dunno what you mean by timestamp. We are suggesting you to look at new root method on given link and may be you are still talking about mingkee's root method.:confused:

Yes I was referring to mingkee's version. Could not tell from the thread if it would work on g firmware.

Your method worked last night. Spent hours trying to make it work on my desktop; copied all files to my netbook and tried, and it worked fine. :confused:
oh well. Thank you for the method.

my p769 already rooted on 10e. last time the ota popped for 10g. but failed during update. theres a android logo with exclamation mark. however now everytime i check for update always showed no update.
does this mean i can only do it via cwm backup restore?

Yes.

But if you don't mind loosing all data on the device you can use the KDZ root method and flash 10g.

Just use a rooted 10g backup, or better yet 11a, all the t mobile bloatware including carrierIQ is gone. Just backup all your apps with titanium backup beforehand.

What are you trying to do? The update will come back maybe once a week and keep dying during download. I want a better root method before I upgrade to 10g.

I had a similar issue; said it failed update and such, but when you check the version number the update took; the update just didn't like the root "lock".

This solution works only on V10A and V10C rootable kdz ICS roms. Find list of rootable roms with old mingkee method in this thread.

OK. Finally uploaded the P769BK /system partition: http://dl.dropbox.com/u/37466253/system.img.ext4

Good luck with that.

carmine31280, you can try the .bin & .fls firmware image that I have: http://dl.dropbox.com/u/37466253/P7...-V10e-310-260-SEP-26-2012 0[T-MOBILE USA].zip

I am worried that it is not for the T-Mobile version because the name has LGP769AT instead of LGP769BK. Use at your own risk.
You will need the LG SmartFlash tool: http://forum.xda-developers.com/showthread.php?t=1448803

If you can put your phone into "S/W Upgrade" mode we may be able to restore it. Here are the steps:

1.) Remove battery
2.) Re-insert the battery
3.) Hold the Volume Up key
4.) Plug in the USB to phone and Computer
5.) Release Volume Up key when you see "S/W Upgrade Please wait while upgrading..." message.
6.) Run the LG SmartFlash tool as the instructions on the previous link show. The page has instructions. Good luck.

If that does not work try LGFlash: http://p92x.acidhazardrom.com/guides/lg_flash_tool.html

This is the site to watch for official KDZ releases: http://lg-phone-firmware.com There is a Canadian release for our model. It won't be T-Mobile specific and won't have wifi calling built into the kernel.

Hello, I'm looking to download the bin and fls but the dropbox link is broken, is there another place I might find it? I used the search tool with no luck

Ok once you flash and it doesn't work then you have to start all over with placing the adb root l9 on your phone again. The only thing you don't have to do is download the files. Stay over and read each line. Cman and Ellis went through a lot of trial and error top get this right. You ate missing something but you have to find out what it is! Good luck.

    This is the second edit. Thanks to zanakorus33 for providing the tip for modification of the file. Since .bat is not allowed to attach, I put it up as text file.
    The following method is applied to both international version (P760) and T-Mobile US version (P769).

    Prerequisite:
    • You must install LG United Driver (simply change the phone USB mode to LG mode and install PC Suite).
    • You must enable USB debug mode (in developers option) and "unknown sources" (in security option).
      [*]You MUST disable Lookout Security (menu->applications->downloaded) and clear its data.
    • Download and unpack Root and Restore.
      http://forum.xda-developers.com/showthread.php?t=1886460

    Are you ready? Here it goes:
    • Hook up your phone and choose USB LG mode.
    • Run Root and Restore->Runme.bat.
    • (7th edit:) Download attached modified RunMe_L9.txt, rename the extension to .bat, put the file to where the original "RunMe.bat" is, and run it as "administrator" (right click the .bat file, and run as Administrator).
    • You will be prompted to restore data. Look at the phone screen and choose "restore my data" when prompted. Press a key when restoration has finished.
    • The phone will reboot. Check the terminal window and check for "(are you rooted?)" error. If there's no error, check the phone to see "Android is updating". If so, the phone should be rooted.
    • Download and install busybox and SuperSU.
    • Done.
    Happy Rooting! :victory:

    First edit: uploaded modified script file (added pause command on running restore part. Press any button after the restore has finished on the phone). Change extension from .txt to .bat (you can review the whole script before renaming to examine). Put the modified file to where RunMe.bat is and run it.
    Please give me feedback of this script file.

    Thanks zanakorus33 for giving tips for modification

    Fourth edit:
    After rooting, install Voodoo Root Keeper so you can preserve root after update.

    sixth edit:
    overthatscreen said:
    Alrighty. I went ahead thanks to your vote of confidence. It all worked out ok for me.

    Can we add to the instructions:
    1. Run the batch file as Administrator
    2. When it asks for Encryption key, just press Restore.
    3. This will work on 10E update.

    Above quote is from my PM.

    Trust me all. After the instructions of O2X Developers due to my continuous follow up, I literally found an Admin who can make SUBFORUM for LG L9 (p760, p765, p768, p769, etc) and requested him to make one as soon as possible. He replied (wow, finally) and asked me the list of links of all L9 developement related threads and posts which are scattered at various place. I quickly made a small list and sent him. Lets hope he will create one soon. Thanks in advance to Admin.

    Pray and wish us all GOODLUCK. :)

    1.) Root your device.

    2.) Download to your device "overclock.zip" from this thread:

    http://forum.xda-developers.com/showthread.php?t=1961989

    3.) Install "AndroZip File Manager" from the Play store.

    4.) Run AndroZip and browse to overclock.zip. (Probably /mnt/sdcard/Download .)

    5.) tap on the file "overclock.zip" and select "Extract file here".
    (A new directory named "overclock" is created)

    6.) Install "ES File Explorer File Manager" from the Play store.

    7.) Run ES File Explorer and press your "menu" button then select "settings".

    8.) Change these settings:

    Home Directory = /

    Root settings --> Check all boxes

    9.) Press the "back" button until the app exits.

    10.) Run ES File Explorer again.
    (Now your root partition "/" should be mounted with read/write permissions.

    11.) Browse to the overclock directory. (Probably /mnt/sdcard/Download/overclock/ .)

    12.) Long press on the cpu_control.ko file and a menu should open. Select "copy".

    13.) Browse to the /system/lib/modules/ directory .

    14.) Press "menu" button and select "Operations" then select "Paste" .

    15.) Long press on the cpu_control.ko file and a menu should open. Select "Properties".

    16.) Press "Change" and check the boxes like this:

    User: read write
    Group: read
    Other: read

    17.) Perform steps 12-17 on the symsearch.ko file which is also in the overclock directory.

    18.) Install "Rom Toolbox Lite" from the Play store.

    19.) Run ROM Toolbox Lite and select "Scripter".

    20.) Press the "+" symbol in the top right corner and select "Create" to add the overclock script.

    21.) Name it "overclock" or whaterver you wish.

    22.) In the "Commands:" field enter this:

    insmod /system/lib/modules/symsearch.ko
    insmod /system/lib/modules/cpu_control.ko

    echo 0 300 980 > /proc/cpu_control/tweak_cpu
    echo 1 600 1200 > /proc/cpu_control/tweak_cpu
    echo 2 800 1300 > /proc/cpu_control/tweak_cpu
    echo 3 1200 1370 > /proc/cpu_control/tweak_cpu

    23.) Your phone will overclock to 1.2Ghz.
    If you wish to overclock higer you can try changing 1200 in the last line to 1300 for 1.3Ghz.

    24.) Press the floppy disk in the top right corner to save the script.

    25.) Press the overclock script and a menu will open. Select "Run Script".

    If everything worked you should see an "exit valut:0" message.
    If you run the script again you will see the same value but with a warning message.
    This is normal since the modules are already loaded.

    26.) You can load a cpu monitoring app to see if the overclocking works or just create another script that displays cpu clock info.
    Here is the command for that script:

    cat /proc/cpu_control/opp_table_current

    27.) After making sure your device is stable you can have the overclock script run automatically at boot.

    Press the "overclock" script and a menu will open.
    Press "Set at boot"
    Reboot the device and you will see a notification that the script ran in the notification area of the device at top.
