It seems the latest OTA does indeed fix most if not all of the 4.4 bugs so I'm trying to update. I removed fotakill, all the xposed framework apps and any other system tweaks I could think of, but is still falling. My best guess is that adblock effed up when I tried to disable it and is causing the update to fail.
Does anyone have a stock copy of the 4.3 hosts file that I could use to get the updates to go through? I'd rather avoid reflashing to stock if possible.
