Help Updating Binary Error

[SunMad30]

Hi,
If you trying to update the binary you get a message that says “installing please wait….if you see this message for more than five minutes, please reboot and try again”. You have waited twice, and rebooted. Anyone with a similar problem/fix? Thanks in advance. Galaxy S5 for Verizon.

You're speaking, of course, of the SuperSU app telling you that the "su" binary needs updating...

Are you actually rooted?

If so, does Root Checker (or similar app) confirm this?
