When an automatic firmware update cannot finish

1. Check the connection

   Connect directly to the computer with a known working data cable where the device uses one. Avoid a hub during troubleshooting. Keep the connection steady throughout an update.

2. Check the download

   An update needs access to the firmware download as well as the device. Note any network, download, device-detection or file-write error rather than treating every failure as a permission problem.

3. Check removable-storage access

   The supported device appears temporarily as a USB storage volume during flashing. A policy that blocks writing to removable storage can stop the update even if ordinary mute control works.

Ask IT whether writing to the device’s temporary firmware volume is permitted. MuteMe checks some Windows policy locations and macOS configuration information, but those checks cannot detect every restriction.

Do not disable System Integrity Protection, antivirus or managed-device policies to follow this guide. If your organization permits it, use an approved computer that can write to the device, or have IT supervise the update. Erasing firmware does not bypass a USB storage restriction.

If macOS asks to allow MuteMe access to a removable volume during the update, review and allow that specific request if permitted on your computer. On a Mac that asks whether to connect a USB accessory, approving that connection is separate from allowing a firmware file to be written.

If you see a temporary bootloader drive after failure, follow the recovery guide before taking another action.

The failure prompt may offer Disable Firmware Updates. You can also open Tools and turn off Firmware Updates; older guides call the area Diagnostic Tools. Re-enable it after the connection or policy issue is resolved. This preference is separate from app software updates.
