I can get into cwm but everything i flash just leads me to a screen with the lg logo. Therefore, I'm trying to fast boot my phone and recover my phone but so far I've only been able to get to s/w upgrade mode and recovery stops at 15% because my computer sense that the phone isn't connected. I've tried running the recovery software in diag mode but it couldn't get past 15%. Can someone please help me?

2 options
Download LG mobile support (B2CAppSetup.exe) and select recover your phone. Your phone must be in S/W update mode and you must remove/comment LG server line in hosts file (for offline flash)
Try to use Lelus fast boot to flash ICS u-boot & x-loader (according to your phone model). And try to offline flash again. JB firmware does not work with offline flash.

What about the offline flashing method? Using a kdz file?
Sent from my LG-P760 using xda app-developers app
I did it I unbricked it with this method :
http://forum.xda-developers.com/showthread.php?t=2119090
So i got it to fastboot and then I flashed CWM with it to my Phone after that i flashed a custom rom via cwm --> Working
Now theres only one question remaining. How can i get a stock rom to the phone if this LG tool dont wirk is there a version for cwm and p760 out ?
After attepmting to root, I ended up with a "Security Error" problem. I ended up using fastboot to flash the uboot and xloader. And now since then the phone won't do anything at all. I can enter fastboot, it will even show on the screen when it enters fastboot. But I can no longer enter S/W mode, and the phone won't turn on Using the power buttons or any combinations of buttons. It just shows a blank screen if I try turning it on by holding power. I can't adb into it, and the LG Support Tool can't find the phone. How can I get S/W back at least so I can flash it or something?
It's a p769 and was previously running JB
Which x & u did you flash?
I prefer to do things manually, another thing, who's fastboot did you use? If you used Lelus select option #1 and copy the files p1ics769.bin & p2ics769.bin (found in the "xu" folder) into the "yours" folder.
When you have the inverted fastboot on your phone, type the following
fastboot devices (to check if your are connected)
fastboot flash x-loader p1ics769.bin
fastboot flash u-boot p2ics769.bin
After you do this, take out your battery and hold vol up and enter the usb cable into the pc & phone & put the battery back. If that doesn't work, enter battery, hold vol up and enter usb cable, keep trying different usb ports on your pc.
Fixed!
Flashing the u-boot and x-loader worked perfectly. Put me back at where I was originally which was the "Security Error". Then I just went back into S/W mode, and used the KDZ flash and everything works now! Thank you so much.
Just for those who have trouble, if you have the p769 with JB, and you run into "Security Error" flash the x-loader and u-boot to match ICS, then the LG tool will find your phone. Then you can just flash the JB KDZ
Did u flashed KDZ offline

HI there I am trying to flash KDZ using offline KDZ method.
I can enter into S/W mode
But it LG software does not detects phone.
It was happening me to previously too. but if we turn on USB debugging when phone was On. It was working.
But the thing is now that I am stuck into boot loop.
And in S/W mode LG tool doesnot detect phone (but I can my phone connected in Device manager)
So LG tool stops at 14%.
HELP ME OUT PLEASE.
So I recently wanted to load a custom rom on my p769.
Unfortunately, I tried to flash a rom without actually having the bootloader unlocked (thought i did?)
Now i'm forever stuck at the "LG Security Error" screen.
I can't seem to do anything else! :'(
The only other mode I can boot into is S/W update screen (holding volume up and plugging in usb cable).
I tried to get to another mode I read about (vol up + vol down then plug usb cable for "download" mode, to no avail)
Anyway, once I do get it into sw update mode, I can't seem to do anything either way, when i try to list adb devices, none are listed, when i try to use lg mobile tool, it never connects, when i try to use kdz offline update tool, it doesn't see the phone, it just keeps trying to connect, the log freaks out at "_IsConnectedPhone Call", and just keeps trying to "connect" to phone but can't
Am I totally screwed here?
What can I do? Any help appreciated!

You're on JB, right? KDZ offline flash tool cannot detect phone in JB. you have to flash ICS x-loader/u-boot then that tool can detect your phone. please visit http://forum.xda-developers.com/showthread.php?t=2292828
For LG mobile support tool problem, it need to download rom from LG server. Have you remove/comment 1-2 line that you add to hosts file? You said it never connect that mean it don't see your phone?

I've tried this as well, but I don't know if i'm doing it correctly
I installed the 'drivers' it needs (following the readme file) when it shows the "unknown/other" device (the part where you have to catch it in device manager).
After this, I run the start.bat, enter 5 and hit enter, i unplug my phone and hit any key, then i plug it in as it says and it does it's thing, then i wait for 4 seconds when it begins to say "waiting for device", i put my battery in and it just stays there, waiting for device
Can you help me figure this out? Am I doing something wrong?

i think i'm making some progress, thanks for helping so far!
anyway, i'm able to get fastboot on my phone (i think?), the screen on the phone shows the flipped LG logo and at the top right it says 2.0 fastboot (flipped of course)
but, what am i supposed to do here?
i see the 2 omap devices listed on my device manager
whenever i try to run the kdz offline flash tool (if i'm using the right one), it still doesn't detect the phone as connected, doesn't even try, just errors and tells me to connect to usb port and restart or exit
what am i supposed to do once i'm in fastboot recovery for my phone?
should i comment out the 2 listings i added to the hosts file? should i NOT be running shttps app? which kdz offline flash tool should i be using? (currently trying: UpTestEX_mod2_marwin.exe)

You should run start.bat and select flash ICS u-boot/x-loader for P769
When it finish, reboot you phone to S/W update mode and try to use UpTestEX_mod2_marwin.exe to flash your P769 kdz again to restore your phone.
Maybe I miss something about P769 model, please search in FAQ forum many people have this issue, and most of them have fixed it.

S/W update mode is enough to do offline flash your kdz or recovery your phone via LG mobile support tools. Please select one of those 2 methods to recover your phone.
You need to unlock bootloader before install custom rom or recovery.
Take the kdz files from cmahendra's thread and use S/W mode to flash it.
Please don't forget to unlock your boot loader next time.
Good evening, I have in my hands a smartphone lg p778g does not pass me the logo to light following a simple copy of the folder whatsapp internal memory to the microsd (it was blocked after you copy and to restart it and did not initiate more ... it stays in the LG logo when turned on and there does not pass.
I tried to hard reset with vol (+ or -) buttons + home + power but rather than get out the menu of recovery I get the doll android slept with a triangle exclamation and there is no way to enter the menu that tightening no buttons.
Then I looking for information online found the utility tool flash, did all the steps as marked, I installed the drivers perfectly, the PC detects me the phone without problems, but always in the middle of the update (put the mobile mode s / w upgrade ) 50% program lg cancel the process by saying that there has been an unknown error and try try again by disconnecting and connecting the mobile, but no way, I give retry to to try again and again it hangs at 50% and I jump the error screen again.
I wonder if there is some other program where you can do the hard reset this phone than by the official LG utility, or by microsd.
The operating system used is Windows 7 64-bit, disable the Windows firewall and antivirus and run as administrator utility tool flash lg 2014, but always the same. I also tried running the utility lg mobile support tool directly to you directly seeking the most updated for lg p778g firmware, but it's the same as using the lg flash tool 2014, the 50% of the upgrade stops and gives me the message error.
A greeting and I hope you can help me, I need the phone !!
We'd need someone with a p778g. The problem may be be caused by the special branding of the phone, or an encrypted bootloader. Or the internal flash got completely cleared, partitions and baseband rom, which means a full brick. Otherwise flashing stock in D/L mode should work, even if anything else fails. But this goes mainly for LGs official tool working online. With the LG Flash Tool 2014 i had also problems.
I think both tools have to ways to perform the unbricking. Either with the phone put in D/L mode by the user (if Fastboot don't work on the PC), or by recognizing the phone (but with a still running system) via ADB, then auto-switching to Fastboot. And you should also be able to attach the phone when it's already in Fastboot mode. The latter methods don't work on both my systems under Win10. When my desktop pc had been upgraded to 8.1, i performed all servicing of the L9 with my netbook, which was still on Seven.
My last unbrick was months ago, and i don' t know what happens at 50%. It's something important, and knowing it may help to understand the nature of the problem(loss of contact between phone and pc before the actual process starts, errors during flashing...).
It could be like this:
-phone seems to get recognized by driver&tool, that is good
-image gets downloaded(only with the official tool)
-image gets temporarily extracted on the pc(both online and offline). I fear that by completing the extraction the 50% mark is reached, and that no actual writes to the phone can be performed.
And LG's stock recovery, which calls itself "service mode" or "s/w mode" can be mistaken for D/L mode. I'm talking about the D/L mode, which is also present with a custom recovery, but theoretically D/L mode, S/W mode and Fastboot could be used for unbricking
