    • Remove the 5 visible Phillips #0 screws.

    • Remove the 4 hidden screws under the rubber feet (one under each rubber foot). If you only partially pry up each foot enough to get to the screws, you can reuse the feet without having to re-glue them.

  3. Disassemble this back piece, since it will ease a lot the prying of the bottom part By doing this, you will avoid ending with couple of "clicks" broken, specially during the tear up If you have the 3G model, be sure to remove the SIM card from this slot before going any further.

  12. By removing this flexible metal ring sticker, you disable the Write Protect of the bootloader's flash.

    • This risks making the device unbootable, therefore bricking the device beyond repair. Of course, there are basically no other modifications that can be made to the interior of a Samsung Chromeboook 3 anyways.
