WiFi Calling - Huawei Mate 9 Questions & Answers

Hi Folks
I've had my Mate 9 for around three weeks. I bought it SIM-free and I'm on '3' for my phone contract. I read recently on the '3' website that *some* Phones on '3' support WiFi calling but the Mate9 wasN'T on th elist. Yesyerday, flicking through a computer magazine, I read that '3' was rolling out voLTE on some of its phones - again no mention of whether that included the Mate 9.
So, 2 questions from a Mate 9 nooby...
1. Is voLTE the same as 'WiFi calling'?
2. I took a screen shot of my phone settings screen (attached), which now seems to have a new option relating to voLTE (I'm sure it wasn't there when I first bought the phone) - and it seems to be switched ON Before I get too excited, does this mean that I have WiFi calling?
Cheers guys!

I don't have that option. What's your firmware version?

Where do I find this information? and I'll let you know

If this number is the firmware version, mine is MHA-L29C432B138

unfortunately, nothing to do with WiFi calling...
volTE means voice over LTE....should offer HD calling while LTE/4G is available

Hi flyingjack. Thanks for clarifying. So it just means 'clearer calls if 4g is available'?

jep! but depending on 4G/LTE availability....

Fab! Every day I learn something new! Thanks for your help.
Steve

Mine is on MHA-L29C636B138 and I don't have VoLTE option....

I guess it might depend on the Carrier (just a guess, I'm no expert!)

It depends on the operator. If VoLTE is available you'll see an 'HD' icon at the top.

Hi, as my volte was still not working, i flashed the below attached zip of /cust uploaded by xda senior member ajs. It flashed properly but still no volte. So i extracted the below zip and copied cust folder and placed it in twrp backup folder as the method of oeminfo and tried to restore it but inside cust folder twrp is showing no partition to select for restore. Any solution?

Stock firmware for Huawei E5776

Hi
Does anyone have stock firmware for Huawei E5776 in English please.
My E5776 was showing NO SERVICE after unlocking from EE no matter which SIM I used so I updated it to a newer firmware version but that turned out to be some Russian network's firmware and moreover its in Russian language.
Is there anyway that I can revert back to the old EE firmware in English or update it to stock firmware if available.
Thanks

I have the same request.
I buyed my Huawei to ebay from UK but unfortually the modem wasn't a stock firmware but EE mobile firmware.
My modem is unsimlocked but I need stock firmware also because the modem is in roaming because I use it in France with Bouygues Telecom operator.
I use correct APN but WAN refuse to connect...

Got the same one with EE firmware, it reports that it's in roaming, but after setting up APN and connecting manually (or marking the connect in roaming checkbox) it works fine.
But I'm also interested in getting the stock (or other than EE and english) firmware.
Someone tried german updater?

Found stock firmware/dashboard for my E5776 from ee.co.uk!
And it's working fine - here's a screenshot which proves that:

It's on german huawei site: http://huaweidevices.de/e5776?show=downloads but it's multi-language!
There's also pdf with instructions - first need to install the Update_UT* (drivers) and then the e5776_Update*.

firmware / version
hi
is this firmware compatible with all versions of e5776? mine is e5776s-32...
really hope so
Yes, it is
Hi,
Yes, I have just updated mine which was an EE branded, all is well happily connected to three using the stock firmware.
If yours is an EE one too then don't forget to get the firmware update password from that site in the post mentioned earlier.

what's EE? an network? i'm from Portugal... and mine is from a different network... 'll it work?
Likely to work
Yes, it is likely to work.
EE is a network in the UK.
The stock firmware is coming form the German Huawei site.
It did work for my device, at any rate, there are no guarantees.

Update and lose 4G
I recently followed the instructions on installing the stock firmware on my OPTUS 4G E5776. All seemed right, I had the Huawei dashboard, but after doing this, all I can connect to is to the 3G network. It seems that if you use the stock firmware, you will lose the ability to connect to the 4G network. Has anyone else had this problem? Is there a way to set is so you can still get 4G? I have searched high and low and could not find anywhere to download and reinstall the OPTUS firmware again so I just returned it to where I purchased it from for a replacement. I am not game enough to do this again until I know I can get 4G, as this is the reason I purchased the 4G modem in the first place for better and faster speeds.
Thanks
4G Connection
@Brad1982
Someone who followed the instructions on my website to update the firmware just got in contact with me today with exactly the same issue (on the UK EE network).
To restore 4G connection go to the connection settings page and switch from Auto to 4G only and save setting. The modem will now connect correctly. Once connected for the first time you can then switch back to Auto and 4G should still work. Why this step is necessary is a bit of a mystery I'm afraid!
drops connection
I followed this thread to unlock and install the default firmware, all went ok but I find that it drops connection frequently. I change settings to 3G only and manual connect which seems to help but it still does it, any ideas?
I have seen some of the bugs mentioned here also:

How to convert stock firmware from SM-N920G to SM-N920P

I have Note 5 (SM-N920P) for Sprint, which is came with a limited set of languages,
I added more languages by modifying the language.xml but nothing happened then I realized that the whole system is stripped from all other languages,
I disabled the dm-verity as well but a red line is showing after booting (Kernel SElinux is not set to Enforcing) and the phone is stuck at Samsung logo,
What I need is to convert a stock firmware from another Note 5 with multi-languages and to disable dm-verity,
I found someone who already did it in the link below but he doesn't want to share it or sell it to anyone except repair shops,
https://www.youtube.com/watch?v=Qep7fkDq9Zk
So I chose to convert N920GUBS3BQB1 6.0.1 for SM-N920G to N920PVPS3BQB1 6.0.1 for SM-N920P as they share the same base build,
I set everything up in order to do so,
I would be grateful if someone could provide me with instructions on how to do that and I really want to learn how to do so as well,
Many thanks in advance
Update
After downloading the full firmware for SM-N920P and SM-N920G,
I extracted SM-N920P and replaced the boot.img with a modified one that has dm-verity disabled (for that I chose Aurora kernel), cache.img and the system.img for SM-N920G,
I repacked the firmware using cityradar's tool (Thanks to him you can find in the link https://forum.xda-developers.com/s6-edge-plus/general/tool-tools-file-extraction-img-tar-md5-t3236605 ),
I flashed it with odin and the phone booted successfully and everything is working fine except there is no baseband,
Then I replaced the modem for SM-N920P with the one for SM-N920G and re-flashed but it failed because the security check for the radio file,
Now the only thing remains is how to disable the secure download in download mode or to modified the modem.bin and make it bypass the security check,
I would appreciate if someone could help with this matter,
I will be awaiting for your replies
try reflashing the modem.bin for the n920p

Thank you for the reply,
I already did that from the start that's why there is no baseband,
If you check the youtube link in the first post you will see that the guy flashed the modem for the SM-N920C into SM-N920P,
So we need to modify the modem.bin to bypass the security check
Let's proceed to plan B as I feel that the expert in xda are not here anymore,
Let's port the firmware (app, priv-app and everything related to them only) from SM-N920G to SM-N920P,
Everything is set up with the latest tools from xda (deodexing, modifying and repacking) in both Windows and Linux,
I searched the forum but I couldn't find a thread about porting from-to the same model,
I would be grateful if someone could advise me on how to do that,
Your replies are appreciated
aren't bin files just containers? have you tried extracting the files from the modem.bin? and opening some of the contents in a text editor?
did u accomplish i had tried too i was falied !!!!!!!!!
I have sprint N920P. But there are some problems,
1. no hotspot available
2. some network activation crap when turn on phone
I want to convert it to N920G. How can I do that ? (If possible).
I have another question, If I do something wrong and at the end, flash N920P stock rom, will my phone carrier locked? I don't know how this network unlocking works. Is it on device software or on network side. ?
Thanks
I have file to change the model from n920p to n920c.
I have file and tutorial.
I bought Note 5(n920P) from Honk Kong and I couldn't use it in UK.
I paid for this file and now I have in phone description n920C, no sprint activation, active hotspot and what was most important for me 4G network.
If you are interested write me please.

Sony XZ Premium fingerprint enable? Help

I am getting my Sony "U.S" Version just because of its warranty, is there a way i can Enable the fingerprint. Please help
currently all you could do is flash the International firmware. I haven't really looked into anything though personally. I'm not sure how they disabled it, maybe changing a 0 to 1 somewhere but I doubt it.
Yes I got the US version from Amazon and just flashed the CE1 firmware and fingerprint works after flashing that firmware

Buy it from the UK. Same warranty. No need to flash anything. Save about $100.00

It doesn't have US warranty, probably you have to send it back to UK. Personally I don't care about warranties, never had to use for any of my many phones until now partly because don't keep the phone that long. The other advantage buying from Amazon US is ease of return in case you don't like the phone. If you played with it before and 100% sure you like the phone and will definitely keeping it, then yeah better to buy from clove and save the extra $150 or change.

I used the newflasher tool in the below link. Personally this is my first Xperia device in a long time and haven't used the Xperia flashing tools before.
https://forum.xda-developers.com/showthread.php?t=3619426
1. Make sure you have the right drivers installed. I installed Xperia companion tool since someone mentioned that should install all the drivers. I also installed the flash tool and fastboot drivers from Xperia flash tool since I had issues putting my phone in flash mode. If you are using Windows 10 you have disable verify driver signing in boot before installing the flash tool drivers.
2. Download the firmware of your choice, I chose CE1 (Central Europe) firmware over other Asian firmware.
3. Then follow the instructions in the thread to flash.
Main issue I had was putting my phone in flash mode. But apparently flash mode doesn't have any screen like recovery etc. You just have to turn off your phone then while holding the volume button down connect your phone via USB. That should put in flash mode even though you don't get any screen to say it's in flash mode.
Once I put in flash mode everything went fine by following instructions in the thread.
Thanks,
So when you downloaded the files with XperiFirm and used NewFlasher did you delete any of the files or just drop newflasher into the created directory and flashed everything.

Just dropped all newflasher files into the created firmware directory and just ran the newflasher application from that directory. It flashed everything in there.
I know the thread says if you want you can remove specific things from the firmware directory if you don't want to flash certain things. But I didn't see any reason to do that and I never care about wiping my device since all my info is backed up in the cloud and takes around 30 minutes to restore and be up and running again. Just to be safe I flashed everything so that it doesn't screw up anything. I haven't used the Xperia flash tools before so kept it simple.

I'm pretty sure it's the US model because the fingerprint sensor is disable.
there is no VOLTE on this phone, no menu options for advanced calling like wifi calling either.

Must be an Branding/Software issue i guess.
On the unbranded EU version, both is available.
wifi calling: Settings -> Wireless&Networks -> Wi-Fi Calling
VoLTE: Settings -> Wireless&Networks -> Mobile Networks -> Enable VoLTE

Are you sure it has nothing to do with your service provider?
I bought mine from the UK (not sure if it is the same as the unbranded EU version you mention) and when I look for those same settings they do not exist.

Could be that the settings are not available unless your carrier/plan supports them. Pretty sure anyone slipping a T Mobile sim in has those services.

Get VoLTE working on H8314/H8324 XZ2 Compact in India on Airtel and Jio

I spent quite a bit of time figuring out how to make the VoLTE work on Airtel and Jio in India on a USA edition H8314 phone.
Sony for some reason doesn't bundle all operators VoLTE configuration in all images, not sure why, typically not the case with other high end phones. And they have region specific bundles or OEM customization.
I solved the problem by taking parts of the regular dual sim ZX2 firmware H8296_Customized IN_1314-9934_52.0.A.3.202_R4B, which has the VoLTE configuration for Airtel and Reliance, and flashing it on my phone. VoLTE works! No issues noticed so far (will update if I notice anything).
Here are the steps:
1. Install XperiFirm
2. download the Indian version of firmware for XZ2 dual, in my case H8296_Customized IN_1314-9934_52.0.A.3.202_R4B
3. download and install newflasher
4. From the downloaded and extracted set of files in XperiFirm download directory, copy the following to another directory
oem_other_X-FLASH-CUST-B6B5.sin
oem_X-FLASH-CUST-B6B5.sin
5. Copy the newflasher also to the same directory, now this directory should have 3 files
6. turn off the phone,
8. enter flashmode (vol down + connect USB cable to PC)
9. run the newflasher, in the directory you prepaired in step 4 and 5
10. Unplug from USB after the flashing is done and restart your phone, it should work with VoLTE on airtel as well as Jio. On airtel it may take a few minutes before the calls actually start going on VoLTE but it works perfectly fine.​
This doesn't require bootloader unlock so all phone function would remain good. Feel Free to ask questions, the version of firmware on my XZ2C is 52.0.A.3.163 USA generic.
So this works good with Indian and US networks ?

6. turn off the phone,
8. enter flashmode (vol down + connect USB cable to PC)
9. run the newflasher, in the directory you prepaired in step 4 and 5
10. Unplug from USB after the flashing is done and restart your phone, it should work with VoLTE on airtel as well as Jio. On airtel it may take a few minutes before the calls actually start going on VoLTE but it works perfectly fine.​
This doesn't require bootloader unlock so all phone function would remain good. Feel Free to ask questions, the version of firmware on my XZ2C is 52.0.A.3.163 USA generic.

I haven't traveled to USA since, but I do not see why it won't work.
thanks ahzam for sharing this. My XZ2 is on Customized Version CE1 and VoLTE didn't work with o2 Germany. I downloaded the DE firmware with xperifirm and flashed the 2 files you mentioned via newflasher v13. Reboot and everything is working fine now!
Thanks again,

Hi ahzam,
I have bought H8296 unlocked international version from USA.
I am also not able to use the VoLTE in India on airtel idea or jio.
Will this firmware help me to get the VoLTE.
After doing so, will I be getting future official Sony updates or it will be rooted device and Xperia support will end?
Can you please help?
Regards
Akhilesh

For me updates still work.
Your device will not be rooted after that. So in my opinion you will not loose your warranty.
Greetz
Thank you for confirming
I will try this and keep you posted if this works
Thank you Guys
It worked and now I get VoLTE on both Airtel and Jio.
However for Airtel it takes some extra 10 seconds to get VoLTE.
One problem I have noticed after this. I received an official xperia update but got an error "Could not Install" while installing this update.
Do you know how to resolve this issue?

For me all updates worked so far without any error. I think i've read somewhere, that the update can be done via Sony companion. (But for me companion never worked in any way^^)

I spent quite a bit of time figuring out how to make the VoLTE work on Airtel and Jio in India on a USA edition H8314 phone.
Sony for some reason doesn't bundle all operators VoLTE configuration in all images, not sure why, typically not the case with other high end phones. And they have region specific bundles or OEM customization.
I solved the problem by taking parts of the regular dual sim ZX2 firmware H8296_Customized IN_1314-9934_52.0.A.3.202_R4B, which has the VoLTE configuration for Airtel and Reliance, and flashing it on my phone. VoLTE works! No issues noticed so far (will update if I notice anything).
Here are the steps:
1. Install XperiFirm
2. download the Indian version of firmware for XZ2 dual, in my case H8296_Customized IN_1314-9934_52.0.A.3.202_R4B
3. download and install newflasher
4. From the downloaded and extracted set of files in XperiFirm download directory, copy the following to another directory
oem_other_X-FLASH-CUST-B6B5.sin
oem_X-FLASH-CUST-B6B5.sin
5. Copy the newflasher also to the same directory, now this directory should have 3 files
6. turn off the phone,
8. enter flashmode (vol down + connect USB cable to PC)
9. run the newflasher, in the directory you prepaired in step 4 and 5
10. Unplug from USB after the flashing is done and restart your phone, it should work with VoLTE on airtel as well as Jio. On airtel it may take a few minutes before the calls actually start going on VoLTE but it works perfectly fine.
This doesn't require bootloader unlock so all phone function would remain good. Feel Free to ask questions, the version of firmware on my XZ2C is 52.0.A.3.163 USA generic.

you should be able to get VoLTE for any region by following this process, you need to extract the files from right version of the bundle for that region.
hi, actually I'm using xz2 premium (H8166) which isn't supported by the jio sim and airtel volte so can I try this method? Thanks.
updated : actually, it's working for xz2 premium so no problem in Volte... so rite now Im using airtel and jio both working fine... but mobile restarts for network optimization while changing mobile data from sim1 to sim2 or sim2 to sim1. Anyways thanks Alot for this awesome tip man.. I really felt bad for my xz2 premium now I'm really happy. You saved my money. Thanks again.

First of all, I would like to say Big thanks who share this Procedure, Now I am able to use Volte Functionality
Now I have the same problem while changing sim1 to sim2 to and vice versa but before did volte procedure it was working fine in both sim, so as per my opinion this problem related somewhere Volte functional
I bought this Cell from the Middle East, So in Middle east it was working fine while changing Sim1 & Sim2 Procedure and even in India it was working
So if someone does R&D than might be it is a curable issue, I don't know why Sony did a big mistake nowadays even Oops, Vivo, all Chinese implements successfully these things, even sony dosnt implement Auto Hide status bar in Compact Series Cell

Today I discovered 3 more problems
1)After Install Volte Firmware, Because in India no Official launched XZ2C , after install we can not get Firmware Update
2)If you Switch Mobile data between two sims, Cell will restart automatically
3)In Setting->Display you can not get Super Vivid Mode or Professional Mode for better color reproduction
So if anyone tells me XZ2C officially launched which country with Volte Function, if we get an answer than we can solve all the issue
Fact. reset

To get back this, just factory re-set and will get this options. Anyway It is not working any VoLTE (it's just showing the LTE symbol and option in seeting, in reality your call is routed on 3g/2g. ) you can verify this by selecting 4g only and try calling.

VoLTE T-Mobile USA Working on H8324 Xperia XZ2 Compact Dual Stock

I managed to get VoLTE working on the xz2cd (H8324) with T-Mobile USA using the xz3 (H8416) USA firmware oem-*.sin files.
Thank you to all the others that figured out the process details so all I had to do was try every combination - see the other VoLTE threads in this forum to guide you on the actual steps. Also thanks to Androxyde and Igoreisberg for the flash & download tools!
I have this working with the H8324_Customized NOBA_1313-6167_52.0.A.8.25_R5B firmware, I happen to choose, replacing only the oem-*.sin files from the XZ3 H8416_Customized US_1316-4522_52.0.A.8.25_R10B firmware. When you set both lines to "LTE (preferred)" and you'll be able to make LTE calls on both lines, however it may only show [HD] calling on the line you configured last I think but it'll be VoLTE on both.
Enjoy and thanks again to all the other threads that guided me through this long but worthwhile trial process. I wish the carriers didn't make LTE VoLTE provisioning difficult, why didn't they just make it universal like 3G.
Note: I was able to separately get Wifi-Calling to appear using the H8276_Freedom CA_1313-8876_52.0.A.8.25_R3B oem-*.sin files but it wasn't functional on T-Mobile USA - I think someone with a little bit more knowledge might be able to get this to work, unless you can point me in the right direction.
Someone please make an open firmware thin/light/compact dual SIM phone with Wifi-Calling/VoLTE (removable battery a bonus)!
Do you think the files would be the same on the H8314 US edition? i'm assuming you need to be rooted for this to work?
Hey Mike, Can you please share(download link) OEM*.sin files of USA firmware for Volte Settings
Im wondering if we can flash the OEM files from the US XZ1 Compact to get T-Mobile VOLTE and Wifi calling? I would try it myself but I cant find one of these phones at a reasonable price. If I do I will try and report back if anyone cares. I am glad at least VOLTE seems to work with this workaround.
VoLTE provisioned on XZ2 but calls are still made over 3G
I’ve done the same for my XZ2 (not compact, H8266). The VoLTE button is now active, but calls are still making over 3G. Any suggestion?
I just talked to a T-mobile specialist, and he confirmed that my phone should work and no need to register or do anything if it supports all bands!!! As he told me "only check for compatibility" and mine is compatible! ?
Were you ever able to get this working? New XZ2 owner and of course I bought this within a week is the announcement about all non VoLTE devices being kicked off in January..
Is there anyway to get volte working for tmobile on the h8314?
XZ2C H8314 VoLTE working on T-Mobile USA

Yes VoLTE works but no VoWIFI with the following method:
Download USA Customized for XZ2C (H8314) and use only the two oem...sin files from XZ3 (H8416) USA Customized. (overwrite the two files in the XZ2C stack)
Use newflasher tool. (I deleted all .ta files and userdata file to avoid losing existing data)
To put the phone into flash mode, power off, hold the vol down button and plug in your usb cable while holding the button until you get a dim green light.
The device will show up in device manager under USB and you can run newflasher as administrator. Please search for a tutorial - there are many that are very good with screenshots of the files you want to move into the newflasher folder.
Some hangups I ran into when setting up and flashing -
Installing flashtool drivers required disabling driver signature enforcement on win10 (Flash device did not show up in usb in device manager until this was done)
For safety, after the flashtool driver install, I performed a repair on xperia companion app in case of any driver conflicts.
Running newflasher again, I got an error: Unable to open ./boot/Apollo_XBootConfig_MiscTA.ta! after multiple system files had been flashed.
But not to worry, the command window said the phone exited flash mode, but got error 933 - unable to sync. - No worries though, just make sure the command window states the phone is out of flash mode somewhere, disconnect your cable and power up your phone.
Then you will get an android message saying your carrier settings will update after reboot and the phone may reboot.
Once rebooted, enter *#*#4636#*#* in your phone dialer app (Takes 30 seconds after fresh boot for the menu to come up) , select phone information, and select LTE only (Note: VoLTE Provisioned will have the slider set to the right, but grayed out - Before the re-flash, the slider was set to the left and grayed out), reboot again. (If you click the 3 dots and look at IMS Status, you will see IMS status Registered, VoLTE Available and UT interface Available - Before the re-flash status was not registered and not available)
Now when you make a call, it will say "HD" in your dialer while on a call and your signal indicator will no longer say 3G when calling.
VoWIFI does not work, but you can use whatapp or something else like googleFi if its a must have, but in my case, I did not want to have to buy a new phone in January when they turn off 3G - Phones are too darn big now anyways and I love the display on this phone.
Notices will go out starting AUG 4th if your phone is marked as not supported using T-Mobile IMEI BYOD online tool - Their tool said my phone does not support VoLTE (Not fully true - It just does not have Band 71 for Long Range VoLTE but will use Band 4(66) just fine, I cannot confirm band 12 even though the phone spec supports it. It appears only Short range VoLTE is working on the phone unless someone else can confirm with this method, My Band 12 tower is behind a hill and i am 20 miles from it) T-mobile currently does not have a whitelist like AT&T, so If the UE (User Equipment - ie. phone) is configured properly, the network will handle the rest. I hope this practice does not change.
The advantage to using this method, is you are using completely stock USA files - My bootloader is locked and i am not rooted BTW. My XZ2C is only carrier unlocked.
The build number of both Roms I used was the same 52.1.A.3.49 XXX - Good Luck.
BTW - Some people were asking what modem config is working with VoLTE on T-mobile USA - to get the modem setting type *#*#7378423#*#* and in the service menu select software info, under Current modem config the value reads:
row/tmobile/vl/us

You will need to try this. I was not so brave. The reason is the difference in the build IDs and oem.sin file names between the XZ1 (Old) and XZ2 (Current as of July USA Customized builds).
Mixing and matching files is easier when you are doing so off the same build ID. Thats why V0LTE worked on my XZ2 using XZ3 oem.sin files, they were from the same build ID and had the same names even though the sizes were slightly different.
It may work if the format of the oem.sin file did not change between the XZ1 builds and XZ2 Builds. The more different the builds, the higher the risk of something going wrong.

I made the mistake of calling sony and t-mobile for support and they both kept blaming each other, the reason they don't know why VoLTE does not work on some phones is they really don't know enough about their network or the basebands in the phone or the software build process and details about android sin files - as they should not either cause if the network engineers, device manufacturers and software developers all do their job and stick to industry standard practices, it will just work anyway.

Search for flashtool on XDA there should be links for that, but you only install the drivers from it, not the tool.
You also need the xperia companion software download from sony website for any missing drivers from flashtool.

It's been a while but wanted to thank you for taking the time to write out these steps. I finally took a shot with the incoming shutdown of 3g for my XZ2, but unfortunately it did not work. Similar to what gigili said, while VoLTE appears to be provisioned the calls are dropping to 3g/HSPA like they originally were. After setting to "LTE Preferred" and rebooting, calls would not be made at all. I also saw "Unknown" under the Modem Config, and from what you said it should reference T-Mobile after flashing the OEM sin files.
I tried this using the latest firmware available on XperiFirm for the XZ2 (Customized US H8266 - my device is H8276) and the XZ3, which I used to grab the two OEM sin files. The firmware is 52.1.A.3.137.
Using UnSin, I unpacked both "oem_X-FLASH-CUST-B6B5.sin" files in both firmwares, and under modem-config there are a bunch of folders, and each one seems to have a conf files pointing to "mcfg_sw/generic/row/tmobile/vl/us/mcfg_sw.mbn."
I read in another thread that T-Mobile maybe has some way of blocking this workaround now, but I'm not entirely sure if that is true? Totally understand if you've moved on from the device as it's been a while, but am admittedly curious if there's a specific firmware version that this works on I could try to salvage the device.

I am working to bring support for T-Mobile VoLTE on the xz2c to LineageOS 18.1. As of this writing, official LineageOS builds for this device do not support VoLTE unless it was already enabled and working in the stock firmware.
I have submitted some patches which may resolve the issue for TMO and probably other carriers as well. They work for me, but testing has been limited. If you are interested in using LineageOS instead of the stock ROM, and you are willing and able to build LOS yourself on linux, consider giving my patchset a try. Please read the patch description fully before attempting a build: you will need to obtain and mount some additional files first. The LineageOS wiki has additional instructions for creating a build environment.
EDIT: My patch is part of official LOS 18.1 starting with nightly 20220401. There is no need to build it yourself.

You are a saint for working on this. I bought a H8324 XZ2c recently and was super disappointed it didn't work, so I am back to my XZ1c. Super frustrated. If you ever get a pre-compiled ROM, I would love to try. In the meantime I will try to compile it myself in the coming days despite my technical illiteracy.
If that doesn't end up working, what stock firmware is available with T-Mobile VoLTE enabled and working, so I could step up from that to Lineage? Considering how old the other solutions for trying to get VoLTE working, I am hesitant to try any especially funny business of switching old firmware files from other phones around.

As far as I am aware there isn't any stock firmware that works "out of the box." The xz2c is listed as "unsupported" by t-mobile, which probably means there isn't any sort of stock ROM out there that works. Sometimes carriers do release "branded" ROMs, but there's nothing like that for this device AFAIK.
LinageOS is designed to be installed "on top" of an existing stock ROM. If you attempt to install it after you have flashed another distro (like an AOSP build), you will likely just make a brick. If you do end up bricking your device, do not despair. You can use Emma to restore your device to factory condition. Emma is available on the Sony Developer World website, and there are many guides available for it.
