First of all, I apologize for having uploaded all the figures of my post in the "figure.zip" attachment, but I was not able to insert them as separate figures using the "insert image" function. I am a new user and perhaps I am not allowed to use this function.
I am not able to recover from a "soft brick" due to an aborted flash of a stock ROM. Here is the story.
I started working with this LG phone:
Model: L9 P760 (Vodafone brand)
OS Android 4.1.2 Jelly Bean (it was previously updated form ICS through the official upgrade from LG)
SW Version: P760 20d-262-02
Kernel: 3.0.31
Build: JZ054K
Baseband: L626_MODEM_SIC_01.1230.00
My goal was to re flash with another JB stock ROM, so upgrading its release and getting an unbranded phone.
I downloaded this stock ROM kdz file: V20H_00.kdz
Then I tried to flash with a procedure derived from this one: http://forum.xda-developers.com/showthread.php?t=2085344
The main difference was related to the fact that I did not put the smartphone in S/W Upgrade status at the beginning, I connected it to USB port when it was power on and set the PhoneMode to "DIAG" instead of "EMERGENCY". The phone went in "S/W Upgrade" mode during the flash procedure.
I worked on my laptop, the operating system is Windows 7 Professional, SP1 64 bit.
A problem occurred during the update: the LG Mobile Support Tool crashed and the phone remained in "S/W upgrade" status. I restarted the LG Mobile Support Tool, but I was not able to make it continue the update. Then I disconnected the phone from USB and removed the battery. When I re inserted the battery the phone did not boot anymore.
Now my LG L9 P760 does not start pushing the normal power on button.
It does not make a factory reset if I push Power on, home and vol- buttons
There are no any combination of buttons I can start for having any reaction from my LG L9.
Then, I tried to recover from this "soft brick" status in the way I describe hereunder.
1) I removed everything related to LG from my laptop (LG Mobile tool -including LGMOBILEAX directory under C:\ProgramData- and LG drivers)
2) I installed the following LG SW:
LG drivers, rel. 3.11.3, from a file named: LGUnitedMobileDriver_S50MAN311AP22_ML_WHQL_Ver_3.11.3.exe
LG Mobile Support Tool rel. 1.7.3.0, installed through this program: B2CAppSetup.exe, running in Windows XP SP3 compatibility mode. From file properties , tab "details" I read this B2CAppSetup.exe is ver. 1.0.1.7.
3) I connected the smartphone to my laptop through the USB cable. After about 10 - 15 seconds it went in SW upgrade mode. At least, I see "S/W Upgrade - Please Wait while upgrading...." on the LG L9 screen. BTW, that occurs every time I connect the smartphone to my PC, in any cases: removing the battery or not removing it, pressing or not the vol+ button... In any cases it goes in that state.
Before connecting the smartphone, this is what Device manager showed:
[pls see devManager-phoneNotConnected.PNG in figure.zip]
After I connected the smartphone through USB, this is what Device Manager displayed:
[pls see devManager-phoneConnected.PNG in figure.zip]
Without starting the LG Mobile Support Tool I saw that after some minutes its display did not show the "S/W upgrade" message anymore, nothing was displayed. And after about 10 seconds the "S/W Upgrade.." message came back again. It is like the smartphone tried to connect to some applications running on the laptop, but did not find any process there, then it retried, and so on.
When the LG display was black, the Device manager output was like it was before connecting the smartphone to USB port. When "S/W Upgrade..." came back on the LG display, LG devices came back on Device Manager output.
4) At this point, when "S/W Upgrade.." was displayed on LG I started the LG Mobile Support Tool. It seemed it was able to recognize my smartphone, as I saw this output.
[pls see LG_MobileSupportTool-start.PNG in figure.zip]
But waiting for 1 or few minutes without doing anything the "S/W upgrade..." message disappeared on my LG display and LG Mobile Support Tool showed this output:
[pls see LG_MobileSupportTool-start01.PNG in figure.zip]
It was like the connection between the smartphone and the LG Mobile Support Tool could not be kept, or was not stable.
5) Anyway, when the connection seemed to be ok I selected the choice "Upgrade Recovery" under "Options" menu choice, and the recovery procedure started. This is the sequence output I saw on the LG Mobile Support Display:
[pls see LG_MobileSupportTool-start02.PNG in figure.zip]
[pls see LG_MobileSupportTool-start03.PNG in figure.zip]
[pls see LG_MobileSupportTool-start04.PNG in figure.zip]
But during the "Upgrading your phone..." phase, the process was always blocked at 15% of its execution (it remained at 15% for a relatively long time, let's say 2 or 3 minutes) and I read this output:
[pls see LG_MobileSupportTool-start05.PNG in figure.zip]
Now, if I retry the procedure (with or without disconnecting the phone, removing the battery and so on and the reconnecting) I get this message if I push the "retry" button when the LG display is black.
[pls see LG_MobileSupportTool-start06.PNG in figure.zip]
Otherwise, If LG display indicates "S/W Upgrade..." the procedure restarts, but always with the same result: it aborts at 15% of progress, and LG Mobile Support Tool shows the same error:
I tried a lot of alternatives avoiding to download the ROM image online from LG site. I tried the procedures I found here http://forum.xda-developers.com/showthread.php?t=2085344 and also here http://forum.xda-developers.com/showthread.php?t=2797190, where I found an interesting and more recent tool for an off line KDZ flash.
I tried to flash a couple of diferent KDZs: v20c_00.kdz -ICS- and V20H_00.kdz (JB) but always the procedure was aborted during the update.
I believe my problem should be related to 3 main factors:
Some issues on LG drivers, also if somehow my phone is detected by LG Mobile Support Tool, when I connect it via USB cable.
Some issues with the LG tools I use (or perhaps I do not configure everything needed in the right way, or perhaps there are issues with Windows 7 64 bit)
Some issues with the kdz I use. Perhaps I could adopt some othe stock ROMs (also if I have already tried with 2 different KDZ).
I tried these procedure using other PCs, another Win 7 64 bit and an XP SP3 32 bit, but basically the problem is always the same: the recovery / flash procedure is aborted at 15% of its progress.
Who could give me any advices on what could be the reason of this fault, and on what procedure I could do?
I have not tried anything related to adb or fastboot till now, as in my opinion my issue should not require these tools in order to be solved. I mean, my LG L9 easily goes in "S/W Upgrade.." mode, so it does not seem the problem is related to a boot loop status. Anyway, could a flash via fastboot solve my issue?
Pls help me, I can give you every additional details it could be useful...
Thank you in advance!

TY BajoPrimate, that thread gives me a hope!
But I still need your help. I tried that procedure, and I got an error very similar to the others described there: download failed after 6 sec..... So I tried to download the bin image for P760 that you indicated here, but the URL "http://uploaded.net/f/xh3dqq " seems to be not reachable anymore....
Where could I find a binary image to flash for my P760?
Do you want me to describe the error I got in a post on that thread? Of course I'll do if that is more correct in your opinion.
TY very much in advance!

Hi Rosso Corsa, you're welcome.
The download link works fine for me.
Try again from your computer or with another browser (i. e. dolphin).

I tried do get to this address:

And also to this one (after having seen the image you posted in your last append:

but in both the cases I got a "Unable to connect" message.
I tried from my laptop with Firefox, Internet Explorer and Chrome, getting always the same result.
Do you know what I could try to get this bin image?
On alternative, do you know any other address where I could find a bin image for my LG P760?
It seems the tool for getting a bin image from kdz is not running correctly. At least I got the same error messages others indicated....

Hi Rosso Corsa, you're welcome.
I don't have any other link.
You could try without your firewall or antivirus or with another PC (friends, family,neighbours,...).
Eventually you'll got it!

The Problem:
Phone stuck on LG logo screen with "Security Error" written underneath.
How I Got Here:
Rooted and installed recovery using apks found in these forums. I successfully restored a CWM backup zip found on these forums. Next, I decided to try flashing a ROM. SuperLuminal gave me a "Status 7" error, but when I checked over the thread, I realized that the P769 was not specifically mentioned as a compatible device. So, I decided to give PACman ROM a try, but got the same error.
I googled "status 7 error" and found a guide for fixing this (removing "assert" line in updater-script line). I was aware of the danger in doing this, but since PACman ROM stated "P769" right there in the title, I gave it a shot. Now I'm stuck with the "security error" screen.
What I tried:
I could no longer get into recovery, so I thought restoring it might be a good idea. I tried to use fastboot using the method described in this thread (http://forum.xda-developers.com/showthread.php?t=2310569). However, I quickly realized that I didn't know how to put the phone into a "download mode" like most other phones I've worked with.
I then tried B2CAPP, but phone couldn't be detected. Went and learned how to get into s/w upgrade mode, ran recovery and got an error message saying "updating is not possible any longer due to a fatal error..."
Next, I tried uninstalling all LG software and rebooting PC. Installed LG PC Suite found here (http://en.kioskea.net/download/download-19186-lg-pc-suite), allowed the program to update to latest version. Then tried to run Emergency Firmware Recovery, which opened a window asking if I want to run LG Mobile Support Tool. I clicked OK and was taken to an app that looked exactly like B2CAPP and gave me the same error as above.
So in conclusion, I can only access two screens: the LG logo security error screen and the s/w upgrade screen. Neither appears to give me access to fastboot/adb nor to LG's recovery tools. Am I permanently bricked or is there a way out of this mess? I've been searching these forums extensively and have tried every method I could find. I'm out of options, so I'm kinda freakin out here. Can anyone please help me figure out what else to try?
You did some studying for sure, but you needed to do some more before jumping in.

Kuma82, I can't thank you enough for your helpful response.
Here's a shortened version of what I did, in case someone out there finds themselves in a tough spot like I was in:
1. Installed OMAP drivers using method described in link above (right-click on device in Device Manager, manually install driver, etc.). Fastboot worked after this
2. Using Lelus' Fastboot, flashed option 6 (load JB xloader and uboot). This gave me an inverted purple LG logo that still said "security error"
3. I think tried to use fastboot to flash the p4_769.img recovery file. No change. Loading up s/w upgrade mode and the LG Mobile support tool (B2CAPP) was no use (stuck at 15%, no connection to phone).
4. Once again, using one of the links above, I downloaded 3 .img files and proceeded to erase uboot, boot and recovery and flashed those .img files instead. When I rebooted the phone, I got the regular LG logo for a second, then a white flash and then a smaller LG logo with "security error"
5. Now, I installed the LG United mobile driver, went into s/w upgrade mode again and ran the Mobile tool. Got the "updating is not possible..." error again
6. Searched for the offline flash fix method and followed it step-by-step, word-for-word. Phone works again!
I'm pretty sure I could have just done steps 1, 4 and 6 and achieved the same result.
Hope this helps someone, and thanks again Kuma82!
I've had this happen to me twice and was able to get out of it really easily. Basically, I just have my desktop set up for offline flashing and my laptop for online. Just popped into S/W update mode and plugged it into the laptop, started the b2c app, clicked on the "recovery phone" option, and went for a snack. Fixed when I came back.
No problem, glad I could help.
Now that you know how to use fastboot, you are pretty much ready for everything.
It took me a couple of tries to get it running.
Use the new root method, http://forum.xda-developers.com/showthread.php?t=2338816
If you plan on staying on stock, get the cwm for locked bootloader, but first get this busy box http://forum.xda-developers.com/showpost.php?p=43395803&postcount=260

Dear, Kuma82!
Thank you very much fot your instruction! It really saves my LGP768 from "security error"! I follow 3 steps and it works, GREAT!
Thank you again and this forum too!
Please help! Bricked LGMS769 (P769)
Solved. The LGMobile Support Tool needed to run on a different computer. It worked when I put the phone into SW Update Mode (press up volume key and plug in USB) and then ran the LGMobile Support Tool.
By the way, this is how I got the phone recovered after it was booting to the small LG logo with the "security error" message as mentioned in Step 4 above.
Hello guys,
Ive been lurking here for a while and i finally thought about joining the gang.
I cant find the LG E510 thread here so please move my thread if this place is inappropriate. Thank you.
I updated this E510 via the LG mobile support software and the install [after downloading firmware] got stuck at around 4% then at 14%
The software prompted me to remove the phone from connection, pull out the battery then try again. Now its stuck at boot screen.
I can start up the "Emergency Mode", where its the only way my PC can recognize the device connected. I tried using the LG software again but i get this:
Hard reset is said to be VolDown + Home + Power On yet it doesnt work, only gets to logo.
This is an unrooted phone that why i used LG-provided update software.
THe PC can detect the devices and installed drivers. The software can too, but this error is persistent.
A friend said something about disabling the LG modem in the device manager but i still get this error.
I have ADB which i used sometime ago with my HTC but the ADB says device not found.
Any help would be appreciated.
Thank you very much.
*** SOLVED
I dont know what exactly made it work but i did the following.
Disabled [not uninstall] all other devices installed by the phone except the LG Android Platform
- disable and restart. if uninstall is used windows will just install it again after restart. disable.
- may be a problem with my PC that it has difficulties connecting with the phone if the other child devices are on
Uninstalled the Update Software and Installed it again
This time i clicked Options > Update Recovery
- prompted for my Phone Model + SN or just the IMEI <- brainfart on my part shouldve seen this earlier
The software downloaded the exact same firmware V10H_00.kdz and installed it. Success!
Maybe there was something bad with the first one i downloaded being on WiMax connectivity.
I feel so stupid right now being unobservant and all...
Anyway thank you!
Hello guys.
I've been trying to do this on my LG Optimus L5 II E451g and it doesn't work. I can do the NORMAL FLASH but it didn't fix my problem so I want to do the CSE FLASH (to do a clean install). But I can't do that one.
Everything goes fine until the third step: "Wait until software extraction is complete..." then after a few seconds it crashes "LGUserCSTool LG Mobile has stopped working".
I'm using Windows 7 Ultimate SP1.
I tried different drivers, the old method with the host file automated (says the phone is not connected but it is), LG Update Tool 2014 and KDZ Update but nothing works. This error says the module with trouble is "msvcr100.dll". KDZ file is in the software folder, Windows recognizes the phone when I conect it to enter Download Mode, I installed every Visual C++ package I found, everything seems fine but it doesn't perform the CSE FLASH. It does the NORMAL FLASH so the KDZ is fine.
I'm sick of this. I don't want to buy a new phone. Anybody has any idea???
Regards.
I have EXACTLY the same problem here.
And I can't flash KDZ to at least recover the phone. System got corrupted, so it doesn't boot. Recover doesn't work (just shows the open robot with the exclamation sign). Download Mode works but the tool throws this error.
Hi everyone!
I recently bought a LG V10 h961n from eBay. I had no interest in root, so I updated it to marshmallow. However, I encountered huge wi-fi connectivity problems: the phone would connect to WiFi, but only really close to the router, and the latency was unexplainable high. The only workaround I have have found was a guide posted here in XDA which required root.
So, I started digging and I found a tot file of lollipop already rooted. I downloaded the kdz for lollipop hoping to downgrade using lgup and/or flash tool. All the flashing end with a 0x2000 error code in lgup and a "contact your system administrator" error on flash tool.
Now,the phone is stuck into download mode whatever button I press: power to boot normally, power+volume down or up.
The only combination working differently is volume up+down+power that bring me to the IMEI.
In the end, i was hoping that someone was able to find a solution. I really love this phone, and I would really feel bad if I had to throw it away and buy another one.
Thank you in advance.

Solved, just kept trying to connect to lg bridge. In the end it detected my phone and installed the os by clicking on "update error recovery". Hope you'll solve too!
Referring to this thread https://forum.xda-developers.com/lg-g2/general/mega-tut-how-to-fix-bricked-lg-g2-t3055033
I have found a shorter method of unbricking your LG G2 after troubleshooting uppermentioned method for quite some time with no result.
Your phone is stuck at boot in Dload>Download-Mode>Fastboot, mine is LG G2 D802
Your phone will not do Hard Reset when entering recovery and selecting Yes
Windows 10:
- First Install LG G2 Driver. v4.x works fine, I tried many and didn't have any problems in that regard, drivers all work fine
- Download LG Flash Tool 2014, not the fancy new one, but this old version
- Find the most accurate backup .KDZ file of your phone's OS, mine is EU16GB, and the file that worked for me was D80230d_00.kdz. Flashing the wrong rom will result in bootlooping that can be fixed by restarting the process.
1) USB connect your LG G2 in Dload/Fastboot to your PC
2) Run LG Flash Tool 2014 with DEFAULT SETTINGS, press select KDZ file, find the KDZ OEM ROM you found online that matches your phone perfectly, select Normal Flash and click Start
3) Your phone reboots into Firmware Update
Firmware update is the flashing process happening
If it fails you can try again by restarting your phone, or try another KDZ ROM
4) Once the flashing is done the phone restarts itself and boots into the OEM OS
5*) if unsuccessful try a different .kdz, personally I had to try three of them ,_,
i pulled these steps from my memory, i try updating if something is wrong
If I may ask, what do you mean with "1) USB connect your LG G2 in Dload/Fastboot to your PC"?
Could yoiu please elaborate what "in Dload/Fastboot to your PC" means?
