[Guide] Enable Video Calling, HD Voice, & More - Unlocked Note 8 With T-Mo (Oreo / N)
There is a fairly simple way to enable T-Mobile features while using a N950U1 (unlocked) firmware while on T-Mobile.
*We are going to use two example firmwares from the latest Oreo release, N950U1UEU3CRC1 & N950USQU3CRC2., this can be done with older firmware just get firmware from around the same date.
1. Download both of the latest firmware for the N950U & N950U1.
2. Open Odin 3.13.1 and boot the phone into Download Mode
3. In Odin, Load the BL, AP, & CP from the N950U1 firmware (N950U1UEU3CRC1) but load the CSC from N950U (N950USQU3CRC2) (Do not use one labeled home)
3. Reboot, enjoy N950U1 with T-Mobile features and icons.

Will this retain or wipe data???

Odin wipes data.
Backup your data with your favorite backup/restore method/s before using Odin. So have the data to restore later with your favorite backup/restore method/s afterwards.

Nice. Going to try on my T-Mobile Note 8. Just to confirm what bloatware is installed by using the T-Mobile CSC file? I'm looking to get rid of all the T-Mobile bloat while still having the video call feature working

Will this trip knox?

I have no idea what is Odin and where do i get it?

Do some research. Watch some YouTube videos about rooting your phone. Then do some more research.

We are all here to help each other. That's what XDA is about

Nope. This is official Samsung firmware. No root needed and it won't break Knox.
I actually did this the other day but after flashing the U1 firmware on my T-Mobile Note 8 using the patched Odin I then used the regular Odin and just flashed the CP and Userdata from the T-Mobile U firmware and it enabled RCS, Video Calling, VoLTE, Wifi Calling and did not install any bloatware. Everything is perfect

Oh, ok, cool. I have unlocked and using on T Mobile, I have wifi calling and the like already. Since the new update, video calling was removed again. I don't even use it, but I still want the feature activated. I expected the unlocked version to have everything, not be missing features. Thanks

What happens when you install an update, does that mess anything up?

I have an sm-n950u with the crf3 update. Can I use this without harming anything?

Will this same method work if I have the unlocked Note 9 and I want to have AT&T features?? Do I just flash the CSC from the AT&T firmware and keep everything else the files from the U1 firmware?
I just flashed the U1 firmware on my Verizon note 9 to get the Verizon crap off of it because I have At&t but I realized that it isn't as perfect as I thought it was because I have no HD voice or Video Calling. Thank you!!

Only thing I dont like about this is that it does at the t mobile splash screen on boot up/shut down

What else gets unlocked? I already have WiFi calling.

I'm considering doing this "franken-flash" with the latest PrinceCosmy Odin on my 935U, but have the following questions (I know it's a 950U thread, but should be similar):
1. Will I still get OTA updates & are they safe? Has anyone tried a manual update?
2. If so, what should I expect; would BL & AP eventually flash to the T-Mobile variant or would each component (BL, AP, CP, CSC) follow it's own upgrade path?
3. Will it also fix the problem of T-Mobile forcing OTA updates to be done over WIFI? (happened the last 2 updates)
Here's the features I'm expecting to fix:
Flashing 935T CSC - Enable Video Calling, HD Voice, & RCS (pros), add T-Mobile bootup splash (big con)
--NOTE: VoLTE setting is available & turned on but doesn't appear to fully enable HD Voice; WifiCalling is already functional
Flashing 935T CP - Enable 4x4 MIMO & 256/64 QAM (huge pros), possibly lose roaming use of a few bands (2G CDMA: CDMA800, USPCS1900; 3G CDMA: BC0(800), BC1(1900), BC10(800); UMTS: B8(900); 4G FDD LTE: B13(700), B25(1900), B26(800), B29(700), B30(2300)) (con)
Flash any mixture - possibly break OTA updates (con); accidentally take an OTA update while mixed & brick phone (huge con)
I first called T-Mobile & asked if they could edit the IMS settings to enable Video calling. After elevation to tech support & some further discussion I was eventually told "it's not a T-Mobile phone so you're out of luck - call Samsung". Of course that'd be a waste of time since it's probably T-Mobile that locked out the IMS settings in the first place.
In case anyone needs them - I got the latest firmware direct from Samsung using SamFirm (pretty fast downloads). T-Mobile is the TMB "region"; that works fine with both SM-G935T and SM-G935U models & set to "auto" to get the latest.

in theory would this method work with the s8+? (with the s8+ firmwares, obviously)

The answer is NO you're asking firmware to replace/add hardware and that's not possible
I have a Verizon branded s7 edge and used Odin to load the 935U PI3 firmware. I am on T-Mo now and do have LTE band 12 working (validated with LTE Discovery). The research that I did found that the US variants have all the radios in them, but some carrier variants of firmware disable certain bands. By doing the 935U firmware, I also got rid of the notice on every reboot that I was using a non-Verizon SIM. So I now have all T-mo bands and no stupid SIM message.

I can vouch for same experience as SF-IT guy. I bought a G935V and flashed with G935U firmware via odin. Works on T-mobile, even wifi calling works. Currently on the latest PI3 version of G935U firmware. I would that you search the forum to see if you can flash the G935T firmware directly. The only downside of using G935U firmware is that the FM radio chip is not enabled in the firmware. I read that the all the carrier versions (September security patch and newer) of the G935 firmware have the FM radio chip enabled. I prefer the 935U version because it there is not carrier bloatware. Samsung bloatware is still there.

So what would the FM radio chip do? Just enable FM radios is all? Because if that's the downside then it's not a major setback as not too many people use the FM radio.
I don't think you can

You definitely can. All US versions of the S7 & S7 Edge are the same hardware and can be flashed to any other US firmware. (including the U firmware that automatically works on all 4 carriers)

So what you're saying is that flashing the U version firmware will unlock by default all 930"X" and 935"X" phones? As in it just unlocks the mofo and debloats some while you're at it?
What's the catch? It seems too easy

Bloat is definitely gone on the U firmware, which is great. My phone runs faster and has more free space too.
I think some carrier features aren't supported on the U firmware. On T-mobile everything works (VoLTE and Wi-Fi Calling), but I think AT&T might have some issues with those.
If the phone is SIM locked to a particular carrier, I'm not sure that automatically gets turned off or not when you switch to the U firmware. You might need to contact your carrier first to get an unlock code?

What if I got a temporary unlock from t-mobile unlock app and then flashed this firmware? Would it make it permanent? Seems quite possible, but I don't know if the temporary unlock actually unlocks the phone or just inserts a bypass that would disappear if flashed.

I unlocked my US TMo phone when stock, rooted, and am running Echoe - which has a glitch where WiFi calling sort of works (can receive calls but not make them). In the TMo forum, there are threads on U - your comments here are more specific to what I am interested.
Which U firmware are you on and are you rooted (is is updated to latest v4 bootloader version), and did you have to ODIN and full wipe with CSC or did you get by with CSC Home to preserve data?
Also, are you on U CP or did you flash TMo CP to get all the bands?.

EVR to BTU

Hi,
I'm looking at changing the firmware on my S7 EDGE from EVR to BTU.
How do I ensure I keep the data on my phone? Will OTA work properly on it when I flash the firmware?

You cannot update via OTA when changing to a different firmware unless it is EVR firmware. If you flash CSC then you can get OTA updates.
The only way to retain the EE Wifi calling is to remain on EVR firmware.
I thought the WiFi calling option worked on BTU but Volte did not?

I have BTU factory unlocked and unbranded device and I can confirm wifi calling works on EE. Just enable it in the settings.
I debranded mine from Virgin UK to BTU, I have no wifi calling options although it doesn't bother me as I don't use it anyway.

Which firmware are you running G935FXXU1BPLB??
When flashing from EVR to BTU, what items should be selected?
BL, AP, CP, CSC (or CSC home)? I'm not fussed about VoLTE as EE keep having outages, however I do need WiFi calling. I tried flashing Nougat last night and selected BL, AP, CP and CSC but WiFi calling option was gone from settings
Thank you

I have recently flashed the BTU Nougat firmware and can confirm that I am able to use WiFi calling on EE
Flash AP, CP, BL & CSC (or CSC_HOME if you want to retain data but may cause some issues)
Wonderful, thanks for confirming. I've downloaded BTU 7.0 and EVR 6.0.1 from sammobile so I guess my steps are:
1. Full backup of my S7 Edge (EVR 6.0.1) with Smart Switch
2. Remove SD card
3. Flash BTU with BL, AP, CP and CSC
4. Full reset/erase
5. Test WiFi calling, presume it's in the dialler settings still
6. Restore data/apps with Smart Switch
7. Check for any OS/App updates
8. Have a cider
Sound good?
BTW, when I last had a go at flashing BTU 7, there was no WiFi calling in the dialler settings Hopefully it'll work this time and at some point, EE will allow VoLTE (if IMS doesn't keep falling over).
Cheers
I can't find any WiFi calling options in settings on BTU 7 which I flashed over my EVR.
Interesting, that is why I'm reluctant to do it again. I've heard it work for some and others say flash with BTU 6.0.1 and then OTA to 7.0
Not that WiFi calling matters again now as EE have yet another IMS issue, no WiFi calling or VoLTE ....... AGAIN!

What is this IMS issue you're talking about?
Anyways, I've had VoLTE working since the Nougat ODIN files became available.
Flash official Nougat files + BETA 1 CSC (Nougat OXA) and Wi-Fi Calling and VoLTE works fine.
The IMS (IP Multimedia Subsystem) is the tech stack that allows for VoLTE and WiFi calling over 4G.
Regarding your method of retaining VoLTE/WiFi calling, I like it. Where can I download the beta firmware from in terms of a reputable site?
Incidentally, do you know which beta version stopped VoLTE on EE?

Want to Flash AT&T or Unlocked Firmware on T-Mobile Device - A Few Questions

So I've spent a few hours searching XDA to find the right resources on how to flash a different U.S. carrier's GS7 Edge firmware on the T-Mobile branded device. I found out that since all the internal hardware for all U.S. devices are identical, I'd be able to flash any one carrier's firmware on to any carrier's device, provided there are no inconsistencies with the bootloader versions of the firmwares.
The phone is intended for an extended family member and I am able to purchase a T-Mobile GS7 Edge for significantly cheaper than from any other carrier. Because it will be used on AT&T's network, I wanted to make sure I got everything right before I get started. I either want to flash the AT&T version which will allow it to be fully compatible on the network, or the Unlocked version. Apparently, the unlocked version is completely debloated since it's not associated with any carrier and provides better benchmarks, especially battery life, so I'm interested in that.
I've compiled the resources I need in the following:

http://updato.com/firmware-archive-select-model?q=SM-G935U&order=date&dir=desc&exact=1
etc.
One question I have is whether I am able to flash the Unlocked firmware at all. I don't currently have the device in hand so I can't check the baseband version, but my understanding is that the Unlocked version is currently on a lower bootloader version whereas it is v4 for AT&T or T.Mobile. This would mean I would be able unable to flash the Unlocked firmware if the device already has a higher version of the bootloader, right? Conversely, I would be able to do so if the T-Mobile bootloader was on the same version as the Unlocked version (e.g., if the device hasn't had an update to its bootloader).. The same issue would arise if I wanted to go back to a carrier firmware. Where can I find a list of T-Mobile firmwares and their bootloader versions so that I can check? Threads I've searched are saying I can't go to 935U from 935A/T because of mismatching bootloaders but others are saying I can go back to 935A/T on Nougat (same bootloader versions?) so clarification would be greatly appreciated.
Edit: Just discovered the bootloader version can be determined by looking at the 9th character in the baseband version. Pretty simple!
Another question I have is whether flashing the AT&T firmware will give me VoLTE, Wifi Calling, tethering, etc. on AT&T's network. I've established that if I flashed the Unlocked firmware, I'll lose these functions (unless I root the phone, but that's a no-go since I need Samsung Pay intact). Just wanted to make sure that I would retain these features if I flashed the AT&T firmware on the T-Mobile device. Also, would I receive all OTAs pushed from AT&T while I'm on their firmware, even though it was a T-Mobile device? Or would I have to manually update it somehow?
Many thanks in advance.
Yes you can flash the unlocked firmware, I do recommend flashing the at&t CP (radio) though for better signal.
For tmobile all we lose is video calling, we retain everything else. I can't answer your other questions since I have not used this phone from tmobile on at&t. I have used the at&t model on tmobile with U and had no issues.

^^^^^this man is correct. Also, is the device you want to flash Carrier unlocked? Even though youre flashing a different carriers firmware or even the U firmware I believe the IMEI still needs to be unlocked from the original carrier. Obviously just pop the at&t sim card in the t mobile phone to see if its unlocked. hope this helps.

flashing the at&t firmware will just be like having an original at&t s7 edge so yes. The Unlocked firmware will be lighter with no video calling(no carrier apps, no carrier boot animation, some of the quick toggles will be different) you will retain VOLTE HD calling, wifi calling(if at&t has that) and with the at&t you will have all the bloat (about 2-3 GB of used storage plus more a tad bit more use on ram usage) which will use more battery. remember like stated above, if you do decide to flash the U firmware, make sure you flash the latest At&t CP being you will have better coverage since youll be on the at&t network.

I was able to flash back to T mobile from the U, I never tried anything with a At&t variant or the at&t firmware
I am also interested. If I flash
1) Will the device status remain "Unmodified" - I use Good for Enterprise for work email and it won't function on rooted or modified devices
2) Will Android Pay Work?
3) Will I get Software updates directly?

I am also interested. If I flash
1) Will the device status remain "Unmodified" - I use Good for Enterprise for work email and it won't function on rooted or modified devices
2) Will Android Pay Work?
3) Will I get Software updates directly?

I Flashed an AT&T S7 Edge with T-Mobile firmware and:
1) Status remains unmodified
2) Android pay works (as well as Samsung pay)
3) I've already got 2 T-Mobile pushed firmware updates that installed without any issues.
Don't know if this helps, but I'd think it would be the same going from T-Mobile to AT&T.
I did also have to use a modified version of "ODIN" and flash a "PIT" file because T-Mobile has a different partition than AT&T.

Thanks! I am almost ready. Final checks
- I downloaded 935U firmware from here https://forum.xda-developers.com/tmobile-s7-edge/how-to/4-28-t-mobile-935-firmware-t3597866 (File is G935UUEU4BQD2_G935UOYM4BQD2_TMB.zip)
- I am planning to use ODIN 3.12.7
- Since I am on ATT Network I will use ATT Radio (CP File). I downloaded ATT firmware from here => https://forum.xda-developers.com/att-s7-edge/how-to/odin-files-to-s4bqc2-g935a-t3582874
I will use this CP => CP_G935AUCS4BQC2_CL10280464_QB12904088_REV02_user_low_ship_MULTI_CERT.tar
Am I doing everything right?
Should I just flash all U files (including Radio) and flash ATT Radio later?
Please advise
Hi team
I have the tmo ime version of the s7 edge, but flash the ATT firmware BQC2 and now I can not go back to tmobile firmware or the U firmware I got the following error in Odin:
Error device info
Who can help me,?I going to gift my s7 edge to my brother and he is on Tmobile network
Galaxy S7 active
I have a at&t Galaxy S7 active unlocked and i transfer my service to T-Mobile but I am not able to get updates can I flash T-Mobile firmware so I can have the T-Mobile interface and updates. What do I need to do to get the updates.
All US variants can flash the firmware interchangeably. Just download the corresponding firmware and flash everything(Except for the modem if you'd want to keep the original modem). You dont need anything special. If the default odin dont work, then try the comey "cracked" version.

Why is it that we use the CP for AT&T; however, use the Unlocked CP for TMobile? Are the radios the same for the unlocked and T-Mobile variants? Where would I get this information if I needed it in the future?
I have a GS7 edge locked to T-Mobile with the Device Unlock app. Will flashing G9350U firmware unlock my device and bypass the Device Unlock app or will I still need to use this app to unlock?
Radios are different. I flashed ATT Radio after I flashed U firmware. Though honestly I cannot tell the difference

you did the sae thing that I am currently doing. going from tmobile (I believe) to AT&T firmware. I am going from verison (which shouldn't matter) but when I did it the first time odin 3.12.7 gave me a message of success after only one "sector" of the whole thing went green. but the phone rebooted to an error message. did I do something wrong? help??

Sorry not an expert, but I read several times here to use Price COmsy ODIN and I use that one. Please try
OTA Update is not working after changing to U firmware.
I had stock T Mobile last firwmare installed, but I was sick of poor battery and lag
so installed this firmware https://forum.xda-developers.com/tmobile-s7-edge/how-to/6-8-t-mobile-935u-firmware-qe2-t3619151, full wipe.
Now I have worst battery performance. 12% draining overnight (6 hours) without touching the phone at all. It shows a new update but it fails when I OTA update. looks like the update it's being installed but fails at the end. Don't know what's wrong but totally hate battery.
Edit: Android pay is also not working..

What pit file did you flash? Did you flash the the pit file Odin pulls from your phone? Did you flash an att specific pit file?

I have a SM-G950U1 can I flash SM-G950W?

I am on Telus and bought a USA phone. I have flashed the updates using Odin and the HOME_CSC so that it could be carrier set to Telus.
However, it still does not get wifi calling and volte even though I've had the carrier enable it too. The CSC did enable HD voice though.
My question is whether I can flash the offical Telus firmware on my phone as the hardware looks to be the same.
I believe I will need the modded Odin but just wondering if anyone has had success with other models rom on their phones.

SM-G950U switch to Unlocked ROM?

I have a Sprint Galaxy s8, but I am no longer on Sprint.
Is it possible for me to flash the unlocked ROM, effectively making it SM-G950U1?
My current build nnumber: R16NW.G950USQU5CSA4
I'm hoping when it's available I can flash to the Pie version of G950U1.

Only if Sprint unlocked the device through uicc unlock. If you flash u1 on a locked it's still stuck to the original carrier. As for guides there are several guides in the general section for carrier switching

Yes it is. I just did it yesterday. I was on G950USQS5CSB1 and didn't get wifi calling or VoLTE on Mint Mobile but after flashing G950U1 I now have them.
Since you say you are no longer on Sprint I assume you just want the unbranded G950U1 firmware.
Using samfirm on your computer putin G950U1 as phone and XAA as CSC and search. You should get G950U1UES5CSB2. It is the latest and has the same bootloader as you. Download it.
Download and use the 3B modded version of Odin.
Back up your phone as it will be wiped.
study here how to use Odin..... there are many guides
Use the CSC file not Home_CSC.
Have the sim of your current carrier in the phone when you flash.

This is exactly what I'm doing. Switched to Mint, but don't heav Wifi or VoLTE. Glad to hear that G950U1 works with both those (was worried I would have to flash TMO to get it).
Thanks again!
