Default [Q] Xperia p boot screen loading...

I flashed the JB latest stock firmware which i downloaded from here, http://xperiafirmware.com/8-firmware...-xperia-p-lt22 , using flashtool, i unchecked data, and did not check 'no final verification'. The flashing completed but after i flashed, when i turn on my phone, the boot screen just keeps loading on forever. Also i did not enable USB debugging cuz i forgot... My phone is bootloader unlocked.

Can someone help me?
