Trying to upgrade to ICS using the official update package from the Software Upgrade screen, I keep getting the message "The key data cannot be backed up. Thus, the upgrade cannot proceed."

When I use the powerup method pressing the volume control up/down it just says "Update failed" and stops on the first step.

I am using a U8800-51, currently running 2.3.5 and Stallion-51_ics with 404020 baseband.

I suspect it is something to do with partition sizes but not sure.

Any ideas guys?
