I tried to flash again, but this time I waited after the beep when rebooting, after 20 sec a grey screen has appeared with apple's logo and a charge bar . It was similar to this image (http://www.askdavetaylor.com/0-blog-pics/apple-bootcamp-photo1.png). But two seconds later the screen turned black and nothing happened.
This happened in the last 14 boots in the 15-16th the computer started up like always.
