I have a rooted stock Nexus 7 2012, I'm trying to update it to 4.4.3 from 4.4.2 but it keeps failing.
The update downloads, I hit install, it reboots into CWM Recovery, I select the option to install an 'untrusted zip', the update begins and then fails due to the following error:
"/system/app/bluetooth.odex" has unexpected contents.
I've tried flashing the OTA using CWM and forcing the OTA update using Nexus Update Checker and both have failed with the same error.
I'm no longer being prompted for the update either but I'm still on 4.4.2.
