kitkat is bull****. no notification light, now screen doesn't even light up when I recieve a text.
If you download the latest version it's an executable so you don't need to decompress it with winrar.
Download Jellybean ftf's from here:
I've got kitkat myself and I have to say it works 100%, I have no bugs whatsoever, battery life excellent. I wiped my phone completely before upgrading to KitKat maybe that's the difference between bugs and no bugs.
