Changing firmware so that VOLTE works - Sony Xperia XZ1 Questions & Answers

So i had my Xperia xz1 from Dubai which is already on the latest firmware update of June (47.1.a.12.205). And right now i reside in India ?? where am using Jio Volte network but my u Xperia ain't showing any options to switch on volte and then i came across some feed which suggests to change the firmware on basis of country region. So my question is which country firmware should i download depending on the fact that i don't loose any other features and which country is the first to receive the latest firmware updates.? And please suggest a link which can guide me to change my firmware.
Thanks.

How to get old version of firmware via pccompanion?

Hi !
Using this tutorial http://forum.xda-developers.com/showthread.php?t=2233350 I can change the customization number, and I can get a firmware from another region but only serves to the newest version
How could I use it to force the repair with pccompanion and get older firmwares (like gingerbread)
Thanks!!

Send from my xperia p
Hi! Have you tried flashing an older firmware with flashtools?
Yes, but look for the version of my region, that any other region marks my operator (virtual mobile operator) as an operator in roaming, and the version of my region (Spain) brand as a normal operator (without the R roaming ).For Xperia P I have not a FTF from Spain (IBERIA)

Possible to Change Device Default Region?

So I ended up ordering my Z3 Tablet Compact from a Japanese retailer and when I check for updates using Sony's Xperia "Update Center" it still links to the co.jp website. Is there anyway I could change the region so that when I do my Lollipop Update I could fully switch over to US default for everything?
I'm using the 16GB Wifi model SGP611 currently on Build Number: 23.0.1.A.0.167
yes, Flash a FTF file for the region you want. You could flash a US FTF now and wait for the US lollipop release, or you could flash the noba lollipop now.

Sony Xperia XZ1 O2 Firmware

Good Morning All,
Is the official O2 Branded firmware available for download?
Does anybody have a link to the official O2 Firmware, in order to enable wifi calling with O2?
I've brought a standard Unlocked XZ1 which doesn't have the O2 firmware so I am unable to use WiFi Calling.
Many Thanks in advance.
You can use a software like Xperifirm to download every single firmware

You don't need a branded firmware to get WiFi Calling working with O2. In Germany (customized DE firmware) it works out of the box! :good:
Which country you are using your XZ1 in?

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
