Unhappy My Glass Freezing

Hi dear,
I hope that you will help me in my problem with google glass.
After putting it to be charged one night , in the next day I tried to start it but it didn't work , it is Freezing on "Glass" screen and I tried the Hard reset but no response the glass turns off but always Freezing on "Glass"screen.
The last update was EX17.3 before it freezing in "Glass" veiw .
How you can help me to return it to factory reset again or to Beyond this problem.
Thanks alot
