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...
