if you have no backup to install (always make backups before something like this happens!)
you have to reset your phone
if you have a recovery installed you can still make a nandroid backup of your boot-looping phone
this way you can restore important apps with the app Titanium Backup later (from the nandroid backup)
costs around 5 bucks, depends on how important your data is to you (if you haven't bought it already )
should work, but I can't guarantee you anything
and in the future: always read the root app`s descriptions and always make a backup before using it!
