I am trying to upgrade the firmware on an old GX450 we had lying around for some lab testing. It is running v4.5.1 right now.

I started here: [AirLink GX450 Firmware Packages](https://source.sierrawireless.com/resources/airlink/software_downloads/gx450/gx450-firmware-list/) and was able to download v4.5.1 and v4.9.9 but when I click the link for the 4.9.6 intermediate version, it just gives me a 404 file not found. Every link I could find for 4.9.6 gave a 404.

Is there any way this can be fixed? Or is there some other way I can get the 4.9.6 file? Or is this router just stuck here?
