OK already did that Altboot, and follor the instructions:
1. Turn the WorkCentre 3655 power Off.
2. Insert the prepared USB thumb drive in the USB Port on the left side USB port (left side as you face the WC3655).
3. Turn the WorkCentre 3655 power On.
4. The Control Panel will display the current state of the upgrade process.
5. After the firmware update process is complete, the control panel displays a prompt to remove the USB thumb drive and to “Press the 0 key”. Remove the USB pen driver and then press the “0” key.
6. Wait for the WorkCentre 3655 to reboot and return to Ready.
