Dead spot on top of the screen
I have a Kindle 1st Gen. its have a dead spot on top portion of the screen for so long now , sometimes it work normal but most of the time not responsive .
I seldom use it, but yesterday I decided to root my Kindle fire. some problem encounter during rooting..stuck fastboot mode..due to driver issue.
but after the successful root... my dead spot problem disappear ..but today the problem resurface again.
I ask some question.
1. It is a software related problem or hardware related problem. ??
i'm on stock ROM right now and i am planning to flash with new ROM later on...I haven't decided what ROM to flash CM 10.1.3 or CM11 nightlies by otter
