Why did my Logitech mouse or keyboard stop working and start blinking red and green during firmware update?

If your mouse or keyboard stops working during a firmware update and starts to blink repeatedly red and green, this means the firmware update has failed.

Use the instructions below to get the mouse or keyboard working again. After you download the firmware, select how your device is connected, either using the Logi Bolt receiver or Bluetooth and then follow the instructions.

For a list of Logitech devices this article applies to, please scroll to the end of this article.
