    Well I gave it a try.. and it failed haha

    I could see the SDcard mounting and unmounting itself, but the exploit ran for more then 15 minutes with no reboot.

    I read that I can try reformatting my SDcard and that might fix the issue.

    I have noticed one thing though, all my apps that were stored on the SDcard are no longer available. The SDcard wasn't formatted though so I assume that the files are still on the SDcard. Does the exploit break the links between the phone and the SDcard so the phone doesn't actually know where the files for the applications exist?

    I did do a backup of my SDcard before running the exploit so hopefully everything is still there!

    will do some more reading and see if I can get it work

    cool so I got all my apps back.
    I copied my backup back to the phone and they all came back.
    They didn't all reappear right away, it took about 35-45 seconds after I rebooted the phone. (sorry I rebooted the phone after restoring everything)

    Have you tried the manual method?
    You'll get a better idea of where it's failing...

    I have not yet tested rooting the manual way, but having the APK method fail I am thinking I will give it a go.
    I am thinking it must have something to do with my SDcard. I might try formatting (now that I am confident the restore of the SDcard works) the SDcard and retrying the APK root. What I experienced is detailed as a problem by the APK's developer.

    or I might just say forget it and attempt the manual root method. Will report back my successes.. or more then likely my failures.
    ------------------------------------------------
    Hey sorry I just had a question about the manul root method compared to that of the APK

    Code:
    ** Mount your phone back to read-only (ro) access
     
     chmod 755 /system/bin
     chmod 755 /system/app 
     mount -o remount,ro -t yaffs2 /dev/block/mtdblock3 /system
    Do these two sections match up in terms of the process? Like they are both accomplishing the same thing?

    Code:
    7) Change the permission on su: chmod 4755 /system/bin/su
    8) Mount the partition as read-only: mount -o remount,ro -t yaffs2 /dev/block/mtdblock3 /system
    When these permissions are set, we are setting them back to what the default (stock) permissions are on the folders?

    Also, re-reading the APK post instructions I just noticed this:
    Code:
    Note: According to the GingerBreak source code: Before using, insert empty formatted sdcard.
    I don't know if this was previously posted, or if the post was updated to include this piece of information, but it might explain why mine failed as my card is definitely not empty!

    Problem with GingerBreak

    I appreciate all your work in putting this together. I've tried to run this a couple times and I'm having a problem. I get the files on the phone and the permissions set without any problem, but when I run GingerBreak it ends up repeating "sendmsg() failed?" over and over and never finishes. Any ideas?

    I've got a Nexus One with Android 2.3.3 Build GRI40.

    This is a listing showing the files with permissions and the results of running GingerBreak:

    Code:
    $ cd /data/local/tmp
    $ ls -l
    -rwxr-xr-x shell    shell     1062992 2011-04-21 12:58 busybox
    -rw-rw-rw- shell    shell       26264 2011-04-21 12:58 su
    -rw-rw-rw- shell    shell      196521 2011-04-21 12:58 Superuser.apk
    -rwx------ shell    shell       16830 2011-04-21 12:58 GingerBreak
    $ ./GingerBreak

    That last line will keep repeating as long as I want to let it run. Any help would be appreciated.

    Sorry Mike, but I'm not familiar enough with the binary to know how it works...

    GingerBreak sndmsg failed solved

    Thanks anyway. I found the solution elsewhere. For anyone who needs it here's what I did. I powered off my phone, took out the SD card and put in another SD card. The one I took out had quite a few things on it. The one I put it was almost empty. I was expecting to have to format it, but I tried running GingerBreak without reformatting the card. Everything worked and I got root! Then I powered off again and put the original card back in and powered the phone back on. Everything looks great.

    Thanks again,
    Mike

    Glad you got it working Mike, and thanks for posting the tip. I successfully used the apk a few times (testing), and I have about 10 gigs of data on my SD...

    Good to know for others though! xD

    I ended up having put in a blank sdcard as well. I put it in and ran the apk root again and it only took about 10 seconds.

    Thanks for the help danger-rat
