Question to Dev or rom flashers on this phone - Samsung Galaxy Note 20 Ultra Questions & Answers

Hello,
I have a N986U1 model unlocked and use it on T-mobile and was wondering how to change it to Thailand or a CSC that has call recording. Can I flash another model CSC to get the thailand or another call recording csc?
Thanks.

You can't unfortunately since US versions can only use US CSC

T-Mobile VoLTE

Did anyone ever figure out T-Mobile VoLTE on the Exynos S7?
I'd like to push this, as I'm missing the option in telephone app as well. I flashed latest stock firmware from sammobile for germany, t-mobile. This is my carrier and it definetly supports VoLTE. But I don't get the option shown in the app. Anything I could do about this?
Have you ever looked at mobile networks ?
Oh it is german csc? Did you set the CSC properly for germany? You will see the CSC setting thing in the development forum.

You need a Device that was branded by Telekom.
And you have to activate VoLTE via your Serviceportal :fingers-crossed:
Just go to kundencenter.telekom.de and choose Mobilfunk. Then go to Tarifoptionen/Telefonie and you can activate VoLTE and WiFi-Calling for free.
This won't work in USA

Am I the only one not having nougat?

I am late to join galaxy s7, just recently got one on eBay. UK Vodafone locked. I had it unlocked couple of days ago. Expecting it to receive nougat ota. But nothing has happened yet. When will I get that? I want to try out nougat then decide whether to root.
Removing the network lock won't have any affect on which firmware your phone has, only that you can now use it on any network & so as is you would be waiting for Vodafone to release a VOD version of Nougat.
AFAIK There is only a BTU/Samsung generic version of Nougat available in the UK on the S7 right now so if you wanted it sooner you could flash to BTU.

Thanks, Do I still need to root to flash the generic rom?
The update is available in India now! I have updated my S7 to Nougat VIA OTa

Root is never needed to flash ROMs

Just confirmed with someone from work that his unlocked (when bought) phone also hasn't got nougat ota update. Just wondering anyone here from uk who actually got the update?

Does flashing to a different rom, albeit a factory one, void warranty, trip knox or stop OTA updates? I recently bought a Galaxy S7 with Vodafone Spain (ATL) firmware (i don't live in Spain btw, I bought it from a store) and I'd like to flash the unlocked UK rom (BTU), so I can get Nougat, but i don't want to void my warranty.

Did they buy their phone from Carphone Warehouse? Only if so they're probably on XEU rather than BTU.

Yes, that is XEU. I read about the XEU firmware on a forum somewhere, he hasn't gotten the update yet. BTU is the unlocked UK firmware and the Nougat update for that is out.

Indeed that's XEU (as the previous poster said)
XEU & BTU seem to both be the same but they have different CSCs which would explain why you're not getting the update as it's not out for XEU yet.

Flashing a stock ROM eg from SamMobile won't trip Knox. Only customs ROMs & rooting do that. OTA updates should work fine if the right flashing procedure is followed.

Thanks a lot, I was getting frustrated because I don't want my firmware to have anything to do with any carrier. Do you happen to know if there is a chance that Samsung's service can see that the BTU CSC is not the phone's original CSC and decline a warranty claim?

When are we going to get it?! I'm from the UK with an unlocked S7 flat, bought from Carphone. And of course it's with XEU.

You could run into problems there if you needed to send the phone in for repair if the firmware is checked by the retailer or whoever they send their phones off for repair to. Personally would just flash it back to the original CSC before sending it off. Both CSCs would need to be on the same Android version though as from what I remember reading flashing an Android downgrade can brick your phone. I did read elsewhere someone managed to flash back to Marshmallow from Nougat as VoLTE wasn't working in Nougat as it turned out both were using the same boat loader but that's the only case like that I recall.
From experience Samsung's Smartswitch software doesn't look your phone up to establish which firmware it should have. It just goes on the current CSC if you were eg. to do an emergency firmware initialisation.

Flash the firmware from on SamMobile it's probably better than upgrading via OTA as well.

I'm on the same boat and am really upset that Samsung makes things harder
every year and this time around CSC is totally different now.
Please let me know if you find any good news.
Switch to the canadian model and you'll have everything but root, i'm sure theres plenty of people that will do a straight swap.

download the rogers firmware from sammobile and join batstock rom telegram support channel. The OP can help you out. All you have to do is upload a file from the download there and he'll add the csc to a flashable twrp zip that you can install to fully enable all rogers features.

I got bad news for you. VOLTE and Wifi calling only works on android phones that has been bought from Rogers. I have the unlocked version from Samsung.ca and it still didn't work.
Correction: The only unlocked phones that work on Rogers VOLTE and Wifi-Calling are the iPhones.

i see.
next thing you want to try, make sure your build.prop product name matches that of the rogers phone.
also, my carrier disables feature if it detects root such as wifi calling. if you have magisk hide and an app for wifi calling uou may want to try hiding those apps from root.

I already called Rogers tech and VOLTE and WIFI Calling don't work on Android phones that was not from Rogers. No matter what you do, its the IMEI number that triggers their system to enable it on their end.
Unfortunately all carriers including Bell, Telus, Fido, Virgin and Freedom Mobile do this.
if it trully is incompatible, it is more likely to do with the difference between th band availability between the international model and canadian model... a quick google search will allow you to compare band availvility between phones and what bands are used for the carrier.
i don't believe it though, that just makes it hardee for them to aquire clients with existing handsets.

How to add Sprint Call Plus on unlocked s8+?

I'm using an unlocked s8+ on Sprint network. Everything works include Wi-Fi calling. But I didn't get any update for call plus like Sprint version did.
Is there any way to add call plus on unlocked s8+? Hope I don't have to flash Sprint firmware.

The only problem is I can't dial certain numbers, like #CHP or #NHP.

Yes and no. WiFi Calling and all of the bloat will be there and it will work as long as AT&T doesn't realize you are using a device you didn't purchase from them. Once they realize you didn't buy your device from them, they will disable your line from using WiFi Calling.

I'm not sure. I was never an AT&T customer.
After giving my girlfriend my S9 Plus and her fighting with AT&T over the WiFi Calling b/s, because they would keep disabling it on her after switching back to her S5 Active to get it re-enabled. I finally got her to switch over to T-Mobile.

I can't complain about the service I have had with T-Mobile. In Virginia, it is better than most other providers. Blacksburg now has band 71 deployment and Hampton has pretty good band 12 service. In upstate New York and Canada, I haven't had any complaints either. Going up and down the east coast earlier this year, I didn't have any complaints, even after traveling through West Virginia. Obviously, other areas may vary.
On AT&T though, my girlfriend had no service in her Hampton apartment, no service inside of NASA Langley, and no service at her parents home in Itmann, WV. However, on T-Mobile, she at least has good service at home and at work now, including inside of the buildings.
Well I flashed this ATT on my unlocked 650U1 and nothing ATT showed up, not even boot logo. It showed the correct model as G965U and version BRJ5. Loaded everything in odin. Any suggestions?
