ZTE Nubia Z9 Mini (NX511j) - Cam driver for international Version

Hey all,

the problme is that the international version has another cam module (13mp) than the chinese version (18mp).

Therefore the custom roms , which are always based on the chinese version and cant use the camera.

Now I need some help on how to implement the driver from the original firmware:

Into this custom rom from mokee:

My phone is already rooted and has a custom reovery. I already tried to "zip-edit" the mokee rom and copied/replaced files from the stock rom into the mokee rom , base on this info from here and here e.g.:

Libcamalgo.so
Libcameracustom.so
Libcameraclient.so
Libcameraservice.so
Libcamerametadata.so

and

system/lib/ libcamdrv.so
system/lib/libcamalgo.so
system/lib/libcameracustom.so
system/lib/libdpframework.so
system\etc\permissions\android.hardware.camera.xml

and then rezipped the rom and signed the zip with the autosign tool.

This "custom" rom than could even be successfuly installed with twrp without an problem, but then didnt
get beyond the mokee boot logo.

Now my question is:

Can this be due to the fact that the stock rom is 5.02 and the custom rom/mokee is 6.01 and the drivers simply cant work due to another android version?

Am I thinking way to easy with this simple "copy/paste zip editing" and something more complex like editing the kernel has to be done?

Any tip for what to do is very appreciated, as I think I have to solve it by myself due to a lack of mass-interest in this device.
