Rooted the phone, decided I didn't really care or need to have a phone rooted. Phone was fine. So I decided to grab the stock ATT firmware and reload it via Odin. All goes well until the very end when the phone tells me:
SECURE CHECK FAIL : system
Pretty sure this is related to the locked boot-loader. I cannot get into recovery mode, and I cannot boot into regular android, but I can get into download mode. It just fails after nearly completing everything using different Odin versions, and I've used two different firmware files. I was on 4.4.2 and had all of the latest ATT OTA updates.
Everything is still listed as official and KNOX is 0x0 and KNOX Warranty void is 0x0. I guess Kies emergency firmware recovery doesn't work with the Note 3.
