lost / prevail 2.3 friend rooted ctmod/ messed up

[markcap]

New here! Bought first smart phone 4 months ago, boost galaxy prevail 2.3.5 gingerbread, frustrated with no flash player working, let someone root a week ago, Ctmod. After hours of downloading apk apps, phone froze, rebooted, all downloaded apps are gone, and keeps signing me out of Gmail,
