My S60 recently started malfunctioning. It looks like it's trying to start up with the blue orange triangle screen but it won't. I've tried to hard reset and turn it back on. Sometimes it does start up, but eventually it's go back into a reset loop out of nowhere. I've gotten to the settings one time before it looped and was able to restore defaults. That worked for less than 10 minutes and went back into a reset loop. Anyone else having this issue or have a fix?
