So I noobed my phone with the OTA ZVH update. Everything seems to be working, but I am no longer rooted. Superuser says: binary outdated, tap to update. When it tries to find the currently installed binary path, it says "failed to find currently installed su binary" and "update cannot continue".
I haven't been able to find anyone using google with this exact problem (after OTA update). Hoping I won't have to revert and follow the rooting ZVH instructions.
