So my nexus 7- 2012 tablet has been set up to use Cyanogenmod 11 nightlies. Lately it has been sputtering and acting seriously weird with odd crashes and update strangeness.  So I put on my propeller hat and start digging into the system.  And yep, oops…I’ve been using GAPPS for an older version of the operating system for months.. Bang head on desk. Install new GAPPS package….and suddenly my ol’ tablet is rockin’ like a new one.

Cyanogenmod = awesome custom ROM for android devices. -replaces stock android operating system.
Nightlies= latest raw updates. (beta code).
GAPPS= Google-Apps = framework and base Google application packages.
