L9 P769 stuck in S/W upgrade

Flashed to V20D using offline method and wasn't quick enough moving edited bin file over to appdata phone folder so had unrooted JB.
I tried 2nd time and server stopped and now I'm stuck in s/w upgrade loop - hard reset doesn't work - pulling battery doesn't work. At this point I would love to get phone back rooted or not!

Thanks in advance.:crying:

Ok I can tell you that you are doing something wrong. You have to follow everything top the letter. Do the first post until 9 then go to the other post until ten but don't start the flash. Prepare the bin gimme and get the Linn ready while the download is working. Then you REPLACE the bin file. REPLACE THE FILE. GOOD LUCK!

Pull battery out then hold the volume up key while inserting in computer. Load the full kdz file to get your phone running again. Then try to root by following each and e every step. Good luck.

I wish I could start over but phone is stuck in s/w upgrade mode and hard reset and removing battery doesnt work. If I try to flash again cannot do all the steps because in s/w upgrade mode and it fails.

 

[Nathan.7118391]

no no no, you are not going to do it again it's too late for that. What you are going to do is flash the kdz file in sw mode to get the phone working again. You should have non rooted jb after that. Then you try again with rooting. Good luck.

I tried to flash kdz file and had all 3 devices showing in manager so I knew drivers were loaded. Then the update tool shows "0-NotConnected 1-normal connect success 2-Emergency connect success" followed by "usb cable and your cellphone are not connected, connect wait and retry"

Try to restart computer and use another USB jack.

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://xdaforums.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.

This is the old method and was patched by LG when p769g (not sure what the p760 was) came out.
You need to do a kdz flash and swap a bin file while flashing to gain root

Then I installed custom CWM from the following link

http://xdaforums.com/showthread.php?t=2095825

I am not claiming any credit for this but would like to thank the developers of above link.

Please remember in the first link when you are rooting using the Lelus method the problem is unzipping the webserver. Your antivirius will now allow it. I was not sure if I can take a chance on running a unzip without the antivirus running. So I got around this issue by working on a windows Vmware Virtual machine. This way I was not worried even if the VM goes kaput.

Also so far rooting was the most difficult. But with patience it works. Also please read everything. Better safe then sorry.

But after that it worked just fine.

After rooting you need to install the CWM as guided in the second link.

After that for basic upgrade to Jelly Bean you can restore from any of the backups from (based on your model)

I restored it to V20D P769 by Tablechair (551.2 MB) from post
So now I have JB on my phone.

P769 Security error

That's because you already have the lastest version... You can try with KDZ..
Download a firmware from here http://lg-phone-firmware.com/index.php?id_mod=18
I found some info on the net:

1. Disable lg virtual modem in device manager
2. Boot the phone in S/W Upgrade (connected to the pc).
3. Start Windows Enabler and put the icon on "ON".
3. Open kdz in xp compatibility mode (if you are on windows 7).
4. Use type 3GQCT and PhoneMode CS_EMERGENCY in kdz.
5. Select your firmware (.kzd file)
5. Start the update.

I am having this same problem. (tmobile p769) I was on v20f firmware with L9 Recovery Installer by Artas182x. I tried to install this
http://xdaforums.com/showthread.php?t=2546357
using the [ROOT]Recovery Tools - Flasher on that same page. Well as soon as the phone rebooted I got the security error message.
I managed to get into software update screen and flash a copy of v20D that I had and then installed my L9 Recovery installer.
When I rebooted the phone I could not get into the recovery. The lights flashed as normal but no recovery.
Now here is where I really screwed up. I tried reinstalling the [ROOT]Recovery Tools - Flasher again, and got the security error. I put the phone into software update again but this time the LG firmware installer tells me the phone is not connected. ADB gives me no devices attached and nothing seems to work. The computer knows something is plugged in as I hear windows recognize something being plugged in, but that's as far as it goes.
Have I killed this phone? Or is there something I can do?

No you haven't.
Look in the general section for several guides.
You need to use fastboot & offline flash or online restore method.

P769 SW Recovery

Is there any possible reason why the LGMobile update tool would READ the COM Port where the phone is listening to when in SW mode but the R&D test tool won't???
RDTool fails stating "USB or Port not found", however it really is given the fact the LGMobile tool reads it without any issues.

Thanks in advance.
