Quick question, if I root and say I want to flash zip packages for things like Google now or some zip files like beats audio for example, would I need safestrap or bootstrap to flash the zip? And would I be able to flash those zip files on stock? And , although I don't think I'll do it, I will need the kexec kernel to over clock right? Also, to unroot using Matt's utility I just flash the ap fastboot option which is unrooted? Lastly, how would you remove a custom recovery? Sorry for the long post. Thanks
