Well, I got Lollipop booting, but... the display doesn't work. I got it detected by my computer and got logcat output, so that's a good start. I know that the problem is because I used display-caf-new and media-caf-new from CM11. I don't even have to look at the logcat to know that. I will try to build again with the normal display and media from Lollipop tomorrow. Also, at one point it rebooted and went into a bootloop, and after that the logcat wasn't accessible. The bootloop may have been since I flashed boot.img before wiping data, and it automatically made my phone reboot. The main thing is, it does boot. See y'all once I get display to work! ;)
