OK, so re-reading your original post, I am pretty sure I have a fix for you. Download the stock/rooted Knox-free ROM from jdsingle76 and install it. Let it "settle" for about 10 minutes after first boot-don't do anything, just let it sit and run. Go into the phone settings, update your PRL and Profile, your network info, PRL, IMEI, all that should now recognize again. Sorry as well for whatever hassle you got in order to reach this forum, looks like some members were super-helpful, and others very much not helpful. Welcome to the VM Root forums!
