I had root on 4.2 previously, but the update lost it, and with it my ability to use Sixaxis, AdFree, some features of NFC Tools and Tasker and Xposed modules.
I have searched, but it does not appear on this list: How do I root my Android device?
I also saw a similar question here, but this is the AT&T version, not Verizon: How to root the SM-G900F Android 5.0 without tripping KNOX?
Towelroot doesn't work (just tried) and the SM-G900V isn't listed here: https://autoroot.chainfire.eu/
Anyone have any experience with this?
