I took my apart because there was condensation under the touch screen. While doing this I found that there are several modifications to these steps.
1. Use a Philips PH00 as its a better fit.
2. Don’t cut the band. I was able to use a thin spudger to pry around it and get it off. If you do need to replace the band you can find one on Amazon.
3. Don’t scrape away the adhesive; you need that to re-attach the band. You may need to move some of it but you don't need to scrape it clean.
4. At step 5 I found it better to push in the single button and then pry the outer gray casing off. The buttons didn’t appear to remove after the casing was removed.
5. Before step 6: There are 4 clasps that are holding the top and bottom parts together. Those need to be removed before you can pry it open.
