One tip when reassembling. These screws are very tiny and difficult to handle even with magnetized drivers, so I used the PH000 tip of the iFixIt kit to pick the screws and screw the first turns. Then switch to a PH00 to tighten them. Actually, using a PH00 of a cheaper set I bought to open the iPod, worked better since the length of the screwdriver was shorter than the case.

I saw some YouTube videos where they were able to reuse the black tape on the new backplate, so I took some time to carefully remove it, without success. However, since I was replacing my iPod 7th Gen with a 240GB disk (thicker than the original), the new thicker back plate did not need the tape since the cables are separated form the case.

There are several hard tasks in this process and this step was hard for me. Took me a while to detach the battery without damaging the cables. But with some patience I succeeded.

Great guide, by the way.
