On this live website, I'm trying to get previous versions of Firmware for a camera lens. The companies' support generally ignores you, so I was seeing if I could figure out a workaround lol.
AF 135mm F1.8 FE is on version 5 of the firmware. I'm attempting to get version 4 and version 3.
If I inspect it, the button click triggers the following onclick function:
<button type="button" class="bt-full black" onclick="FnFileDownload('964','5');">Download</button>
I've tried modifying the DOM through inspector, swapping out to
<button type="button" class="bt-full black" onclick="FnFileDownload('964','4');">Download</button>
But no luck, it still pulls version 5. I was thinking, if I ran something through the console, maybe it would be possible?

Turns out the server always returns the v5 of the firmware, not a JS related issue. It's the file that's available for downloading.
