READ THE DESCRIPTION!!
(sorry for the english on the video, I'm brazilian and a not so great english speaker)

I've made this video because the site 'iFixIt' said it that the phone is a "1 out of 10" in repairability score. I disagree. This video shows up the 2nd attempt to disassemble the phone.

Keep in mind that I'm NOT using any metal tools as to not bend the sides too much and dent it.

About the top bezel, it's because before trying to open the phone (that had water damage) I tried pulling the bezel up with a needle to send hot air through it to see if the issue was with the power button. I glued it with superglue to keep it in place (DO NOT TRY this method, it will bend the bezel and there's no way to remove it without opening the whole phone - I guess - unless it's the bottom bezel).
