    • 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.

Conclusion

To reassemble your device, follow these instructions in reverse order.

Remember: after repairs, your eReader is no longer IPX8 waterproof.

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before you install it.

Make sure each of your device's main functions still work, e.g., LED backlight, touch, Wi-Fi, etc.

Take your e-waste to an R2 or e-Stewards certified recycler.
