While lifting the screen up with one iPod opening tool, insert a second iPod opening tool in between the outer case and the top left edge of the glass panel.
Remove the first iPod opening tool from between the glass and LCD in the top of the device.
Prying up slightly on the iPod opening tool, insert a second iPod opening tool in between the front glass and the outer case, on the right side of the screen.
Slide the second iPod opening tool along the right edge of the panel to remove the adhesive.
With one iPod opening tool still between the glass and outer case, insert a second iPod opening tool in between the front glass and outer case, on the left side.
Slide the second iPod opening tool toward the bottom of the device to remove the adhesive.
Lift the click wheel out of the way with one hand and use a plastic opening tool to pry the click wheel ribbon cable connector off its socket on the logic board.
Use a heat gun to soften the adhesive underneath the camera/microphone cover.
Pry the camera/microphone cover off the case with a metal spudger and remove it.
It is extremely difficult, if not impossible, to avoid damaging the iPod case near the camera. While this will not affect the iPod's functionality, it will hurt its cosmetic appearance.
You can try this alternative method for removing the cover:
Use a hot glue gun to apply a bead of glue across the cover.
Move the nozzle in the glue for 20 seconds to heat the lens adhesive holding the lens in place.
Press a spudger into the hot glue and hold it in place until the glue cools and hardens.
Pull on the spudger with firm steady force, while using a fingernail to pry on the cover edge.
Continue to push the logic board assembly through the outer case of the iPod with a spudger.
Tolerances inside the Nano are extremely tight. Be very patient and go slowly when removing the logic board assembly, and make sure no components or ribbon cables get caught on the case.
To make sure that the hold switch plate does not catch on the housing of the iPod and tear the cable, feed the switch straight down the center of the device, where the opening is the widest.
The battery on the Nano is attached via solder pads with small holes that go through the battery ribbon cable and attach to flat pads on the face of the logic board. In this step, you will heat each solder pad individually while using a metal spudger to pry it up from the logic board.
DO NOT bridge the connection between the solder pads both on the board and on the ribbon cable with your spudger. Shorts have the potential to ruin the logic board.
Beware of overheating the board and the cable. Only hold the tip of the iron against the pad long enough to let the solder melt. Excess heat buildup has the potential to ruin the logic board or melt the ribbon cable.
Start working from the right side of the battery ribbon cable. Heat the rightmost solder pad while gently prying up from under the ribbon cable to free it from the board.
On step 15, I used a thiny needle (for knitting or something like this) placed into the microphone hole and use this gently to lift up the plate. A head gun must heat the glue before. That saves the ipod from scratches
This it bs. I need to buy new device now. Nothing comes off that easy. My screen shattered when I was trying to pull it up. If you are not a pro, don't do it.
You are supposed to push down from the top of the screen, not up. I managed to get mine out but I ripped the hold ribbon in the process. Luckily I have another one for spares. Good luck next time
I'm sure this can be done, but the tools included in the Ifixit kit are not up to the task. Spent about 45 minutes with the flimsy blue tools and distorted the LCD trying to remove the glass. Then took a heat gun and used the black nylon tool (which I suppose is the replacement for the metal spudger) in the kit. Had the glass out in a single minute. There is no tool in the kit long enough to dislodge the click wheel. I got out my dental tools and finished the disassembly. It is cheaper at this point to just buy another than replace the broken parts. It is a poor carpenter that blames his tools, but you can't cut down a tree with a fish. Use your own tools
