Can technic partners of lg do it?
I think it's not 5minutes, look there http://forum.xda-developers.com/show....php?t=2470662 for teardown. What I know is that one must freeze underlying glue,which grips the battery, with pressured air. Otherwise battery won't take off "the box".
What is more interesting is can I put a thermal compound a top of processor? What I learned from benchmark results is that my item gets hot way too quicker than other forum members'. Seems like heat dissipation it is not even across the line and I want to help my item keep cool
