I tried both manual flashing and flashing it through the app. When I do it manually I clear dalvic and cache and then flash it. When I try to reboot it just reboots over and over again. I tried all 4 Kernal from Kernal Manager but they all do the same thing. Also which one is the best? I really want to be able to Underclock to save some battery and also lower the minimum brightness. Thanks.
