Phone stuck on "Recovery is not seandroid enforcing" - Sprint 5.1.1 G920P Galaxy S6

I thought that after waiting nearly 2 full years of having my Sprint Galaxy S6 G920P droid version G920PVPU2BOF7 on Droid 5.1.1 that I'd be able to "easily" root it and then ROM it or put recovery on it etc.. whatever... and as it seems that was far from the case. I backed up "most of the phone" and realized when its too late that I missed a couple things.

Anyways, is there no way back from this "Recovery is not seandroid enforcing" to get into the UI for 5.1.1 OS to resume normalcy, other than to use ODIN to restore to a factory stock ROM?

Would you at this point instead restore to a Rooted rom?

If so, what is a good one that ya'll feel will work on the first shot?

I can't believe how much trouble I had rooting it or finding a good reliable root. I must not know where to look. Should I have started at CWM, CF or TWRP instead of googling around?

First time I tried, I lost all networking abilities. I wish now I had "backed up the stock Kernel somehow" before experimenting.

Right after that I got networking back trying a different 2nd Kernel root, but on boot it said "kernel is not seandroid enforcing", then the phone would start normally except for this "Unfortunately NetworkSystemProvider has stopped." popup that constantly was in my way and wouldn't allow me to get rid of it permanently. I could "OK" it away for 1 second to tap other things between it popping up and then I was able to shut the phone down for another root try with what I hoped would be the right Kernel.

On the 3rd attempt I got this "recovery is not seandroid enforcing" at the boot screen and accompanied with an infinite reboot loop where I could still see the Samsung and Android logo etc.. black screen. Loading to the stock recovery or stock bootloader preboot menu system no longer worked (up arrow + home + power) either.

Now I've got it at the downloading bluish screen waiting for me to either flash it with another Kernel (that I can only HOPE will work) or to completely wipe it out and reflash stock firmware or one that ya'll tell me will be worth trying.

This is very aggravating because I have 20 years of I.T. experience under my belt, but the resources on the web have gotten very difficult to navigate with so many ads, popups and CPU consuming pages while I'm trying to read.... its insane. I finally caved in and downloaded a stock rom from stockroms.net and sammobile.com (1 from each to compare) and I'm waiting before I wipe the phone out to see if there is a way to get it to boot again without wiping my data.

Any way to navigate the phone and mount it via USB to grab files before I wipe it?

Here's the phone info I was able to get off the About screen before I soft-bricked it:
