Hi, I have had the same problem last night, I was trying to install cwm recovery. In odin all seems to be good, but when the device restarts, entered in a infinite recovery boot loop. To resolve the problem, what I done is the next:
1- Remove battery.
2- Remove microsd.
3- Remove sim.
4- Wait 5 minutes.
6- Insert battery.
7- Start note 3 directly in download mode (vol down + home + power)
8- Flash original room with boot loader ticked in odin.
Hope that this can help you.
