What do you mean Stock ROM? Are you talking about a Vanilla ROM made for the Vibrant (which there are none yet) or are you talking about the Vibrant version of Touchwiz. Either way they have different stuff that will not allow a simple load of it. There are many codes that would have to be changed to work on the Captivate. Its the firmware that will not allow it, not the hardware.

[Q] AT&T S4 Active - use T-Mobile and want Wi-Fi calling

As the subject stated, I have AT&T version of the Galaxy S4 Active. The phone is unlocked (code provided by AT&T) and now I have a T-Mobile SIM card.
I want to do Wi-Fi calling, but couldn't find any information in this forum or when Googling it.
Can anyone provide step-by-step information on this? Preferably, I don't want to install a custom ROM - I use stock ROM (rooted) and it has been stable so far.

Check this thread for T-Mobile WiFi calling ( http://forum.xda-developers.com/showthread.php?t=2302313). You've got two things working against you though. First you have the AT&T version of the phone, so ours locked down and you can't fully flash ROMs to the phone. You can use SafeStrap to flash ROMs but because of the bootloader being locked your stock with the stock kernel. Second, nobody has got T-Mobile WiFi calling working on non T-Mobile ROMs. So basically you can't do it with the phone you've got.

Thanks for the detailed information. Looks like it's not doable given the locked boot loader. :sly:

T-Moble 920T SIM Unlocking and keeping WiFi Calling and VoLTE (Can it be done?)

Guys, I have a question for anyone that's SIM unlocked their 920T's. At the moment, my 920T is running xtresolite 2.2. It's based off a 920F firmware. As you know, this is an International version. To further complicate things, I needed to SIM unlock my phone so right now I'm using the MetroPCS COF9 baseband. Every time I switch back to a T-Mobile based ROM, my SIM unlock gets pulled and the phone is relocked back to T-Mobile (has been confirmed in multiple posts on XDA). I'd just stay with xtresolite 2.2 but I have no wifi calling or volte. I'm trying to find a rom for this phone that supports a different carrier sim as well as volte/wifi calling when I switch back to my T-Mobile sim. Is this possible?
All the ROM's I find for the 920T are either locked down T-Mobile ROM's under that development section and the general development section is mostly compatible International variants - but lacking WiFi calling or VoLTE. I'm beginning to think these two things just can't work together on the same ROM.
Thanks so much in advanced for a reply!

If you want unlock while on T-Mobile rom. See here: http://forum.xda-developers.com/tmobile-galaxy-s6-edge/general/sim-unlock-t3186826/post62512066
Other than that, not sure about WIFI Calling etc

voLTE

Hi there, proud owner of N920I here.
I have been flashing plenty of roms and i realised that most of the roms lacks the voLTE feature.
I would appreciate if anyone can advice me on how to get back the stock Phone APK (Singapore Singtel) with voLTE option is the phone settings.
Thanks in advance for those being helpful ^^

Stock firmware. Or flash a rom that supports it.

I have flashed stock rom, ap/bl/csc/cp but still can't find my voLTE settings. This is really weird. I am unable to get back my stock telco rom, googling gives 0 results lolz

Same on 920i in US. Is it because either att or tm doesn't support our variant? I wish it would support samsung pay more than volte.

For my case, I have voLTE when I purchased it . After rooting and going back to stock (same firmware same CSC same modem n bootloader) I can't find it anywhere pretty weird. On stock I have 4g+ but on dr ketan rom I only get 4g. Flashing CSC and modem over doesn't change anything other than the phone apk layout lols.
Anyway, once rooted, just forget about Samsung pay.

Will I be able to flash a rom that supports the t-mobile/metropcs VOLTE?

Hello everyone! How are you all today? I hope this day finds you well! My question is, if I downgrade my at&t s6 active to 5.0.2 and root it, then will I be able to flash a rom to it that supports the t-mobile/metropcs VOLTE and wifi-calling? I use metropcs, and I got a good deal on this unlocked phone, but I didn't know the at&t Volte works differently than metropcs, and as a result my service has worsened.
