P.S. To those out there who don't have a super, ridiculously tiny (#000 screwdriver or 1.587 mm Phillips head) and don't want to have to purchase one just to complete this already daunting task, I found that using a screwdriver from a glasses repair kit worked PERFECTLY! :)
Thank you so much, Fina! You have done a fantastic job explaining each step incredibly well! I very much appreciate all of your efforts into skillfully describing the process of disassembling the 2DS. I was able to understand your instructions and thus was able to make a lucky kiddo super happy! Thanks again!
