My wife's wifi Nexus 7 has been getting the update notification for 4.4.1 for the last 10 days or so. Every time, without exception, when she clicks update, it will download the update, start updating for about 1 minute with the picture of the android's chest cavity open, and then say error and show a picture of the android laying down. This has happened at least 7 or 8 times now. She just got a notification for 4.4.2 about 10 minutes ago and it did the same thing. She's at the point where she doesn't even try to update it anymore; she just ignores the icon. Side loading is not an option. I'd prefer for the OTA to actually work. Any suggestions or advice? Thanks!
