So my digitizer stopped working, just a tiny line near the top of the screen is not working. The rest of the screen work perfectly. For example on the dialer screen I cannot select the most recently called number by clicking on it I have to hit the phone button to dial that number. I am able to drag down the notification screen, so that tell me that the very top part of the screen is still working. It's only the thin line near the top. I called HTC, said it is still under warranty. They also said that the warranty does not apply if the phone has any custom firmware/or has been rooted. Does this mean I cannot send to to them? Or can I just flash a stock ROM and they will not be able to tell? IF I can just flash a ROM which one should I do?
Thanks, Bryan
