"Thank you for requesting information from your TrekStor Service Team.

The reason for the described malfunction may be a damaged firmware. We recommend to reinstall the current firmware on your i.Beat mood. You can download the firmware for the i.Beat mood from our web sites at http://www.TrekStor.de/en/index.php. Choose "Service" and then your MP3 player.

Please note that the firmware can only be reinstalled using a Windows operating system. The files which are downloadable on our web sites are packed and in ZIP format. You will need archive software as e.g WinZIP to open and extract this file. If you do not have a suitable programme installed on your computer you can download it as shareware from the internet.

Install the downloaded firmware on your PC by double-clicking the file "Setup.exe". Start the firmware update tool afterwards. Remove the battery of the i.Beat mood. Press the MP3 player's Play button for approximately five seconds. Now connect your i.Beat mood with still pressed Play button to your computer. Keep this button pressed until Windows detects a new device in recovery mode.

After your computer has installed the i.Beat mood the firmware update tool will detect your MP3 player. Now you will see the recent (current) and the new (update) firmware version. If "Format Data Area" contains a checkmark the i.Beat mood will be formatted before the update and all data stored on it will be deleted. TrekStor advises to format the i.Beat mood along with every firmware update.

Afterwards, your i.Beat mood can be handled as usual. Moreover the MP3 player should be accessible again under My Computer.

We know that you as a customer have the choice and we thank you for having decided for TrekStor."
