@Brianrh If it runs Android, can I have you install a terminal emulator and check: https://forum.xda-developers.com/t/trying-to-recreate-entire-partition-table-for-nexus-7-2013-flo.3881263/post-78581593 , especially if you're on 17.1, pretty sure 17+ use the FloX packages which require the repartitioning.

If your results don't match up, then you may need to find the "back to stock partitioning" recovery package from the Flo forums over at XDA.

Not sure if Restock returns it to the stock partition layout or not, FloX was very recently introduced iirc.

Edit: Sorry, replied to the wrong user at first.
