Question Enabling Volte - Sony Xperia 1 III

I recently received the iii and I really enjoy it so hoping to overcome some obstacles so I can enjoy the full experience.
It was preinstalled with Hong Kong firmware, I successfully flashed it with Sea firmware but I have had no improvements. I am hoping to enable VOLTE and access all my telcos frequencies.
Does anyone have any suggestions?
Thanks in advance

I successfully flashed my Hong Kong version phone with the US ROM, so you can try to flash it if you found a ROM for your country. Also try to install or update "carrier service" in google play.

I updated carrier services and nothing has changed. I might flash another region onto the phone as there is no Australian region available at the moment and I don't expect a version to be released.

Hong Kong SGS II Firmware Update?

Hi Guys
I have a SGSII, which I got in Hong Kong a couple of years ago. It came pre-installed with Stock Samsung Firmware ICS 4.0.3. I currently living in the UK and was wondering if I did a Firmware update using Kites, would it install you UK version of the firmware instead of the HK version?
If it's got the HK firmware/CSC on it, it will update to the latest for that region; where you are now is irrelevant, it reads the CSC info off the phone to determine what firmware to upgrade to, assuming there is a later firmware for that region.
But it's a moot point. Why would you use Kies for anything ? Flash whatever stock rom for whatever region you want with Odin.

To be honest, I am a noobie when it comes to the advanced aspects of android devices. So I've always followed the mantra of always following the manufacturer's instructions to the letter. Also I don't want to loose all my user data for my game of Asphalt g

Rebranding....Vodafone UK

I am trying to switch my OS to the official one supported by Vodafone. In the coming weeks VF UK will be launching wifi calling and I want to get in on that. The problem I have is downloading stock firmware, problem is the firmware also seems to install both German and UK based apps.
Does anyone have any advice to stop this from happening....its not a big problem, I am just concerned I maybe not installing correct firmware, even though I have sourced it from Sammobile.
Any advice?

Quick firmware question.

I got my wife a E2306 (16bg) for Christmas. I charged it, updated the firmware then put in her Tmo (USA) sim card. It says the firmware is up to date but she's only on A.2.99 and from what I've read on this forum and the Sony site, she should be on A.2.167. Do you know if this is due to being in the U.S. or something else? Do I just have to flash the latest firmware to it? Not looking to ROM or root her phone. It's an unlocked model so it shouldn't have to do with my carrier. Especially since I updated prior to putting in the SIM for the first time.
In USA, the latest available firmware is 2.99, so your phone is up to date. You could flash a firmware from another country if you'd like to have a 2.167 version. Use Xperiafirm to check the available versions from the diferent countries for your model.
Thank you!

Flash Different FW region

Hello,
I have LG H860 version but it have the TWN firmware. Is it safe to flash the firmware for GCC since I am here in dubai. Here's the FW:
http://lg-firmwares.com/lg-h860-firmwares/
H86010g_00_OPEN_AME_DS_OP_0428.kdz
I have now H86010e_00_OPEN_TW_DS_OP_0614.kdz
Thanks. I'll be waiting.
The answer is intresting for me too. But until then an information: to my TWN H860 arrived today the V10g-AUG-08-2016 update...
As long as your device model matches (i.e. H860N -> H860N), you can flash the roms from different region.
However, you will not be able to receive OTA Updates, as they are pushed to devices based on their IMEI info.
You can check your device info form the link below

I'm from Hong Kong and I also got an H860N (Taiwan Version).
I've also flashed HKG (Hong Kong) Rom to enable the VoLTE function.
I received security updates (to patch the Snapdragon root exploits) but not OTAs.

Question Flashing UK version of XQ-BC52 on TW XQ-BC72 (.oem files for Volte & Wifi Calling)

Hi Everyone,
Can anyone help me with process for flashing UK version firmware of XQ-BC52 on Taiwan version of XQ-BC72. I need to know which firmware files such as ".ta" or any other files to be removed from firmware folder before flashing. The UK or US customization versions supports volte and Wifi calling in my country.
Currently the Taiwan firmware version is at 61.0.A.23.20 (android 11) and UK firmware version is at 61.1.A.2.211 (android 12)
Can I just flash the .oem files of UK firmware to TW firmware?. But, since device firmware versions are different, flashing may fail and corrupt the device. Can you confirm if this is safe to flash?.
Request your help!

I think yes but r u sure that customized UK fw supports voLTE and WIFI calling? the switches are in the settings? because I have the same model but with eea customized and have no volte or/and vowifi switches.... My carrier supports them btw
I've been told the customised SEA also has Volte and VoWifi wnabled, but I never got any joy out of it when I flashed it into my HK BC72 device. I have tried the previous firmware revision of the UK one, but nothing there either.

So if I flash it to my XQ-BC52 will it affect anything? I don't want to lose anything, but I want to use volte I have no idea why it isn't enabled when all of the carriers on my country support it
I would first update it to the newest TW Firmware and check if it works (so you can update, without loosing personal data).
If it still doesn't work, I would try the HK firmware, because of Over-The-Air–Updates (OTA). I have VoLTE and VoWifi in Switzerland with this firmware.
If it still doesn't work, try the BC-52 firmwares (but you loose OTA Updates).
Please just check after flashing a new firmware if you have the functions. If it works, first do a repair with Sony Companion before starting to install everything (like apps, files....). This makes a clean install and avoids a lot potential of failures/problems.
I bought the phone in Etoren and it is the model XQ-BC72, I live in the UK, and the update I received via OTA and is installed is 61.1.A.2.211 release-keys. you shouldn't, I guess Sony recognizes you're in the UK and installs the correct one

You won't lose your data if you explicitly tell it not to clear userdata off your phone, if that's what you mean. If, however, you're referring to certain functionalities I sometime hear of getting lost, then I myself haven't noticed such with all versions of firmware I have tried out so far.

I've yet to do a clean install, the way you have described it. I guess I'll do it just like that when I've given up on trying to activate VoLTE and VoWifi on my phone. It's interesting that your Hong Kong phone has that function over there. I suppose there is some substance in Sony's insistence that the one's network provider be engaged as well.
I was considering getting the Xperia 1 IV which would be a nice upgrade from my Xperia 1 II but with volte not working it would push me away. I managed to get it working on my Xperia 1 II by simply flashing SEA firmware. It was straight forward and has worked flawlessly with OTA updates. It doesn't look like the Xperia 1 IV will work that way. Even if I was to flash SEA firmware it looks like volte still wouldn't work. Come on Sony sort this problem out
