So this evening began like no other, until a few strange issues started plaguing my Nexus 7. Firstly the owner picture won't update. of course I've restarted my rooted device (no custom ROMs or anything) but to no effect. secondly I can no longer add Widgets to my homescreen. a few were successful but now whenever I try to add one it takes me to the associated app or link, and then back to the widget/app drawer.
