Trackpad firmware update

[inkslinger]

It was the second part that doesn't download /  work. It says something like saying, file can't be found.

I had a similar issue. I rebooted and started with Step 1 again. I had to do it a couple of times, but it eventually worked. Not sure why it doesn't consistently work on the first try, but others have said they had to do it a few times to get it to work.
