Major half root issue

    (I have the LG L45C) Ok, so I rooted this phone. It was working fine but I had an issue with the notification light going off when it wasn't supposed to, so I factory reset the phone. Now my root won't work right. An app asks for root, and it is granted but the app will tell me root failed. Root checker says I don't have proper root. So I tried re-rooting with unlock root (the only tool I can use for this phone to root) and it says failed to chmod file: rootutility. An unroot gives the same message. I tried a hard factory reset several times. There are no custom recoveries for this phone. Please help me get root back.

    Try downloading a terminal emulator and typing in: su
    Then hit the enter key (the key on the bottom right).
    Let me know what you see after hitting the enter key.

    Nothing. It prompts me, I hit allow, and it says root was granted as usual but there is no output. but none of my root apps say they have root. None of them do what they are supposed to.

    What did you see right after the su, after you granted the terminal emulator access? Did you see a $ or a #? This is important.

    But NONE of my root apps work!! They all say they don't have root!!! If I download any root app, it doesn't work like its used to. Even a factory reset doesn't help. Any root app I get says, that it is not detecting root.

    Slow down. A # means that you do have root.

    Did you go to the Play Store and update the Superuser app?

    I noticed that the permission of su didn't get changed.

    Did you install BusyBox? Some rooted apps require the binaries that are a part of BusyBox.
    You will need to go to the Play Store and download a BusyBox installer. Select the install location of /system/bin. If it fails (it does on quite a few LG phones), select the alternate install location of /system/xbin.

    Download ES file explorer from the Play Store. We are going to see what's up with su first.
    In the ES app go to the menu/settings and select file settings. Select "Show Hidden Files". Go to View and select "Details".
    Now select the star, then the phone screen. This will get you to the root directory.
    Scroll down to "system" and select it. Then select "bin". Scroll down to su and tell me what the permissions are next to it ,they should be rwxr-xr-x or rwsr-sr-x. If not, we will need to change them using the terminal emulator and shell commands (unless they are: rwxrwxrwx)

    busybox will not install anywhere. It fails no matter which I choose. bin or xbin. I can't get root with es file explorer. It fails and then disables the check button for it. All it says for the permissons on su is that they are: readable: yes, writeable: no, hidden: no. I am unable to change them as es thinks I have no root.

    Will have to change the permissions with the Terminal Emulator. Let me double check the code for that.

    chmod yields not found by the way in case your wondering.
  12. ninadchaudhari

    ninadchaudhari What's up !

    did you try chmod to /system/bin/su and /system/xbin/su ?
    may be the software you use must have pasted the binary to bin or xbin

    try in both directories :)

    Try chown 0:0 also
    I think chown will solve the issue ;)
  13. spark1223

    spark1223 Member

    chmod is in the directory /system/bin but in terminal yeilds not found. Chown 0:0 says that i'm using the command wrong

    Now that its been chowned. SU is dening super user rights to all apps. I still can't re-root

    Maybe updating the binary with the 3.0.3.2 will work or just re-installing it if it's already 3.0.3.2. Let me check on that?
    You not full bricked yet, lets see if we can get it straight. Will double check and see how to go about doing this. I saved mine 10 months ago when I lost su, got to remember how?

    The problem is I dont have chmod working right or root. Now root is dening everything.

    Well at lest you not bricked, which can happen when you do the factory reset on a rooted phone. It's not going to be easy to get your root back. Just take you time and I'll help research it. It may take a few days, just don't get impatient and do something that will brick the phone good.
    I speak from experience. My first smart phone is sitting in eye sight, a mere paper weight because I was impatient.
    I would not attempt to use any app or utility that requires root until your sure of what will happen. At lest until you can get root again.

    How do I brick the phone, without physically breaking it of course. Do not ask why I want to do this. keep in mind I cant root

    AndyOpie150 <strong> <a href="http://androidforums.com/optimus Contributor

    It's when you try to do something the CPU and mother board can't handle. It locks it up, then it will only turn on and can't get past the splash screen or the boot loader. Effectively turning it into a phone as useless as a brick.

    Do you know how to run shell commands from the PC? If your already set up with ADB and have the phone plugged into the PC, then once in the shell and you have a # after typing in adb shell, type in this:
    mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system (hit the return key)
    chmod 6755 /bin/su (hit the enter key)
    mount -o remount,ro -t yaffs2 /dev/mtdblock1 /system (hit the enter key)
    exit (hit the enter key)

    This should change the permissions of the su back to rwsr-sr-x
    then see if the apps will work.

    Douh! I totally forgot. If none of that works try downloading su update fixer from the market. It might just work.
  21. spark1223

    spark1223 Member

    Thanks man, for trying. I think this thing is totally botched. I have tried su update fixer, and it can't run chmod even in a adb shell. mount is also missing it seems. or something. It says permission denied. It seems I can't run any command in any shell. Its even denying root in terminal now.

    Try to re-root with the proper root exploit for your phone? It might work this time as your root is pretty well hosed, from doing the factory reset. Even more so now than when you first did a re-root.
  23. spark1223

    spark1223 Member

    Yeah, I still cannot root. I get cannot chmod file every time. Exact error: (cannot Chmod file: rootutility) program: unlockroot.com. Superoneclick fails as well. So do like 10 others.

    OK, try not to use any rooted app as it might cause you system to crash, and then you really have a brick. Do not factory reset again or you will have a brick.
    I'll have to call in some Big Guns to help.

    What are these big guns? can you get me the default kdz flash file for the LG-L45C?
