Hi everyone, I'm new here, please be kind with a noob like me if it's simple the resolution of my conflict with this lg.
Let's talk about the phone, it was having a security error, but can get into S/W upgrade and into fastboot (but after a couple minutes disconnects i don't know why)
Well, i tried with lg mobile tool downloading the firmware and trying to install it, but always gave me a error communication between cellphone and pc at 50%.
So i tried to download the kdz using the imei from http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=MYIMEI
i tried with kdz updater, kdz updater offline, with all guides here and same error at 50%
then with nothing to lose (at least that was i thought) i followed this guide http://forum.xda-developers.com/showthread.php?t=2585161
and, after delete boot, uboot and recovery and installed those .img my 768 doesnt do ANYTHING.
Just i can ran the phone into fastboot, i don't know how to resolve this, i tried with lelus fastboot and omap4boot, both install sucessfully x-loader and u-boot, but the cellphone still doesn't boot into S/W upgrade or gives me security error, doesn't do anything, if anyone can help me with this it would be appreciated..
Sorry for my english, greetings from Venezuela.

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
Then this cwm

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.
Hey all,
So I successfully rooted my phone, and then I was going to go into recovery reboot mode to install a downloaded rom. I'm not sure what did it, but on that restart I got LG Security error. I first attempted on three different computers to do LG Mobile Support Tool. It stopped everytime when it was going to begin downloading the files. I'm pretty sure if I still had the Security Error image, I would be fine, because I now know of ways to bypass the LG Support Tool, and edit the host file, and then get it downloading.
Either way, in my research after no success with LG Mobile Support Tool, I came across Fastboot. So I got fastboot, I got the drivers installed, but I'm pretty sure my problem was, on the command prompt screen when Fastboot asks' you questions I said yes on them. I believe this is what caused my phone to have the black screen. It will not go into S/W upgrade mode now. It will not do anything, just black screen. I found a tutorial over on Android Forums, and with using Fastboot, I was able to sucessfully flash "p4_769.img" According to that tutorial, after doing that I should have a dead android guy logo, and then just be able to hard reset... but that didn't change anything. Still have the black screen. Still won't go into S/W Upgrade mode.
Now according to what I've read, the next step would be to flash KDZ Afresh...I've looked for this, whatever it is, specific to my model phone, but I can't find anything. If anyone else has any ideas, I would love to hear. I'm so frustrated at this point. Very much appreciate any help. Thank you.
It sounds like now what I have to do is, using how I flashed that recovery img, I first should flash the x and uboot.bin files to my phone. Then I will be able to get into S/W mode, and then restore from there. I just have to find these bin files. I don't have a friend or anyone nearby with the same phone as mine that can:
adb shell su -c busybox dd if=/dev/block/mmcblk0p2 of=/sdcard/external_sd/p2.bin
with theres.

sorry dude but your phone is hard bricked your going to have to buy a new device.
Hello guys! I have a problem with one phone that i am trying to fix for someone and I feel sooo, sooo completely lost in all of this as I know almost nothing about this. The cell phone model that is in question is Alcatel One Touch Pop C3-4033x.
It seems to be using a Mediatek chipset and I was reading some of your advices here & there and tried using the program called SP FlashTools but it always resulted in error, in the end. It seems that something is wrong with this phones emmc flash memory. So, I tried transfering some files as a zip files to the SD-card and tried to apply update from it, but it said always: Installation aborted. And then, I have tried looking for a way to flash stock firmware of that specific Alcatel model on SD-card, but I just don't have any clue how to do it, if it is possible, even. Maybe I should just give up trying?
Oh, I almost forgot to write that the phone doesn't have the access to Android OS and USB debugging isn't turned on, because computer doesn't seem to list it and I don't know if there any button combinations that Alcatel uses for this model to get into that fastboot or adb mode, even though have installed mediatek drivers. It can only get into Android System Recovery 3e. That seems to be everything, I think, at least.
Oh guys, I am so, so, so sorry if I am bothering you with this. I just didn't know what or where else to ask this. Thank you sooo much!
Hi download those files:
Firmware:
https://www.mediafire.com/file/bpm4ibsbmr4q6nc/OT-4033X-Without_Mobilis_logo__BY_GSMSERVE.rar/file
SP Flash tool:
https://androidfilehost.com/?fid=11410963190603870440
Driver:
https://mega.nz/#!8VYkQCxD!fkhTrZwFFILDAglO1cR_8pIM4Cel52brZ7RB6QZoc6o
Once you downloaded all right driver open SP flash tool and add Scatter file
MT6572_Android_scatter.txt
Click on Download , connect your phone without battery and see if the process is going on if not try again with battery inside.
If you end up with error do the same thing but now first do Format then after is Finish do Download. Good luck ...
It still displays error :/

I have tried to do everything like you have said, but it still displays error when i press the Download button, and it displays that error after some seconds pass and also the same happens hen i try to use the Format function. This is the error it displays when i tried with the download button: BROM ERROR: S_DA_SDMMC_WRITE_FAILED (3149)
And this is the same error it displayed when i tried using the Format function: S_DA_SDMMC_WRITE_FAILED (3149)

Hi everyone,
After an error occurred during ROM installation, my 998 was stuck at the boot screen.
My phone can still access TWRP and download mode so I tried KDZ but currently LGUP does not recognize the phone.
I have tried many different versions of LGUP and I am sure I installed it correctly but there is still no way to access LGUP.
So can anyone show me a solution?
Thank you for reading. And sorry for my bad English
