Samsung Note Pro 12.2 p907A - Can I overwrite the AT&T firmware?

[SebTheYella]

Hi I just received the AT&T version of this tablet but I live in the UK so would like to remove the AT&T branding and software stuff and replace it with a more stock experience. And also Lollipop if possible. Is this possible? And will it affect the ability to use LTE?

I should also clarify that although AT&T has apparently rolled out Lolipop on this device, for some reason when I search for an update it tells me that my latest (4.4) is the most recent version. But regardless, I would still like to overwrite it with non-branded firmware if possible.

You can root it if it is still on android 4.4 but so far the bootloader has not been unlocked on the carrier models so you could not install a custom rom.
with root access you can remove the AT&T extras but you would still have a rooted stock touchwiz rom.
