Before starting, make sure the tablet is off.

Step 2 Back case

Disassemble the back cover. To do this, we introduce the wide part of the opening tool into the joint while simultaneously holding the screen with the suction cup.

With small lever movements, trace the contour with the opening tool. You will hear "clicks" as the plastic hooks are released.

Step 3

Once disassembled, it will remain attached by the speaker cable.

Step 4 Speaker

Disconnect the speaker cable on the motherboard.

Step 5 Baseboard connectors

Unplug and set aside the cables for the volume and ignition buttons.

Step 6 Battery

Remove the adhesive covering the battery connector.

Step 7

Disconnect the battery from the motherboard.

Step 8 Camera

Remove the adhesive that holds the camera.

Operate the connector on the base plate, pushing the black tab lightly at both ends.

Step 9

Disconnect the camera from the motherboard.

Step 10 Touch screen data flex

Disconnect the data flex from the touch screen on the motherboard.

Note that the operation of the connector is identical to that of the camera.

Step 11 Audio connector flex

Disconnect the flex from the audio connector. Again, the same type of connector.

Step 12 Microphone

Separate the microphone from the housing.

Step 13 Motherboard

Remove the 2 Phillips screws that hold the motherboard.

Step 14

Turn the motherboard over, as shown in the pictures. This will remain linked by the flex display data.

Step 15

Disconnect the data flex from the display and separate the motherboard.

Step 16 Touch screen

The touch screen is attached to the plastic frame with a strip of adhesive. We will apply heat to the glass to soften the glue and to peel off easily.

You can use a hot air nozzle or our Hot Glass (recommended), a high temperature thermal retention blanket for microwaves. Simply, warm according to the instructions and apply directly to the glass of the screen.

Step 17

Penetrate with the pick in the joint between the glass and the plastic frame.

Scroll around the contour while placing thicker quills in your step as a wedge.

Do not cut the flex of the touch screen when passing with the pick.

Step 18

Peel off the touch screen from the opposite side of the data flex.

Step 19 Display

Peel off the adhesive that holds the display with the plastic frame.

Gently push the display from the back.

Step 20

Gradually separate the display frame, helping with the plastic opening tool from behind.
