My Sony Xperia S started rebooting after i installed Beats Audio Installation

I was looking through the Google Play Store after I rooted my Sony Xperia S The other day, and came upon the app "Beats Audio Installation" & Downloaded it and then when i opened the app and finished the setup, it started Rebooting and you cant go to your regular screen, etc. You can only see the boot loader (Green animated android logo) and Sony Logo in the beginning and it keeps rebooting. Please Help! Booting into safe mode using vol- when switched on doesn't work it still reboots as soon as it goes on. Any one had an issue regardless "Beats Audio Installation" please let me know how you fixed it.
