Finally I tried restart a old windows version, load factory image from the techtablets, and load a clean windows 10 version with drivers manually, and I dont fix that.
Then I watched the youtube mod and it was easy to open, I tried it and I see that the connector of usb 3.0 and touch pad were disconnected. I connected that and work perfectly.
Thank you, because is the only forum with good information for ezbook 2.
