I had my 900 for about 6 months working mildly flawless. Had a real 3.0 upgrade and everything was running smoothly. My bluetooth starting acting up so I wanted to reinstall the OS. As soon as I reverted back to 2.0 the start up splash screen wont leave and reboots after 2 min. I have tried multiple formats and 2.0, 2.006, 3.0, 3.1, installs as well as different maps. I have tried at least 10 installs win no different results. What am I missing here? Any help would be great.
