Unfortunately, I decided to accept the upgrade for my Nexus 7 (2013) to 4.4 yesterday. After the update, several apps stopped working (e.g., Pac-12 Now), but worse, the new "locations" feature completed broke my GPS. GPS status could not get any lock and Google maps would not work (also, Yelp and Tripadvisor). After a lot of hassle, I was able to restore the tablet back to 4.3 (JSS15J) using the Nexus Root Toolkit. The problem is that that tablet immediately downloaded 4.4 again and keeps bugging me to update (which I am not going to do until they fix KitKat). 1) Any way to get the older OTA's for 4.3 (i.e., JSS15R)? 2) Any way to get it to stop bugging me about 4.4?
