I also (now i know stupidly) tried to unistall power kernel via app manager, got message to say to uninstall need to use a seperate program, thought ok,will do it later, then was going bed so turned off phone, plugged it in to charge and it kept looping round on the first nokia screen vibrating once (as when you turn phone on) showing bright white nokia screnn and then looping again... am currently trying ot follow this to see if it works: http://discussions.europe.nokia.com/...LP/td-p/672328
