[Help] Unusable touchscreen&backlit buttons after installed app topic

My phone is Samsung Galaxy Pop (SHV-E220S). I downloaded this app "Advanced Battery Calibrator",then Celibrated following instructions. It forced my phone turn off. I charged it (full battery) then turned it on. My touchscreen doesn't react with any impact, and backlit buttons (left and right Home button) dont either.
Sorry for my bad english, I hope you guys can understand and help me fix this problem. Thank you very much.
