One strip snapped on me, so I ended up using the hairdryer, which is oke, but stay patient!! It took a while before the heat really went into the adhesive ( because you can't get the phone to hot - and you can't bent the battery to force its release - so here is where the patience kicks in). Then assembling back you need tremble free hands to get the connectors back in but those are about the only two challenges I faced. I got it back on and everything works perfect! Geert
