Hello,
Is there any one using the ATT GS5 on Tmobile network (obviously Tmobile SIM) with wifi calling working ? (Please..please.. I know ATT does not have wifi calling, But if you use a Tmobile Rom with Tmobile sim, you expect to have it working) !!
If yes, would you please share which ROM you are using ? Also if there is a trick to make it wok please share it?
Thanks
no luck so far
This is not a solution, I just wanted to report what I have tried so far.
I have a G900A with a t-mobile SIM card. I called TMO to make sure wifi calling was enabled on my line. I used towelroot + safestrap to install the t-mobile Alliance rom (B4), as well as the latest stock TMO rom. So far, wifi calling does not work. It is always stuck on "Enabling" in the calling options menu. VoLTE doesn't work either, but I wasn't expecting it to. My guess is that there is something in the TMO baseband that makes these things work and that ATT phones don't have.
Any hints and ideas would me much appreciated!

JJ here,
I tried this ROM - [ROM] G900TUVU1BNH5 ported from TMobile, rooted, deodexed, no knox, Download Booster
... everything works, nice and smooth, but the Wifi Calling is stuck "Enabling"...
Same boat.

Yes. In particular, Mobile Hotspot will work.

Will everything else work properly? I mainly need the t mobile stock rom to enable mobile hotspot, I have an ATT phone and do not wish to trip efuse. Thanks
does anyone know if the same issue will happen with the international version?
On a similar topic, my dad has a AT&T Samsung Galaxy S5 which was sold in Malaysia. And I found out that his phone was not able to hotspot. I have downloaded the official firmware of Samsung Galaxy S5 for Malaysia and was going to use Odin to flash the firmware into his phone. Does that work and not brick the phone? The phone seems to be unlocked as it can be used here except the firmware and the phone is AT&T barnded. Any advise? Thanks

It all works!
Guys, I have some great news. Both wifi calling AND VoLTE now work on my SM-G900A on the T-mobile network. Here is what I did:
I installed the latest ATT firmware (OA1), released earlier this February. OTA update did not work, so I had to flash the original firmware (ANCE) via Odin, and then flash the two subsequent updates using update.zip on the SD Card. This will remove safestrap and root, but fear not.
Once my phone had AO1 installed, I used this tutorial to root the phone again. It invonves temporarily flashing an earlier (ND3) kernel, using TowelRoot, and then reflashing the OA1 kernel
With my OA1 rooted, I installed safestrap. Make sure you install busybox first.
With safestrap, I installed the T-mobile Alliance Rom (build B4).
Seconds after booting, both Wifi Calling and Voice over LTE work!
Enjoy!
Guillaume
Hi Guillaume,
Have you tried just installing the stock T-mobile 5.0 firmware on a Att GS5 ?
I have my GS5 in ND3 rooted and I'm on Tmobile, but the procedure you have seems really long...
I really need wifi calling as I'm travelling a lot and it allows to call my wife when I'm back in France.
Thanks

Thanks as this is great news for us G900A users on TMO! Question though: After 0A1 installed/backedup and Alliance installed, did you use safestrap [TWRP] to restore your data from 0A1 install?

Actually no; I had been using the t-mo alliance rom using safestrap for a long time (just with the old ATT modem and kernel), so I just restored the data associated with that.
Some more info after a day of tests:
You can also install the 5th build of Alliance Rom, it works too
The camera sometimes glitches a bit; toggling HDR on/off fixes it
Except for the camera glitch I'm pretty happy with it!

I might to try to create a flashable zip from the latest t-mobile lollipop release, keeping only the /system files, and see how that goes. This is really a shot in the dark, hoping that the 4.4.4 modem and kernel from ATT somehow work well enough with the t-mobile lollipop rom. Damn you locked bootloader!

Agree with the last expletive.
I did install in alliance B4 in slot 1 of Safestrap and both wi-fi tether and calling worked well. However, my G900A would not reboot or shutdown (dark screen) without a battery pull. After power up...worked?!?!
Did you install as "Stock" or in a slot?
Also have a G870A (Active). Do you know of anyone attempting the 0A1 method and Alliance Rom with the s5 Active?

What would happen if I odin a Stock T-mobile firmware and let T-mobile update it ?
Will it update the Baseband etc ?

I only use the stock slot.
B4 seems a bit more than stable than B5 for some reason. I get some signal issues with B5, and the fingerprint scanner sometimes fails. (It works when I first install B4, use it for a while, and then upgrade to B5. But if I do a /data wipe on B5, these issues appear. I have no idea why).

You can't do that, the bootloader is locked.

Okay thanks,
So I started the steps, I've Odin the original firmware and factory reset on but my baseband stayed ND3...
Tried the OTA update hoping that it would work, but as expected it did not.
So I guess I'm at step 1 of your step one.
Then you said you pushed the update via sd card, where did you find the updates ?
Then I'll do the other steps!
Baby steps by baby steps, F... it's been a long time since I rooted my ipod 1st gen to crack my ps3!

They are in the post that I linked to, under the troubleshooting section. If you want to keep your user data, use adb sideload instead of recovery

OK. Installed in stock slot but ROM behaved much differently.
1. Wifi sms/mms work both send/receive but erratically.
2. Outgoing calls connect then immediately drop with local "cancelled" within a few milli-secs with a partial ring at the far end.
3. Can't receive calls at all. TMO network thinks I'm offline even though can receive a text.
3. Phone App GUI stutters when making a call.
4. Camera is basically not usable.
Where there any special steps you took to get this working installed in the stock slot? Has your install remained stable? Thanks in advance.

My phone is still working flawlessly. What your are describing is what happened to me during the short period I reverted to the NG3 kernel in order to use Towelroot. Did you make sure to reflash the OA1 kernel once you were rooted? (before installing safestrap and, within safestrap, installing the Alliance Rom). I have found Alliance B4 to be more stable, so you could try that. Finally, a factory reset (wipe option in safestrap). Beyond that, you could try the whole thing again: flash the "downgrade to NCE" rom, which will remove safestrap and clean everything up; and take the tutorial from there.

Thanks again Guillaume,
Was running OA1 prior to Alliance B3, so just wiped Dalvik and Cache again, rebooted and left phone for the night. By next morning all was well except for the camera HDR issue. Once toggled it is OK until closed and reopened. Haven't had the time to look into whether there are Alliance B4 options which may affect this.
Have run it a few days and have had zero issues with Wi-Fi calling or tethering or apps: a very smooth experience.
Thanks again for your contribution. Also muniz_ri will find a bottle of wine on the doorstep soon. :highfive:
So I went back to completely stock/encrypted to flash the new 5.1.1 update with Wi-Fi calling. I want to stay encrypted but I want to re-root my phone. Anyone running the new T-Mobile 5.1.1 build (LYZ28E) with root and having any problems with Wi-Fi calling? I just want to make sure it won't break it if I root... it would defeat the entire purpose of going back to stock.
Thanks!

Flash SuperSU and report back to us, let us know if it works. You can always unroot with ease via SuperSU settings. There is a cleanup option.

I could, but I thought I'd ask to see if anyone else has done it first.
My biggest concern is that I have yet to see Wi-Fi calling work. I flashed my phone at work using NRT and I am connected to Wi-Fi, and I have enabled Wi-Fi calling (set to Wi-Fi preferred) and I'm not seeing any evidence anywhere that it's active. I'm probably going to have to wait until I get home and try my Wi-Fi there.
My phone is rooted and wifi calling is working. BUT i have several ap's at home. before i had no issue handing off from one ap to the other. now, i have to disable wifi and re-enable to connect to the closest ap. also, the update has completely stopped giving me notifications on my moto 360
No problems for me.
Hello everyone. I did the root on my Galaxy S6 edge, and everything's been working great. The only thing I really use it for right now is so that I can run my app radio unchained reloaded app. Otherwise I haven't changed anything. Recently I've been getting carrier updates coming in that I have not been able to accept. They continue to fail. Is there a way I can update my phone yet still keep root? Or is there something else going on?

You can Odin back to stock (oc3), take update, then root using latest ping pong root. Or, flash a custom oe2 rom using flashfire, then use Odin to update firmware to OE2, such as is explained here: http://forum.xda-developers.com/showthread.php?p=61198002. Or use smart switch to update, which will remove root.

I recently bought a factory unlocked N910T off eBay, and it is running Lollipop. Both the OTA update module and Kies say it has the most recent firmware. We all know that is not true! Any idea what's going on? Is there something fishy or wrong with this phone? All the T-Mobile stuff like wi-fi calling and visual voicemail work fine, and the S-Pen hovers and everything so I'm sure it's not counterfeit. I presume I can still flash a stock rom through Odin or something, but I'm really bothered that the proper channels aren't working. Thoughts?
PS: My old N910T (broke the screen) got the updates just fine.

Hi, I face the same scenario you described, no updates available thru official channels.
Did you already tried flashing the latest firmware thru Odin?
UPDATE: Downloaded the latest firmware with SamFirm and installed it with ODIN. No issues, my phone now haves Marshmallow.
