I so appreciate these instructions and the toolkit. I just replaced the battery and everything is in working order again. Thank you! As someone already mentioned, the only part I had trouble with was Step 2. The opening tool was not slim enough to insert between the back cover and the metal housing. I had to use a razor blade/box cutter blade and was careful not to hurt myself, but that did the trick. Also, the hall sensor flex cable (see Step 8) entirely came off of the plastic frame during step 13. I must have bumped it when removing the battery. From the pictures, I was able see how it should be reattached, so that turned out ok as well. Thanks again for making this possible! Go IFIXIT.com!
