The seven screws should be removed with a 1.5 mm Phillips screwdriver (PH000).
Before disassembly, make sure you write down where the screws are located. Screwing the screw in the wrong spot during assembly runs the risk of breaking the device or its components. The removed screws and individual components (such as brackets or gaskets) must be arranged in the proper sequence to prevent damage, or the screws and the phone's mounting holes must be color-coded.

The two loudspeakers and antennae assembly must be removed.

Disconnect the daughterboard's mainboard cables from the coaxial cable connector.

The connectors are fairly flimsy and readily break, or the cable falls out of the end (lug), if you tug on the cable or pry it with a sharp object.

Tools you may need

1. Heat gun or hairdryer
2. Plastic pry tools
3. Phillips screwdriver
4. Tweezers
5. Suction cup (optional)
6. Guitar pick or thin plastic card

Steps

1. Power off the tablet: Make sure the tablet is powered off before you start disassembly.
2. Remove the back cover: Use a heat gun or hairdryer to heat the edges of the tablet. This softens the adhesive holding the back cover. Once heated, use a plastic pry tool or a guitar pick to carefully pry open the back cover. Start from one corner and work your way around the edges.
3. Disconnect the battery: After removing the back cover, locate the battery connector on the motherboard. Use a plastic pry tool or tweezers to gently disconnect the battery connector from the motherboard.
4. Remove screws (if any): Some tablets may have screws holding components in place. Use a Phillips screwdriver to remove any screws you find.
5. Separate the front assembly from the rear case: Carefully detach the front assembly (LCD screen and digitizer) from the rear case. You may need to use a plastic pry tool or guitar pick to gently separate the two components. Be cautious around the edges to avoid damaging the screen or other components.
6. Disconnect cables and components: Once the front assembly is separated, locate and disconnect any cables or connectors attached to the motherboard, such as the display cable, camera module, etc. Use tweezers or a plastic pry tool to gently lift the connectors.
7. Remove the motherboard: Unscrew the screws holding the motherboard in place, if any, and carefully lift the motherboard out of the rear case. Be gentle and make sure all connectors are disconnected before lifting the motherboard.
8. Access other components: Depending on what you need to access or repair, you may need to further disassemble the tablet to access specific components such as the camera, speakers, or charging port. Follow similar steps to disconnect cables and screws holding these components in place.
9. Reassembly: Once you've completed your repairs or maintenance, reassemble the tablet by following these steps in reverse order. Make sure all cables are properly connected, and components are securely in place before snapping the back cover back on.

Remember to proceed with caution and patience, and if you're not comfortable with disassembling electronic devices, it's best to seek professional help to avoid causing any damage.
