As with probably everyone we have all seen the IFIXIT tear-down of our device and they had some issues taking it apart, and even damaging the plastic bezel on the housing. So i was intimidated, but i wanted to see if it really was that hard.....
Guys its NOT HARD AT ALL....The hardest part is the plastic on the sides is actually pretty soft, but the only damage i had was before i heated the device up i tried trying to pry the speaker cover off with just a screwdriver (bad idea). This gave me some very very slight damage where i was prying against the plastic. With the heat and then pry this wont happen. (the adhesive is ridiculous by the way, some very strong stuff (I blame 3M)
Step 1: Heat up device with a hairdryer at the bottom speaker cover, your going to need to get it pretty hot (be careful, your speaker is under that)
Step 2: With device still nice and toasty take a spreader ( i used a guitar pick, but i was thinking a hot razor blade slid under might be more effective)
Step 3: Gently work spreader under speaker cover and work from one end to the other, I used a razor blade to get a gab and then work it off, wasn't to hard since the adhesive is warm and easy to peel off the cover. (be careful, you still have to use that adhesive to put it back on, or use another adhesive)
Step 4: Once bottom speaker cover is off take your spreader and place it between the black part of the housing and the silver part (essentially the phone is placed in a aluminum shell, and you need to get it out).
Step 5: With Spreader placed between the chases gently slide from one end to the other, on the right side by the speaker cover is a white tab, slowly leverage this tab separating the black housing from the silver housing, then pry up from one side to the other tell you get a decent gap.
Step 6: Take your separator and go a side of your phone, doesn't matter which one is done first, just like the previous step, place your spreader between the black housing from the silver, and gently slide from the bottom up, if your doing it right you will hear 3 clicks and that side is separated.
Step 7: Take your spreader and repeat Step 6 on the other side until you hear three clicks.
Step 8: Take spreader back to the bottom and gently pry up pulling the black housing out of the silver Back housing, while doing this you may need another spreader to pry the bottom and then go around the sides to make sure it comes out freely.
