EE Wifi calling

I have the BTU 'G920FXXU1AOD9_G920FOXA1AOD9_G920FXXU1AOD9_HOME.tar.md5' and when I try to flash the EE firmware 'G920FXXU1AOCY_G920FEVR1AOC1_G920FXXU1AOCW_HOME.tar.md5' it FAILS! using Odin. - Any ideas on how to solve this to get Wifi calling working?

Glad i found this thread...thought i was going to have to flash EE software...i got on live chat to them and they asked if i purchased direct to which i said yes (i didnt) and they just activated it there and then haha...so just lie to them it seems they do not check anyway
[Galaxy S6 Edge Q&A, Help & Troubleshooting] rgray99c:
Google "CSC Change galaxy s6" one of the options is "Enable wifi calling" problem is it doesnt appear to work, and by that i mean ive tried it, got a message saying something along the lines of 'youve activated wifi calling, youll receive a text in 24 hrs to notify you when we've enabled it' never received the text and it doesnt appear to be working (No status bar icon) so yeah you can do it without flashing (Root required) but afaik it doesnt work.

anyone know of a way to force a wifi call? i get a signal at home but its poor..so id like to force a wifi call when im at home and not use the mobile network

I assume, like me, you don't have the settings in the phone settings page to tell it to prefer wifi?

In that case the only way I can think is to turn on airplane mode and then turn wifi back on.
[Galaxy S6 Edge Q&A, Help & Troubleshooting] FSOP:
Afaik it'll use wifi over cell calls by default if you're connected to a compatible hotspot

I'm sure there's more to it than that, enabling a check box will not work if the necessary files and apps are not present. Can you confirm that you actually managed to make a wifi call successfully, please?

Hi, noob here looking for a bit of advice from the crafty folk that got this working.

I have followed all the steps, Rooted the phone and then changed the CSC, I assumed I would have made a mistake and it would brick my phone but to my surprise it seems to have worked.

I now have the option to turn on WiFi calling, but so far i'm pretty sure my phone is not using the WiFi calling feature, I notice on the EE website that it says it can take 24 hours to be activated ?

Did any of you's have to wait 24 hours for activation and will EE not be able to tell that I didn't buy from them and prevent it from activating?

I noticed that there is a new icon(see photo) supposed to appear in the notification bar when Wifi calling is on, has that appeared on your phones, coz it aint on mine yet(but I only did it a hour ago so I might have another 23 to wait)

Cheers

I'm gonna give them a phone and give that a try, my worry is that I already phoned them before I read this thread and tried to get them to set it up, so they may have noted in my file that I bought it online....

Unfortunately when I phoned up they already knew I bought it elsewhere, but she still tried to set it up for me, but so far it doesn't seem to have worked.

She offered to send me a free signal box instead, so hopefully that will solve my signal problems, anyone got one? they any good?
[Galaxy S6 Edge Q&A, Help & Troubleshooting] adrenalize_:
Yep I've got the Cisco one (which should be what you get) and it's great. WiFi-calling seemed to start and stop when I tried it, guess it might be the S5 as you sometimes see it saying connected to blah... Wifi when unlocking the screen even though wifi is set to never sleep!

The only problem I very occasionally get is voice cutting in and out, guess it's EE's IMS being congested as my broadband doesn't usually get congested.

Bonus is Virgin BT and any MVNO using EE also work.

Wifi calling however should give HD voice and call connection times are very fast, so I might try it again sometime.

If when you register the box it flashes green call them again, took 3 attempts which reading between the lines was staff not configuring properly and nothing technical!

Getting off topic so I'll shut up!
[Galaxy S6 Edge Q&A, Help & Troubleshooting] sjbx:
I'd never even heard about these boxes, wish I had known sooner, had a terrible signal for 8 bloody years in my house.

Cheers:good:
[Galaxy S6 Edge Q&A, Help & Troubleshooting] gadgetgaz:
Actually, no-one in this thread has confirmed that they have successfully made a wifi call by doing this mod.

From what I can see the only thing that has been made possible is to enable a setting in a user interface.

What is needed is for someone to compare an ee rom with a non-ee rom to find all of the additional files and apps.

Unfortunate but true.
[Galaxy S6 Edge Q&A, Help & Troubleshooting] sjbx:
Well I can officially confirm that it 100% worked for me, it happened mid call, the call cut out a split second and then it came back, I wouldn't have even noticed but I got put on hold and I noticed a little phone logo with a wifi signal coming out it.

I'm getting a signal box tomorrow so I shouldn't need it but I'm glad to know it works now.

thanks for the help whoever came up with this fix.

I'm on BTU firmware on EE, my phone was NOT bought through EE

I used CSC master to set WiFi calling to true. Rebooted

In applications> phone I ticked WiFi calling

I didn't get any message from EE.

When I text 'WiFi calling' to 150 I just get a reply saying to look at a website for Info.

Can the users who have it working on unbranded firmware please say the exact steps they used ?

I have a feeling even with CSC changed, they may only allow it on phones bought through them by checking IMEI?
[Galaxy S6 Edge Q&A, Help & Troubleshooting] sjbx:
It took a day or so before it started working for me, I phoned up to complain about my signal and asked them to set it up on EE's side and they did, so it's hard say if it would have worked without that call.

My Signal Box has solved my issues anyway, perfect signal for every room in my house.
[Galaxy S6 Edge Q&A, Help & Troubleshooting] adrenalize_:
I got mine activated by flashing the EE firmware (on an S5) and ticking the WiFi calling box. An hour or so later got the text saying it was activated. It was definitely not an original EE supplied handset though. I have it on the back of my mind that they might only do it on contracts and not PAYG though. I have flashed back since though as I've got a signal box as found WiFi calling too unreliable.
[Galaxy S6 Edge Q&A, Help & Troubleshooting] jgph:
That is exactly what I would like to do (flash EVR on to an S6 BTU) but can't because of the partition.

Anyone found a way to easily get EVR on an S6 BTU?

Thanks
[Galaxy S6 Edge Q&A, Help & Troubleshooting] f1ux:
Partition? I can't flash the EVR firmware because my phone is already on 5.1.1 and you can't downgrade. ( there isn't a 5.1.1 EVR firmware yet)

I've just called EE to get wifi calling activated. They didn't ask me anything about my phone at all!

The girl said she had to turn on the 'wifi sock', I then got a text and she said it will usually activate in. 24hours.

Will wait and see
[Galaxy S6 Edge Q&A, Help & Troubleshooting] rfangster:
Also followed instructions on this thread, called EE to enable it. It's been 12 hours and still hasn't activated yet.
[Galaxy S6 Edge Q&A, Help & Troubleshooting] f1ux:
Nothing here either.

I suspect the only way to properly enable it is with the EVR (5.1.1 still not out) maybe after that you can flash BTU back ?
[Galaxy S6 Edge Q&A, Help & Troubleshooting] FSOP:
Nevermind
[Galaxy S6 Edge Q&A, Help & Troubleshooting] FSOP:
It'll never work if you don't have the EVR CSC / enabled in the others.xml unless you've somehow rooted on 5.1.1 to change these settings :)

Did you get the text saying you were setup for wi-fi calling? If not, PM me your EE number and I'll see if I can get it checked / added to your account
[Galaxy S6 Edge Q&A, Help & Troubleshooting] f1ux:
I rooted and changed CSC. I still haven't had a text!
[Galaxy S6 Edge Q&A, Help & Troubleshooting] rfangster:
Trying to flash the EVR firmware - seems like the partitions on the unlocked devices are different to the EE devices, hence flashing fails. Would anyone possibly be able to give their EE S6 Edge serial number? That way it is possible to force KIES to flash the firmware onto the device.
[Galaxy S6 Edge Q&A, Help & Troubleshooting] FSOP:
Pop into an EE store and grab it from the about screen ;)
[Galaxy S6 Edge Q&A, Help & Troubleshooting] rfangster:
It seems like EE are using a different model for their in-store demos with model number SM-G295X. Phone app doesn't have WiFi calling, nor does it seem to have the EE CSC (No NFC logo when on) :confused:

EDIT: SM-G925X, not SM-G295X. Further research shows that the X model would be the display model - no mobile connectivity.

You managed to flash the EE firmware? Did you use the repartition option in ODIN?
[Galaxy S6 Edge Q&A, Help & Troubleshooting] slickric21:
Guys, just dropping in here, although I have an S5 900F - this is the only thread on here talking about specifically about this issue.

Ive been in the same boat as many others in this thread, I have an unbranded S5 900F with an EE contact sim. Wanted to get the wifi calling working as signal crap at home and my missus has it working very well on her S6 Edge (EE branded).

My S5 900F was bought off ebay and it actually came with an AUT (Switzerland) firmware that already had wifi calling option present in the call options G900FXXU1POF4

Couldn't believe my luck at first when it arrived yesterday and I saw this firmware on it.

The option to enable wifi calling was present right at the bottom of the call settings page, under a green heading "Wifi Calling". I then ticked this option and rebooted phone. Texted wifi calling to 150, only to get a response saying visit the following page to find out more info blar blar blar.

Then phoned up EE, spoke to very helpful bloke (didnt ask once where i got the phone from, my contract is for an S4 still) and he 'enabled' it instantly his end, but nothing happened on my phone. He told me to wait 24hrs and see what happens, but it should have worked instantly.

24hrs passed and nothing, So I decided to try the EE EVR firmware (G900FXXU1POD1_G900FEVR1POD1)

I knew from reading that it wouldn't flash on an unbranded phone due to the hidden partiton size. I therefor used TotalCommander to delete the hidden.img file from the .tar, saved it and flashed with odin succesfully.

Rebooted phone, turned on wifi calling again and immediatley it was working (saw the phone/wifi icon at top of screen)

I also noticed that the setting on the EE firmware was called "VoWi-fi" (not "Wifi Calling" like the AUT firmware that didnt work)

So the wifi calling works great, but I still am not happy as this EE EVR firmware doesn't seem too good in other departments. When im not connected to wifi my cellular data connection is very unreliable and will often freeze even with full bars of H+ or 4G. Its an old build date maybe with a few bugs still, or maybe because I've deleted that Hidden.img is causing a few problems ?

Have tried a factory reset but dodgy data connection issue still here.

Wifi is fine however.

I guess my next plan is to update to a more recent unbranded firmware (without these cellular data connection bugs hopefully), and see if I can root and then use CSC master or something to enable and get the wifi calling feature working on an unbranded firmware.

Does anyone know specifically what lines need to be edited and in what files to get this working on a non EE firmware or even if it actually works ? - I know the setting can be made availible by editing the CSC features but do they actually enable the feature to actually work !!!! Remember the AUT firmware has it enabled by default, but that didn't make it work on EE !!!!!!!

Is there any files that i should copy or backup whilst ive got this EVR firmware with working Wifi calling that my help me ?
[Galaxy S6 Edge Q&A, Help & Troubleshooting] slickric21:
Just a quick update on the above mammoth post...

I spent several hours today messing around with this. Flashed the latest BTU unbranded firmware for my device, which was several weeks newer than the EVR one.

Rooted it fine, and then spent hours trying to get the Wifi calling option to show up by editing various .xmls in the "csc" folder.

Nothing worked.

Now back on the EVR firmware, least wifi calling is working, shame the cell data connection on OD1 is flaky. Guess Im stuck with it untill EE manage to get an updated firmware out.

Ee have released 5.1.1 with the stage fright patches included too... If you aren't seeing it OTA then smart switch should pick it up

I just ordered an S6 Edge today from Carphone Warehouse for delivery on Friday, guess I should have looked on here first. I needed to get the phone from there because they are simfree. If I got it from EE then it would be locked and I need a simfree phone.
[Galaxy S6 Edge Q&A, Help & Troubleshooting] rfangster:
You could always use an unlock code for the EE phone and unbrand it if necessary by flashing a stock ROM.
[Galaxy S6 Edge Q&A, Help & Troubleshooting] GTCC:
The phone is simfree so it is already unbranded. All phones(except Apple) from Carphone Warehouse are simfree.
[Galaxy S6 Edge Q&A, Help & Troubleshooting] FSOP:
Not experienced it first hand but ive heard car phone warehouse phones lock to the first network sim that's put in.
[Galaxy S6 Edge Q&A, Help & Troubleshooting] GTCC:
That is only with iPhones, all the others are simfree. I tend to get my phone from them because they will price match(and do a little better plus some extras) and I live between the UK, Italy and my home country of Ireland so I need to be able to change sims. The phone will be here later today so I will if I can get wifi calling to work then.
[Galaxy S6 Edge Q&A, Help & Troubleshooting] FSOP:
Ah, I've never had an iPhone from them so that'll explain why I've never seen it haha

To update to EVR firmware just use Kies and the steps HERE

I updated/crossed the firmware from 5.1.1 AUT and it worked after a few minutes :good: Got a text to confirm it was working the next day.
[Galaxy S6 Edge Q&A, Help & Troubleshooting] rfangster:
Unfortunately I have an S6 Edge, do you know of any serial numbers for the EE model?
[Galaxy S6 Edge Q&A, Help & Troubleshooting] FSOP:
Someone here must have an edge bought direct from EE?

Just incase anyone is worries about sharing their serial, it won't affect any sort of warranty etc in fact all someone could do with your serial is check your warranty info!

Managed to flash the official EVR firmware through FSOP's method - wifi calling works now even on airplane mode, and as slickric21 confirmed the option is displayed as 'VoWifi' rather than the usual 'Wifi Calling'.

I've tried various times on BTU firmware but nothing.

WiFi calling is enabled EE's side and mine

Don't particularly want to flash EVR as I was stuck on download mode last time I tried

What's the quality like? Also which method did you try to get EVR just out of interest?

Finally are you able to upload your features.XML

Thanks
[Galaxy S6 Edge Q&A, Help & Troubleshooting] CJ0206:
The easiest way I have seen is HERE to get out of download mode just press power+volume down for 7 secs.

WiFi calling for me has been 'HD' the whole time. I can't upload my features.xml at the moment sorry.
[Galaxy S6 Edge Q&A, Help & Troubleshooting] rfangster:
I've also tried importing the EVR CSC into the BTU firmware, it just doesn't work unfortunately. Seems like something else also needs to be enabled. I haven't noticed any difference in quality compared to calling via mobile network, and I have noticed that the phone app suggests it is 'HD'; I haven't tested the feature enough to tell. Interestingly, wifi calling seems to automatically disable when wifi signal is weak. As for features.XML, I can't actually seem to find this on my phone.
[Galaxy S6 Edge Q&A, Help & Troubleshooting] Ronny220:
I have the HD voice feature enabled which works fine, this shows a 'HD' icon when talking to someone who has EE and 4G.

Just can't seem to figure out the WiFi calling sadly
[Galaxy S6 Edge Q&A, Help & Troubleshooting] rfangster:
You really need to have the EVR firmware, follow FSOP's method which works well. It seems it's the only way to get it working for sure
[Galaxy S6 Edge Q&A, Help & Troubleshooting] Ronny220:
I'll give it a try again...anyway to preserve data and settings don't particularly want to start from scratch again

Could try a dirty install via odin but don't know if that will cause issues.

Does anyone know the latest UK version which has the apps edge feature added?

EE are terrible for updates that for sure!
[Galaxy S6 Edge Q&A, Help & Troubleshooting] rfangster:
You can't flash the EVR firmware with ODIN, you have to use Kies unfortunately and also it will wipe your data, do a backup through Helium first if you don't have root. The edge apps feature is only available on Samsung's newly released phones for the time being, but you can use an app like Glovebox which I personally think is better.
[Galaxy S6 Edge Q&A, Help & Troubleshooting] FSOP:
The only extra bundled apps on evr I can see Is the myee app, which I use anyway but can be removed if you want.
[Galaxy S6 Edge Q&A, Help & Troubleshooting] Ronny220:
I have tried to use Smart switch and clicked on software update and initialisation. Keep getting error 'the model information that you have entered cannot be verified, the device initialisation cannot proceed. Please contact the service center'

[Galaxy S6 Edge Q&A, Help & Troubleshooting] lynxblaine:
So has someone got this into a clear defined guide, CSC changing requires root? There is some mention of flashable zips but that seems hacky when new OTAs arrive. I have an edge uk unbranded arriving tomorrow which I am deciding whether to try and get wifi calling enabled with the EE rom or not bother.
[Galaxy S6 Edge Q&A, Help & Troubleshooting] Ronny220:
I wouldn't bother unless you need WiFi calling...

There is a new update for 5.1.1 available, XEU firmware via Sammobile.

[Galaxy S6 Edge Q&A, Help & Troubleshooting] lynxblaine:
I used the method, found a serial number on ebay of an EE S6 edge, (can provide via PM) it allows you to get the EVR firmware to download and flash properly. I miss apps edge and I think the ram isnt as optomised but having wifi calling working is more important to me.
[Galaxy S6 Edge Q&A, Help & Troubleshooting] dwmw2:
I managed to flash the EVR firmware on my unbranded S6 without having to repartition. The bloatware in the larger hidden.img didn't fit, but that doesn't matter; nothing in there is relevant.

I now have Wifi Calling working; I can make calls and send texts, and watch the IPSec traffic over my ADSL line with a packet sniffer.

If you're using an unbranded firmware, it looks like it's not sufficient just to enable the CSC feature; you also need the configuration. I think that's actually in the cache.img from the EVR firmware. It contains a sec_csc.zip which is applied at first boot, which contains an IPSec service package and libjni_ipsecservice.so.

Perhaps someone could try installing that update on a BTU firmware, and see if it makes Wifi Calling actually work (as opposed to just displaying the menu option).

Even the unbranded S6 firmware doesn't support native SIP calling, does it? If it did, I might be inclined to experiment further myself and get Wifi Calling working on the unbranded firmware. For now I'll just stick with the EVR firmware I've flashed.

i did the same. but not working yet. did you have to wait a while until activated or was it instant.

i have checked the serial number after flashing evr rom and its my original one not the one i put into smart switch to install.

very confused and annoyed as this is a huge reason why i got the phone, but unable to get it working.
[Galaxy S6 Edge Q&A, Help & Troubleshooting] lynxblaine:
I installed the software. Then once I had restored my data, enabled the setting under (settings>applications>phone>Vowifi>WiFi calling ) texted 'WiFi calling' to 150 wait like 1-2 hours and got a text to say it was enabled. If you have done all of this then call 150 and check it's enabled.
[Galaxy S6 Edge Q&A, Help & Troubleshooting] dwmw2:
I got the EVR firmware from http://www.sammobile.com/firmwares/download/52464/G920FXXU2POGM_G920FEVR2POGN_EVR/

The important part —or so I hypothesise — is in the src_csc.zip "update" applied on first boot. You can download the whole firmware image and then use simg2img to extract 'cache.ext2' from 'cache.img' and then mount it and get the file. Or you can download it from http://david.woodhou.se/sec_csc.zip

It lives in a /recovery/ directory in the cache filesystem, along with a file named 'command' which contains the following:

--update_package=CACHE:recovery/sec_csc.zip
--carry_out=csc_home
--wipe_cache

I think the update-binary therein will use dm-verity to check that the system image hasn't been modified, and bail out if it has. You might be better off just dropping the files from src_csc.zip in place as it might not actually apply as an 'update' on anything but a clean system.
