    • Unscrew the two Phillips screws securing the battery cover to the lower case.

    • The screws remain captive to the battery cover.

    • Grasp the battery cover and lift it out of the lower case.

    • If it's difficult to grasp, lightly tap the opposite side of the device.

    • Using a spudger tool (or your fingernail), lift up the battery from the top.

    • The liquid damage indicator sits underneath the battery. Pry gently, or you may damage the indicator.

    • There's a small tab on the top of the battery to make removal easier.

    • Grasp the battery and remove it from the DSi.

    This is also where the water damage indicator is located, if that's important

    • Two screws are hidden underneath two rubber feet highlighted in red.

    • Use the tip of a spudger to pry the rubber feet out of the lower case.

    • Depending on the age of your device, the rubber feet may crumble apart as you pry them out. If so, use a fine-tipped tool to scrape out any stuck pieces of rubber.

    One of the feet did break on me, tweezers came in handy for picking it out

    Willie Narvaez -

    I unfolded and sharpened a paperclip. You can use that to stab and hook the rubber without tearing it, as the rubber is thick enough to reseal when reinserted.

    Nasty, broke my spudger and the feet in this step.

    • Remove the following screws securing the lower case to the body of the DSi:

    • Six 5.2 mm Phillips #00 screws.

    • One 2.7 mm Phillips #00 screw.

    Impossible d'enlever les vises… trop serré! comment faire?

    • Insert the spudger in between the lower casing and lower panel near the top right corner of the DSi.

    • Carefully run the spudger along the edge of the outer casing, creating an opening between the body and the casing.

    • Continue running the spudger around the body of the DSi until the majority of the lower case has been separated.

    • Carefully lift the lower casing from its bottom edge.

    • The lower case is still attached to the motherboard by the volume and SD board cable highlighted in red. Do not try to completely remove the lower case of the DSi yet.

    • Pry the volume and SD board cable up from its socket on the motherboard using a spudger.

    • Once the cable is completely removed, then you may take off the entire outer casing.

    • Lift the steel battery tray out of the lower case and remove the trigger button/SD board assembly.

    • When removing the trigger button/SD board assembly, don't lose the two steel nuts (highlighted in red) inserted into the lower case.

    • If your trigger button happens to fall apart during diassembly, the third picture shows its correct installed orientation. Be sure the spring is installed in the position shown, and that the two trigger button covers are unique to the side they are supposed to be installed in.

Conclusion

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

I noticed some pencil marks on the inside of the lower shell that must have come from the factory. There is an m/ to the right of the foam pad, an ax to the right of that, and some kind of numeric marking that says 1T7 12 above the ribbon cable. I'm wondering if it has any significance.

Matthew Maulding -

Hi! I accidentally stripped the screws above the game slot , any ideas how to unscrew it without breaking my dsi?
