OK. Since u aren't sure either, I jus installed Coderus aegis-install from ur N9QT tweak EE-2 (probably installed over an already existing package given that I'd previously tapped 'n installed the deb file via file manager).

How do I revert this change if 'n when I want to?

Also, my queries are yet unanswered . I'm really findin' it very difficult to understand many things despite tryin' hard. I need some help here pleeease
