Note 4 looping on first start up screen

Hoping for some advice how to get Sprint Note 4 running again. The phone has never been rooted. Up until a couple of weeks ago most of the OTA updates had been received and applied no problem. A couple of weeks ago my wife pulled it out of her bag and showed me it was on the update screen and had been for a couple of hours eventually the batter went dead. We took out the dead battery charged it and tried to restart. It goes to the Samsung Galaxy Note 4 white on black screen vibrates twice then the screen goes black and it repeats the same thing over and over.
Now i'm not sure how to proceed. I'm familiar with Odin and rooting my own phones but leave my wifes stock normally.

First i tried reset in recovery - When i boot to recovery after a few seconds the android robot lies on its back with a red triangle over it. At the top of the recovery screen it says Android system recovery - LRX22C.N910PVPU3BOF5. I tried wipe data/factory reset and wipe cache partion and rebooting but makes no difference.

I thought install official firmware manually
I put the phone in download mode it displays
current binary: samsung official
system status: official
reactivation lock: off
knox warranty void: 0x0
I downloaded a stock firmware N910PVPU3BOF5_N910PSPT3BOF5_N910PVPU3BOF5_HOME.tar .md5
installed Odin3 v3.10.6.exe
installed F/W this using Odin.
Odin finishes normally, box turns green and PASS! but the phone just restarts and does the boot looping thing.

I don't know what to do next - suggestions? Thanks
