So I want to go ahead and try one of these ULV kernels. It seems everyone who uses one, has very good battery life. But with these ULV kernels, runs the possibility of the phone not booting up. If I install one of these, an this happens, do I take my sd card out of my phone an manually hook it up to my computer an put a different kernel on an then boot into recovery an install the kernel that way? I want to make sure I get this right, the thought of my phone not booting up makes me nervous. Or is there another way to fix this if this happens?
