FlatPress

It’s been quite awhile since I posted on my Nexus 7 - I can only say that it works, very well, and is exceptionally good to stuff in a bag and let you to web and email stuff on the move largely without the restriction of a small screen. It is also becoming an invaluable assistant in mobile camera image processing from my DSLR, but more about that in another post.

The Nexus 7 shipped with Android 4.11 and has had two incremental upgrades since then to 4.12 and 4.2. Since rooting my Nexus and changing the UI to tablet layout it has steadfastly refused to upgrade . With TeamWin installed for recovery my next step was to download the update ZIP file from Google to manually update the tablet - it didn’t work but thankfully gave me a couple of error messages. This led me to download an “as shipped” build.prop file which I had edited to go to the tablet UI and replace the edited on on my system. I also had to rename one of the signed certificates at which point it magically updated to 4.1.2 and then the OTA then updated to 4.2.

One important step if you want to keep root - install OTA RootKeeper which will allow you to backup your root access and then restore it.
