Do you mean 4.4.2 or 4.1.2?
You can unlock your bootloader with Casual No You Verizon and install any ROM made for this device.
Was your bootloader unlocked on a previous firmware? If so you might be able to get any ROM made for this device if it's still unlocked. Otherwise you cannot unlock it on 4.4.2 and are limited to ROMs that don't require custom kernels and that are based on TouchWiz, like Ditto Note 3. Ditto Note 3 is good but the wifi didn't work for me. You can install custom ROMs with Safestrap recovery. I'm about to upload a guide that goes over all this as soon as I have enough posts to do so.
