Got stuck trying to update to kitkat (me too)
I believe my case is very similar to that starting this thread so I thought I'd just continue (hopefully not violating rules).
My Android was ICS stock version and my wish was to upgrade to KitKat.
(I did not make any backup.)
I followed these steps:
I rooted my system and installed PhilZ Touch 3 CWM Base version 18.104.22.168.
Then I proceeded to the upgrade following this guide:
"Update Galaxy Note N7000 to Android 4.4.2 KitKat Lightning ROM"
[sorry, am not allowed yet to insert ext links]
Step 10 resulted for me in:
set_metadata_recursive: some changes failed
E:Error in /sdcard/N7000-STABLEv1.zip
I retried step 10 using SlimKat - N7000 but with the same (Status 7) result.
This CWM seems ready further actions although it keeps looping even upon switch-offs (needed to remove battery to switch off effectively).
I hope all details have been given.
Please do advise me about further steps.
