Hay dos versiones de firmware segun la zona (UMS o MTP), si actualizas con un firmware del tipo UMS cuando lo conectes al puerto USB funcionara como si fuera un disco duro (por ejemplo en Australia se utiliza el firmware UMS). Si te quedas con el MTP (Europa y USA) entonces estas obligado a Windows Media Player 10, DRM (y windows XP), y demas incomodidades.

Instrucciones de como poner un firmware UMS:
1. Download, unzip and rename the HEX file to T30_MPURE.HEX for Pure or T30_MTP.HEX for Non-Pure devices.
2. Plug in your T30 to the USB port and copy the file using Windows Explorer to the Data folder on the device.
3. Wait until the device stops displaying the Transferring data… message, then remove it from USB.
4. Your T30 will now restart and flash the new UMS firmware, it will then turn off. Be patient, it takes at least a minute or two...
5. Using your T30 go to Settings -> Advanced -> Format and format the player.
6. Now everything should work correctly. Plug it into a USB port and it should be detected as a USB Mass Storage Device.

PURE = SIN RADIO
NON PURE = CON RADIO
