    • Remove the following three screws near the top edge of the logic board:

    • One 2.0 mm Phillips screw

    • Two 2.3 mm Phillips screws

    Can you use the same colour coding as with The above sizes? [HvL]

    These colors are too close together.. One red, two yellow.. Please.

    Thanks for the comment! I adjusted that step, should be much easier to see now.

    If you're ever having trouble seeing screw markers or other small details on a step, you can always view a larger version of the image with the "View Huge" link on the top left corner of the image.

    Can someone explain what the copper/ribbon is that the lower yellow marked screw goes through is for? Perhaps only heat dissipation? The ipod I have was given to me with much of the glass smashed and picked out, so some of this is just missing. Obviously I can't put it back...

    • Use the edge of an iPod opening tool to gently pry, but not remove, the rear-facing camera away from the rear case.

    • Do not attempt to remove the rear-facing camera yet.

    When you insert your tool to remove the rear camera make sure you have the tip all the way in. You can accidentally grab the middle of the camera assembly and it will come apart - and you'll have to replace the entire camera.

    • Use an iPod opening tool to slightly lift the edge of the logic board next to the battery enough to grab it with your other hand.

    • Do not excessively bend the logic board, as it is very thin and fragile.

    • Be very careful not to lift too much as the volume control ribbon cable is still connected and will tear very easily.

    • While gently lifting the logic board with one hand, use an iPod opening tool to lift the logic board near the copper tape at the logic board's top edge.

    • The logic board will be lifted adequately when the last display assembly connector has cleared the top edge of the rear case.

    Use extreme caution when lifting the board. There are 2 ribbon cables that are extremely fragile, 1 connecting the rear facing camera and another connects the volume controller flex on the logic board.

    Adding to Evon's comment:

    BEFORE YOU LIFT UP THAT BOARD...

    Use your plastic pry tool and make sure the flex cable, between the board and power button is not on top of the board. Take your time because even the slightest snag can tear that flex cable which leads to de-soldering/soldering the battery & flex cable.

    Once the board is lifted the first time I usually put a piece of Kapton tape over that area of the cable in case it has to be pulled up again.

    Can you explain this in a little more detail?

    I have done a dozen or more iPod screens without any issue. I have one here now that does nothing. Just a black screen. It won't even take a charge.

    Should I simply desolder those pads and then resolder? Sort of like unplugging and replugging to reset something?

    Thanks!

    Ciao dopo aver seguito il tuo aiuto per come cambiare la batteria io ho rimontato tutto ma la barra di sblocco non scorre più o i comandi in quella altezza del touch , tutto il resto funziona perfettamente.Dove potrei aver sbagliato?

    Potete aiutarmi grazie

    I placed a penny between the battery and board and it held it in place at just the right height.

    I was so so so so careful when lifting the logic board past the flex cable on the power button. Before final assembly, plugged it all in to test and it booted OK. LCD and Digitizer worked. Went to power it off and found the power button wouldn't work. Sure enough, the tiny (<0.5mm) strip of copper in that power flex cable had torn right through. About to pitch this rotten, stinking thing across the back yard into the trees. I've spent 5 hours of my life fixing this today! Aaargh!!!!!

    On this step i broke the entire board, so it now is a Apple Galaxy Fold, also the battery exploded .-.
