Lost root after OTA?

[B-Unit]

Installed the OTA update, but am now unable to re-root my device. The D4 utility reports that I'm successfully rooted, and Superuser app still shows, but everything is denied root permissions when attempting to use. I did not unroot or install the Voodoo app before updating.

Tried a factory wipe, didn't seem to help, SU app shows immediately after wipe, D4 utility will not re-root.

dancedroid For anyone else having headaches, I downloaded the motofail exploit directly instead of using the D4 utility and am now rooted again.
