I very much doubt it, as the hardware is almost certainly different. (The model number is).
At a minimum:
1. The Japanese version supports Saifu Keitai (Felica) in addition to NFC.
2. The Japanese version has 1seg TV
3. IR support, as is demanded by Japanese consumers (IR is universal in Japan for transferring contact info between any two phones)
4. Of course all the Docomo APN settings, etc. are baked into the Docomo firmware.
5. The frequencies supported may be different (unsure)
6. The amount of "ROM" is different. (This means flash memory?)
If you don't care about the above, there is a chance you might be able to flash the UK firmware with only a loss of functionality for 1 and 2 - but trying to flash the Japanese firmware on an English model might fail when it tries to access the hardware that the overseas models don't have.
For example, if you flash a ROM for the global Acro HD into a Japanese Acro HD it mostly works (except uhm the battery won't charge until you fix that which has better be fast!) I am not sure if anyone has tried the reverse.
There are many small details too, like "area mail", which is used for earthquake alerts in Japan, etc. Also bear in mind that unless you ask Docomo to unlock the phone, it's locked to a certain type of DoCoMo mini SIM. Also, there are baked in apps for DoCoMo's email service, and their annoying "DoCoMo Pallette menu", etc.
What are you trying to do, and why?

[Q] Developer support on C6903

Well now it’s my turn again to ask a question. :silly: I’m going to buy a new phone as my old Galaxy note recently broke. And since Samsung are really bad at supporting AOSP/Cm development I’m thinking about getting the Z1. The thing that worries me is that in Norway the only Z1 model in sale is the C6903. Seeing that the there are a lot of different Z1 models I’m worried that only one of them is going to get the AOSP/Cm support that I’m looking for. So if anyone got some information if getting the C6903 would be a good choice for AOSP/cm support, that would make my choice a lot easier.
Thanks for any answers in advance.

I am not 100% sure. Only change among various model is the radio bands. it is mostly only hardware dependent. If any dependencies exists it will be only in baseband firmware which is different from phone OS. qualcomm uses AMSS as their baseband OS.. it is released for sony phone by sony only.. even if the phone is running any kernel or os.. baseband firmware will always be from sony. and you can flash it separately

question about xperia z...

Im on T-Mobile and will be going to a Sony store locally to possibly buy a Z. I have a Galaxy S4 currently and are tired of Samsung phones and total lack of updates from t-mobile so I will be selling it. The Sony store sells both the US unlocked version and the t-mobile version. The unlocked version has been updated, right? And receives updates directly from Sony? The t-mobile has not been updated yet? Also does the unlocked version get HSPA+ so data is fairly fast?
Thanks for the help

Yes on all of your questions. I'm not sure if it gets HSPA+42, but it will get 21 at least.

alternately all official sony updates will be available to dowload here on xda faster that it will get pushed to you. unless you're the first one getting it

N9500 UK - anyone used this and is it any good?

Unfortunately in the UK, the only way to get the Deep Sea Blue variant would be to buy the N9500. I understand that this was built specifically for China markets, but it should have the right network frequencies for the UK. I was just wondering if anyone has bought one of these before, and whether there's any quirks in the device compared to the UK model? Cheers

Using Note8 N-9500 for 3 weeks now

Yes. Note 8 N-9500 is Hong Kong/China version. I have been using it for 3 weeks now, but I would not recommend it.
I have Hong Kong version. (China version doesn't support Google Play Store. Avoid it!)
Here are some negative things that I found out so far.
1. It works perfectly with UK network frequencies, however, you can't enable VoLTE or wifi cailling.
This is really downside. it keeps saying my current software does not support VoLTE.
2. It doesn't have Samsung Pass. Some apps require it to log in with your bio info (cf. finger print etc.), so it is bit annoying.
3. Android Pay works fine.
I have not use Samsung Pay yet, but Samsung Pay is registered as Hong Kong so you will get promotions from Hong Kong market only and you can't change it.
4. If you contact customer service through handset it automatically connect with Samsung Hong Kong Service centre. ha ha
I have tried to change it with other CSC roms such as Europe versions, but Note 8 N-9500 uses Qualcomm Snapdragon 835 not Exynos as Europe or Korean version.
At this point as far as I know it is impossible to use other CSC roms.

Have you managed to flash Europe firmware successfully?
I've also got N9500 deep sea blue, the only reason I bought this version was for the colour!
I quite like it but would like to have volte

SM N9500
No I haven't. As far as I know EU firmware doesn't work with this SM-N9500.
I ask some questions to Samsung customer service Hong Kong, but I haven't got the answer yet.
If I do, I will post it here. cheers!

I have the China variant of the N9500 in Deep sea blue
I I've had it for 3 months with no problems. I saw from one of the other posts that there had been some issues they had found with theirs. Just to comment on mine Samsung pay initially wouldn't let me load a card and work but now it works fine with no issues. Google play was installed and works without issue also. Unfortunately I have not been able to get VoLTE or WiFi calling to work as the firmware installed does not support the former and the latter, I'm still trying to get to work, but neither I or EE can come up with a reason why it doesn't. I've also not been able to install a European /UK firmware due to the Exynos/qualcom incompatability issue. mind you there are only a few reasons why you'd want to install the firmware as the phone works fine with the firmware installed bar the issues I've mentioned and f you can live without WiFi calling or VoLTE then there's no reason to use it. They are a great bit of kit as I they come with a much larger internal storage than is available over here. This was the reason I got mine in the first place as I store loads of books and music as well as videos and as an amateur photographer alongside my DSLR I still use this for photos as the shots are quite comparable in lots of cases. I hope this has helped, oh and one more thing, I i got mine new from a online phone store via ebay I ended up paying about £750-800 for it which was cheaper than the lower storage version that you can get in the UK so that's another plus

No volte is a biggie for some.

i wonder if the wifi calling would work on the proper csc for n9500's or if like my provider, regardless of what mods are done to the phone's software, if its not a device purchased from them, they black list imei. well i should say they white list theirs and simply block everything else.
people on rooted 9500:
have you manualy extracted csc from relevant provider firmware and copyed to system/omc?

/ appreciate that it must a deal breaker for some out. there .I guess its just never been such a huge issue for me really. Its the inactive wifi calling that's the pain in the rear for me. It's not that
its not working that annoys me the most, its more
that there is no actual reason why it shouldn't work. that's the most annoying thing. its just so usefull to have.

Wi-Fi Calling and VoLTE on XZ3 Dual (H9436)

Hello everyone ?
Does anyone know of a way to get Wi-Fi calling and VoLTE loaded onto an unlocked, stock, non-rooted, H9436 ?.
PS: I know as a fact that my carrier supports both of them ?
Thank You

Only way is to use Xperifirm to download your regions firmware and flash it.
I know on my previous XZP I had a G8142 dual sim (Hong Kong) and flashed it a G8141 Single Sim (Australia) Firmware without any issues.
Unfortunately Sony Mobile has pulled out of Australia and there no Australian firmware for the XZ3. So I'll never get VoLTE on this phone now.

Did you see any battery life improvement since the second modem is not being used? ?
Is there no risk of bricking it?
It's gonna be horrible having all of my carriers crap on my phone
Maybe you could try using the firmware of another region that has it

XZP battery life became one of the best phones I've had after the last Oreo update. Since Pie it hasn't improved much. I would have the phone synced to my android watch all day. By the time i hit bed, i'd have 35% battery life left.
My current XZ3, would be dead by the time i get home from work, yet its supposed to have a bigger batter 3330mah vs 3230mah.
You dont have to use your specific carriers, just your country. Using the Generic Australian ROM I got VoLTE and VoWiFi working on Vodafone AU network.
At this current time no firmware is able to make VoLTE work on XZ3. Simply cause Sony Sucks now.
Might even sell this phone off or return it, as I've only had it a week.

Yeah battery life on this phone is just horrible
My mom has the XZP but she's stuck on Oreo cause Sony mobile abandoned the region, I'm planning on flashing a different region's firmware on my next trip home.
I thought of my carrier's firmware cause in France (my profile still says Lebanon cause I didn't bother changing, I moved to France a couple of months ago) the only unlocked version they sell is the dual sim one, the one sold by operators is the single sim one but they install their own firmware, and also because on their support website that mentioned that the xz3 that they sell is compatible with VoWiFi and VoLTE.
If you return it what would you get?

Well I haven't returned it, cause I still don't have my XZP back from warranty repairs. Appears Sony is abandoning alot of regions. Though they are still releasing updates for those phones which is a good thing.
I love Sony Xperia phones, by far the best quality handsets in terms of workmanship, etc. But how they go about their software implementations has a lot to desire.
Hoping one day Sony deploys Carrier integrations like alot of the smaller manufacturers i.e Asus, Huawei, Oppo and Nokia, who are able to enable VoLTE without any specific region firmware.

Yeah Xperia phone are really great, they have a mix of build quality and balance between software features and performance that just isn't available with other phones in the Android world (not talking about iPhones cause iOS is just BAD). I remember when I switched from my Z1 to a note 5, I was so disappointed. Wasn't sure if I wanted to get the Z5 or the note 5, so I decided to see why people praise Sammy, what a mistake ??*.
Going back to the main subject of this thread ?
I hadn't flashed my phone yet cause I had been pretty busy with school and wasn't sure if I should flash my carrier's firmware or not. So last week I got an update. A couple of hours later I went into the settings to tinker with stamina mode. And there I see it. A big banner on the top telling me to activate Wi-Fi Calling. So of course I did but couldn't test it directly cause I was out and about. When I got home (I have really bad reception in my dorm room, when people call me they go directly to voicemail cause I don't have any reception), I tried to see figure it out, but apparently it's just a placebo, it doesn't actually do anything ?
