    • Lay your eReader down so the back cover is facing up.

    • Insert the flat edge of an opening pick between the frame and the bottom left corner of the back cover.

    • Push the pick downwards at a slight angle until it slides under the back cover.

    • Slide the pick toward the bottom right corner to release the clips along the bottom edge.

  3. xrRL4gFPnCQVD66u

    • Remove the pick and reinsert it under the bottom left corner.

    • Angle the pick flat under the back cover and rotate it around the bottom left corner to release its clips.

    • If you're having trouble, try twisting the pick to lift the corner clips out of their slots.

  4. gZwNcpcZAwbgURWY

    • Slide the pick toward the top left corner to release the clips along the left edge.

    • At this point, you should be able to grip the back cover and release its remaining clips. If not, slide a pick under the perimeter of the back cover until you can grip an edge.

    • Grip the left edge of the back cover and lift it away from the eReader to release the remaining clips.

    • Remove the back cover.

    • During reassembly, align the back cover over the eReader and press along the perimeter until all its clips snap back into place.

    • The entire surface of the eReader's internals is covered in a thin, plastic-like waterproof coating. Keep the following in mind as you continue disassembly:

    • While this won't hurt your device, removing the coating compromises the device to potential water damage.

    • The coating is brittle and can flake into many small pieces. Heating the coating helps, but working with it is still a time-consuming process.

    • The ZIF connector locking tabs are coated in a gel that can jam the hinge and keep the locking tab from completely unlocking. Make sure the tabs are completely upright before disconnecting any cables.

    • Depending on your repair, you might have to remove the coating from ZIF connectors and their cables.

    • Use the tip of a spudger to scrape up the coating along the white battery connector head—enough so you can grab clumps of it with pointed tweezers.

    • Use pointed tweezers to peel off all of the coating around the battery connector head and its socket.

    • If the coating becomes too brittle and hard to peel off, reheat the connector and try again.

    • This is a meticulous process! Failure to remove enough of the coating could damage the plastic head during disconnection, so take your time!

    • Insert the point of a spudger under the edge of the battery connector head opposite of the cable.

    • There's a surface-mounted component close to the connector. Be careful not to touch it with your spudger!

    • Lift up the connector with the spudger to separate the rest of the coating and disconnect the battery.

    • During reassembly:

    • Inspect the connector head and its socket for any remaining coating that could prevent a good connection.

    • Peel off the coating, heating the area when the coating becomes too brittle.

    • It doesn't have to look pretty! You just need to remove enough coating so the connector head sits properly in its socket.

    • There are surface-mounted components next to the power button ZIF connector. Follow the instructions carefully to avoid dislodging them.

    • Insert the tip of a spudger under the right side of the ZIF connector's black locking tab.

    • Lift up the locking tab with the spudger to unlock it.

    • The locking tab should be nearly vertical when unlocked. If not, gently push the tab forward to compress the gel and completely unlock the tab.

  12. WWlXXZKyXhx43ns2

    • Apply a heated iOpener to the power button ZIF connector for 90 seconds to soften the coating.

    • Alternatively, you can use a hair dryer or a heat gun.

    • Because of the awkward angle, the next two steps requires some patience to avoid tearing the cable. Work slowly and apply heat regularly.

    • Use blunt nose tweezers to grip the power button cable close to the head

    • Twist the tweezers toward the top of the eReader to separate enough coating for the cable head to be angled above the battery.

    • Give your tweezers enough room so you don't puncture the battery as you twist them.

    • Gripping the tweezers closer to the tip can help you get a tighter hold on the cable.

    • Grip the power button cable close to the head and pull it away from its ZIF connector slowly and steadily to separate the coating.

    • If the coating feels stubborn, reheat the connector and try again.

    • Keep pulling on the cable until it comes completely out of its socket.

    • During reassembly:

    • Inspect the head of the cable and the ZIF connector for any remaining coating that could prevent a good connection.

    • Peel off the coating—heating the cable and the ZIF connector when the coating becomes too brittle.

    • It doesn't have to look pretty! You just need to remove enough coating to have the cable sit properly in its connector.
