Hello to everyone! :) First of all, I apologize as I know this isn't the right sub-forum for the products I'm talking about but I've had no choice because one for the 13 lite or the Civi 2 doesn't exist.
I own a Xiaomi 13 lite and Xiaomi.eu is going to make a new release for it any soon so no issues for me but I was talking with a main developer along with other owners here.
I was confident the 13 lite and the Civi 2 were EXACTLY the same thing, just for different markets but this turned out not to be the case. Indeed, they are almost the same but not completely being the cameras different.
Apart from being very helpful and giving me a much better insight on how things really are, the main developer has clearly stated that Xiaomi.eu isn't goiing to deal with the Civi 2 (and I completely understand the reasons for such a statement) but I've been intrigued at the idea of a Civi 2 owner (not my case then but, for example, the one of Barb0ne there and I believe not only him) being able to take the 13 Lite Xiaomi.eu and just 'swap' the camera subsystem.
I can think about at least a couple of big reasons leading to Xiaomi.eu not doing that even if it was so plain simple (like I think it actually isn't) but what if a Civi 2 owner tries it by himself?
I know the camera subystem should be embedded inside the kernel so it is quite hard to deal with it (I can only think about rebuilding it from scratch), even on rooted phones. Maybe using modules but I don't know... I haven't the knowledge needed to have a better insight.
For example, I think that taking a Civi 2 official Xiaomi CN rom and getting the kernel from there then swap it with the Xiaomi.eu 13 Lite one is a complete nonsense and could only lead to bootloops or worse. Has anything like that ever been done? I'm very curious about that and that's clear the question is mainly for developers. Thanks for your opinions (if any) and a nice day to everyone out there. :)

Weird since there are common global versions.
Xiaomi Civi 2/13 Lite Global Stable Fastboot V14.0.1.0.SLLMIXM 12.0 6.9 GB 2023-01-10.

Which would mean that there is a Xiaomi civi 2 in global version since we cannot lock the bootloader on a CN version with a Global rom.

Thanks for your follow-up. I don't know what to say: you're absolutely right that there on XiaomiFirmware it seems let's say 'unified' roms are available but this goes in contrast with what that main developer was saying on the thread I've linked above and this is rather strange.
I tend to give more and more credit to advices coming from him rather than a (very well done and useful but still automatically generated) site. As already explained, I own a 13 lite so I can't check by myself. Maybe Barb0ne would like to. Thanks and have a nice day! :)

the roms are recovered from the official Xiaomi servers, you can check the MD5 which will be identical.
It may be an error from Xiaomi, it wouldn't be the first time.

Saying anything wrong against XiaomiFirmware wasn't my intention, not at all and I'd like to underline once more as I've already tried to in my previous message. I'm starting to think that Xiaomi could well manufacture two lines for the Civi 2: the global which is just a rebadged 13 Lite and the CN which has the different cameras. It could be an explanation (but a mess apart from a nonsense from Xiaomi; not the first time anyway, at least if I remember well).

I tried all the roms in both global and EEU versions the problem is always the same the camera app crashes, it is partially solved by installing a third-party camera app (it works partially, the main camera works but when you activate the secondary for selfies not working properly)

See here, sold with the global rom with the unlocked bootloader.
Edit:
It's exactly the same problem as with the Xiaomi 12T Pro and Redmi K50 Ultra, same phone but completely different camera (not the case with the 13 lite and civi 2) and yet Xiaomi Eu exists for these phones.
In fact, from the site it may seem that there is a common rom, it would be necessary to have and test it, to see the effective functioning.

Not a complaint, we've put here relevant informations anyway but my original question (and the meaning for such a thread being opened here on a developer's forum) has been slightly sidelined... :( That's a pity, at least for me. I'd prefer to receive at least something like a reply saying "Forget it, it is impossible to do!" (like probably it is the case) rather than nothing at all.

I saw the answer, that does not explain why there are common roms.

Also tried the latest official global ROM 14.0.4.0 (some sites specified that it was compatible with the Chinese CIVI 2 version) but in fact it is not compatible. I deduce that for european owners of CIVI 2 China, the only possibility is a developer who works on the Chinese rom possibly adding European languages, which I don't know the level of difficulty.
