It is not difficult to open Ubook. Short instructions: 1.First, we Unscrew 5 screws from the back of the tablet (they are only in the lower part of the case). 2. Heave in the area of contact of the keyboard housing plastic card, I did it with a fingernail. Here, pay special attention to the fact that you do not tear off the keyboard contact, you need to pull the case on yourself. 3. Start gradually separating the back cover housing to the left and right. You will hear the characteristic clicks of the latch locks. So around the perimeter. All. A little caution and courage.
