will this erase everything? i'm in the same sort of boat... followed the instructions here: http://geekfor.me/faq/how-to-root-th...c-sprint-hero/
and got to step 10 where it says it boots into recovery mode. unfortunately, it just freezes the phone at the initial HTC logo indefinitely (i gave it at least 45 minutes).
so i kind of want to start all over and unroot and begin again, but i'm hoping it doesn't completely wipe all my settings/apps etc...
edit, just ran the update utility and now see the bright red caution saying it will delete all info and data...
anyway to undo steps 1-9 from that instructions without running this utility?
