Unless somebody that is using the firmware comes along and helps you, I would suggest extracting the build.prop from an O2 Germany FTF with Flashtool and something like Diskinternals Linux Reader and checking the value.

Differences between Official and Commercial&Journalists

For those wondering about the differences between the C&J rom and the official ones available at the moment...

In short:

Not worth changing, contents are the same for pretty much all purposes (except customization numbers)

Differences between 10.4.B.0.569 "

Commercial & Journalists

" and "

Generic CH

" (1270-6188)

System Apps removed in Generic CH:

- Google Play Music (available in the store: link)

- Sony Reader (available in the store: link)

- Sony Entertainment Network - Account Manager (available in the store: link)

Other apps also removed (from /system/etc/product/applications/)

- Playstation Mobile (psmplaceholder.apk)

- Sony Video Unlimited (SnpVUStore.apk, available in store: link)

Customization settings:

- /system/etc/customization/settings/config.prop has "ro.telephony.default_network=9" (not sure if relevant for Switzerland)

Overlay resouces (/system/vendor/overlay):

- Generic CH has additional stuff, mostly Sony default bookmarks for the browser

Customization values in /system/build.prop

elabel-* partition contents (legal info only)

Everything else (bootloader, modem, etc.) is

exactly

the same.

I didn't compare any of the other .569 versions for other operators, but the results should be the same.

[Xperia Z General] Apollo89:
I believe the update server is caching the results for each URL. If you checked with Sony PC Companion shortly before the update was released, it might take some time before the server cache gets updated. You'll have to wait a bit or use Sony Update Service, which uses a different system to check for updates.
[Xperia Z General] tseyksuli:
it usually takes up to 1 hour before Sony PC Companion will detect new update.
[Xperia Z General] Apollo89:
Only if there is an old result of the update check in the server cache. If not, it will detect the update immediately. The Browser Bookmark URLs in post #1 are the same URLs that are being used by Sony PC Companion to check for updates, but some of the parameters will be different, so that's why you may get a different (cached) result.
[Xperia Z General] tseyksuli:
not really once firmware was latest on firmware site and firmware customization number, then Sony PC Companion didnt detect it untill 1 hour later then it said new update available.

Since i keept pressing check for update part all the time and it keept saying my device is up to date but even i checked firmware customization number 1270-7280 it said it was etc 10.4.B.0.569 but still program said my device was up to date, so it actually does take around 1 hour before Sony PC Companion detects the update.

Unless you meant that Sony PC Companion method uses cache like you mentioned earlier?
[Xperia Z General] Apollo89:
That's what I'm saying. If you check with Sony PC Companion before the update is available, that result stays in server cache for a while. If the update then becomes available and you check with Sony PC Companion again, the server doesn't perform a real update check but just sends the old cached result again. It takes some time before old results get cleared from server cache.

Hi,

Does anyone know the SI-Numbers for:

Generic AT (Austria)

Generic World

If not,

Whats the "best" SI number for Austria? (Currently I'm on Austria-Mobilkom A1). Which "CE"-Version would be appropiate?

What's the difference between CE1,2,4 and 5?

Thank you
[Xperia Z General] rayblo:
which codes can be used in Netherlands?

Generic CE1 1270-7298 10.1.1.A.1.253 Central Europe 1

Generic CE5 1273-8577 10.1.1.A.1.253 Central Europe 5

Searched but cant find this out :p
[Xperia Z General] Apollo89:
What do you need the SI number for?

SI numbers can be found in these lists:

[INFO] Xperia Z firmware customizations (region/branding) and SI numbers

Generic AT and Generic World does not exist.

You can use any customization you like, they work on all networks, in all countries and they contain all languages.

The only difference is the pre-installed apps, some small details (like NFC logo) and sometimes operator logos in the branded versions.

Just pick one of the customizations with the latest version (10.3.A.0.423), like 'Generic ES'.

Which customization are you currently using? Why do you want 'Central Europe'? For the Netherlands, there is 'Generic NL'.

But like I said, you can use any customization, so just take one with the latest version (10.3.A.0.423), this is Android 4.2.2.
[Xperia Z General] rayblo:
I'm using the Generic NL code :) but i will wait till this version comes by
[Xperia Z General] Apollo89:
Unfortunately, 'Generic NL' is still two versions behind. It can take a couple of weeks before it gets updated.

Is your phone currently rooted? If it is, you can easily change your customization number to 1270-6697 (Generic ES). After that, you'll be able to update using Sony PC Companion / Sony Update Service. See part A of this guide:

[GUIDE] Download ANY firmware customization from Sony & create an FTF with Flashtool

Otherwise you can also flash this FTF without wiping DATA and CACHE:

Hello everyone!

Is there anyway to download Stock firmwares manually from somewhere?

I have Xperia Z bought from NL and i live in finland so i would like to try:

Finland Elisa FI 1270-9870 10.4.B.0.569 R2C

But ofcourse i can't download it using sony's official tools because they always install latest NL version which is still 4.2.2
[Xperia Z General] Apollo89:
There are two possibilities:

1. Downloading and flashing an FTF file (if available). This doesn't have to be the most recent version: if you flash an old Elise FI firmware, you will be able to update it to the most recent version via any of the official channels.

2. Rooting your phone temporary (without bootloader unlock!) and following this guide to change the customization number to 1270-9870. After that, you will be able to update to the latest Elisa FI firmware using Sony PC Companion/Sony Update Service/Sony Bridge for Mac (which will also remove the root again).

Sony jokes

Sony mocks with their customers ... I do not understand why so many customization invented, instead of creating one international version of generic rom.

all the time on the 4.2 android. (CENTRAL EUROPE 1 GENERIC).

I'm starting to think seriously about changing my phone brand ...
[Xperia Z General] Apollo89:
This allows them to include region specific apps and carrier settings. For example, Video Unlimited and PlayStation Mobile are only included in regions where they are supported. It also allows them to keep server load under control by employing a phased roll out. Although one can argue that if Apple can release iOS updates for nearly all their devices worldwide at the same time, Sony should be able to release updates for at least only one of their devices worldwide at the same time (especially the generic firmwares, carrier branded firmwares would better not exist at all).
[Xperia Z General] rzuku90:
exactly what I mean. It should be like in the case of the iPhone.

During the software update, just after you turn on your phone and selecting a region, the device should install the needed applications.
[Xperia Z General] TitchyPenguin:
This. Apple is slightly different though due to it's control of iOS, it just doesn't release an update until it's available to every device. Which realistically just delays some people getting it.

You have to remember that Sony wants these updates out asap. They have no reason to delay it and want to keep customers happy. So there are probably more reasons than we consider.

i may know now what happens if you flash preset1.ta and don't exclude it.

As you now i acciendally flashed the preset1.ta.

I relocked the bootloader and unlocked it for curiousity.

And i saw that i needed to type the command twice, the first time it failed to unlock, even though i entered everything correct.

But after it should be unlocked, i saw it wasn't.

I couldn't flash a custom boot image via fastboot.

Next i tried flashtool. And it stated that the bootloader wasn't unlocked, even though it should be unlocked.

After unlocking with flashtool everything works now.

The preset1.ta may change some files in TA-Partition i guess.

I haven't notice anything different as I included preset1.ta when I flashed. And I rooted using DoomLords advanced stock kernel after unlocking bootloader and successfully restored my old TA backup without any problem :) but I used the flashtool to unlock it instead of manually typing on fastboot mode

Only US model received 4.4, but you're right, what Sony is doing with their Si's is completely their own way of doing it. Backing up largest markets for the last part is safe but not when generic receive update 1month after branded one.

Standard update process is here

In short, either flash one of the generic FTFs available to download or just wait quietly like everybody else, because nobody cares.
