Help needed!

So a friend of mine has Xperia s..
he has usb issues(it doesnt get connected to pc in any way..motherboard issue)
so he was on 4.1.2 with locked bootloader..

he rooted via kingsroot..
then he installed cwm via http://forum.xda-developers.com/xper...evice-t2877774 this method...

then his went to cwm ...n flashed cm-11-20150425-UNOFFICIAL-XperiaOverlay-nozomi
and clicked on reboot...
now his cell is not getting on... he was on 19% battery while he flashed...

now-
1) while on connected to charger n pressing vol+, blue light gets on...
and with vol-, green light gets on...
2) remove the charger and press powerkey...he feels only 1 vibration...nothing on screen..
3) while connected to charger, pressing powerkey, nothing happens...
4) while on charger...pressing vol+ and powerkey he feels 3 vibrations...

ps= has usb issues so cant connect to flashtool etc..

any hope?
