I ran into the white screen problem last. My device was loaded with firmware labeled S10_07_04B...... The version on the website appears to be newer S10_07_04K... so I upgraded. After the initial upgrade I starting seeing the error message on the home screen. After rebooting a few times the screen turned white. I was able to recover by resetting the device using the reset button. I upgraded again and it seems to be working fine.What's the version number of the most recent firmware and where can I get it if it's not on their website yet?
