As per Sony support articles, the Sony Xperia Z2 natively supports VoLTE. However, the carrier must have VoLTE support in order for the option to be visible from settings. If it's not visible, I should contact my carrier for additional support. I contacted my carrier yesterday and told me that they support VoLTE right from the very beginning (of their launch). They asked what chipset the phone has (which is a Snapdragon 801). They then asked me to enter the "4636" code on the dialer to check if VoLTE provisioned flag is enabled - and it is by default. Since it's on and the option is still not available, they asked me to contact the phone's manufacturer for a software update to fix it. I tried reaching support through phone and online chat. Phone - no one's answering. Live chat - "Offline/Busy" all day.

VoLTE for Xperia Z & Xperia X series.
Hi Guys, After many days of search and trials I have managed to enable VoLTE in Xperia Z2 & Z3 in Android 6.0.1. But this Method should work on Newer Z & X series models(till 2018). Only For Xperia Z & X series Your carrier must support VoLTE...

The option can be forced to be visible by modifying build.prop and config.prop found in /system folder. The thing is, it requires root, and rooting requires an unlocked bootloader. Unlocking BL will remove my DRM keys. To backup DRM keys, your phone still has to be rooted.
I saw that my phone's firmware is a "GLOBAL-LTE_23.5.A.1.291" and at the same time, it is identified as "1281-1985_R3D" which is a Customized Russian firmware. Service Menu reveals that it is currently using "amss_fsg_sirius_tar.mbn" which I believe doesn't have VoLTE support because when you navigate through the system folder, you will see 2 MBN files: "amss_fsg_sirius_vf_germany_volte_trials_tar.mbn" and "amss_fsg_sirius_volte_base_operator_trials_tar.mbn" - both of which has VoLTE on their labels.
My question now is: If I want to have VoLTE option on this phone (without rooting), what firmware should I use? Should I use (Germany) Vodafone's firmware (or will that make my phone SIM-locked)? I'm not sure what kind of firmware that uses amss_fsg_sirius_volte_base_operator_trials_tar.mbn.
By the way, I'm using IgorEisberg's Software, XperiFirm

Hi,
I want to buy an SOL25(au) from Japan. I googled around, some says that it is capable to use CDMA2000 network after unlocking, some says not.
The problem is how to unlock an SOL25 and is it possible to use CDMA2000?
BTW., Sony seems not open the ART option for Z series, Is it possible to enable it?
Thanks in advance.
Not sure about the first part but all Generic Xperias are able to use global bands
And for the second part ART is didabled because Art runtime is in pre-alpha stage hence why its not recomended to use and also why sony removed, Xperia Firmware cant run on art without ReWriting alot of it
I have a problem with Lineage OS unofficial ROM on Xperia Z3 Compact Tablet from this xda thread.
When mobile connection (using SIM card) is established, Android overwrites allowed Wifi channels settings with restrictions, based on countries. This is a well known feature, but for Russia it seems that any 5Ghz channel becomes restricted - even through channnels 34-165 are legally allowed in Russia (I can't see any networks, no matter what channel I use on my access point).
I want to find, where those restrictions are located, and fix them with appropriate values (I suppose there should be some kind of table with those values). I am sure that this is possible because 5Ghz works both on this device with official ROM and on xiaomi device with official and Lineage OS ROMs.
Unfortunately, ROM author is not interested in fixing this bug so I want to do it myself. I managed to get 5Ghz working using Magisk, Xposed Framework and module for fixing region - but that solution is damn unstable to I want to avoid it and make a normal fix.
By the way, setWifiCountryCodeFromMcc is met in this source and it calls "setCountryCode" from here. I just need to go a little bit deeper to find restricted channel options - but I don't know where and how.
Just wondering if it is possible to spoof your phone model (in build.prop or elsewhere) to make a particular phone work on a particular carrier.
i.e. Huawei phone on Verizon
How does a carrier know which phone you are using?

Regarding your last question. It's read off your device and transmitted to the carrier.
To spoof/fake I actually only know one tool that I'm using myself but the device must be rooted and also running Xposed. The latter means the ROM must be Oreo or lower as Xposed isn't available for Pie; second with Xposed installed you're never going to pass the SafetyNet check if you require that. Finally, depending on your ROM version use XPrivacyLua or XPrivacy, both by M66B, and I always suggest the pro version to mainly support the developer and the development but also to enable some additional, useful features. XPrivacyLua has a companion application.
Hi all,
I'm considering to get a Z5C, but I need VoLTE working. I know that VoLTE is working with the stock ROM, but how about Lineage OS or other custom ROMs? Does anyone have hands-on experience with that? Any suggestions much appreciated!
Cheers,
r.
VoLTE is definitely not working on any LineageOS ROM, no matter what version you are using.
Ok, thanks for this info. Here's two more questions:
1. You wrote "LineageOS" - do you know of any other Custom ROM where VoLTE is working?
2. How about VoWLAN aka Wifi Calling: Will it work with custom ROMs?
Thanks.
r.
1. No. My guessing is, that some IMS related stuff is missing. We (unofficial LineageOS devs) have tried it, but we failed. The normal telephony function has been compromised.
2. I don't think so (see above).
I'm sorry.
Ok - thanks for your efforts anyway!
VoLTE works mostly only with T-mobile firmware.... but you have to flash this firmware... stock z5c dont support this.... if you flash it "with your country local operator firmware"..... will VoLTE work...100% T- mobile speciallity....
You can flash it by yourself, but be sure you dont have phone with unlocked bootloader.... if you make it after, you loose IMEI and mobile is 4 parts only....
Thanks for that info and the warning! Did you try it yourself with LOS? I have already unlocked the boot loader to ...well, install LOS. But afaik it is possible to lock it again using flashtool. Is that what you did?
I have had many Z5 compacts.... first was with unlocked bootloader.... I did know nothing before.... so I have tried flash it..... not finished, error.... started phone, No IMEI at all.... only Wifi worked No Simcard read, so I used it 4 parts - crashed display.... and for study how to dissassamble all. It´s nice when you know how to dissassamble hole Z5 compact and reassamble new one
Since then I buy only Z5 compacts with factory locked bootloader, OEM locked, from normal users....VIRGIN phones they are perfect 2 flash.... also i have had one piece, there was Lineage os before to anroid 7.1.1 returned, opened bootloader... and it has non functional cameras and flash.... no hardware problem, it was because of unlocked bootloader and this Lineage OS. Somebody bought it from me to use it as a bike navigation
I have relocked the bootloader via Flashtool... but cameras were still kaput 4 ever.
Installing Lineage OS or unlocking bootloader can (or relocking bootloader after - I dont know) destroy cameras and flash lighter..... on 7.1.1 android. It will not destroy cameras on android 9. Fx sony XZ1 compacts..... but you will still loose some functions of cameras + codecs and so on.
If you do so, there is no way to fix it back....
Unlocking the bootloader no longer breaks the camera on Sony Xperia devices running Android Pie
Unlocking the bootloader of Sony Xperia devices running Android Pie no longer totally breaks the camera like before, but not every feature will work still.

Hi, just wanted to know if we can flash those .OEM files from Sony Xperia XZ2 to Sony Xperia 1 iii XQ-BC72 model. Bootloader is locked and updated up Android 12.
Here in my country, Volte is supported on Sony Xperia XZ2 model for two major carriers.
Was hoping to flash the OEM files to enable volte on Sony Xperia 1 iii phone.
Can anyone confirm if this would work?. Newflasher might throw some signature issue or device mismatch. How can we handle this error?
Would you kindly advise where to get those .oem files? I would attempt this using my Xperia Z Premium; that had been provisioned by my network for VoLTE too.
Sony seems to put some apps, apks here:

I got the camera apks, that come as system apps. There installed as a update. Kinda cool, Thanks Sony.
