I updated the same way to 1.2.8 and older before.

Now the camera is "dead" with only green light visible.

I've tried waiting 2+ hours, only remedy is to shut down the power, it wakes up and works normally, but still on 1.2.8.

I've also tried formatting my SD Card, no change.

Sometimes it says "Installing..." sometimes "Updating..."

Anybody encountering the same behavior?
