I have the SM-N910G Note 4 and I rooted it and added twrp custom recovery. Then I bought an app called phone info (Dev is here on XDA) and according to the app my version of KitKat 4.4 is old and upon checking there's a newer version available.

When I went through Settings > About Device > Software Updates > and tried to update: "The operating system on your device has been modified in an unauthorised way. Try downloading software updates using Samsung Kies on your PC or visit customer service center"

So I installed Samsung Kies and got the following error: http://oi57.tinypic.com/2a6o9ic.jpg

The thing is I tried what it said and disconnected my battery and tried again and it downloaded the whole update 1.6GB all over again, and failed with the same error. But this got me thinking and I checked C: temp directory and sure enough there where two files 1.57GB exactly each. So I saved one of them to the desktop with the idea if I changed the files extension to ??? something Odin can work with, could I update that way?

I can't seem to find the XSA Australia firmware (my phone is not a carrier version), and sammobile keeps cutting out on me so I've given up on that site. Just want to update KitKat to the latest version.

Thanks for reading.
