AT&T SGH-i467 and problems installing TWRP... System software not authorized by ATT??

Hi,
So I have an att branded sgh-i467 with an active att sim. I used Kingroot to root and installed Superuser. Wanted to install LineageOS 14.1 for Samsung Galaxy Note 8.0 GT-N51xx, but after I installed TWRP as the bootloader, I get the "System software not authorized by ATT" error when pressing (vol up, power, and home) to try and access the TWRP loader. Is there a way to unlock the bootloader so that I can access TWRP to flash the custom rom. I've seen a few posts where it has been done, but I am so lost right now. I read something about needing a "Loki" bootloader??? Any help will be greatly appreciated. Thank You

Don't cross post. You are basically asking the same question in two threads. But why would a ROM for GT-N51xx be useable on an SGH-i467?

Aren't they both Samsung Note 8.0s? I'm new to this, so I was under the impression that a gt-5120 was essentially an unbranded sgh-i467, so thus, if I could bypass the att bootloader with twrp then I could flash it with the 5120 rom.

Though GT-5120 is very similar to SGH-I467, the frequency bands are not exactly the same. The former is international, but the latter is for the AT&T network.
Further, GT-5120 has an earpiece and proximity sensor while SGH-I467 does NOT. To make calls with SGH-I467 you have to use either a headset or speaker phone.
