Updating from 2.0 RC1 to 2.2.6 - firmware upgrade fails

[bakerboy1977]

I am trying to update from a very old version (2.0-RC1) to 2.2.6.
The firmware upgrade just seems to hang.
Should I upgrade to another version first e.g. 2.1?
Thanks.

All fixed.
The problem was the laptop from which I was uploading the new firmware. Just after I posted this question - the hard drive started to make bad noises and crashed.
I uploaded the new firmware from another laptop and all is fine.
Cheers!
