Done it through KIES.
Was on Hong Kong stock firmware.
Live in London but gave my phone to family member in China (holidaying in China at the moment).
Flashed Chinese firmware for them last week.
Just updated today through KIES.
OTA was saying try later server busy or something like that to wait for my turn or something. (message was in Chinese)
Didn't try out any of the new features as I've tried them all out with LSC leak.
Now I don't own a Note so not too bothered.
