so i was able to finally able to get the ota on my nexus 7 and after downloading and rebooting to install everything seems fine up until i get a prompt asking if i want to "install this untrusted zip", after selecting yes it proceeds for a second and then says update failed and reboots to 4.2.2. ive tried installing it via ota a few times and everytime the same problem happens. im stock rooted no fancy kernals or anything just completely stock and rooted i have clockworkmod recovery installed and thats where im getting the prompt. any help would be appreciated thanks.
