Got to say thank you since now my note 3 is rooted.
Initially confused between rom and kernel as i've downloaded the roms (yes, both XXUEND3 and XXUFNF4 as i downloaded them before for other method of rooting), flashing and failed to get root for the device. Then I notice the word kernel there after carefully reading post #1.
Hope this is lesson learned for others as well.
Big thanks again to _alexndr.
