My Nexus 7 LTE is rooted with stock ROM. I am trying to upgrade to 4.4.2 and it failed because of the error message:
/system/app/books.apk unexpected contents. Installation aborted.
However, searching the folder using ES Explorer, I don't even see this books.apk
My questions are:
1. How is it possible the upgrade fail for an apk that didn't even exist?
2. If all else fail, what can I do to upgrade to 4.4.2 via OTA?
