1. Upload and install the system recovery image to the router
2. Upload and install the main system image to the router.
Note: Do not interrupt the power during a remote firmware upgrade, as this may render the router unable to start up and will require a local system recovery upload to be
performed.
You can do this by clicking on the browse button and then to navigate to where the recovery image upgrade file is located on
your computer
Once you have selected the recovery image file to use, click Upload to upload the file. You will then see a progress bar as shown in the
screenshot below. The upload has finished when the status bar reaches 100% and the "Phase:" has changed to Complete.
When the upload has completed, the screen should refresh and list the file you have just uploaded. Click on the "Install" link to the right
of this.
Once you see "Done" shown as per the screenshot below,
Click on the browse button again and navigate to where the main system image upgrade file is located on your computer
