Side note: The reason I didnt originally just flash KRT49H from the Nexus Root Toolkit is because it doesnt flash properly. It always gives me a unknown chunk type error. KRT160 is the only build that seems to want to flash correctly to my device.
I have my Nexus 7 wifi edition here on KRT160 (4.4.0) after i flashed it from the Nexus Root Toolkit. I am trying to update over the air to KRT49H (4.4.2) and it refuses to download! When i go to About Tablet < System Update it just tells me "waiting to download" and then after about 1 minute it just says "couldn't download". What problem would be causing this and does anyone have a suggestion on how to fix it?
