Go back
Why don't you want to go back to MJ5 first? I was in the exact position. I was at NB4 rooted and couldn't upgrade. I ended up flashing MJ5 to the note 3 which left it unstable with a different baseband then build number.I followed this document with these files. Google "Restore for MJ5 Doesn trip Knox" Click the first link. I installed the nb4 update off the extsd card. Then did the adb sideload to get to NC2. No custom status or Knox trip straight official 4.4.2.

Ok, I made a slight mistake...the upgrade didn't fail on a2fsck...rather it was e2fsck.
Restored the SafeStrap NB4 backup.
Unrooted.
Rebooted to recovery and tried to load the update from SD and ...same thing. It complains abut e2fsck.
Hey, that $100 is still on the table if someone wants to try to fix my issue.
Just PM me.
