Make the home button to get back on track? With what?? force-power down and reinstall.. and full drain.. and whatnot? Not really. Of course, it can shake itself together and get back working (as a hardware) forced by the software.. temporarily. In reallity, though, it is a HARDWARE ISSUE. Rather cheap and easy to fix. It is the bottom loudspeaker/vibrator circuit board, prone to fail. £11 to buy and 10 minutes to tinker. Works as brand new!! Please feel free to spread the news. Loads of OP2 out there suffering...
