I'm using the 2.66 hidesu version with Franco r32 on my 6p. It works great. Just try the default configuration of the zip first. That will set you up as "eng" as described in the op. If you're unencrypted though, make sure to edit the config.txt in the superuser.zip to "nocrypt".Holy **** open source root app. I was paranoid all day yesterday after flashing SuperSU just to handle franco kernel parameters. I want to try this new superuser. I noticed there are four modes. Which modes resembles SuperSU default behavior?
