I've tested this:
Extracted an NCA file, and repacked with the NCA Builder. It installs, but it gives an error when running it.
(The NCA file installs and works just fine before the unpacking and repacking)
So something is still not right I guess....
Edit: I've extracted the NCA file using hactool with the following command:
Code:hactool -x -y -k keys.dat --section0dir=NCA/section0 --section1dir=NCA/section1 --section2dir=NCA/section2 --exefsdir=NCA/exefs --romfsdir=NCA/romfs --titlekey=<TITLEKEY> <NCAFILE.nca>
What settings did you use with the builder?
