Unable to update iDrac 6 to 2.85

Hi all

As the title says. My first server I have done this on was at 1.8 for iDrac, I tried to update to 2.85 and after a long wait and a reset it did not change. I have since then applied 1.98 and this has worked a treat and it shows in the upgrade as completed and updated in the iDrac.

So I tried 2.85 again, but again it goes thru the upgrade but nothing happens it does not change...Its a

Dell R610, I have another 14 to do so want to get it right before I deploy the rest of them,

Any ideas?
