I dropped my phone from pretty high up onto pavement Friday and it totally obliterated the glass and digitizer. The phone still boots, and the screen still turns on, complete with computer syncing and audio but it's just a mess of lines. I looked up replacements and services but they're all half of what I paid for it (bought from Craigslist), and I don't think it's worth it. I want to sell it for parts but I want to factory reset it first- seeing as how the touch screen is useless I need another way of resetting it. Any help would be greatly appreciated.
