It looks to me as though SuperSU never made it into the phone, or at least something has boogered up whatever's there. Because I don't have root access, I can't look around to see what's in the directories.

Now here comes the weird part. For laughs and grins, I installed Phone INFO *Samsung* (v. helpful app for Sammy owners) and had a look around. The Android page says "Root Existence: Yes". WTF??? I tried installing SuperSU from Play Store. Of course it installed. But when I tried to run it, I got the "no binary and SU can't install it" message. OK, time to try Joey Krim's Root Checker Pro.

It reported, "On the install the su binary wasn't installed" (well, duhhhh). RCP does report the existence of the SuperSU and SuperSU Pro that I installed from Play Store. RCP reports /system/bin/su doesn't exist. The same is true for /system/xbin/su. The binary just isn't there.

Now what?
