File "has unexpected contents" error when sideloading Android 5.0 I have a Nexus 7 (2013) (wifi) and am trying to update the software to Android 5.0. When I try to sideload I get this error:

Installing update...
mount: failed to mount /dev/block/platform/msm.sdcc.1/by-name/system at /system: Invalid argument
Verifying current system...
"/system/app/Drive.apk" has unexpected contents.
E: Error in /tmp/update.zip
(Status 7)
Installation aborted.


How I did it:

I placed OTA file in sdk platform-tools folder. Then I opened up a command prompt and typed in "adb sideload 5a0f7a47588c268c239e58cf568823c6637c5af1.signed-razor-LRX21P-from-KTU84P.5a0f7a47.zip and I got that error.

What did I do wrong?
The app's file has been modified in some way, changed or removed. Look up your build number in settings and search for it on Google. Hopefully you'll find a zip with .img files in it. If you've got the correct img files, reflash system.img and you're able to flash the ota.
