I'm dabbling with custom ROMs for the first time, so I think I'm missing something. But I flashed Slimbean on my Nexus 4, and could not activate the wifi or bluetooth radios. I followed exactly, and as well. I also found , which isn't mentioned on any other installation guide, but it didn't do anything. I've been over this several times, I've probably wiped my cache, userdata, dalvik, and system six times, and flashed the Slimbean zip even more times than that, with no change. What am I missing here?
