    What would cause this to happen? I did the reset, but it's still there. Do I need to erase the phone's internal storage or something?

    You have to unroot and uninstall the SU app. Otherwise it wont go away. The SU app installs as a system app that's why it wont go away with a FDR.

    What utility or process did you use to root your phone? Just curious because depending on how you rooted your phone, there may be some things you would do differently. I am familiar with Matt L Groff's utility 1.8 or 1.81.

    Do you have voodoo root keeper installed? Use that to unroot then as jstafford mentions in the second post uninstall superuser from your phone's root directory.

    If I'm not mistaken, Rootkeeper only saves a backup of Superuser, so if you "Temp Unroot" to take an OTA, I believe it saves SU somewhere else in the phone, and then restores it when you re-root. But it doesn't delete it.

    I used Matt's utilities to root my phone. It doesn't get any easier. :)

    Oops, my bad... my instructions are in reverse. Superuser is installed in the root directory and can not be uninstalled through typical means (like an uninstall button). So he would have to be rooted then go into the root directory of the phone to delete the superuser apk and then unroot using voodoo root keeper.

    From voodoo root keeper, there is an option to delete SU backup. I believe this will get rid of the SU app itself but not certain. Then choose to unroot.

    Thanks, worked like a charm. Should I do a factory reset to start off with clean razr maxx? Then root with Droid RAZR Utility 1.8 after I install everything again?

    A factory reset is always a good thing, especially after something like this. Just be sure to back up anything you want to save, like contacts, texts, pics and videos. :)

    Wait, let me back track. It did unroot the phone, but the super user is still there. I can't find any options for the SU delete.

    The only way to delete the superuser.apk is with a file explorer like "Root Explorer" ... (which requires root) ... go into /system/app and delete superuser.apk (if it tells you that it can't delete because it's read only, you will see a box that says "Mount R/W" ... tap that and then delete the .apk :)

    EDIT: "Root Browser Lite" is a free app. Root Explorer is a paid app. Both will delete SU

    Then reboot after you delete it.

    Make sure you are still rooted. (All the boxes are checked in Rootkeeper)

    Use the file manager to delete the .apk

    Then reboot the phone and unroot with Rootkeeper. That should do it. :)

    Ok, worked I'm back to stock. Should I root it then add voodoo or the other way around? Also what is the difference between 211 and 215 and should I go to 215? Thanks!

    .215 is much better than .211 ... just about everyone who has gone to .215 has noticed improvements, especially with battery life. (But everyone's phone is used differently)

    If you are on .211 now, you have a choice. You can root, unroot with Rootkeeper, and restore root with Rootkeeper after going to .215, or you can go to .215 and root after using Matt's 1.8 Utility. That's up to you.

    Here is everything you need to know about .215 in this thread:

    E
    DIT: If you are stock .211 and not rooted you will do course #1 to get to .215. Read the entire first post! :)
