[Q] "Invalid magic string" - Downgrade Android 4.4 to 4.3

You can flash a Jelly Bean based ROM if you want but that will have no effect on the KNOX flag that you have probably already tripped. Users of supported devices who have not upgraded their bootloader to KitKat can flash @civato
's FlexNote ROM if they want to experience KitKat on the Note 8.0 without tripping the Knox flag.
Thanks for your kind assistance.
Ive flashed the 4.4.2 KitKat with Odin and the device is working.
However, I was not able to flash the JellyBean rom as it prompted the "Invalid magic string" error again.
I'm using this Google Play: MultiWindow Manager app to enable all my programs to run multi-windows.
With KitKat firmware, I was prompted the following error message after rooting:
java.io.FileNotFoundException: /system/csc/others.xml: open failed: EROFS (Read-only file system)
Hence, I would really need JellyBean back.
