Upgrading from 4.0.4 to jelly bean

[csteotico]

Hi. I've had a Samsung note for over a year now. Since it was a secondary unit, I hardly used it until now. I have the first version (note1) and my OS is still on 4.0.4. I was wondering how I can upgrade to the jellybean? Is there an online tutorial for that or a site to download the new OS? I checked online but it was upgrading from a 4.1 already which I still am not using.

Hope someone can help. Thanks
