Yes, of course... All retail Moto's on Marshmallow have an unlockable bootloader and are rootable. Just do your homework, the new systemless method will make life much easier than it was over a year ago.
A link in my signature may help (hint, hint)
Yep, mine came with the May security and was able to root and unlock bootloader
Thanks for your help guys.

It seems to be a 2017 model that was announced in 2016 from what I've seen so far.
There are no stock ROMs on sammobile so far so your best bet for getting a copy of the stock would be either using the official Samsung recovery software or getting it from another user with the same exact phone.

How to harden current stock image against the current Bluetooth exploit

I just did a scan with the BlueBorne Vulnerability Scanner on all my devices, my s5 neo is vulnerable for the exploit (my s6 too).
I'm on stock 6.0.1 MMB29K.G903FXXU1BQC1 , security patch level is july 1st 2017 . Is there a way to patch the exploit myself via adb? I need bluetooth for various headsets, so never using bluetooth again is no option.
I do hope to get some kind of official security patch in the next ?? months, but as the s5 and s5 plus were already served with security patches I'm not sure, no love for the s5 neo I guess

Root possible for SM-G950U on Nougat 7.0?

I remember the issues with the locked snapdragon bootloader on the G950U when I was looking to root back around 2017, and talks about it maybe being possible. Fast forward several years and I haven't really looked into it ever since, and searches are giving me a mixed bag of answers. I am still on the old Dec 1, 2017 patch on nougat 7.0, would be nice to get onto 9.0 with root, but I'd be happy to stick with 7.0 or 8.0 if it means having a root. Have been holding out from upgrading for a long time in hopes that maybe something would come along, but if there still isn't something available for the Dec 2017 patch after all this time guess I'll just bite the bullet on the updates and look into an upgrade
