Not 100 % sure what your trying to do but there is an issue with upgrading to 4.3 where you lose your baseband ( no signal ) but it's an easy fix. The best advice I can give you is to read one of Dr ketan's guides on the subject. He is the guru on all things note 2
If you are selecting wipe to install new rom in recovery and then not installing anything that's probably the problem
