VoLTE AEX 5.3 - Lenovo ZUK Z2 (Plus) Questions & Answers

Dear all,
I flashed ZUI 3.5.xxx through QFIL in order to make a VoLTE call to have it in a custom ROM (AEX) afterwards). Enabled HD calls in ZUI settings, the corresponding HD symbol in the status bar appears.
However, when I initiate a call, the call is canceled automatically almost immediately. Incoming calls work just fine.
Please help me out here. I have been flashing ROMs, Modems etc. forth and back.

I understand you are in a problem and it might be very important but wrong section.

First of all wrong section to post this. Secondly, which version of AEX you're flashing?, most ROMs(including AEX) had this issue in their late January to early February builds but after that VOLTE working absolutely fine in all OREO ROMs. But if you still have the issue then post it(with logs) in AEX thread to get help from the dev of AEX.
@xantharax you need to move this.

First of all, thanks for moving the thread to the correct section.
I use AEX 5.3. However, I am not sure if the issue is AEX related. I started from scratch by QFIL flashing ZUI 2.5.xxx, enabled VoLTE and made a call. There is no symbol that indicates whether a call is made on 4G in ZUI and hence, I cannot verify if the call indeed was on 4G. Mobile data at the same time were on 4G. I consequently upgraded to ZUI 3.5.xxx and tried to make a VoLTE call but it got canceled almost immediately. The phone I tried to reach rang for a fraction of a second. Incoming calls work on 4G.

[HELP] VoLTE issue

Jio sim user here. Everything was fine until I decided to move to another ROM from Community Build. Found that VoLTE is not working on any other ROM, not even Oxygen stock. I tried locking bootloader and going back completely to stock but still VoLTE is dead. Don't know what I messed up but any help would be appreciated.

if you don't have a proper reply please don't comment. I asked about VoLTE not the Jio app. I know I can use it too.
At the moment no other Marshmallow ROM for the oneplus 3 supports VoLTE by itself expect the Community Builds. All 7.0 Nougat ROMs do give VoLTE support. I myslef am on AOKP N.
Flash a Nougat ROM and you'll get back your VoLTE.
I'm on CB 3.5.3 and I can't see VoLTE settings, here two pictures:
What's the problem?
Is the "Enhanced 4G LTE Mode" On under the Cellular networks setting?
No, I haven't.
VoLTE work around on stock / CB
Clean Flash Stock / CB rom using twrp .
You first have to extract 4 files contained in the zip file attached .
Now make a efs backup from twrp
Now go in twrp>backups>device serial number folder>the most recent backup you made folder
And paste the 4 files and replace them with your efs files Then restore EFS back up only using twrp.
That worked for my friend on 3.2.6 stock who completely lost VoLTE , tried every thing found this solution by hit and trail hope it works for you as well.

Misleading
I can't find the cellular network settings options after the nougat update on my OnePlus 3
Did you try stock Nougat? I can no longer see the 'VoLTE' icon in Nougat but voice calls work fine without the need of any app. In Marshmallow VoLTE icon used to appear. If you see '"Enhanced 4G LTE Mode" option in cellular settings menu VoLTE should work.

Maybe im selecting the wrong option but even though i ticked the enhanced lte option im still not getting VoLte on nougat.
As soon as I initiate a call it automatically drops to 3g.

Strange. Not sure why it is happening so. I got a Nexus 5x running Nougat too and it also doesn't show any VoLTE icon but everything works fine. Data, VoLTE calls etc.

Sudden AOKP ROM problem ???

I had flashed AOKP 21/2 build. It was working great for a week with little overheat problem . Nothing serious though . But from today onwards it started restarting on its own. It happened couple of times and now all the bugs people have mentioned starting showing up. It makes that crackling sound when headphone is inserted and won't recognize it . Network won't come after the restart. That brightness fluctuation and almost everything. Does anyone has the same problem ? Cause for a week it was working great. even my video recording was fine.

It is the most stable rom i found till now and VoLTE also works pretty well.

The modem you have installed must have come from a stock om with volte support in order to continue to enjoy volte on your custom rom. the custom roms do not provide anny modem software and hence if your stock rom did not have volte you will not have it after flashing a custom rom.

Just suggesting
I tried all the oreo ROMs (except Jaguar- well I installed it but didn't find some things according to my taste, so uninstalled it) , you can surely try it.. considering OP's work on jaguar nougat I am sure it will be good.
Anyway, coming back to question. I will say as of now-
1) AEX (most stable and bugless amongst all), only rear camera portrait mode as of now.
2) Validus (first to have both front and rear portrait mode), just 1-2 bugs like dt2w not working, lockscreen cannot be waken up using home button, only using power button, some heating while charging - compared to other ROMs), otherwise quite stable and good performing rom. I would have sticked to it if not for the bugs I mentioned above.
Here you have both's pros and cons.. upto you now.

Jaguar r14. The most stable rom for it. No doubts

are you a heavy user and what about sot
Try AICP 13.1 based on Android 8.1. It's working fine with GPS, VoLTE as of now! Been using it for a week now! Very smooth experience.
It's pointless to discuss about what ROM is the best, as most ROMs cater to different needs.
It's like a person asking what's the best food or what's the best religion. It's a subjective matter.
That being said, if you're just looking for recommendations for ROMs to try out, you'd first want to understand how you want your device to perform, i.e. how your use cases for the device are like.
If you are a heavy gamer, avoid LOS-based ROMs as they tend to cramp the device performance. Look for Vulcan-enabled ROMs if you use emulators like PPSSPP.
If you are a person who focuses on long lasting battery, some of the minimal ROMs like Omni or Validus will help you out.

Try to update the baseband . I'm using Baseband 2.0.079 . Even before I updated the baseband Volte was fine with JIO sim.
Try to use this link for the baseband 2.0 and don't worry , the phone vibrates too much while boot.

VoLTE is a PIA for developer's. not just because the code is proprietary (meaning no access to the source code).
the Dev's so far have not focused to fix VoLTE for Oreo hence the issues. they focus on other major more important fixes first.
Oreo is a major re-write to C++ compared to Nougat.
VoLTE on 14.1 is stable because the Dev's have figured out a proper way to make it work. Which is not yet the case with Oreo. so if you want stable VoLTE stick with Official LOS 14.1.

How to flash stock modem .
I am on AEX.
---------- Post added at 07:50 AM ---------- Previous post was at 07:46 AM ----------
I think AOSP roms have volte problems.
When I am on AOKP os volte working fine..
Yesterday I flashed AEX which is based on AOSP.
Volte gone.
One way to get back the volte is by changing the sim card from 1 to 2 or vice versa. This will get you volte. And then if you want to change the sim cards back to original then do so. The volte will stick.
Other one is, flash the stock ROM modem or an LOS modem. It worked for me with stock and RR modem.

Hi, one plus already shared that u can go back to its previous version but for that u have to wipe full data from your device. Try to downgrade and then update through oxygen updater. It will help you download full update for your rooted device.

2 times this has been asked in a forum of loads of people. Do the people it has happened to think they have done everything right? as I myself would look and say I form a rather small percentage with what happened to me and come to the conclusion it must be the way I installed it and try installing it properly without anything else and work my way through.
The last post was days ago being 2 threads down and clearly stated it had to do with magisk for that person.
So common sense and a bit of reading would make you think it's obviously a module or magisk version.
Why don't people read and see no one else is really suffering from this problem so just putting up oos10 flash and camera broken doesn't help. Maybe at least put what you did and used step by step so anyone who did want to help you doesn't get shot down as it wasn't the quickfix answer you wanted.
PS. by that I mean what modules do u have installed and what mods have you done as having magisk modules can cause all sorts of problems and edexposed in an update from 9-10 is rather stupid thing to do seeing as half the modules used in 9 don't support 10 unless I'm reading wrong and you installed edexposed and correct modules for your software afterwords.
I'm facing same issue
Since Oos 9.0.11 the camera and flashlight isn't working
Tried all flashing method but give same issue
Tried all custom rom where it using Oosbeta blob-Oos stable blob will give same error
The only one custom rom where the camera working is msm xtended
