Toshiba e-STUDIO 2555C Service Manual page 996

Notes:
• "Update Failed." is displayed at the bottom of the LCD screen when the updating is not
completed properly. "Failed" appears next to the failed item on the status display. Even
though an update fails, do not turn the power OFF until other updates are finished. If "Update
Failed" appears at the bottom of the screen, turn OFF the power and then check the following
items. After confirming and clearing the problems, restart updating from the beginning.
- Does the USB device meet the conditions to be used for updating?
- Is the data file written properly on the USB device?
- Is the USB device installed properly?
- Do the USB device and equipment operate properly?
• The integrity check system is automatically operated before firmware updating. During this
operation, "Verifying Signature..." and "Progress: **%" are displayed on the control panel.
When the check is completed properly, no message for notifying the success will appear and
the firmware updating will start. If it fails, "Invalid Signature" and "Copy Data with >valid
signature in USB" will be shown. In that case, firmware updating cannot be performed, so turn
the power OFF and disconnect the USB device. Check that there is no abnormality in the
firmware data, and reperform the update.
• When an system firmware (OS Data) update error or system software (HD Data) update error
occurs, "Update Failed" or "Failed" appears on the screen and the error number appears next
to the message.
