why I can't flash a new ROM on my Nexus...?...I got root a couple nights ago and have been trying to flash a new ROM....BAMF...from WugFresh toolkit....everything seems to go well....but then it gets an error....and fails.....it says error proc.....and then it says sd-ext not found.....totally strange. However, I know flashing a ROM can be difficult....I'm just wondering why it gets this error....I even tried CM10.....same issue.....everything else.....from bricked...to custom recovery I've been able to do....what gives...?.....HELP........MDD
