Before you begin Read the legal information section of this website. Place your Apple iPod nano 4th generation on a clean flat and soft surface, such as a rubber mat or a piece of soft cloth and get the required opening tools
		Step 0 Opening the iPod nano 4G is a complete mystery at first sight, because Apple built in a clever locking mechanism. Once you're past those intricacies the remaining steps are relatively straighforward. Begin by prying off the top cover with a safe open tool.
		Step 1 This is what it looks like when the top cover is removed. The hold switch slider will also come off as soon as you remove the cover.
		Step 2 Remove the two phillips screws near the sides, the screwdriver needs to be at a 45 degree angle to access the screws.
		Step 3 Use a flathead screwdriver to carefully pull out the ipod nano 4g screen module about 1/2 an inch.
		Step 4 This is about as far as the nano screen module will come out.
		Step 5 Slide the blade of the flathead under the hold switch. Be careful not to put too much strain on the ribbon cable as you release the switch from the glue.
		Step 6 Turn the iPod nano 4th generation on it's back.
		Step 7 The tricky part! Push on the bottom of the nano 4g lens and move it left and right. You are trying to push the bottom of the lens under the casing. This will work now, because you partially pulled the screen module out and there is room for the bottom of the lens to move down.
		Step 8 As you can see the bottom part of the nano glass lens is now between the casing and the logic board and the top of the lens now is released from the casing.
		Step 9 You can take the lens out and set it aside.
		Step 10 Open the latch of the screen ribbon cable.
		Step 11 Carefully slide the flathead under the screen ribbon cable and pull it out of the connector.
		Step 12 You can now completely pull out the nano screen module and replace it with a new one if that is your goal. If you want to replace the ipod nano 4g battery, iPod nano 4g clickwheel or iPod nano 4g logic board continue below.
		Step 13 - iPod nano 4G logic board replacement. Pry off the bottom cover with a safe open tool or flathead.
		Step 14 Remove the screws on the sides.
		Step 16 Insert a screwdriver in the headphone jack aperture and try to pull the entire module consisting of headphone jack and logic board.
		Step 17 This is what it looks like when the module was removed from the casing just enough to have access to the clickwheel connector. Open the latch of the clickwheel connector as shown in the image.
		Step 18 Slide the flatheat under the ribbon cable, carefully removing it from the glue.
		Step 19 Detach the connection between the two ribbon cables when they are fully released from the glue.
		Step 20 Now gently pull the nano 4g motherboard module more. It may be necessary to lift the battery from the top to make the module slide.
		Step 21 This is what is looks like when module is being removed from the casing. Success, you have fully disassembled your iPod nano 4G. Once the nano motherboard is removed you can push down on the wheel to make it snap loose from the casing. If you want to replace the nano battery, look at how it is soldered to the motherboard, the replacement should be somewhat self explanatory.
