Default [Q] I have 4.3 custom ROM, how do I install 4.3+ ROMs?

Hey guys,

my GN2 has 4.3 Alliance ROM atm.

I noticed that there are more 4.3+ ROMs available than 4.3 ROMs...

What do I need to do to install 4.3+ ROMs?

I think I had to unroot, install 4.3 Stock, then Jailbreak to go from 4.1.2 to 4.3.

Thanks in advance.
