Xperia SP does not turn on!

[menyus]

I did a backup and i wanted to refresh the software. The Sony PC Companion gave me error messages time after time so i unpluged my phone. It does not turn on, the PC fresher cant help. I tried the off button many times, it just vibrate and nothing happens. If i plug it in the wall adapter the notification led slowly flashing with green colour. The battery was about 70%. Any idea?

the battery wasn't discharged and i charged it but nothing happens. the green light is still flashing.

When i push the sleep button the led flash a very quick and nothing

try to simulate taking the battery out by using the off button depress it with a pencil or hair pin holding it down for about 8 secs , let it vibrate 3 times then try to restart the device

Ey guys i made it work! Restarted my computer, plugged the USB in the back of the computer, started the "reparation of the phone" without plugging the cabel into the phone. I just plugged the pfone in when it started to prepare the computer, and it worked. It reset the system.
