    • Using your spudger or metal tweezers, work the rubber screw covers out of their sockets, found on each of the four corners of the back cover.

    • Have patience! These are held in with glue and can take time and a few attempts to remove.

    • Using a PH00 screwdriver, remove the 5.8mm screws found beneath each rubber cover (4 total).

    • Using the flat end of your prying tool, work the back cover away from the rest of the gTabet.

    • Starting near the charging port, work in one direction around the perimeter of the device.

    • Do not insert prying tool deeper than is necessary to separate back cover. You may damage other components!

    • Lift off back cover to reveal the interior of the device.

    • The battery is the large black square that dominates much of the device interior.

    • There is tape holding several wires in place. This must be removed before the battery can be removed. Peel it gently; you will want to use it later.

    • Using a PLASTIC tool of your choice, push both ends of the power cable connector, one at a time, away from its housing. This will slowly wiggle the connector out of place.

    • The white connector(red markup) comes off while the off white connector(orange markup) stays on the motherboard.

    • Using tweezers, remove the protective foam backing arch from the front-facing camera.

    • Pull the camera out of its housing and move it aside.

    • Be sure to move any wires out of the way before attempting to move the battery, as these are still connected and shouldn't be stressed!

    • Gently lift the battery up and away from the rest of the device and set it aside.

    • Using tweezers or the spudger-wiggle technique, disconnect the two wires (shown here to the right of the battery power cable housing) from their housings.

    • It is very easy to damage the wires going to and from these connectors! Going slow and using as little force as possible will help to prevent this.

    • Find the antenna receiver affixed to the LCD Screen chassis with foil tape. Gently peel back the foil tape and remove the antenna.

    • Now follow the wire attached to the antenna back to where it connects to the motherboard. Gently rotate and lift the connection until it lifts away.

    • You may now install a replacement antenna by reversing these steps.

    • Disconnect the LCD Video cable, shown to the right of the battery power housing. Gentle application of pliers is acceptable for this extra large connector.

    • Two additional connections must be undone before moving on. One can be found to the right of the front facing camera housing on the motherboard. It is small; treat it gently.

    • An identical connection can be found next to the antenna connection of the motherboard, diagonally across from the one you just disconnected.

    • Now all necessary wire connections have been undone and the motherboard can safely be removed.

    • The motherboard is mounted to the chassis by 8 screws, which must be removed.

    • Two of the screws are different from the others. The majority of them are 3.3mm. The outliers are 5.9mm(orange) & 5.7mm (yellow). It is recommended that you make a "Motherboard Pile"; a designated area for the screws needed to hold the motherboard in place.

    • Gently lift the motherboard away from the remainder of the device. Set aside in an anti-static bag if you have one. If not, avoid placing it on surfaces prone to static shocks (fabric or metal for instance).
