Went back together easier than taking apart!
Replaced earpiece, the only tricky bit is getting the plugs back in the sockets, easier if you slide it open!
I re-assembled in reverse order, don't know what is meant by putting buttons last as you need to put the two screws back which are covered by the buttons!
Like it was said do not force anything, use a credit card or something similar to pop open!
Although I am a mechanichal/electrical engineer, should be possible for anybody though with a bit of care!
