Hi Guys , sorry cant post pics at work of how to take it apart but hopefully the below helps. Its super simple .
1) Remove the battery & the first screw(the one that's visible) , the second screw is under the round Kangertech sticker so you'll have to tear it off first.
2) Hook a finger behind the negative pin at the top(spring pin) & gently pull at it while at the same time pressing down on the fire button to help push it out. Don't bother pressing against the screen glass as it is stuck on from the outside(To take out the glass it needs to be popped out from the inside) If you now look from the top you should see that your 510 pin has moved a bit out of place. Don't try to force it out any more .Start with the bottom
3) Now at the bottom use a screw driver & push at the front USB port GENTLY. Id suggest an earbud maybe to avoid damaging the USB port. While pushing the USB .At the back press a finger onto the positive pin pull from the inside .Use more pulling force here so it relieves some of the stress you are placing on the USB.
4) By now you should notice both ends top & bottom & sticking out a bit past the metal casing. From here on its just a matter of pull a bit at the top , stop , pull a bit at the bottom , stop , then back to the top. Eventually I just held the device between my thumb & forefinger & whacked it against my other hand & the inside popped out. Hard to explain but it's the same way you smack a pack of cigarettes against your palm.
VERY IMPORTANT :
1)On the outer part of the negative post there is a spring & cap that is held in place & will pop out once you have removed the inner case. Suggest keeping your finger on top as you are pulling out or at least do this somewhere that if it does pop out you can find it & it wont roll away under a cupboard or something.
2) If you decide to pop out the glass cover for the LCD remember to pop it out from the inside. Its held in place by a sticky tape. If you're careful you can reuse the tape but I ended up folding mine so I just dabbed some superglue to 2 corners & stuck the glass back
That's about it I guess.
Guys , my apologies if I've made absolutely no sense. Tried to explain it as best as I could so don't hesitate to ask if you need any clarity.
Wow I didn't realise how much I wrote
