Good instructions, but as others have said, on the 160gb Gen 6 iPods the blue tools are worthless (sorry ifixit) and it can be a bit difficult to replace the battery beacuase of the Gen 6’s different construction. However, if you have any mechanical inclination and PATIENCE, you’ll be fine completing this repair. Tools I used were to separate panels were a razor blade (like you would use in a Stanley Utility Knife and two tooth scaler tools. They’re used for scraping tarter from dog/cat teeth but they worked fantastic for separating the case. Here’s a link to what they look like/are;
I used the razor blade to CAREFULLY begin separating the case similar to steps 2 and 3. Once case was opened a bit, I gently inserted one of the scalers. Once one was in place, I inserted the other and just worked my way around the seam gently prying the case apart. Came apart fine and the case was not damaged at all. Went right back together and works like new!
