My lg logo g2 fails, you fall caught. The case is that I haven ´t download mode, I have the official lg recovery but when I do it gets caught when factoring reset. Previously I followed the tutorial for linux, but in the last step of recovery I installed the official TWRP instead of lg. The case now my phone will not start, as I said earlier stays at lg logo and neither recognizes windows. Before the error came out and particiciones qusb_load driver or something. In linux not recognized and therefore can not repeat the steps to install the TWRP recovery
Please have to see a solution, I can not believe that it is irreversible, you need to see a way to start the mobile.
I'm not the only one to whom this has happened, there are more people like me, I'd be really grateful if someone could help because this is frustrating and I had never been anything like
thanks in advance.
Hi dude,
Seems you are stuck in boot loop mode.
Get a KDZ file for your phone and follow instructions in here

I have posted in that link and follow my tips if running win xp.
Good luck and don't give up. It's easily recoverable.

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

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.

Sent from my LG P76020L-EUR-XX unlocked and rooted
I recently received both my Nexus 5 and LG G4 second hand boot-lopped and I, with prior experience, hopped to restore them. I downloaded all the images and firmware needed and tried to get the most recent versions to avoid any downgrade problems. Then everything went south. Using the lg tool, the G4 got flashed 100% but then that was it. It would not boot up and not turn on. My computer would recognize it but it would leave me a "Unknown USB Device (Device Descriptor Request Failed)" message. At that point I lost hope and moved onto the nexus 5. I used wugfresh nexus root toolkit and went through the usual process of unlocking boot loader and downloading image. Well when it started to flash boot.img it restarted and that was it as well. Now both my nexus 5 and lg 4 are dead and leave me the same message when plugged in. I'm very confused as to what has happened. I've done this dozens of times before and it has never given me this. I believe they are hard bricked now and i dont know why. Is it Windows 10 anniversary update? Is there a solution? I'm desperate and lost at this point because I cant find anything online. (Not able to access recover mode on either). Please help.
Check this out, there are a couple of videos too. Also, how did you flash your nexus 5 image, did you use adb or fastboot? As for the LG phone, take a look at this thread, it might be a hardware issue that is LG's fault.

Thanks I'll look into it. As for the Nexus 5, it was done through adb. The thing I'm not understanding is why it happened. Usually my nexus devices don't get bricked like this and it weird that it happened to both of them

I recommend flashing via fastboot instead (fastboot flash boot.IMG) But you'll have to look into the link to solve the driver issue.
Hello, I have a bricked Virgin Mobile LG LS665; here's how it happened
The LG LS665 recently got an OTA update. However, my phone was rooted, so I could not apply the update. The patch was failing because some of the system partition files had been modified. I found out that the original versions of the modified files had been backed up by the tool I used to root my phone, and thinking myself clever, I restored the original files, and applied the patch. Of course, this didn't work, and my phone got stuck at the LG logo whenever it tried to boot.
When I tried to boot it into recovery, it would give the error "Secure Boot Error 1006" and reboot to the LG logo. From what I gather, this boot error comes from the bootloader not recognizing the boot image. Dang. Not one to give up, I searched for unbrick solutions for the LG LS665, and found some. Unfortunately, the only methods I could find were for the Boost Mobile version of the phone. Reckless as I am, I decided to try the Boost Mobile unbrick process, but only managed to brick by phone harder. As a new member, I can't post a link to the unbrick process, but it involved flashing a .tot system image with LGFlashTool. I may be wrong, but my research leads me to believe the process failed because the partition tables for the Boost Mobile version and Virgin Mobile version of the phone are different.
Now my phone will not display any boot screen; I can't get it into normal, recovery, or download mode. When plugged into my computer, Windows device manager lists the phone as "Qualcomm HS-USB QDLoader 9008". Googling that device name brings up a few tutorials of how to revive devices in this dire state, but none that seem to work without a correct system image. I believe it is possible to unbrick my poor phone, but I am not knowledgeable enough to figure it out on my own. If anyone with a clue what to do is willing to help me, I would be very grateful.
In summary, what I think I need:
Some sort of system image for the Virgin Mobile version of the LS665. (I think a .tot or .kdz file)
A kind, knowledgeable soul to point me in the right direction
Thank you for hearing my lengthy plea,
Grant Moyer
