Here's a solution that worked for me:
My ipod would not charge. It kept going from the "please wait, very low battery" screen to the apple icon screen and then back again. I've been trying different things mentioned on this discussion for a few days, but none of them seemed to work. A few minutes ago, I started screwing around with all of the different methods, combining some of them and seeing what happened. Here's what went down. And this may sound kind of complicated, but I want to make sure I get every detail so that it works for everyone else:
I plugged the ipod into the computer and did the reset thing where I held down the menu and select buttons while the screen was at the "please wait, very low battery" screen. I CONTINUED to hold the buttons down, even when the screen went blank, and CONTINUED to hold them down when the apple icon appeared. As soon as the screen went blank after the apple icon appeared, I let go of the buttons. The apple icon appeared again, and I did the reset again, holding down the buttons until the screen went blank, and then I let go of them. I would continue to reset every time the apple icon appeared, letting go of the buttons just when the screen went blank. Eventually the "please wait, very low battery" screen would return, and I would start the whole process again, remembering to hold down the reset buttons all the way from the point where the "please wait, very low battery" screen appeared until the screen went blank AFTER the following apple icon disappeared. After the 3rd or 4th time going through this, I then did the reset one more time at the "please wait, very low battery" screen, again holding the buttons down through the following apple icon screen. But then, when the 2nd apple icon screen came up, I held down the PLAY and select buttons to go into disc mode. At first it worked. It went into disc mode. Unfortunately, the screen said "ok to disconnect" rather than "Do not disconnect". A few seconds later, it returned to the "please wait, very low battery" screen again. So I did the whole process again, going through the cycle about 3 or 4 more times. This time, I made sure that only 2 or 3 apple icons were coming up between each "please wait, very low battery" screen. I then tried going into disc mode again, after resetting one more time on the "please wait, very low battery" screen and remembering to hold down the buttons all the way through the first apple icon screen. When the 2nd apple icon screen came up, I held down the play and select buttons to go into disc mode, and it did. And this time, it said "do not disconnect" and itunes was reading the ipod and syncing it. At this moment it is done syncing and is charging in disc mode. Please note that the ipod was plugged into the computer during the whole process.
I know this was a very long explanation, but I wanted to make sure everything was covered. I really hope this helps some of you, since it seems like some solutions only help certain people.
