T-Mobile WiFi calling optimized ROM?

I have been looking for an optimized T-Mobile WiFi calling ROM, looks like no body cares about this feature because it is only few ROMS using this feature. I am using the stock rooted but it is bad with the battery and I am used to the battery use in Chrome ROM. Could someone point me to a good rom with the best features and battery with a WiFi calling enabled? Thank you.

its only available in stock(or stock based ROMs?). its added in by tmobile, and not open sourced(yet?). and the majority of ROMs are based on aosp, and the code wasnt put into aosp(yet?). so if you want WiFi calling, you'd have to use stock, or m.

I was about to post the same question... any answers?

The wifi calling bits aren't part of AOSP, a few people have tried to "reverse engineer" it, but with limited success from what I understand. I think part of the problem is finding a developer that has T-Mobile. Being that some of our devs are from all around the world, and even the ones in the US are likely not going to have T-Mobile. This makes their testing slower and/or harder.
I think there are a few that are still working on it, but I don't think it is a major focus of anyone. I know a couple have sorta given up on it.
tl;dr - No custom AOSP (or variations of it) currently have it that I know of, stock ROMs are the only ones (plural because this includes M dev preview) that offer the functionality.

I'm using the m preview with newest radio and it works great

You can get the factory images directly from Google, here. Or there are versions you can flash in a custom recovery and slightly customized versions floating around these forums.

Try the JDX M preview rom here on XDA. Rooted, unencrypted, busy box and a few other fixes. Load that and hellscores latest m kernel and you are good to go

Is there an updated list of roms that have WiFi calling somewhere? I googled it and found this thread but that's it.

No. Just about any ROM that has been updated in the past month or so should have it built in. The OP of every ROM should state if it includes it, and if it doesn't then there is a good chance it doesn't.
Just as a note, kernels also matter for getting wifi calling to work as well, if you decide to flash a different than what is included with the ROM.

PureNexus is optimized for Project Fi now, and T-Mobile calling is working fine. Been my daily driver since the first release July 5... I kind of miss crack flashing, but it's stable and has lots of great extras! Plus the Dev and community are super helpful!

You'll find WiFi calling in Dirty Unicorns, and in PureNexus as has been already noted, plus Chroma, I believe Minimal OS, AOSiP, as well as most stock based custom roms (include Gapps)...from what I can tell, no Cyanogenmod based rom has it...I'm sure there are others.
Best to flash and try it before fully setting up the rom itself. Here is why...if the feature is important to you, it can take a bit of tweaking to make sure it works...for starters, if going the AOSP route, you'll need a WiFi calling kernel (Lean kernel version 2.10.6 works perfectly), a proper T-Mobile WiFi calling modem, and those include 14R, 16R and 17R...and sometimes you'll need to toggle WiFi calling on and off, reboot, and you also may need to dive into developer options and flip the switch aggressive WiFi to cellular handover.
Good luck!

No, I tried looking for a how to or something on it, I might try some time, I don't know exactly what it entails.

@superfes
Thanks for releasing unofficially CM12.1. I'm using it since yesterday and its working fine so far. However, I get settings fc sometimes and mostly on bootup.
Another issue is with camera focus on micro shots which makes the device force reboot. It was present in cm12 long ago but it was solved or vanished later. Now seems to be back on CM12.1
Of course without a log, we cannot figure out these issues so I will post it asap here.
Btw; thanks for including d2s feature in the kernel. I have been missing it for long on official CM ROMs.

Tested IR and its working fine, including recording. I'm using latest version of Smart IR Remote - AnyMote.
Best Regards

For some reason I wasn't able to receive calls. They said it rang once then went to voicemail. IR also wasn't working through peel but I never really use it. Other than that OMG the ROM! This is the only CM rom that doesn't have issues with my FFC on official CM it has a weird tint to it with every app

Everything works great other than the camera. Same issue as most here, using the camera most of the time results in a reboot of the phone.

Flashing the 2015-6-22 build right now! I'll update after it's been tested.
update: the camera seems to work fine, and doesn't cause reboots now. But I get random reboots just out of the blue. And that was happening before the update. But issues with the camera seem to be fixed. So that's awesome!

I'm gonna transition from official cm12 nightlies to this build. I am also gonna try the 20150602 cm 12.1 gapps build (located on http://wiki.cyanogenmod.org/w/Google_Apps) since this is a newer version..hope it works. will try to post any issues. If you don't hear from me, assume it is working great! Thanks for this build superfes.

OK loaded fine with newest version gapps, so far so good

I too confirm that force reboot in camera focus is now fixed. Thanks a lot.
However, wake features are no longer available. Looks like you have changed the kernel.
Can we use the kernel from the previous build of yours?

I was trying to fork this one: http://forum.xda-developers.com/sprint-htc-one/development/kernel-elite-kernels-t2961835
But I messed up a merge, I'm trying to get it back to working, as soon as the merge is stable I'll build it back in.
Until then you can just use the AOSP kernel there.

Hi
I like this rom so far, but I was hoping to reinstall the Beats sound back. I downloaded the apk, but it says an error when I try to install. The music through the speakers sound rather tinny without it. Has anyone installed Beats or anything similar to improve the sound quality?
Thank you.

So I have been using this rom since the 25th as a daily driver, I actually have had only 1 random reboot (unlike on the cm12 rom I had previously where it would reboot almost every day) Camera seems to work flawless where some have reported that it reboots but is def fixed.
I am having one major issue where I get no service 90% of my day, and I only get an exclamation point next to my service bars. The only way to *sometimes* get it back is by going into my mobile network settings and toggling the preferred network type back and forth from global/CDMA + LTE/EvDo/EvDo only/CDMA w/o EvDo/GSM only (where GSM only was to force it out of the proper net type and back in so I could toggle it back to CDMA base right after) And sometimes that didnt even work. I would also toggle airplane mode on and off with similar results. It is quite frustrating. Does this have anything to do with the fact that I never updated my stock radio/kernel? Does anybody know a fix to this? GPS also isn't working (and hasn't been for over a year)
Other than that everything else is working great, best CM12+ rom out so far! Please, if anyone knows of a solution to my connection issues please share! Thanks!

Custom 5.1.1 Rom that supports Ok google everywhere

HI,
I am looking for a 5.1.1 based rom that has Ok google everywhere working when screen is off.
I have tired quite a few of them and different Gapps but seems that Ok google everywhere is broken.
I cannot record the ok google command. It always says there is some noise. ( inspite of being in a very silent room )
However Ok google works in the google search app and nova launcher .
Any suggestions.

I was only testing out the CM based roms and okgoogleeverywhere does not work in any of the recent one. Could be something recent has broken it.
However I tested ASOP based ones and in all of them ( slim rom and purenexus ) it works well...
I am dont know how to figure the issue out with CM roms. Hopefully someone will..

cm is a constant work in progress, so its normal for cm to break things, only to fix them later on. besides, last november it wasnt working on aosp either, then we found that aosp was missing certain files to make it work, by default. since then, its always worked on aosp.

I tired flashing those files that was posted in another thread but did not make a difference.
I guess it was asop only.

Just got a Droid Turbo - Bootloader Unlocking question, plus ROMs (besides CM12)

Just got a (supposedly rooted) Droid Turbo off Ebay... looks real nice. The phone was advertised as rooted, though i'm not sure how to verify. Android version 5.1
I had planned to install a custom ROM... initally CM12... as I want to tether with the device. I have CM12 installed on a Kindle fire and it works well, and I've installed custom ROMs (CleanROM, specifically) previously with an HTC One M8 (go S-off, unlock bootloader w/ sunshine, twrp recovery, etc), and it worked well.
I did note in the CM12 thread that simultaneous voice + data isn't supported right now. Thats a feature I use a lot, so I'm wondering if any other ROMs are out that support both tethering as well as simultaneous voice/data. (ideally ones with continuing support, but hey, can't be too picky). Maybe not a deal breaker, but it'd be a concern.
Also... I was expecting unlocking the bootloader to be a big deal (or at least to require another paypal payment to sunshine). Looks like I have an "allow bootloader unlock" option in developer options. Is that all I need? That'd be sweet!
Thanks all!

Custom ROM list is here. All the Quark ROMs work on all the Quarks -- including the Droid Turbo XT1254 (with unlocked bootloader):
CM12.1 ( @Skrilax_CZ dev)
Resurrection Remix ( @baybutcher27 dev)
Mokee (AOSP ROM, @baybutcher27 dev)
Nexus Experience (AOSP ROM), (EDIT: Nexus Experience has not been updated recently and does not work with Droid Turbo radio.)
Xperia Z5G
as well as custom kernel BHB27 ( @baybutcher27 dev).
Droid Turbo owners are using all of these above.

There's also ComputerFreak274 stock ROM with tweaks here:
http://forum.xda-developers.com/droid-turbo/development/computerfreekunlocked1-0-t3255945
As of this moment, that's the only one that does VoLTE on Verizon. The others including CM and Resurrection Remix have the VoLTE flags and all that, but for some reason right now it's not working on Verizon. The devs haven't given up yet.

That exploit will be patched with the OTA update. In fact, I wouldn't take the OTA update at all, even if your bootloader is unlocked. Let others take the risk.
Once Marshmallow hits, all the ROMs will be updated to Marshmallow. Use those.

You'll end up with a lot of answers on this because everyone uses their phone differently. Honestly, I tend to try about any ROM for a day or two or maybe a week at most just to see "what's new". In the end, I end up back with the latest stock OS / Magisk / Xposed, and a custom kernel of some sort as I've found this the most "stable" for my use.

I've tried quite a few, but EX seems to work well overall (also has a nice kernel manager). One thing to remember, if you are trying different kernels, make sure to flash the stock one in between.

I found this on another website, not sure if it will help you or not:
Here’s how to do enable VoLTE on your Verizon Nexus 6.
Step 1. Fire up your device’s dialer. And dial *#*#4636#*#* to access hidden menu.
Step 2. Now, select ‘Phone information’.
Step 3. Next, tap on the TURN ON VOLTE PROVISIONED FLAG button. No changes would occur though, and it’s fine.
Step 4. Now tap on the TURN OFF RADIO button.
Step 5. Wait a few seconds now and let radio get turned off. Then turn the radio on after that by tapping TURN ON RADIO button.
Step 6. You’ll be able to see that TURN ON VOLTE PROVISIONED FLAG BUTTON is now changed to TURN OFF.
Step 7. That’s it. Now go to Settings > More > Cellular networks, and keep the Enhanced 4G LTE is enabled.

There is no one best ROM for all users, it's a matter of personal preference. I run Validus Oreo on my shamu
