HTC directly updated over-the-air (OTA) from 1.5 android to 2.1 android firmware on my handset. Since that time, the touch-screen (which is miscalibrated) can no longer be recalibrated, because the menu item has disappeared.
I have, of course, requested support from HTC via email, but I doubt that they will find an answer here, and I suspect my phone is now junk, unless some enterprising Phone-savvy person can figure out how to restore this thing. There is sadly no backup that I know of that I can use to restore this phone, and going back to Android 1.5 has a host of issues associated with it.
How can I get this working again? I could use any technique that will let me recalibrate the touch screen, even if it isn't the built-in menu item, maybe there is a way to bring that up indirectly somehow, or through an add-on app?
Incidentally, HTC HERO's seem to be famous on internet cell-phone forums for glitchy capacitive touch screens.
