Step 1: Screen Preparation
To begin, soften the adhesive holding the screen in place using a heat gun.
Action: Apply heat to the screen edges with a heat gun set to its lowest setting. Use sweeping motions, maintaining a distance of approximately 8-10 inches from the device.
[Important Note]: Avoid holding the heat gun stationary over one area to prevent overheating or damage. Consistent, sweeping motions are key.
Step 2: Prying the Screen
After heating for 1-2 minutes, you can start to gently separate the screen.
Action: Use a plastic opening tool to carefully pry the screen loose. Start at the top right corner and work your way around the device.
⚠️ [Warning]: Be cautious not to bend the screen by inserting the tool too deeply into the device.
Step 3: Separating the Screen and Cable
Continue to detach the screen from the tablet's main body.
Action: Slide a plastic opening tool and a spudger along the underside of the screen. Apply sufficient force to peel the screen and its adhesive strip away from the device.
[Caution]: Pay close attention to the orange cable that connects the screen to the mid-bottom section of the device.
Step 4: Disconnecting the Screen Cable
The screen is connected via a delicate ribbon cable.
Action: Using tweezers, gently pull the orange cable from its connection point on the screen.
Step 5: Disconnecting the Battery Connector
Next, disconnect the battery itself.
Action: Locate the wired connector on the top-right of the battery. Lift this connector gently to disconnect it from its socket.
⚠️ [Warning]: Handle the battery with care to avoid bending or puncturing it.
Step 6: Removing the Battery
The battery is secured by adhesive strips.
Observation: Four black tabs are located on the bottom of the battery, attached to adhesive strips underneath.
Action: Pull each tab individually until all four adhesive strips are removed. Once the last strip is removed, the battery should release.
To reassemble your device, follow these instructions in reverse order.
