N9005 - No 4G, 99% sure not a fake, and baseband is correct [NZL] topic

Hi all,

Reluctantly asking for help as I cannot figure out how to get 4G on my note 3.

I only ever get 3g, or H+, never 4g/LTE icons. Speedtest never goes above about 6 megabit's download.

What I know:
-I am on a 4g enabled SIM
-I got 4g on my Note 2 before upgrading
-The device was bought locally (N9005, baseband N9005XXUGNG1)
-Pretty sure its not a fake (CPU-Spy shoes 2.3ghz used, about phone shows 1920x1080, flashed to temasek's CM12 without a problem, PlayStore apps say its genuine)
-No 4g either on stock NZ rom, or CM 12
-The option is set to preferred network type: LTE
-The N9005 International LTE uses 850/900/1800/1900 and Vodafone New Zealand use 1800 frequency for 4g (source: http://forum.xda-developers.com/show....php?t=2574886)

What I don't know:
-How to fix it! Can I flash a different baseband/could that be the problem?
-Is it a manufacturing fault?

Cheers
