My World Book Edition 1 TB won't boot

I’ve been using the product for 2 years without any problems until a few days ago.

It was just too slow, so I rebooted it through administration web page.

Now, it’s stuck at 9% progress for few days and wouldn’t make any further.

Anyone had the same issue?

try a hard reset 

press the reset button bellow the usb for 4 seconds

do you have the blue rings or white light?
