Rooted Samsung Galace2 won't go into recovery

A

AC Question

I like the size and function of the Samsung Galaxy Ace II so I recently rooted it so I could remove the bloatware. Phone works fine most of the time but then it has MONUMENTAL lags when that take 1-2 minutes to access my camera, or dialer.

I want to wipe the hold cache partition but when I hold the "Home"+"Volume Up"+"Power" button I just get a black screen. If I let go of the power button the phone starts up normally.

Any thoughts on how I wipe the phone? Cheers!
