How do I recompile Android 4.2 firmware

[jnadnotlek]

I have my firmware decompiled and I made a few changes and now I'd like to recompile it and sign it, but I'm lost as to how to get this done and it work. I can do apks just fine. Don't laugh, I'm new at this and I really want to learn Android OS. Any help would be appreciated. Thank you.

An apk file is just a zip file with the extension changed to apk. Does that help you?
