ZTE Axon 7 VoLTE lives on Treble. Updated V2! - ZTE Axon 7 Themes, Apps, and Mods

VoLTE Mod for Axon 7 Treble!​
Hey ZTE Axon 7 Treble group,
Ok I've been working on this VoLTE for a while now on spare time. I've had multiple devs from other forums test it out on phones for their GSI. They confirmed it's working. I've also had multiple testers from the Axon 7 Trebleshoot group test it and confirm it's working. I know for sure it works on T-Mobile/T-Mobile based carriers but don't know for other carriers. Here is the modified package.
Enjoy!
Requirements
1. Phh-based GSI
2. TWRP Treble
3. System/Vendor with Decryption level support
4. Compatible carrier that supports VoLTE
5. No complaining about the process to install because trust me it was alot more work for me to modify the apks internally and put together.
Installation
1. Extract VoPackage zip.
2. Install ims.apk in the package.
3. Reboot, let it fully boot and see if you have VoLTE, if not go to next step.
4. Reboot to TWRP.
5. Mount /system and /vendor.
6. Flash VoMod zip.
7. Reboot and check your ims registration by dialing *#*#4636#*#* and going to the 3 dots in the top right corner to check IMS Service Status. It should say registered.
Update V2
Do the same installation of Version 1.
Added Ims Settings to /system/app for improved stability.
Support
@phhusson for his great work in treble development.
@raystef66 for file structure implementation.
Special thanks to also the Axon7 (s)GSI Trebleshoot Testers!

Thanks for all your support along the way! Appreciate it bud.

AFAIK in Poland, if GSM provider (in my case Orange PL) doesn't enable VoLTE for a specific model of the phone this functionality doesn't work (I still get unregistered in IMS). So for me, it doesn't work, but still thx for the effort.
I've changed the automatic (PRL) setting in IMS, because I got no mobile data, to LTE only and I got VoLTE icon and in IMS it says 'registered" so maybe it really works. THX again.

Anyone tried this on los 15.1 unofficial?

Nope, phone process goes in crash.
But it works well in Bliss ROM pie.
Sent from my [device_name] using XDA-Developers Legacy app

Ill be testing this on verizon. Currently on RR6 with VOLTE working great but RR6 has not had an update in over a year so I'm jumping to pie GSI in hopes I can get VOLTE working.. Ill post back about my results.. THANKS

After every reboot I get asked to set up my SIM card. Is there a fix for that?

I wanted to report back on the SUCCESS with this patch on GSI OMNI Rom. It works with VERIZON MVNO. I was able to turn on VOLTE inside the phone information testing screen and be connected to LTE towers for voice and then make an HD voice call with no issues. So yes VOLTE has truely returned for PIE GSI.

Working using Liquid Remix, Verizon.
I have to disable and re-enable roaming and data every so often.
Preferred Network Type should be on LTE/CDMA not Global in both Phone Info(*#*#4636#*#*) and under Mobile Network -> Network Type
All the patches stick, it's the phone radio option that doesn't stick on some reboots.
There are other radio types that show registered, but don't allow for sending MMS.
Thanks @kountry83 HD voice sounds so great.

Just noticed my MMS doesn't work while this is installed.

With VoLTE activated using patch and LTE enabled in IMS I can call other phones, but when others are calling me they get only information about my phone being busy at the moment.

Mine works fine. Maybe a clean flash will work and make sure your APN has the MMS in it.

Clean flash and make sure system and vendor mounted.

Ive been using this VOLTE fix with verizon MVNO redpocket and discovered some helpful hints I want to share with anyone having issues. These tips only apply to verizon but may work on tmobile or at&t.
1. In the phone info screen *#*#4636#*#* in the 3 dot menu there is an option for select radio band, toggling this between some of the other options seems to help voice get on LTE. With verizon it seems that swapping radio band to a CDMA only option cellular 800 may get you back on and then you can swap back to US or leave it alone.
2. Check IMS registration under the 3 dot menu and confirm that you are registered, if you see unregistered check to confirm the IMS.apk is installed, if you see registered but cant make calls but can text then go back and toggle the radio band till you get both.
3. the preferred network type also seems to matter but not as much as the radio band. Of course if you have this set to something that is not available to you it wont work at all, for example verizon requires LTE/CDMA or LTE/CDMA/UMTS auto (PRL) there are some others that work but the auto (PRL) types work the best. So make sure this is set correctly for your provider.
4. Make sure your settings under mobile network are also setup, like enhanced 4G LTE mode is switched on, preferred network type matches the same you picked for phone info screen etc etc.
After the following are correct you should be ok, if you have any other issues I suggest reflashing the volte zip or reinstalling the ims.apk. Ive also had to reflash my rom and gapps which also helped but is a pain in the butt.

Follow up..
HRM over on telegram gave me an awesome piece of information about how to fix the issues with your VOLTE package, specifically IMS registration in PIE that come up randomly or by doing things like sim swaps. I know Kountry83 is working on fixing these issues. But if you need LTE back and are frustrated and did one of the following this will help.
1. sim swap,
2. loss of LTE for extended period of time & IMS wont re-register.
This is what you have to do. Reflash vendor and kernel and then reflash modem. After I did the final step to reflash the modem is kicked in and fixed all the IMS issues. It seems that perhaps vendor gets corrupted or stuck maybe modem or both do. re-flashing kernel is needed if vendor is re-flashed it seems. in any case i am super happy to know there is a fix when you do a sim swap. These issues seem to affect verizon users more then tmoble or at&t. In the past I thought flashing just the modem would work but it was not consistent
.

Any updates on this since last july?

Not sure if anyone's still using an Axon 7 but this still works! I was able to activate VoLTE on my Chinese Treble Axon 7 on H2O (AT&T). Took me a moment to meet all the requirements but installation was pretty straight forward after that. Many thanks!

VoWifi (AOSPEx) on Le Max 2 (x829)?

So, my carrier suggests for themselves it's a proprietary solution they bake into their phone roms, and may well be. However, they've recently liberalized registration for this service which suggests they may be implementing broader access for devices.
Anyhow, I was just wondering - if we are to operate under the assumption that wifi calling works on my carrier and compatibility doesn't get in the way.... how would I actually activate it and verify that it is active? Ideally on this ROM, but if it's not too deviant, any process would be appreciated.
Thank you for any assistance.
I am using official RR oreo and wifi calling works perfectly fine with my carrier.
Heyyo! Your best option for testing it is to try out AEX or Pixel Experience as ShivaTehaPeddi is the guru of VoLTE, VoWifi and ViLTE and such. :good:
I'm unsure if he has the latest Canadian APN settings but my unofficial LineageOS 15.1 builds do include them.
I'm with Fido and when I tried it with Koodo Mobile both carriers I get IMS registration failed.
To check this? Enable VoLTE and VoWifi in your settings under mobile data.
Then go I to your dialer app and dial...
*#*#4636#*#*
It sometimes takes a few minutes to open if your phone is freshly booted.
Then in the menu select IMS status and hope for the best.

With respect, that addressed literally nothing I asked.
I'm not on your carrier. I'm not asking if voWifi works generally. Etc. etc.

Sorry to only address this now, but I tried that and I just get a robot saying (with a seemingly Chinese accent, no idea if that's related or not): "Please enter 6 digit password for ... ip something .. account then press pound."
Any thoughts?

Umidigi F1 and GSIs: Getting them to work with Verizon

Good day all,
I'm encountering an issue: a fairly new phone of mine (Umidigi F1) loses its ability to get data from Verizon Wireless when I install Treble Generic System Images (AOSP-based, typically derived from phhusson's et al work). For clarification, despite being from a small Chinese company, the phone normally fully supports VZW (4G LTE data, calls, and text). While on those GSIs, I get a signal and am able to call people with it, but there is no data from the connection.
The APN settings appear to match the ones that work normally (stock F1 and a Pixel 2), so despite not being able to edit or add a new one, I am led to believe this isn't the culprit. Next, I looked at build.prop; the model, device, and brand info changed from the default states and I believe that VZW may be strict enough not to allow the altered info on their network. Attempting to modify build.prop causes a boot loop, though.
Anybody have any thoughts on what I can do? One of the comments at the top of the build.prop file indicates that it is autogenerated by buildinfo.sh. Should I attempt to modify that instead? Or maybe something else?

many MTK soc devices on pis gsi have this issue with sim based data connection. Some even have issue with sms / text.
I did at one point have data working on one of my mtk phones, only when switched connection typs to 3G. But that was not acceptable because way too slow speeds. A solution may come. but i do not know when.
umidigi-f1-tag
I just got a umidigi f1 and am trying to get it working on Verizon. I have talk ant text(sms and mms) working through sim1. However, like you I can't get data to work.
The odd thing is that I can't seem edit the apn settings. That section is missing from my mobile networks section. I am on a stock rom, not rooted.
The sim I was using is a page plus sim. It gets service though Verizon via Tracphone.
I think my issue is that my apn is not set correctly.
Success!
Go to the phone dialer and dial
*#*#4636#*#*
Go to phone information and change your preferred network type to lte only
The default is lte/umts which probably just good for GSM phones
You should see a lte connect. Hit the ping test to verify if you can ping Google.com
Edited to say, the phone is kind of flaky with regards to the APN setting so ymmv. It was working for me for a while then stopped...
Edited 2: Okay I figured it out. To reveal the Apn menu on Verizon, change the preferred network to LTE only as above, then unselect 4g in the Mobile Network section for the Verizon Sim. Restart the phone. Next time you go to the Verizon section, there should be an Apn setting item. Create the proper Apn for Verizon because the default probably does not work. For me, I needed tracfone.vzwentp.
Here's the phone info screen
Here's the mobile network section for the Verizon Sim. Nonintuituve but had to disable 4g toggle but doesn't have any effect on speed. After a reboot, Apn section shows up
Hellom did you get it to work on Verizon? If so what are the full steps?
Make sure your Verizon sim card is in slot 1. Sadly, it seems like Verizon works best in that slot so not able to use a micro SD card.
On 2 other phones running on Red Pocket Verizon, everything just worked. No need to do anything extra.
Also disable wifi calling.
On my other phone running on tracfone/page plus, I had to do the extra steps in the previous posts above.

Wifi Calling and 5G doesnt work, can we somehow hack this?

Hey guys,
neither my Wifi Calling, nor 5G doesnt work on my Redmi K30 Ultra. Not sure whats the deal behind it, maybe its the Mediatek chip or that it doesn't pass Safety Net or that its not made for Europe.
Anyway: Can we hack this somewhere? Maybe modify some props or something and magically make it work?
Thanks so much! <3
More info: I've done the usual stuff like activating Wifi calling, VoLTE and 5G in settings and also disabled carrier check via number code. I also tried all 3 big carriers in germany
Telefonica/O2: Nothing works
Vodafone: LTE "works", it shows an HD icon at the top but Wifi Calling doesnt work and 5G doesnt either. Shows both VoLTE and Wifi Calling as enabled in Phone Info.
Telecom: Nothing works, but it shows in Phone Info that VoLTE and Wifi Calling is enabled.
@Mirardt
Per description the phone supports Wi-Fi calling, VoLTE and LTE, so I think it's not a chipset problem. Carriers will typically sell these data services with smartphones as part of a bundle.
I guess it is a problem with carrier ( data plan chosen ). You can try to contact your carrier and check if everything is correct from there end.
In no case your issue has something to do with SafetyNet API what is an anti-abuse API application developers can implement.

Hey there, yes everything is activated from the side of my carrier and also i spoke with vodafone technical support and they activated everything they could, reset the network etc.
Also both VoLTE and Wifi Calling work on the iPhone with all of the cards. So it has to be something on the phone.

Thank you for helping! @jwoegerbauer
Update: I have confirmation from german review website that both VoLTE and Wifi Calling worked for them on the K30 Ultra. Maybe that helps in identifying the problem?

Sometimes they just block per device model (supporting only phones that were certified for their network) and you need to convince them to let you in
Or, you could (again) play with props like ro.product.manufacturer and ro.product.model to pretend you have some fancy Samsung - bcs if it shows enabled in the settings, it's likely blocked at the time of handshaking and negotiating to use the service
It's also possible to capture the UE Capabilites offer (see attachement for my LTE part) and response - I will try to find where was the URL with know-how and instructions

I talked to a vodafone technical support guy and he said that everything is fine and open from their side. Also my phone runs with your fingerprints (Mi9T) for a week or so and it didnt change anything.
Do I understand it correctly, that all the methods you linked there only work with Qualcomm chips? Cause the K30 Ultra does have a Mediatek chip. :cyclops:

If the doc is only about Qualcomm, you will need to Google for e.g. MTK bands UE Capabilities
But MTK was usually more open, people were even able to easily change IMEIs.
There used to be a code for MTK Engineering mode, with options to enable bands and so

Ok do I understand correctly that UE Capabilities are parameters that my devices has that sends information if it can do 5G or VoWifi and so on?
After a bunch of Apps that refused to work with my phone (unknown device not supported) I did found one that looks promising. The problem is that I have only littly orientation and understanding. Can you see what setting might be relevent and maybe if we can get those UE Capabilities changed inside the app?
What I tried is switching the "Entitlement Status" of Wifi Calling on "Enable" (It was disabled as I opened the app), but nothing changed. The Entitlement server is left blank, maybe that could help?
Also I just swapped every possible thing from "false" to "true" inside ePDG Config, but it didnt help so I reseted it.
If you (or anybody else) could have a look and give me some direction I would grind it out myself!
edit: Upload doesn't work on this forum somehow, strange. Here is the Gdrive link.
Ok I just looked through every single option their is, screenshoting everything that seemed relevent.
There is band information that seems like it is what you mentioned and it is editable! @zgfg
Also a couple of other direct mentions of VoLTE, like props in IMS settings.

Very interesting, (as expected) you can control many things on MTK ( too many)
For LTE bands, I think you need bands 1,3,7,20 and you don't need TDD bands.
For 5G, googling tells me that for Germany you need: n1,n3,n28,n78,n258.
Suggesting you to double-check for your operator and enable what's missing and reboot.
B20 might be available in a shopping center, or dense busy district
In the Call* and IMS-Registration* screensots, are all those params enabled or you need to open another screen for each (modes)?
On the IMS, I would put VoLTE to Default, not to CMW500 - seems to be a mode for testing equipment.
Also, you could try SMS over 3GPP or 3GPP2 (that means SMS over IMS but when you register to IMS), but check does it still work over cellular
Last screenshot says that it's not registered to IMS, but seems there are additional settings for IMS authentication (that's about registering to IMS - VoLTE is an IMS service)
I pretty much tried everything out you suggested and it didnt work. Thats why I waited to work on that until I freshly reset my phone with GApps Pico and I did that yesterday. During the Installation process there are 2 question came up:
1. There are Google Carrier Services I can install through play store. No clue what it is, does it matter?
2. I have found multiple interesting sounding apps in system/priv-apps like "engineermode", MtkCapCtrl", "MtkTelecom", "MtkTelephony Assist" and "MtkTeleService", the only one I can find in Apps is "engineermode" and i didn't manage to open it. I tried to install the other apks but it didnt allow it. Anything that might help us?

Tried everything but it made no difference. Also tried IMS test mode on with and without SMS.
Also it keeps saying its not registered in PhoneInformation1.
Should we try to change those numbers in the VOLTE settings to something like this?
Edit: I activated logs telephony logs and somehow got a bug report without even calling somebody. Uploaded it.

wifi calling hardly ever works on foreign phones but my k30 ultra gets 5g on tmobile in my state.
Wifi calling hardly ever works on foreign phones but i get 5g on tmobile in my state , the k30 gets 3 bands that havent been listed , just get a mtk engineering mode app to see what bands you can work with.

[Need Testers and Help] VoLTE / VoWifi carrier profiles for FX2Pro

The phone is relatively new and since it's not mainstream most carriers don't support it yet. Some people say they have VoLTE enabled and it works but I personally switched to Singapore EX and it seems VoLTE isn't detected at all so I started digging and it seems this issue is present in most Chinese phones. (https://forum.xda-developers.com/t/guide-activate-volte-and-vowifi-simple-and-clear.4116051/) In this thread they used the Qualcomm tool and exploit the bug in EngineerMode on OnePlus phones which we don't have an access to and since we can't root or unlock the bootloader we can't modify build.prop or change any system files.
-----Maybe it's my carrier, maybe it's the Singapore ROM so please if VoLTE and VoWifi works for you could you post here which country you're on, which ROM version and if you changed region before or not.------
First a warning: If you aren't tech-savvy, experiencing issues or want to potentially turn your phone in a paper weight do NOT try this at the moment. We do not have the tool to restore your phone back (wiping data might work but idk). You can send your phone to Oppo for repair but you might have to wait for a month or two.
I don't know if you need to unlock your phone from the other thread to have access to this mode(I did have it all decrypted during this test) but in addition to the *#808# engineer mode and *#*#4636#*#*(Where you can check if you have VoLTE enabled) I found we have access to *#36446337#.
In *#36446337# I managed to enter "Protocol test switch" -> "MBN TEST" and switch my profile from Common-Commercial(I think it was this one) to Commercial-DT-VOLTE. The phone rebooted and everything is fine but "MBN Validate" is giving me an error when I run it and I can't test if it works because I'm currently out of the country and my temporary SIM provider doesn't support VoLTE.
It's probably nothing and the error is because of the lack of developer files on the ROM but I need people who can test if these profiles act like the flashing from the Qualcomm tool in the thread mentioned above.
So once again if you don't have VoLTE enabled and are feeling a bit courageous - give it a try.
I think the problem maybe for those that changed to Pakistan build on Android 10 and then switched to Singapore ex to get ColorOS 11 and dual SIM meant that things like VoLTE do not work on those builds.
I did it a different way as wasn't bothered about dual SIM. I was on A.46 UK , waited for EU to get ColorOS11 , then switched to EUEX on sec5 and downloaded ColorOS11 c.57 through Belgium VPN.
VoLTE is working for me. it's not present in SIM settings( WiFi calling is) however when I look at my call log there is a VoLTE HD icon next to all my calls, so is working.
Since being on ColorOS11, I have tried several different regions on SEC tool, EUEX dual SIM, Singapore EX, back to GB CPW to check still works and now back to EUEX. Build number always changes to different region in about phone when I have made any changes and check however VoLTE has always remained working for me and is showing as provisioned in engineer mode.
I am from Germany and have a phone with Vodafone FW originally. I switched region to Singapore EX, than installed the Pakistan FW and got C.5 and C.6 via OTA. I switched the region to EUEX (DUAL SIM) and didn't receive the update to C.57, so I switched back to Singapore EX and got the update to C.57 when using VPN Hongkong, which was quite funny.
VoLTE and Wi-Fi calling is working fine with Vodafone, but you can't toggle it in the hidden service menu, it's just active! You can activate or deactivate Wi-Fi calling in the regular settings, but VoLTE is just there, you can't deactivate it.
Both Wi-Fi calling and VoLTE are shown in the bar on the top. With the former Vodafone FW, VoLTE was not shown with an icon, but it was nevertheless working.
Hy here T-Mobile shown volte and Vodafone don't shows but on the status bar there is the volte symbol

The phone rebooted and everything is fine but "MBN Validate" is giving me an error when I run it and I can't test if it works because I'm currently out of the country and my temporary SIM provider doesn't support VoLTE.
It's probably nothing and the error is because of the lack of developer files on the ROM but I need people who can test if these profiles act like the flashing from the Qualcomm tool in the thread mentioned above.
So once again if you don't have VoLTE enabled and are feeling a bit courageous - give it a try.

I am in the same boat as you. I rebranded to Singapore to get ColorOS 11 update, to use 2 SIM and Call Recording, along with Theme Store, etc.
While on my previous phone (Xiaomi Mi9) I had VoLTE and VoWiFi and my carrier supports them and my SIM has that activated by my carrier, on Oppo Find X2 Pro it seems for them to work is needed special Modem Profile for the concrete carrier you use.
My Carrier is not listed at MBN Test Menu, I tried all the profiles available there, all Commercial ones and all Volte Branded ones and they are not giving me VoLTE and VoWiFi options available in Menu or VoLTE or VoWiFi functionality.
This method used to work on Xioami and Commercial EU Carriers profiles gave me the VoLTE and VoWiFi functionality with just Activity Shortcut access to this menu on Mi9 and simple dialer code to activate VoLTE and VoWiFi switch in Settings.
Oppo Find X2 Pro is not sold officially in my country and by all carriers here and that is why there is no Carrier Volte Profile for carriers from my country and thus it is not possible to activate VoLTE and VoWiFi with other Carrier Profile from MBN Test Menu.
Maybe if we find a way with a Dialer Code or some menu to activate the VoLTE and VoWiFi switch in Settings first this profiles from MBN Test menu will work...
I am out of ideas for now.

I'm pretty sure they force disable most of this stuff with region profiles (/etc/oppoRegion* folders)
At this point I honestly care more about GDPR protection,VoLTE and removing tencent/heytap crap than call recording and theme store which I don't use anyway.
So my plan atm is to wait for Oppo to release android 11 .57 .ozips so that I can flash back to european firmware then I'll see if changing region to EUEX Dual-SIM works and it's limitations.
This method might help people on EU roms with VoLTE, and I'll test it myself in the future, but at least for now *#36446337# lets us adjust MTU, 4G bands and some other smaller network optimizations.
Okay I don't know where to post this but I found *#649010# and this is where it gets into the spooky territory. I never tried toggling any of the options but I think "Full-port switch" option lets us connect our phone to the qualcomm diagnose tool just like the OnePlus phones from the Carrier profiles thread. I'm just documenting this code here so we know we have an alternative to the OnePlus LogKit.apk option in our Oppo phones.

Interesting to find out what these options do.
For some reason, non of these codes work for me now after doing the region change a couple of times.

We keep telling people - you gotta unlock every time you change region and even then the unlock lasts a fixed amount of time ex. 24 hours before it locks itself again

Unfortunately, the tool no longer works for me to unlock, the codes don't work. I'm stuck.

Works for me no issue. Try adding cloudflare dns to your setup, tether your phones connection to your pc while disabling your main connection and adding the number values from the original thread, fiddle with the loopback driver, disable firewall in windows or your router. Everyones connection and setup is different you just gotta find a way to make it work on yours.
Tl;dr it works you just got to tinker with it

Did you have the call recording option right after you switched region? I changed to Singapore Ex right after I got the phone, didn't see that option. Then I upgraded to ColorOS11, still did not find that option.

You have to give permissions to 'Recording' app, then open enable it in 'Call Settings'

Do you mean recorder App?
Already given all permission but still no call recording option, and the recorder only has cloud sync on its setting

Question VoLTE/VoNR settings

Hello all,
I work for a company that develops LTE/5G cores and am looking into the IMS settings in the Pixel 6. I am rooted and applied the Magisk VoLTE patch which had my device attach to the ims PDN/APN but I am noticing that the device does not want to register to the ims for voice services, assuming this is mostly a carrier setting I am wondering if anyone knows where to change this? An iPhone connects automatically and registers without any modification.
What I am looking for is the register name and cscf IP address fields so I can change those settings and register to the IMS for VoNR and calls.
Thanks
Same here cant get my device ims registered

I was able to get it registered after a while, it is not very stable though. I went and defaulted all the IMS setting in *#*#0702#*#* and then in the menu *#*#4636#*#* and it did register and was able to make a call. No audio but that might be on my end.
Are you connecting to a carrier or your own private core?
Im connected to a carrier

Rooted with Magisk patch? Have you check and enabled VoLTE in *#*#0702#*#* menu? I have been reading that has worked for some.

Yes im magisk rooted, i installed an app called pixel ims (google it) released a couple of days ago, its function is to enable volte/vowifi but it still dont work & reports that ims is unregistered i think thats my main problem, can you tell me where to enable volte in *#*#0702#*#* specifically ? Thanks

I would take a look at this forum if you have not, it is how I got IMS to register. https://forum.xda-developers.com/t/... info, you will,registration should now be ON.
Hit the menu in the upper right, select SIM1 Policy and find VOLTE_ENABLED_BY_PLATFORM. Again I would follow the link above first the Magisk VoLTE patch works great.

Is there anything to do to reset ims previous registerations ?, Already resetted ims settings im 0702 menu but nothing changed
Not sure what else could be it if you applied the magisk VoLTE patch as well. If you do the *#*#4636#*#* do you do you see VoLTE provisioned button set to enabled?
