I have updated my GT-I9500 (S4 Exynos version) to the official TouchWiz 5.0.1 ROM (I9500XXUHOC1), but ever since this update the phone gets heated up during usage and especially during charging (which is high than what it use to be earlier). Am getting frequent force close messages (some which were fixed with a recent OTA update) but still the experience has been horrible with the official Samsung Lollipop uddate. I have now rooted and got Philz Touch Recovery in place. All I wanted to find out is can I wipe and flash CM11 (GT-I9500 Version) on my device, will it work or will that brick the device as am directly downgrading from 5.0.1 to 4.4.2 ? Is there a specific way to do this ? Any help is very much appreciated, I need to get out of this 5.0.2 for good.
