C6903 ROMs are NOT usable with the C6902.
You need to get a ROM specific for the C6902.

Yes.
(There are small differences in radio hardware between the C6902 and the C6903, which is why the software is not exchangable)

I'm not familiar with the differences between the XZ models (I'm on a Sammy GS2 atm). But the fact that crossflashing works for the XZ, doesn't mean it will work for the XZ1; for example, I can't flash i9100g ROMs on my GS2, because even though they are the same model, the internals are different (though the GS2 example is an extreme case).
Of course you are free to try crossflashing the C6902/C6903. Perhaps you won't break much, but you'll probably won't have a working radio (in other words: no calls, no texts, no data). Or you might brick the device entirely.
Personally, with such an expensive device as the XZ1, I wouldn't risk it and stick to C6902 ROMs until we (=the community) know more about the devices.

I have a 6606 and I flashed a 6603 Spain. Everything worked as it should. I then flashed 6603 Belgium to the newest one .244 and its awesome. If you want to tether, you need to wipe data via the flashtool. You can still back-up/restore using Sony pc companion.

I followed the Instructions made sure I put the zip on internal memory not SD card.
So...what is the advantage of flashing another stock rom from another region. I dont understand the difference between the stock rom I allready have and the other various stock roms available here.

Because for example I flashed the newest 4.2 firmware that was just released yesterday I only used Spain because it was the newest now my stock ROM is light years behind gawd its still 4.1
Sent from my C6603 using xda premium
There are just 3variants samsung also have them but names them differently or sometimes same with different model number example S4 i.e i9500 & i9505
Anyways there are 3 variants i guess of XZ
C6602: Hspa+ model
C6603: lte model
C6606: tmobile version
You can flash any firmware on any device it will be just that you will miss functionality of lte if you flash c6602 etc i hope thats simple enough

Does c6902 have better battery life than c6903/c6906 because lack of LTE?

no. it depends on how you use the phone in my opinion. C6903 may have LTE radios, but you can turn them off by selecting WDMA/GSM in the options or GSM only. that way, LTE radio is not active, therefore having the same battery life. Also, i don't know if LTE eats more battery than HSDPA. never tried it. never will. lol.
P.S. I have C6903

The main difference between them is C6903 is LTE and could support 4G, but C6902 is +HSPA and just can support till 3G
But C6902 has more 3G antennas than C6903, and so it will be better if you wanna use 3G sim in the best way and best antenna signals
Have fun
regarding the firmware,
is the kernel different between them all (C6902/3/6)
or is all the same kernel, regardless

Have u got the sources for where it says that the kernels are the same?
I think the kernels or some components of the rom do have some small differences because you have to flash something extra on the c6902 to get custom roms to work on it.But the hardware is identical except for a different baseband modem(for LTE).

If you mean Writing Language, all Roms have the same languages for writing, and there's no difference between Roms in this case
But if you mean the Phone and Menus language, you can search how to add Arabic language to your phone
I saw something like this that did not need Root, but it was for Farsi language
Search Arabic "adding Arabic to Z1"
If there was no good title, search English

Only Sony and/or your provider can confirm that, but even then it would be nice if you could tell us what version are you on now? You don't even tell us that so how are we meant to help you......

Why don't you just use Flashtool to get it to your phone using one of the available ftf's ?
Here is a video on how to do that:

Flashing with flashtool don't need root acces and it can't be detected.
You have to read before ask,you will have a reponse faster.
Read that ,if your Z1 is not on the list wait a week or two or flash with Flashtool
I would update through the PC companion. Many people seem to have encountered problems flashing with flashtool on this update. It was taking forever for the ota for me as well

When the Z1 first announcement it come with 4.2.2 already. So if he ask for 4.3 or 4.4 that meant he on 4.2.2 already.

Whether you use UK generic or any other generic one does not make a difference whatsoever, but it's up to you.
I have never encountered any problems when using Flashtool. Just make sure to use the most recent version.
The 4.3 is avaliable so if you use OTA or SEUS you get it.
As for rooting, it doesnt avoid your warranty unless you remove the root and install a clean version when you deliver the device for repair or replace it.
Only thing that avoid the warranty is unlocking the bootloader.
Keep your .257 rooted version and wait for a rooted locked version for 4.3.
Btw there will come a hotfix version in January (newer 4.3) for Z1.
4.4 will come April/May i think...

Nah, every firmware has a slightly different. Australian firmware is specially designed for Australia. Therefore you should flash aus tft

I tend to agree with you otherwise why do Sony have so many different (counrty) versions.
You would'nt by chanch have 108.ftf ?
The differnces are either cosmetic or include/do not include certain apps to apply with local legislation. It also helps deliver updates on a global scale without everyone downloading at the same time. They can stagger the release. It makes sense to do this for many reasons.
All this makes no difference to phone performance. You can flash any regions FTF as long as its for your device (C6903 etc)

[Q] Will C6603 or C6616 ROMS work on a C6606?

I see very few roms that explicitly say that they support the US TMob C6606 phone but the different devices are almost identical. Can someone tell me what to expect in terms of compatibility if I try flashing roms from C6603 or C6616 to my C6606?
hope this helps
