But Verizon can't keep the Dev Community down, and as it turns out, Adam over on XDA Forums has now come up with away around this. Yes, he is the same guy that developed the original rooting method for the device. So in essence, the software update to version I605VRALL4 that is to prevent rooting and unlocking of the phone....has been circumvented. By following Adam's instructions and downloading the required programs on your PC, you can still root and unlock the Samsung Galaxy Note II, even after Verizon's OTA software update has been installed. It also includes the TWRP Bootloader, but you can install CWM (ClockWorkMod) afterwards by using the flash file. Just keep in mind this updated root method was recently developed, and a few members on XDA have posted some issues while attempting to use the rooting programs, so continue at your own risk.

Odin307 Odin is an internal Samsung tool for use on Windows. Extract the files from this zip to your desktop and then run the program. It takes the .tar.md5.gz files, turns them into .tar.md5, and flashes them. Don't flash a PIT, you don't need it. Put the requested file into PDA for this procedure and after flashing click the reset button.
BAV Baseline This will prepare your device for the root exploit and ensure we have root access if you have not enabled any exploit blockers. You will flash this with Odin the first time CASUAL asks you to flash a file. This is a bone-stock VRALJB kernel from Samsung. Do not uncompress. This gets flashed with Odin as-is.
