I think my screen was defective. It shows the boot up animation extremely yellowed out and dim/dark. Then it shows my lockscreen with the time for less than a second and goes complete black. I can still make my phone vibrate with the buttons, and do a reset to get the boot up animation again. It's just so frustrating because I really needed this to work and did so much of the hard work to get to the final steps, to find out... that the replacement screen is defective!!!!
