HI. I am in the UK, on EE, have an i9305 (Galaxy 3 LTE) and have tried a few different ROMS and have had absolutely no problems on 4.2.2.
I tried the Supreme ROM 4.1.2, but upgraded to the LiquidSmooth ROM 4.2.2, v2.2 (STABLE) and have had absolutely no issues. In fact, I would recommend it to anyone.
Why do you go in and select the Carrier? Whenever I have flashed a ROM, it has automatically selected EE as the carrier. Is your phone unlocked?
Don't know what's wrong with your situation. Are you wiping properly before installing each ROM? Are you installing Gapps with each ROM?

If you're getting the T-Mobile network, you don't need to unlock your phone. You can try out various websites like HTC-Codes for a paid code to unlock your phone. There is also a free option, but it's a bit involved and relies on your phone being on 4.1.2 firmware. URLs are -

ok quick issue its saying its on ee and i have signal however if i take it of wifi i have no data symbol and its not connecting to anything eg fb or internet any ideas

Never had that problem tbh, but make sure data connection is enabled in data usage settings.
Failing that make sure you have the right apns installed in mobile network settings (I'm on orange and have orangeinternet and orangemms). If in doubt, ring them and ask you to send your Internet settings to your phone for you.

4.2.2 update in UK??

When will the 4.2.2 update be released in the UK? Seems like it's been out for a while, yet my phone still hasn't found the update using either OTA or with PC Companion on my laptop.

We don't have the insight to say. Nobody has. And no crystal balls.
4.2.2 has been out for a few days only and is clearly rolling out across the piste.
Just wait patiently or use one of the other Generic ones if you're really that desperate. They're all basically the same apart from minor app differences.

I think Vodafone has released it someone on another forum updated his to 422 via Sony bridge on a Mac.

Never.... (joking)
Considering we were left out of the last few updates wouldn't surprise me if we are the last to get this one.
So I would guess a month

You have a UK unbranded device? Customisation number 1270-7689? Or some other UK device?
Not booting up my PC to find out if this is true or not, as other methods of checking are still showing 434 as the latest available for UK unbranded.

Mines was a VF UK handset upgrade - so branded to them. The phone itself didn't report any system/software upgrades, but as soon as I ran up PCC and plugged it in, PCC kicked off the upgrade.

Just use the Sony original Japanese update it doesn't change the language or anything and everything works out is the official Sony update and u just flash it with a flash tool no wipe of data or anything and u can easily root it with doomlords rooting method. It's a one click root.

Just change to a different generic customization. Some people seem to think that there is something special about UK firmware, but that isn't true at all (except that it seems to get updated last). All customizations contain the same baseband, kernel and core. The only difference is the bundled apps, build.prop and some overlays. I think 'Generic ES' is the best customization to change to. It contains all Sony apps (so you won't lose Video Unlimited or anything), of course it also contains all languages and it seems to get updates first.
Also, please stop asking when an update for a certain customization will be released. Nobody will be able to tell you, so it's completely useless to ask. There are ways enough to check the latest version for your customization. I have a list that I update daily or even multiple times a day, you can also create a browser bookmark to Sony's Firmware Update Server (see same thread) or you can use this web check: http://scavenger.ch/sonyupdate/.

Don't worry, it should come sometime this decade...we might even get the firmware update that everyone else has had for 2 months before 2017...wouldn't that be great?

Instead of waiting weeks/months/ages and complaining, just change to a different firmware customization like everyone else did. What are you scared of? There's always the possibility of changing back to 'Generic UK'.

That doesn't exist. In Japan, the Xperia Z was only available through the carrier NTT DoCoMo, which had a slightly different version with a different model number (SO-02E).
Check this list for the available customizations: [INFO] Latest firmware version per customization (region/branding). For the UK, I would recommend 'Generic ES'.

Downloading the 'Generic TW' FTF and flashing it with Flashtool, or changing your customization number in build.prop and updating with Sony PC Companion will give exactly the same result. 'Generic TW' is the only customization that has been updated for C6602. It also seems to get updates first each time. So I recommend to use that firmware.

I will sell my XZ and buy Galaxy S4 i think, its not about changing customization etc it shows how Sony treat UK customers...

Good luck with your (plastic) Galaxy S4 (with ugly *** TouchWiz) then. Hopefully Samsung will release updates faster to the UK
Do you really care so much about the 'Generic UK' customization? It's not like it contains any special features that can't be found in other customizations.

Xperia Z from Bell Canada (C6616)

Just picked up my Xperia Z from Bell - here's a little information on the device, as after searching for a while there doesn't seem to be much out there about this:
Model Number: C6616
Android Version: 4.1.2
Baseband Version: 9x15A-ACEFWMAZQ-30110041-32
Kernel Version: 3.4.0-g6df7905-02328-g70ed36a
Build: 10.1.1.A.1.319
Customization Version: 1275-6311_R2A
Also, rather unfortunately, the bootloader cannot be unlocked (according to the Service info > Configuration page).

Can you tell us if the screen is better? I saw some videos on the Bell website and it did look better. I was gonna go check out the Bell store today but didn't have time lol

I don't have a lot to go by in terms of better than other Xperia Z models, but compared to my SGS3 it looks much better and is actually visible in direct sunlight.

Not yet - this is the first Sony device I've owned (used to Samsung devices and the various Nexus'), so I'm a little gun-shy regarding flashing things meant for different models.

Tried rooting it today and, as expected, it failed.

Use DooMLorD to root, I think it should be fine.
Would you be able to backup your rom to FTF file?
Here is the instruction to make ftf file of your rom.

The update made the screen look a lot better but that was with 253 version already and 4.2.2 made it even somewhat better again and camera too.

Tried Doomlord's without luck, but I didn't use the new method to flash the other kernel (was fairly unsure if I would soft-brick it). I'll follow that guide and post the resulting file, though.

I flashed its baseband but it didn't work unfortunately.
This Rom only has band 4 LTE also even though Bell says it has AWS and 700.
It couldn't pick up t-mo LTE too.

For any other Bell users who are new to Xperia devices and unsure of flashing, I successfully flashed this 4.2.2 stock firmware using Flashtool (left FOTA, BASEBAND, and UNKNOWN unchecked). I had to add the Bell APN settings, but everything works!
Additionally, I rooted using this guide, but when I got to step 11, I reflashed the kernel from the first firmware image I linked instead.

So if I get this one, unlock it and flash standard firmware, can it be used with Rogers and its LTE?

Rogers and Bell both use the same LTE bands, so it should be good with the network unlock. Switching firmware is really only required for rooting/getting 4.2.2 at this time.

So bell's firmware is standard or it's a custom one with bell's apps per-intalled (aka you have to wait for them to release a new version 2-3 weeks after everyone else gets it)?

Bell's firmware has their apps, and is subject to their release schedule, but will work with other carriers - it's just the network lock that prevents you from using another carrier. However, if you're looking to root, or don't want the extra Bell branding in your face, switching firmware is a valid option.

Never used the 6606, or any of the other models. From the looks of things, though, it's a difference in basebands and supported frequencies.

laslow, I flashed baseband off the ftf file you posted, there is only band 4 LTE, not 700 (band 17) as stated on Bell website.

I can't disable the data roaming with H3G (in Italy) and Xperia T. I've disabled the data roaming but, after a while, if I go to the options menu, it is enabled again, without any action of mine. The firmware is the 9.1.A.1.140.

If you have a sd card use the backup tool that's installed on the phone, this works just fine. Rebooting the phone didn't work?

It is a bit late but i'm replying just to say that I have the same problem. I always had this problem with this phone e no reboot ever solved it. My phone keeps getting roaming over EDGE.

I have an xperia z and I have the same problem. Sony does not have any intrest in this. There is a big discussion in talk.sonymobile but sony says that it's all good and it's my fault.
so now I'm looking for a lawyer to get refound from sony.
Even if roaming is disabled when shifting from 3g (h3g) to gms (tim roaming) data tranfer is always on.
Any idea?

VoLTE, VoWIFI, 5G - carrier settings by Sony

Hi all,
Support of Sony doesn't have any idea, how it works....:
I bought a EU-device and use it in Switzerland. Unfortunately, they didn't integrate the Swiss carrier settings. Due to this, I don't have VoLTE, VoWifi (Wifi calling) and 5G.
I contacted Sony by phone and they told me that the device seems to have defect, that's why it doesn't work. So I wrote an e-mail to Sony support and they answered that the hardware is only capable to have these functions for the countries it is build for. My reply was that this is an EU-Version, so the hardware isn't the problem, they just need to add the carrier settings and if they know, when they will add them. Answer of the support: No, it is the hardware.
It is really frustrating with Sony. They have build such a nice device, but with this support, they shoulnd't be suprised about falling sales.
I was thinking of open the bootloader with Magisk and try to add the settings by myself. But first, I have never done this and I am not sure yet, what I have to do exaclty (step by step). Second, I loose the guarantee. And third, I am not sure if banking apps still work afterwards.
I really love this device, but I am a little frustrated about Sony.
If you have an idea, how I can solve this problem, you would make me happy

Flash firmware with Volte support, that's all.
Envoyé de mon XQ-AT51 en utilisant Tapatalk

I tried this already (several different localizations), bitit didnt help. The problem is, that Swiss providers didn't integrate their settings into Googles carrier services, but into another database for manufacturers. Unfortunately, Sony didn't do that on the Xperia 1 ii (even if they did it on past Xperias).
But I am most frustrated, that their customer care blame it on the hardware, but it's a software problem. Even after explaining, they don't wanna check it with a specialist. So trumping something, which isn't true.

Maybe you should contact your provider. Unlocking bootloader won't help.
Envoyé de mon XQ-AT51 en utilisant Tapatalk

According to Swisscom, everything is ready and the system is waiting for the device to register in IMS. But as the mobil doesn't have the carrier datas, it probably can't do it.
So I am back at the point, where the mobile needs the settings implemented for Swisscom...

We need to wait for flash firmware with Volte support, that's all.
For now FlashTool is not supporting our device.
Later just flash US frimware you will loose double sim but you will get VoLTE and WiFi calling. I did that on Xperia 1. It was easy and satisfy choice

I have an XQ-AT51 and also tried the UK-version, which support VoLTE/VoWifi. But as mentioned, the carrier settings of Swiss providers are missing.

I really don't know if it can help, but, have you already tried this way? here

The mentioned switch in this post is greyed out on my phone and my phone is also not IMS-registered (even my provider is offering it - I have also a second SIM for the same number with an Xperia 10 Plus with VoLTE and VoWifi). So I am pretty sure, it is only about integrating providers/carriers settings. But as Sonys customer care doesn't care about it (only this sentence shows that something is wrong there) and they don't want to check it internally with an xpert on VoLTE/VoWifi, it is frustrating.

Hey PlatinCH, any news? Did you manage to get VoLTE/VoWifi working?
That's the only thing holding me back from buying it

Yes it is quite confusing for sony, i used to flash xz premium and xperia 1 with SEA firmware on my HK device and both able to use VOLTE and VOWIFI in Thailand. So i just wait for SEA firmware to release for Xperia 1 II and i flash it over to my Xperia 1 II (HK) last night. This is quite problem the volte button is there but not work, as well noticed that IMS is not registered although it trigger on but greyed out. I think pproblem is with Sony.
Anyhow i recommend to use New Flasher now as it support Xperia 1 II, and i am contributor to the dev since Xz Premium day so the dev is very updated and quick respond and it is simple and easy to use.

Question for the OP. Have a checked the modem config files to see if your carrier is listed in there? Also have you checked to see what modem config file your phone is currently using? Just type in *#*#service#*#* and go to service info, then choose software info. Your modem config will be listed at the bottom.

Quite sure it's listed there,
This phone will always select ROW Commercial config.
Don't know if this a bug or a feature from Sony

has anyone found a solutuion for wifi calling?

normally you just need to flash your country. if you live in uk then flash uk. it used to always work previously, but in xperia 1 iii to make cross flash it wont be always work and you will lose ability to OTA. but if not cross flash and your model is the same model number in your country volte and 5g will work, still OTA is not working anyhow you need to flash update manually everytime

If you are flashing the firmware for.your region and volte doesn't work then you won't have much luck flashing different region firmware. However if you want try flashing SEA firmware if it's only compatible with your model
