in general but it worked.

Thanks so much for this! Just for clarification the Unlocked US Cellular version does not have Smart Call only the Canadian version does or am I reading it wrong? Just trying to figure out the difference and which one would be best for my G955U.

The Canadian one is the one with Smart Call
So this makes an att phone unlocked to any carrier?

Same thing happened to me. Successfully flashed but when it boots it still is an AT&T. I have the AT&T version and tried the home csc. Everything passes but it doesn't work for me. Weird
I'm on AT&T and wondering which one is better to flash. Is the only difference between us unlocked and canada firmwares the smart call feature?

Just an update but I tried the Canadian one on my device using the home.csc. Notice it does not have a UMS. It worked! The Canadian version is super clean! I am on AT&T, besides for the known things like wifi calling. Are we missing anything by not using the US Cellular version?
Thanks again, it just seems like the US cellular version wouldn't take for me but I am now happy and bloatware free.

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...
Using Odin 3.12 and latest 930T firmware
I can flash older stock firmware which makes me think it's not the bootloader?? I've done this exact conversion a couple times in the past on other phones without any problems at all.
Error Message Fused 5 Binary 4 .
Phone is officially unlocked and will allow calls with the T-Mobile sim, but won't allow LTE/ Data due to the bands being locked.
I successfully flashed 930T Modem (CP), but it didn't change anything

Your second post, but at least wait a day... And this has been covered numerous times.
Your binary 5 issue means that you can only odin current firmware for the sprint version.
You may be able to odin the latest sprint firmware, install the u modem, and that may unlock your bands.
But basically, you are stuck with sprint firmware until the others catch up

Check the last 5 digits of the firmware. It should have a 4 or 5. Your error message states that it has the newer bootloader.
On the train now, but you could go back between binary 2 and 4 with a pit file. Search this forum or the sprint s7 edge one.

My 930T modem on the phone (the one I flashed) starts with a 4... build number on the phone is 930P and last 5 starts with a 5... again I really appreciate it! I'd read there was no way to know which bootloader was installed via a code on the phone. I hadn't found any info on bootloader release dates so I was working backwards installing firmware

My phone is on the U firmware, but I remember using this method about a year ago. You can try to ODIN the PE1 firmware with the PIT file. It let you go from b4 to b2, not sure if it will work for b5 to b2...in theory it should, but you who knows. The most important part is adding that pit file.
So you install PE1, then you can install the U firmware
Worst case scenario is that you probably just have to reinstall the firmware you have now.
Please let me know if this ends up working.
Flashed newest 930P firmware and switched out with newest 930U modem... bands still locked. Everything uploaded smooth through Odin, just no change in service... messed around with VPN settings a bit and tried a 4g app.. still no data. Haven't tried a pit file yet

Tried it both ways with and without.
I'll try to mess around with the bands tonight via your link. I appreciate it... prior to this bootloader even the bands weren't an issue for me... I've spent way more time on this phone than it's worth lol. The old man I bought it from spent over $800 leasing this thing. Frustrating that Sprint thinks they can stop him from switching carriers now that the phone is his.
Had some time... I enabled band 17 (it wasn't before).... still no LTE. I've gotta find which bands are needed in my area I guess. I have access to all of them via the thread tutorial you posted. ... feels like I'm almost there!
I don't think it's the bands that are the issue. All the bands I need are checked/unlocked already. From reading I don't get the impression that there is a best "in my area" band. ALL the LTE bands listed on T Mobile's site were already unlocked in the phone. ??

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.

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.

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

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.
At&t does not post the U firmware only the unlocked

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.

If someone's ATT phone was corrupted, how to restore it without the ATT firmware?
