I was able to enable the usb debugging,and then to start the bootloader. However If I connected the phone and tried to execute the adb reboot-bootloader command it didn't worked. So I restarted the phone and entered into the bootloader,then I've done the following:
fastboot erase cache
After the first command,the phone rebooted into bootloader,then the second command finally cleared the chace. Now my uptime is more then 8 minutes,so the phone is working great now
However I will do the complete process on the weekend,but not now as I'am really tired,but I will flash a stock rom at the weekend.
