[Q] Set Warranty Bit: Kernel...no boot topic

Hi All, I currently have wicked rom on my note 3 tmobile, but I have tried to flash 2 different Roms, and after flash I get the "Set Warranty Bit: Kernel" message at the top of screen, but I dont get anything else...there is nothing else about seandroid or whatever, I do get the Samsung logo but It just sits there. I have TWRP installed 2.6.3 I believe it is, I'm new to this phone and the terminology etc, but I just cant get anywhere with it. Im guessing it has something to do with my phone still having Android 4.3 on it? SM-N900T is the model....can someone enlighten me on this?....I'd like to try a Kit Kat rom..Thanks for your time!!!!
