Samsung N910F with N910T bootloader and N910F CSC?! can't upgrade to Lollipop help!!

Hello all I just recently purchased a Galaxy Note 4 and I'm trying to install lollipop via ODIN but it keeps failing I think partly because the bootloader shows up as N910T when the phone model is actually N910F european model that was bought in the UK obviously the phoned has been tampered with in the past and I would like to change the bootloader and baseband which are both N910T to N910F however the CSC shows up as N910FXXU1ANK4 i don't understand this?. Bootloader version is N910TUVU1ANJ7? the phone thinks it is the US T-Mobile Variant im guessing somebody screwed it up in the past? anyhow I need to be able to flash N910F 5.1.1 Lollipop to the phone but it always results in FAIL!(Auth) in Odin v3.0.9 .

N910T 5.1.1 Notification Sound Screen of Death

I have an issue with 5.1.1 kernels (both Emotion and AEL kernels) on the N910T. It only happens when I have the notification sound on and I receive a notification while my screen is off. The phone vibrates once or twice and then doesn't wake up. The LED will flash blue repeatedly but the phone is essentially dead till I pull the battery out. I never have issues otherwise when the phone is set to mute or vibrate.

Has anyone else noticed this also and anyone have any fixes?
