Since the mission of XDA Assist is to provide basic help to those who have tried searching but can't find what they are looking for and need assistance.
Please remember this is not a "helpdesk" providing technical assistance but more to point you in the correct direction with your problem.
And regarded to last thing, you already pointed in the right direction from my colleague @PulseDroid here
and you already opened a thread in the correct forum here: [Q] How to Upgrade Android Version
But, for better response, try to read all threads ROMs you are interested and put/post/ask questions where you doubt exactly.
