I tried to upgrade to 2.1 with official LG update but it just got stuck midway so I unplugged the USB cable. When I restarted it just kept freezing on the android screen. Then I read some posts and used the KDZ Updater in emergency mode. Everything went OK and I restarted the phone. Now when I press the power button, it just vibrates and nothing else happens. Any ideas on how to get out of this mess? Thanks.
