Toshiba e-STUDIO556 Service Manual page 905

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. In this case,
shut down the equipment after all the updates are stopped (when either "Completed" or
"Failed" is displayed for each item), and then check the following.
- Do the USB media meet the conditions to be used for updating?
- Is the data file written properly on the USB media?
- Are the USB media installed properly?
- Do the USB media 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 the following, and reperform the
update.
- Check that the firmware data is not corrupted.
- Check that the signature file is not corrupted.
- Check that the combination of the firmware data and the signature file is correct.
• When an error occurred and the update failed, "Update Failed" or "Failed" appears on the
screen and an error code appears next to the message. The content of each error code is
shown below.
