Is the lt03wifiue build the same as n1awifi?

n2awifi is the TabPRO 10.1. You might be referring to n1awifi (which you correctly mentioned in your other question).

Sometime during development, some Samsung devices were reassigned codenames, and lt03wifi was renamed to n1awifi (see commit here and developer note here).

No need to worry as these are still the same device, and the ROM itself has provision for the name change (it checks match for either codenames when installing).
