Q: I recently bought a fifth-generation iPod nano and I’m trying to put it into diagnostics mode but I can’t seem to do it. I’m reseting it and then I hit the center button and the next button but it doesn’t do anything.
A: Actually, the correct sequence to put the iPod nano into diagnostics mode is to hold down the center button and the previous track button simultaneously after resetting it. More specifically, reboot the iPod nano by holding down the CENTER+MENU button until you see the Apple logo appear, and then switch to holding down the CENTER+PREVIOUS buttons at the same time and the diagnostics screen should appear.
This sequence applies to all click-wheel iPod models from the fourth-generation iPod to the current iPod classic and fifth-generation iPod nano.
