5.1.1 note 4 update put my phone back to branded

hi people

long time no speak need some help..

when i brought my note 4 (back on 4.4.4) it was a branded 3 phone and after the second day of owning it i flashed it to a official samsung 4.4.4 to get rid of the "3" branding.. anyway after the lolipop update came out my phone never asked me to update and always stated it was on the newest firmware (even up to today)

so i installed the 5.1.1 lolipop update via odin and the "3" branded stuff came back.. does anyone know where i can download a official UK unbranded 5.1.1 don't like all the branded bits

thanks in advance (im pretty sure i downloaded the unbranded firmware)

anyways any help will be appreciated
