    I have rooted my phone and am using the wireless tethering and can use other rooted apps. But when I try to use the adb shell and the su command, I am getting Permission Denied. Anybody know what the hell is happening? I am rooted using the Droid 2 method with the 2.2 OTA updae. Please help.

    Well I found why I couldn't use the su in the command prompt. It seems that I had to allow permissions in the superuser to allow the computer to use the su command. Very wierd. But I can't mount the system folder. Still need help.

    if you go into your superuser app is there an app called unknown?

    If there is click on it then click forget. Then try again in ADB and see if you get an allow deny superuser popup on your phone. Assuming you do hit allow and you should be good to go from there.

    are you trying to mount /system with adb remount? If so and thats not working cause it often doesnt try this.

    adb shell
    su
    mount -o rw,remount -t ext3 /dev/block/mmcblk1p21 /system


    Then we you want to mount as ro do this

    adb shell
    su
    mount -o ro,remount -t ext3 /dev/block/mmcblk1p21 /system

    I got that part working but why am I still unable to use the adb remount command? It just says remount failed: Peration not permitted.

    Will that then allow me to use the adb push commands? I am trying to do this for the build.props

    Perfect. Now I want to make sure I have this correct. I need to mount the system with rw then exit and use the push. Once I am done then I need to go back in and mount it as ro. Is that correct?

    Sounds like you aren't in your adb tools folder
