[AT&T LG G2] blastagator:
Want to know exactly what's missing?

I zipped up a file with all the stuff I took out (except the d802 files, because no one on d800 needs those!). It is NOT flashable, it merely contains all of the files. I preserved all of the file permissions, selinux, etc. To properly extract:

tar --selinux --xattrs --acls --same-owner --preserve-permissions -xf [FILENAME.tar] -C [OUTPUT DIRECTORY]

(Substitute the file name and output directory, without the brackets.)
