Okay, so you guys probably already found this:
Software binaries for AOSP Android 12.0 – Kernel 5.4 – Sagami (v1) - Sony Developer World
developer.sony.com
My question is if that could work with the newest update to enable wifi calling with T-Mobile in USA? I love this phone, but I have to get wifi calling to work properly like all my other phones do. I live in the mountains using starling internet and the digits app is unreliable for me but wifi calling works great. I saw a Reddit thread saying that installing the developer binaries on an Xperia 1 II allowed the the wifi calling to be turned on.
Any help toward this goal would be greatly appreciated! Thank you.
And I am posting this from an Xperia 1 III running the 61.1.A.7.35 firmware all stock.
Which Variant do you have I bought mine from Amazon but I flashed the SEA firmware and have VOLTE turned on but can't find WiFi calling
Okay after scouring Reddit I found this:
Came across this 9 months later while searching for a resolution to VoWIFI.
Google Fi WiFi calling works on all Android phones, because they don't rely on network-provided VoWiFi. Instead they redirect calls directly within the Android phone subsystem.
AT&T and Verizon enable VoWiFi only on supported devices. T-Mobile VoWiFi should work with any compatible device (and *does* work with the Xperia 1 series if you flash Sony's developer firmware on it), but in the production firmware this seems to be disabled by Sony.
End quote.
So...that's probably why...
Mine is the North America build. I don't need much from this phone, just working calls, texts and internet for business purposes. No android pay or special stuff. So if the developer binaries could make wifi calling work, it is worth a shot.
XQ-BC62 is the variant.
So if anyone could point me in the direction of how best to install the devoloper binaries, I will give it a go. It has been many years since I have done custom roms, adb & rooting type of funtivities on my old motorolas, so I am sure there are a few things different with this Sony that I want to do correctly.
Thank you!

Lol I've been out of the game since I sold my LG V40 just to be told my Galaxy S10 wasn't rootable since it was a snapdragon variant .-.
So the final working solution turned out to be the round Starlink dish that came with one ethernet port, which feeds into wan port of TP-LINK AX4400 with updated firmware, then feeding into T-mobile personal cellspot via DMZ ethernet port. It took a few hours of blinking lights for the background setup time on the cellspot to download updates but it works fine now with all green lights.
Still no wifi calling, but everything else works like it does in town, including calls through the cellspot without flashing or rooting, so good enough.
That's good to hear my guy

Hi folks,
I'm looking to possibly switch to T-Mobile, but I know that coverage is spotty in my home town. (I don't go home often... Maybe once or twice a month for a weekend)
Because of the spotty coverage, wifi calling is a feature of T-Mobile that is very appealing to me, but I've been hearing rumors that their wifi calling feature doesn't work unless you purchase the phone directly from T-Mobile (which obviously cannot be done).
However, I do remember seeing a screenshot of the Xperia Z5 Compact's wifi calling settings and there was a tab listed for T-Mobile. Now why would a phone include wifi calling options for a specific carrier if that carrier refuses to support that phone?
Now let's say there is no way to trick the Z5 into letting me use wifi calling on T-Mobile... I read an article stating that CM13 will support T-Mobile's wifi calling. If CM13 was developed for the Z5C, would that do the trick?
Praying that someone with some more experience can shed some light on this matter. Is there any hope for me?
T-mobile announced that they'll be giving mini towers to customers for free (that's not wifi calling but an actual LTE tower for your house that uses your internet connection) so you can just call them up and ask when they'll start sending them out.
Does it just generate an LTE signal? That works well if the phone had working T-Mobile voice over LTE; which i'm not sure it would if I purchased an unlocked model. That router would be great for my home, but I'm concerned for other areas of my hometown, where I actually would need service (for example: car accident). If I could connect to a local coffee shop's wifi connection to make calls; that would make my life so much easier. I would hate to only have service in my home because that would make me feel bound to my house.

It's only phone based: https://support.t-mobile.com/docs/DOC-24269
FYI, I did use T-Mobile on an unlocked, unsupported phone last year for few months and I don't recall ever not having phone signal. Data is another story but calls were always available and I do travel a lot across the world. Their international data is pure BS - it just doesn't work.
And finally, the T-Mobile WiFi calling menu you saw is for the old T-Mobile in the UK that has now been merged into EE. You can flash that firmware but it probably won't work with the USA version depending on what moron wrote the integration and how much configuration data they hardcoded in the app or if it works it might be connecting to a UK gateway.

It's not that I think the phone will not have service because it's unlocked. T-Mobile just doesn't have great coverage in my hometown area at all. I did the Test-Drive a couple months back and remember getting 0-1 bars at all times... never holding on to a signal long enough to make a single phone call or send a text message. Thanks for the insight into the T-Mobile - EE thing. I didn't realize that. It would be lovely if it did work in the USA but I doubt it The T-Mobile Nexus 5 (arguably one of the most modded phones out there) never got t-mo wifi calling so I doubt this will.
Thank you!
Just so you know, I flashed to EE (even though technically I'm on MetroPCS which is a T-Mobile subsidiary), and I couldn't find that screenshot in any of the settings menus, nor could I locate it via "settings, under device, call. UK EE" as someone suggested in that thread. I do have a "Device Connection" menu and a "Call" menu, but they're separate menus not nested in one another. And I can't find any menu or option that says "UK EE".
So, it sounds like no one can find any Wifi calling toggle in any settings menu, correct?

A couple people have mentioned seeing it...someplace. One person said he saw it under the pencil looking icon in the drop down shade, but I've never been able to locate it up there no matter what firmware I've flashed too. It appears to be pretty elusive.

It's probably checking for some condition to show the menu.
If you extract the EE firmware you would probable be able to do a text search for T-Mobile and find the apps that have that then decompile the one that sounds like the most likely to have the functionality (probably one with the word customization in the name) and check the logic which enables the functionality and even change and re-compile it. You would also be able to see if it connects to a specific gateway for the wifi calling and if so try to change that too..
Theoretically a company won't spend the money to develop different Wifi calling mechanisms for different countries and thus it should work but then again...

You can follow this to extract the system partition (system.sln) and get it's contents to your hard drive: http://forum.xda-developers.com/showthread.php?t=1723284
Then you can use your file explorer (on Windows or whatever your OS is) to search for a text string (make sure you tell it to look only inside *.apk to avoid getting too many results). Once you find the apk files that could be what you need you can then use this: http://www.decompileandroid.com/ to decompile the apps so you get source code.
From then on it's a bit trickier, you'll need to make your way trough the configuration and maybe even the code to figure out where they store the connection info or what exactly do they connect to (it looks like the app uses your sim card to authenticate so that shouldn't require any tweaking).
Or you can just wait and hope this is true: https://support.t-mobile.com/thread/81359 or maybe it's already in M : http://www.phone-probe.com/android-m-features-native-wifi-calling/
Oh is that all? Simple.
It might be easier to just locate the apps needed for US T-Mobile wifi calling from another phone and install them on a z5c with EE firmware since the core OS code needed would be provided by the EE firmware and the US specific stuff will come from the apps.
This has a list that might actually be complete: http://forum.xda-developers.com/showthread.php?t=2302313 and you can ignore any jar files that are listed since that should come with the EE firmware.
The fact that there is a z5c firmware that supports Wifi calling is what's important here - you have all the proprietary and OS stuff baked in, you just need the US specific bits/configuration.
I am thinking about purchasing the LeEco Le Max 2 to use with AT&T. I've been reading on XDA and it seems like the US variant is the x829 one. I'd love to have the 6GB RAM model but the x829 does not have 6GB RAM.
Is there anyone here using the 6GB RAM model without issues (especially getting LTE to work) on AT&T? or maybe T-Mobile? If yes, which hardware variant do you have? The x820/x821/x82x...etc? and from where did you buy your device? Please share the full link if you have it.
Also is there a guide that shows which bands each variant supports?
Thanks guys, really appreciate any feedback.
Google "le max 2 x829 128gb" you'll find many places to purchase a 6gb/128gb x829 for as low as $245. I have the 4/64 x829 running stock rom on T-mobile with full coverage on lte. To my understanding the only band that's problematic is band 20 which we dont use in the united states. I bought it for my wife who wanted a rose gold model which is not offered in the 829 but I forced the gold 829 variant on her because I wanted direct access to the 829 rom so I can do some deving on it. I'm ordering a rose gold 4/32 for her Thursday for $193. When it arrives I'm going to clone her rom directly to the 820 then take over the 829 and have some fun. As for the 829 we currently have she loves it, loves the screen loves the camera loves the new ui (I hate it but to each their own). Call quality is great, volte works and even wi-fi calling on tmo works. As a comparison my wifes last phone was a Moto X 2015 (xt1575)
@castuis Thank you for the information. Do you mind if I ask from which website/seller you brought the phone? also where are you seeing the 6gb/128gb for $245?
Got mine from tinydeal. Ali express for the 128gb but they bumped it up to $259 about an hour ago, plus you couldn't pay me to order from them, made that mistake a few years back.
I am awaiting a silver 6GB/128GB from coolicool.com.
My first order with them, but they have been conversing with me via email since I changed the shipping address.
I 'should' have it with the next week? I hope it arrives and has a good fingerprint scanner?
@fcreeves I'm thinking about ordering from coolicool as well. Did you order from the Hong Kong warehouse or the Europe warehouse? Can you please let me know the condition of the phone when you receive it and which variant is it? x820 or x821 or x822 or x829?
A friendly word of warning. Success with the phones on T-mobile is not an indicator of how well they will work on AT&T, even though they are both GSM networks. For example, if voLTE is important to you, you are very likely not going to get it on AT&T. It is not automatically provisioned on AT&T, unless they know your phone intimately (and they don't know the Max 2 from a tin can and a string.) The first line of tech support refuses to even enable it on "unlocked" phones. There's also no means for WiFi calling, via an app or otherwise, unless you count the microcell boxes.
I'm tempted to call "BS" on anyone who says they are using these features on AT&T with these phones, based on the time I have spent on the phone with tech support..
Under the right conditions (read: areas), the phones work great on the AT&T network. Fast LTE data, and decent call reliability. But if if you want the bells and whistles, and enhanced reliability, the Max 2 can't deliver what the more mainstream brands can on AT&T. Even when right next to a tower, with the Max 2 showing full bars, I am unable to make calls, while every major branded phone brought into that same area has no problems. So something isn't 100% with these phones.
@RandyT2 I really appreciate the feedback.
@fcreeves, I'll be waiting for a feedback from you on the phone condition & fingerprint scanner.
I do have X829 64GB in the Boston area and I just got the Straight Talk AT&T nano sim yesterday. Popped it in, transferred my #. Had to change my APN in order to get LTE working, but everything seems good now. I don't know about VoltLTE, but everything else seems OK (for the moment).
With Straight Talk you have the option to go either Sprint/AT&T/T-Mobile or Verizon. I was using AT&T on my Nexus 5 so I thought I'd stick with it. Not sure if Verizon would be a better choice, but I didn't want to wait for them to send me another sim to test it.
The main issue for me right now is getting the fingerprint sensor working and rooting/flashing my ROM which seems a daunting task.
@Wagmans thank you for your feedback, not sure why many have issues with the fingerprint scanner and some don't have issues at all with it. It would be good to know if it's a hardware or software thing.

Can you give me some idea as to the ROM and Baseband version of the X829 phones you have? I really need WiFi calling, if I wish to keep this phone (which I do), and the way I understand that the T-mobile Wifi calling works is that the ROM detects that its an option based on the connection with the carrier, and the option just appears on the phone.
I'm ready to ditch AT&T because I have a fairly unique situation which makes the phone virtually useless to me without WiFi calling. But I need to make sure that I'm not switching, just to have the same issues, or to find out that only the X829 version supports it.
Thank you!

I think it's more of a software thing. We'll know once I root/flash it if that's the case. The root/flash process for this phone seems so involved. A little overwhelming- I hope I don't brick it.

It's too easy to flash TWRP, flash a new ROM, root and do all the things you need with it. This phone is practically unbrickable as you have a guide that teaches you how to unbrick it. Still, it's as easy as it gets to play with it.
@Wagmans please keep us updated if you get the fingerprint scanner to work
Yeah keep us posted. I'm interested in this phone. I have a Samsung S5 which I love and still use with no issues, but I'd like to have dual sim and have redpocket 99$ per year plan and Freedompop free data on the other. This set up will end up saving me hundreds of $$ per year.

Or a human thing. I got my wife the x820 in January. Immediately flashed TeamSpain's CM13 understanding the stock firmware had fingerprint scanner issues. All that, and only to learn she rarely gets the phone to accept her print, but when I pick it up it works every time. So there is obviously a human print component in the equasion that determines the FP scanner works, in addition to hardware & firmware.
I pulled the trigger on the TinyDeal 64 x829 today for $202 for myself. Leaving the Moto G4 xt1625 behind as a backup. I'm sorry, 2 GB RAM on my Moto G4 is insufficient. We expect our phones to be computers, and they are, but we'd never expect to run 2GB RAM on a modern day desktop. I'd really like to see a 32GB model with 6GB RAM.

I'll fool around with it. I'm still confused as to exactly which ROM I should flash and still have US Straight Talk/AT&T compatibility? Would the stock Indian ROM work? How about the Chinese? I don't know what the differences are (needs to have English, obviously). It would be nice to flash a stock ROM and be able to get the software updates from LeEco (as opposed to being locked out with my modified 16s now).
Oh, and as far as I can tell, VoLTE/MMS is working for me on AT&T in the Boston area.
So to sum up, everything is good for me on this phone except fingerprint and new/better ROM. I'll see if I can resolve that once I get some answers as to which ROM to flash.

I'd say if you want updates from LeEco, then don't flash. IMO security updates are really what's at stake.
Ideally:
(1) you want a stable rom with all the bells and whistles to make you happy, and
(2) the dev is updating the rom every MONTH with google's security patches.
But we don't live in an ideal world. TeamSpains CM13 rom may be the best google stock-like rom out there, but it appears not to be 'updated' anymore. It's very stable and everything just works. So from a performance standpoint, it's great. But from a security standpoint maybe not. But then again, branded carrier phones sometimes never get security updates

As far as I remember, the Chinese one has no limitations such as SIM1 4G and SIM2 only 3G or less. I'm using the Chinese one for quite some time and I'm happy with it. The Indian ROM has Play store but will add an encryption to your phone. In case you want to flash something again using TWRP, you have to format internal memory. The US version that was leaked 3-4 months ago had a limit of 4G on SIM1 only and 3G on SIM2.
Once you will flash the ROM, don't root it, otherwise you will not receive updates and you have to flash the new official stock again when it comes out. Search "manual gapps" to install Play Store on it.
Any ROM has English on it, even the Chinese, and it's not "translated"
About the AT&T compatibility, I'm not so sure. Maybe somebody from US can help on that matter.

Hi all, sim unlocked s-off sprint m9 used to work well on android 6 with official rom. But until the phone was upgraded to Android 7. Data connection stopped working for one operator (NOS in Portugal). However Vodafone works well.
Tried different roms and apn settings, same at all. Data connection does not work on NOS operator.
Does anyone have similar issue and of course any advices?
Thank you all.

Why sim unlock a Sprint variant and not an AT&T or T-Mobile which already support GSM?
did you find a solution?
i have exact same issue.
bought one m9 from ebay with sprint (651) firmware on.
lte was working fine in israel (1800 2100).
after nougat im only getting 3g.
it makes sense that i cant use those bands (1 and 3 i think) on a sprint device.. but it did work with marshmallow
Same problem in the USA
I have (nearly) the same problem in the United States with a Sprint CDMA version of the One M9. The main difference is that my data speed is even worse than 3G, around 10-20 Kbps. Occasionally, I get faster speeds, but I haven't been able to figure out if it is location-specific (but always away from home and work) or due to some other characteristic.
The phone came brand new in a retail box from an eBay seller. It worked as expected for 1.7 years. The OTA update which installed Android 7 (aka Nougat) in early 2017 resulted in the very slow data speeds. WiFi is unaffected, but data is so slow that I cannot reliably send or receive MMS; Google Maps says that I do not even have a data connection for traffic info.
EcoMobile (my MVNO provider; I still have a sprint email address, so I know who is actually providing service) could only suggest resetting my phone; did this twice with no change in operation (but several of the programs which automatically re-installed themselves operated differently, including GMail no longer providing auto-complete for addresses).
After literally 2 hours in chat with htc, they told me that my MEID indicates my phone was "made in Taiwan". I took this to mean that: 1) the person I was chatting with had poor English skills (because aren't they all made in Taiwan?), and 2) my phone is gray market (meaning it was not imported into the country via official channels, even though the manual was in the American version of English).
I came to XDA looking for an answer, too. I was mildly surprised to see that this topic was at the top of the list for the One M9.
The best solution for my situation would be the proper ROM for my phone, but I don't know how to figure that out from the MEID. htc USA says they cannot help me with this.
I could even go back to Android 6, but I do rather like the new features in Nougat.
Alternatively, I could root the phone and install a 3rd party ROM, but I still need to know how to choose the proper one for my phone.
I hope this info finds its way to a helpful expert.

Jeff
Hello - I've been trying to research how I can get Wifi calling enabled on my 965F but I get all kinds of twisted up with all the different model numbers and lingo of flashing ROM's so I'm hoping something might be willing to point me in the right direction. I have a brand new S9+ 965F model with the Exynos processor on T-Mobile US. The Wifi calling option is missing which I did not expect but after reading is not unusual. I keep reading about needing to flash a particular ROM in order for it to be enabled - something about XEU or U1 perhaps? I'm of course a bit worried about turning the phone into a brick but I'm willing to take a reasonable risk to get Wifi calling unlocked.
Can anyone help? I would really appreciate it!
I have an ATT one with snapdragon, looking for the same, enable WIFI calling mine is a G9650
Same issue
Hey Mate,
Have you find a solution for your problem? Got the same issue with my G965f/DS. Moved to US and Wifi Calling wont work on TM and ATT. I've even tested on smaller providers and still same problem. I travel a lot and need Wifi Calling when I'm abroad.
Please, let me know if you guys have any solution for this problem.
Thank you,
Unfortunately I ended up returning the phone. After hours of digging the bottom line I believe is that there is no carrier profile for US carriers in this version of the phone and then I think the next issue is it doesn't support the proper bands. I ended up getting the OnePlus 6T instead.
I read flashing a ROM from a country with VoLTE and Wifi calling enabled, lets you see the settings.
I have an s9+ from UAE and I'm waiting for Pie release on INS ROM (India) to flash it and see if it works in my country (Argentina)
Sent from S.G. S9+ Duos
I'm in the same boat, no knowledge of if or when WiFi calling will be available for unlocked phones. Just a shame that such an important feature that worked on my old iPhone 6 isn't available in a supposed "flagship" product. That's just really shoddy workmanship.
Hey everybody,
So recently i bought this international unlocked Galaxy S9+ (SM-965F/DS Exynos processor) off Amazon and it's great, everything is fine with the one major exception being that at home my signal is pretty poor and i get extremely delayed text messages coming in and calls taking forever to dial out or failing to connect. Not a problem, i'll turn on Wi-Fi calling, right? Wrong, option isn't available, some detail: I'm in the US on T-Mobile, updated to the latest Pie OS update, i'm very tech-capable and used to do tier 2 tech support for Verizon. Long story short, I've tried everything in the book including FDR and fresh setup as well as clearing system cache etc. and it's looking like the ONLY solution to get Wi-Fi calling (and subsequently VoLTE that i didn't realize wasn't enabled until researching and checking myself) enabled is to flash the ROM with a T-Mobile OS. Unfortunately i'm coming up negative trying to find the firmware for this phone. Plenty of resources out there for the SM-965U(Snapdragon), but none for the SM-965F(Exynos) as of yet as far as i can tell (and before any ignorance jumps in here as i've seen on other threads, NO the SM-965U software will NOT work on this model phone as it runs a different processor, non-Snapdragon Exynos chipset)
So, that all being said, is anyone out there working on a fix for this, is it likely i'll ever get a fix for this, and/or is the fix already available and I've just completely missed it? Any information or help would be greatly appreciated. Thank you for your time and consideration.

So recently i bought this international unlocked Galaxy S9+ (SM-965F/DS Exynos processor) off Amazon and it's great, everything is fine with the one major exception being that at home my signal is pretty poor and i get extremely delayed text messages coming in and calls taking forever to dial out or failing to connect. Not a problem, i'll turn on Wi-Fi calling, right? Wrong, option isn't available, some detail: I'm in the US on T-Mobile, updated to the latest Pie OS update, i'm very tech-capable and used to do tier 2 tech support for Verizon. Long story short, I've tried everything in the book including FDR and fresh setup as well as clearing system cache etc. and it's looking like the ONLY solution to get Wi-Fi calling (and subsequently VoLTE that i didn't realize wasn't enabled until researching and checking myself) enabled is to flash the ROM with a T-Mobile OS. Unfortunately i'm coming up negative trying to find the firmware for this phone. Plenty of resources out there for the SM-965U(Snapdragon), but none for the SM-965F(Exynos) as of yet as far as i can tell (and before any ignorance jumps in here as i've seen on other threads, NO the SM-965U software will NOT work on this model phone as it runs a different processor, non-Snapdragon Exynos chipset)
So, that all being said, is anyone out there working on a fix for this, is it likely i'll ever get a fix for this, and/or is the fix already available and I've just completely missed it? Any information or help would be greatly appreciated. Thank you for your time and consideration.

I'm currently researching the very same issue... So far i hypothesize , with no knowledge, that if it is rooted, you can then change the csc settings and configure it for TMO, thus enabling WiFi calling. If someone can confirm, that'd be great, otherwise i'm trudging slowly to verify.
Root and use tekhd detonator.

Well i looked at this and it looks like a non-stock rom i'm sure wrought with problems that unfortunately is not helpful. My goal here is to have my phone work and continue to get standard updates with original and licensed (more or less) software and have it actually work. I'm not interested in a full OS replacement pre-loaded with a bunch of adblockers and other crap the designer thought would be useful, just want my standard features enabled and nothing else to change if at all possible. Also, if you believe my statement here is in error please explain, your one line really isn't very helpful, and nowhere on their website is there any description as to what tekhd detonator does / is supposed to do / what it will break. I'm certainly not risking bricking my phone when their own website says under all of its S9+ related material that it's for Snapdragon which the variant i have again doesn't use Snapdragon.

This is going to be a hassle trust me. even with the Snapdragon models from different CSCs VoLTE and Wifi Calling do not carry over. An ATT 965U would have to be reflashed with the TMobile CSC and USERDATA files to get access to TMobile features. U are trying to do this with an Exynos model. I think you would have to root and install a custom firmware that has the TMobile USERDATA embedded.
Good luck.
can the U1 be flashed to the verizon u firmware? i thought i read someone tried this, but suspected it didn't work because he had previously used the phone with verizon with the unlocked firmware...

You can flash the G965U onto the G965U1 and vice versa. It's been well documented that this will let us go from one carrier firmware to another as well as let us have the unbranded carrier firmware. The only catch to this is the bootloader version of the firmware your wanting to flash. The firmware one wishes to flash must have a bootloader version equal too (or greater then) what is currently on the phone.
If your trying to ask about flashing the U1 onto an exynos variant then the answer is definitely no. You can't flash firmware from a different model onto a different model.
