**** The Official Samsung Galaxy S7/Edge Thread ****

For those on a BTU phone (or BTU rom) and on the Three network wanting Wifi calling etc, I've made some edits to the CSC to enable it without having to flash a bloated Three (H3G) rom or CSC: https://dl.dropboxusercontent.com/u/8686251/csc.zip
You'll need root I'm afraid. Copy the contents of the zip to / (root) and overwrite then restart.

Wifi calling, VOLTE, HD voice etc etc all working.
Additionally, features such as unidentified caller ID, call recording etc are unhidden and can be turned on or off.

How do you do this? Wouldn't mind trying for Vodafone.

I downloaded a nougat H3G rom, extracted the CSC and compared contents against the BTU CSC from my phone then merged in the networks list (specifically the IMS bits in customer.xml I'm most interested in) & settings and the key files from /etc, though not 100% sure if these keystring files are needed.

I've just done the same for Vodafone if you'd like to try it: https://dl.dropboxusercontent.com/u/8686251/csc-vod-btu.zip It isn't a flashable zip, just extract to root directory.
Back up customer.xml and others.xml from /system/csc first so that you can roll back without reflashing CSC if you wish.

So I tried to root to use this on my unlocked S7 Edge on Three running Nougat BTU firmware. Not sure what I did but managed to brick the phone. Couldn't get past the Samsung logo on start up. After lots of messing around managed to reinstall the Three Nougat firmware (thought I'd try it over the BTU). All working fine now.

So thanks to L33 for posting the custom CSC but a couple of points for anyone considering this. Be very careful about rooting on Nougat (I think the AP file I was using was the problem) and also, IMHO the Three firmware is absolutely fine. The small amount of carrier bloatware that exists can all be uninstalled.
 
It seems that Vodafone contract customers are getting the OTA update as of right now. Mine has appeared after checking manually (it wasn't available earlier today) and others reporting the same on the Vodafone forum too.

It sounds like you may have missed a step, when rooting on nougat (or even marshmallow on the S7) you have to disable dm-verity and forced encryption. This is usually in the form of a flashable zip kernel patch (no-verity-opt-encrypt.zip) and then a reformat of /data is needed.
I agree, the Three rom is about the best of the UK carrier branded roms for lack of bloat.
FWIW the csc 'mod' should never cause a soft-brick; the phone will happily boot even without a CSC you'll just be missing carrier network settings etc.

Great, thanks for the info, will remember that if I attempt it again in the future.

I haven't had to do anything special on mine on vodafone on btu firmware, just disabled wifi calling in my account then renabled it by sending the text to Vodafone, waited almost 24 hours to get a text back saying wifi calling was enabled, restarted phone and all working good.

Well that's certainly easier. My Google-Fu is failing me, do you remember what text you sent?
 
I completed my OTA update yesterday to Nougat. Now Gmail isn't working and Play Store doesn't open either. I've tried lots of things but not a factory reset, hoping to avoid that, anyone got any ideas what else I can try before the reset?
