I just bought a Galaxy S4 I9505. It was on 4.2.2 and I just flashed it to KitKat 4.4 (I9505XXUFNB9). But I just found out the Miui v5 ROM (here: http://forum.xda-developers.com/show....php?t=2657322) and I loved their theme (I would like to install iOS 7 theme).
Can I flash this ROM even if this MIUI version is based on Android 4.2.2 ? I heared that installing a ROM that doesn't support Knox while you were on a ROM that supported it is not so good for our Galaxy S4... So I prefer to ask, just in case.
