    • 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.

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

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

      • Six 5.2 mm Phillips screws.

      • One 2.7 mm Phillips screw.

    • 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 with the flat edge of a screwdriver.

    • once the cable, highlighted in the orange box, is completely removed then you may take off the entire outer casing.

    • Pull the Wi-Fi board away from the motherboard by its edge closest to the headphone jack.

    • Pry the Wi-Fi antenna connector straight up from its socket on the Wi-Fi board.

    After reassembling it, I switched my Nintendo DSi xl On and only the blue power light, is on after that it doesn't respond any more, except while charging it blinks

    • Flip up the black latch and disconnect the D-Pad/Power Button ribbon cable.

    • The power connector (with red and black wires) is difficult to remove without damaging it, unless you take a moment and understand how it works. Look at all of the photos for this step before continuing.

    • The connector is two pieces -- a white "male" piece (connected to the wires), and a beige "female" part (soldered to the main board).

    • There is a small "notch" in the female part, to give you a place to insert a small flat-head screwdriver. Put the corner of your screwdriver in there, and twist it gently to push the white part up (away from the main board). Do not try to pull it to the right (towards the battery board).

    • If it does not lift easily, try again with a smaller screwdriver. You might be pulling the female connector off the board, which will be difficult to repair.

    • If you have not already done so, disconnect the two bottom-LCD ribbon cables from the main board by prying up the black latches and pulling the cable out to the side.

    • The ribbon cable (marked in blue) for the touch screen is particularly thin and fragile; be careful to avoid bending it more than necessary.

    • Flip up the latch and remove the touch screen cable.

    • Flip up the latch and remove the top-screen ribbon cable.

    • Pry up on the orange cable to disconnect it from the main board, much like the antenna cable on the Wi-Fi module.

    • Do not pull on the orange cable that connects to the bottom of the motherboard.

    • Remove 4 Phillips screws from the board.

    • Lift the main board from the bottom end and flip it over to reveal the last connector.

    • Keep the main board fairly close to the case, making sure not to damage the last ribbon cable holding it in place.

    Add Comment

    • Disconnect the ribbon cable by gently using a plastic opening tool to flip up the black connector latch. The cable should easily slide out from the connector.

    • The motherboard should now be free from the rest of the device.

the screwdriver needed is not a phillips #00, but a phillips #0000. I went down to Sears with my DSi and the Craftsman #00 was too large, the Craftsman #0000 (item 41645) fit perfectly, and was only two bucks
