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.

Verizon is sim unlocked you can just put your sim in and go. If you want to get all the benefits of tmobile simple flash the latest tmobile firmware with odin then internet calling video calling and all that will work. Goto the tmobile thread to find the latest firmware.

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.

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.

I got a S7 edge US Cellular branded from Walmart.. It is UNLOCKED. I put in my tmobile sim, I get lte, but, signal strength is low.
Is it possible to flash Tmobile software on this phone? The reason is I am not getting any strong signals (inspite of it supporting all corresponding LTE bands from Tmobile). Has anyone tried?
what options do I have? Any help is appreciated.
Thanks!

US cellular is just G935U I believe. You can just download the tmobile firmware, stick it in Oden and press flash. I suggest you to try flashing only the modem from the T firmware and use 935U firmware for everything else.

Is your US Cellular G935U? I bought a used one/unlocked -not in Walmart though- and it shows G935R4. I guess I will brick my device if I flash the Tmobile firmware. The problem that I have it show 4glte and speeds are amazing, however there are no bars shown. When I get a call, it shows bars and makes the calls with no issues. SMS works great.

Hello,
I had a s8+ and I was able to re-brand it from AT&T to T-mobile; although I don't remember the exact process. I recently got an S10+ Verizon from my boss and I have it carrier unlocked and running on T-mobile. I was wondering if you can flash T-Mobile branded firmware so I can get access to WiFi Calling and the built in visual voicemail. Any help would be appreciated.
Thanks

Thank you. Do you know if the hardware is the same for the verizon and tmobile phones? with it just unlocked and with the tmobile chip the signal wasn't as high. I'm hoping when I flash it with t-mobile firmware it flashes the radios to use the tmobile bands as well.

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.

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.
