Manually Updating the firmware on your My Cloud PR4100

Important: Make sure you stop all processes and save all your data before performing the firmware update.

Note: My Cloud devices require a hard drive inserted into the bay and a volume must be created to perform the firmware update.
Do not interrupt the firmware upgrade process. Doing so may cause the device to malfunction or unable to boot.
If you are using the manual update method, do not rename the firmware file. Doing so will cause the manual update to fail and can corrupt the system.
