No, can't say that I have, reason being I had not had to resort to such extents on previous upgrades. No warnings accompanied the upgrade instructions.

I too have a similar problem after upgrading to 2.0.3, immediately after upgrade reboot, I login to a blank GUI with only two options; infusions (which does nothing) and logout. I have absolutely no control. Thinking my device was bricked, I re-flashed to factory default, okay back online. So as a test, I upgraded again; got the exact same result, no control NONE. Ended up reloading factory default again, afraid to make any changes which will result in some more wasted time. I dread upgrades that cause more problems than they fix.
