When your phone boots, do you see the blue led ?

If yes, means you still have the recovery on it.

If that's the case then download some other rom and flash it again.

In case the above is not true, you're left with no other opton but to use flashtool.

Make sure your phone is off while you connect it ( take the battery out and then insert it , then do no switch it on but connect to flashtool ) and you have the proper flashmode drivers installed.

C;/ drive > flashtool > drivers > install > mark flashmode drivers and xperia arc s drivers > install.
