stevenz: You can download the Telecom variant of the firmware from samfirmware.com and flash it with Odin. As long as it is in fact an N9005 then that should sort you out. As it's a genuine firmware it shouldn't even trip the Knox counter if that's a thing you care about (I didn't).
They have the latest MJ7 firmware which was only released late last week.
It's something like a 1.5GB download.
