[Q] Rear camera not working after installing CM 10.2

Hi!

First of all, sorry if I have some error on my writing, it is not my first language.
In addition, I'm a newbie in this matter, sorry if this is a stupid error/question.

Well, the scenario is as follows:

The device is a Galaxy Note GT-N7000 from Claro (Argentina)
I had the original JB 4.1.2 (Stock - it is the newest version available for this phone/carrier).
I successfully followed all CyanogenMod Installer steps and now I have CM 10.2 on my phone.

The only thing that is not working fine is the main (rear) camera.
Front camera is working, but if I change to rear camera there is no image.
If I try to take a picture with the rear camera the app closes and the following error is showed: "Unfortunately, Gallery has stopped.".
I did a factory reset using TWRP and nothing changed.

The front camera works just fine.
The rear camera was working with the stock JB.

I guess (hope) this is a sw issue...

Any idea of what can I try?

Thanks in advance.
