    Anyone know the link for line instructions to unroot D2? We did the simple PC method on XDA. Was a few lines of linux. Want to just unroot now for a warranty turn in. Thanks.

    I used this from the sticky.

    - open your trusty terminal app
    - you should see a $ symbol, now do the following
    - su
    - now you should see a # symbol
    - mount -o rw,remount -t ext3 /dev/block/mmcblk1p21 /system
    - rm /system/app/Superuser.apk
    - rm /system/bin/su
    * rm /system/bin/busybox
    - mount -o ro,remount -t ext3 /dev/block/mmcblk1p21 /system
    - reboot your phone. Toda, no more root

    keep getting:

    $ su
    su
    Permission denied

    been so long since I rooted a phone can't remember what the right combination was to get in there. it took many tries of turning debugging on/off trying different usb connection mode. man, I' just trying to unroot this for a friend who's camera is busted.

    If su isn't working, what makes you think it's rooted?

    Getting permission denied on the su implies that it is not rooted.

    I saw a thread about removing the superuser icon after removing root access. You could search for that to see how it turned out.

    Using the no PC method there is no tools folder. I don't know what method you used to root. The no PC method is the only one I've used.

    pool_shark is correct, if you type su and get permission denied, you are not rooted any more.

    I know pool_shark does not like to use the computer, but in this case, if this happened to me, I would plug the phone into the computer go into PC Mode:
    adb devices
    ya see your phone then
    adb shell
    if you get $ prompt you are not rooted.
    But try: (you can do stuff on computer that you can not in the emulator)
    cd /system/bin
    ls -l su
    if you get the permissions and file size, then the file must have been corrupted. Then
    rm su
    rm busybox
    cd /system/app
    rm superuser.apk
    and you will be unrooted. Turn your phone off and then back on.

    if you type ls -l su and get a "file not found" then type ls -l busybox. if it is there, type rm busybox and then cd /system/app, rm superuser.apk. Turn you phone off then back on.

    Then I would be scratching my head wondering how I got unrooted and not know it which would cause me to use my bootstrapper to restore my phone or flash the sbf to make sure I fixed it.

    You can't do it without root.
