Can I re-enable "Global" / LTE Band 3 network mode on Lollipop?

Hi,

I am in Australia and I got an unlocked Spring Galaxy S5 g900p which I was using with Vodafone AU on 4G.

Last night I updated to the latest g900p firmware using Odin to get the stagefright patch and afterwards I am only getting 3G. The "Global" network mode is gone and was replaced with "Automatic." Is there a way in the system where I can re-enable "Global" or atleast LTE Band 3? I am rooted with the latest stock firmware.

Any help is appreciated.

Thanks.
