    This is a known issue with many applications for Android. The best way to fix it is to install busybox (instructions and download here): Busybox for android then the fix_Permissions script (download here): http://n0rp.chemlab.org/android/fix_permissions.sh

    Pretty much anytime you install a program, just to be safe, run Terminal and enter the command fix_permissions. It seems to correct a lot of problems. Hope this helps.

    your phone wasnt bricked....if you would have doen a factory reset, then after the reboot you would have been back to normal.

    to everyone, if you dont know what your doing or dont know what it means to root then do not do this.

    bought my wife this phone a few weeks ago.....trying to win one for myself, its pretty decent :)

    to mygti02.. I did do a factory reset and I did the hard reset as well. Sorry I am not a know it all. After all isnt that what this forum is about? To learn and exchange info?
     
  4. I am a programmer with experience with Linux and Java, but I am new to the android community as this is my first phone. Let me know if I can help in any way.

    I have 2 rooted G1's and won a Behold II, should be here in about 10 days. Is there a recovery image that works on it yet? Is permanent root and custom roms an option yet? I am a mod on Android Community and we don't have nearly as much information on the Behod II as you do here. Thanks in advance for your indulgence.

    The behold runs a check on boot an removes suid shells in /bin (and probably other directories. We need to hijack a suid task that runs really early on to get persistant root (see first post).

    The behold also uses some secure partitions and so you cant simply use fastboot or odin to flash a custom recovery. Its also not security ulocked :(

    The only way to put a custom rom on it would be to get the hijacked persisitant root command to kill system processes, untar onto /system what you need and then retart the processes.

    Everyone be warned.. a 'hard reset' or 'factory restore' ONLY wipes /data and cache. That means any changes you make to /system will remain after a factory reset, except any that get undone on boot (like the su). On the upside it means you could probably untar a modified system onto /system and most of it would remain. On the down side if you mess up your /system you're phone is essentially bricked untill we get at least one update from samsung.

    Thank you for myour response, I think I'll sell it and get the Nexus One on the 5th of January. It won't be long until it gets rooted. I've already looked at the system dump and seen the boot screen. Thanks again.

    This does not work for me. I gain the initial root and setup everything but the root does not stick. After a reboot su in the adb shell brings me back to $ not #.

    No error messages or anything else I can see.

    Below is my playlogo

    $ cat /system/bin/playlogo
    cat /system/bin/playlogo
    #!/system/bin/sh
    /data/local/try3 /system/bin/sh
    mount -o rw,remount /dev/st9 /system
    cat /system/bin/sh > /system/bin/su
    chmod 04755 /system/bin/su
    /system/bin/playlogo_real

    It means you can ditch the stupid touchwiz, and use stock android.

    It also means custom roms :)

    Is this running 1.5? Wow, this is so fantastic! I have been waiting since before the phone even came out to hear this news!! BTW, I am definitely donating to the 2.x cause.

    Thank you all so much for your diligent efforts!

    I always seem to have about 115mb of ram free when I first boot and close anything unnecessary with a task killer (like myfave which takes up like 10mb and is a service I don't have). If it stays like that after an hour though big props and I can't wait for this.

    Count me more interested when there is a way to go back or restore the original image. Other then that i continue to wait for the update. Its kinda like Christmas with a mix of eagerness knowing its coming and angst not knowing how long.
