Did you back up your stock rom. I think it will do because it will erase everything event your internal file. After that you can root and install twrp.

So I have to go back to stock rom before I can flash 4.4.3 custom rom? What about do I need to update the bootloader?

Restore to stock, plug your n7 to computer and make sure you have unlock boot loader, install n7 driver with adb , turn on USB debuting, and open the latest wugfresh root tool kit. Choose your firmware which is ktu84l n7 wifi. Find flash stock and unroot button. It will request you to download factory img. If you already download then proceed to flash. it will take a while just be patient. If done you can rooted back, just choose root with custom recovery.
Guys correct me if I am wrong, this is my personal experience.
