at random times during the day. Just started a day or so ago. I have to pull battery to get it back on. loaded different ROM and it still does it. Probably happened 5 times today.
Are you saying when you press the power button, the screen doesn't turn on and you have to pull the battery to bring it back to normal? If that's what you're talking about, then what I did to fix that problem was cranking up the clock speed to at least 600mhz min. It sounds like it will drain the battery but I've noticed it doesn't even appear to have an impact on battery.
