Thank you to the previous commenter who said to skip step 8 thru 20. Step 8 can easily break parts to it is way better to avoid it, and it is not necessary to do when replacing the circle pad.
Almost all the screws are interchangeable, but make sure your screwdriver fits and press hard to avoid stripping them in step 1 and step 4
thank you monk333y, the author of this guide needs to correct a couple of things and how hard would it be for her to add steps 21 onward from the other guide?
