Nexus 7 (2012) Omni 6.0.1 Install failure I was trying to follow the instructions at http://www.teamandroid.com/2016/01/20/install-android-601-omnirom-nexus-7-2012-marshmallow-custom-rom/2/, which walk through downloading omni-6.0.1-20160115-grouper-HOMEMADE.zip, copying it to the root of the sdcard storage, and using clockwork recovery module to wipe the device and install it. I ran into a problem when trying to install the ZIP file downloaded from https://www.androidfilehost.com/?fid=24369303960685419 (which I was able to successfully select). An error is reported:


  ApplyParsedPerms: removexattr of system/bin/backuptool.sh to 0 failed:
  Operation not supported on transport enpoint


Subsequently a Status 7 failure causes the installation to abort. The failure happened quite early (fortunately?) so I am still able to reboot and use the freshly wiped device, but I'd like to install this ROM because 2012 model Nexus 7s are notoriously unusable on Android 5.1.1, which is the latest OS formally available to them.

How do I get past this? The page I was following was supposedly specifically for the 2012 model of Nexus 7, which I have, so I thought this should have worked.

Update: Looking at the updater-script, I suspect this is the line that's failing, but I don't know enough about the design of this package or alternate ROMs to understand whether the problem is in the script or somewhere else:

set_metadata("/system/bin/backuptool.sh", "uid", 0, "gid", 0, "mode", 0755, "capabilities", 0x0);
Using TWRP 3.0.2 (with WugFresh Nexus Root Toolkit 2.1.9) instead of Clockwork worked.
