In a fit of retard rage, I threw my Kindle and shattered the screen. The digitizer was fine, but the lcd cracked. I was going to change the lcd only, but man, what a pain in the arse.
It was easy. The directions on here were easy to follow. Only thing that was difficult was that the reassembly never mentioned that you need to put the charging port in first. I have to disassemble again, but no problems.
