I´ve my TSU 9600 for only 5 days and now it´s completely frozen, showing only the initial Philips logo. It all started after starting a download and got a message that battery was too low to perform this action. After fully charging it all I get is this screen. Windows (XP, Vista and 7) do not recognize it at all. I can reset it and enter Full FW mode (Home+Menu+PG UP -> Firm keys 2+3+4). However FW Upgrade utility never enables Repair button. Any tip on how to proceeed before returning it ?
