After playing around with this upgrade using the fortiexplorer application, I figure heck why not try via the WebGUI. I quickly found out the following;
- The upgrade is rejected with a "invalid image" via the WebGUI
- The image was compared by checksum and matches the md5 hash
- I re-downloaded the image a few times just for the heck of it
- a factoryreset made no difference
Here's some screen shots of this activities;
( The md5 hash comparison )
( FAP main page WebGUI )
( the start of the upgrade )
( immediate error )
note: The above upgrade process was done , both before and after a factory reset with no improvements
So it would seem like the FortiEplorer is not corrupting file during the upgrade. I have a email into fortinet support and a post on the support forum.
We will sit back and see what comes up. But using two methods for upgrading, all ends in a disaster. I have a few non-FAP28C models at some in-production site and I'm very hesitate to upgrade these.
My FAP28C is in a demo lab btw, so these problems don't really effect me.
