ATT Galaxy Note 2 stuck on Galaxy boot screen
So I have a problem with it staying on the Samsung screen. Samsung does change colors from white to blue/purple and back. Just keeps doing this. I have let sit for 10 minutes. I will explain what I did to get it here and what I have done to try and fix.
Phone was rooted 4.3. Upgrade came, tried to install and it would fail. Did research and found out I needed to unroot. Went into Supersu and unrooted that way. Rebooted and no root. Did upgrade to 4.4 and it got stuck on the AT&T screen for about 15 minutes. Pulled battery and got same result stuck at AT&T screen.
Tried to go into recovery and it would not. Downloaded a ATT 4.1.1 firmware and used odin 3.07. Got the Pass and got stuck on Samsung screen. I have gone into recovery mode and wiped data factory reset and cleared cache.
Still no results. Does anyone else have anything else I can try? All research I have done tells me I may be screwed.
