[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?

 

[Hopeless313]

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

 

[bradley_az]

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

So, I need to root to flash this, right?

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

Does this unlock your phone?

 

[Vish.N]

Nope. Just the firmware change. SIM will still be locked. You'll need a unlock code or carrier to unlock it

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

 

[yedidi2006]

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

 

[Belswick1995]

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

 

[dinggus]

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)
