Hi,
have you power off the device?. You must push the power button for ten seconds or so.
Once powered off, you can start whit one or two seconds pushing the power button.
If this not work, you can put a firmware file in a sd card, and whith de device powered off, push both power and back button for some seconds until the recovery menu appears. Then you must try to install firmware for sdcard.
If that not work, you must download the mgftool and try to reinstall the firmware from this utility.
good luck
