AT&T Support:
Amanda: I have just read this update With your "update" AT&T has temporarily suspended it because it was not updating properly on the device.
Amanda: Sorry, this is apparently a huge issue so Samsung had to pull it for the time being.
Amanda: I apologize for the inconvenience...
The update showed up on my Note II a couple of days ago. I downloaded it, restarted, failed at 24%. Factory reset Note II. Downloaded it again, restarted it, and failed at 24% again. Factory reset and tried again. Update no longer shows up. :(
