The update may have failed due to the dropped connection. Try connecting again and checking the status. If the update failed, follow the instructions below to restore the firmware.
<Restoring the firmware over a wired connection>
Make sure to use either SM-PCE02 or SM-PCE1 updated to the latest firmware. (These are the only PC linkage devices that have a restore function.)
For information on how to confirm and update the firmware version, refer to the "Firmware Update" section in the Help Manual (General) found at the URL below.
The firmware can only be restored using a single unit connection (refer to "What is a single unit connection?").Follow the instructions on the screen to use SM-PCE02 or SM-PCE1 to make a single unit connection, and then restore the firmware.
If you do not have one of the above PC linkage devices, please contact the dealer from which the bicycle was purchased.
* Some products may require selecting the model name to restore the firmware. If you select the wrong model and then restore the firmware, the unit may become unusable. Ensure you select the correct model name
