well i'd guess that if you you switch from 1.5 to 2.1 or vice versa that should do it..not sure bout the downgrade but i know if u upgrade from cupcake (1.5) you will lose root (but if your trying to regain your warranty im quite positive they can still tell its been tampered with) HOPE THIS HELPS!

Rooting it voids your warranty?? That's ridiculous. Rooting in ubuntu or using Admin access on Windows doesn't void the software warranty..
