I have an LG K7 on Metro. It's in some sort of boot loop. I have searched XDA and the net for a solution and keep coming up with solutions involving download mode. I'm unsure of what to do next. The phone has Error # 9 Authentication error as well as error 1009. When trying to go into Download mode it goes for about 10 seconds and then reverts to the LG welcome screen. When you try to turn it on it just stays on the LG welcome screen or cuts off. When plugging it up to my Windows 10 PC it shows LGE Android MTP Device in the Device Manager. I've tried to download the Drivers from the LG site and ran the installation on the computer with no change. I've tried to update the drivers from the Device Manager Screen with no change. It also gives you the noise when it connects to the PC. LG UP won't recognize the device and neither with the LG support tool. I have tried everything that I am capable of understanding at this point (which isn't much). I have read about trying to get it into EDL but can not find the correct test points... even if I did find the correct test points I'm not sure if that will even help me to fix the device. I need to breathe some life back into this phone. I hope I did not post this in the wrong place, or violate an XDA rule. I just really need some help... XDA has the most complete guides and accurate information I just can't find it about my particular situation. Anyone's assistance or thoughts (written to a non-techy person/non-developer newbie chic) would be helpful. This is week 3 of me scouring the net for answers. Thank you

Hello
Yesterday I was flashing my ROM but it failed. Now when I try to startup the phone (LG D802) it doesn't even give me the LG startup screen. I did some research and tried to start with an NVFlash. I'm kind of new at the smartphone world, they are telling me to take out the battery but is it suposed to be this hard to take it out? Screwing it all lose, disconnecting a lot of connectors?
So I started without taking the battery out, in the device manager I do not get an APX device but the QHSUSB_BULK, when I try to install the driver to this device it says the folder does not contain any driver...
That's how far I get, I tried to find some similar threads right here but anyone else seems to manage to get into some fastboot mode or download mode or something similar. I don't...
Any help is welcome...
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!
Ciao
Mauro
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).
Cheers. Good luck.

BajoPrimate, ty for your support.
I tried do get to this address:
uploaded.net/f/xh3dqq
And also to this one (after having seen the image you posted in your last append:
uploaded.net/file/j32p8p7y/from/xh3dqq
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....
TY very much!

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!
Cheers. Good luck.
I have a bricked LG E455F, it is stuck in a boot loop with recovery mode inaccessible due to a "Security Error" message, leaving me with the option of flashing it.
At first I would like to say I'm new to this kind of procedure, if anyone knows any other fix, it would also be very appreciated. In a first moment I tried using the LG Mobile Support Tool, however, every time it gets to 5% it shows me this error(not allowed to post images yet, so here's the imgur image path "/ssZCcSl.png"), as in each try it would download everything again, taking a really long time, I started using the LG Flash Tool 2014, again, with no success, I tried changing the COM ports, removing battery, changing usb port, even using a different computer, searching for this problem I found several other people at the same situation, however, almost none solutions, and zero working solutions.
I would like to, if possible, try at maximum to keep the files I have in it and keep as stock as possible. So, what would be the best course of action in this case, how should I proceed?
Obs: I am using W10, and my second computer W8.1;
Obs²: The ROM I'm using with the LG Flash Tool is the one downloaded by the LG MST, I just copied it before it was automatically deleted.
Obs³: I can still access Download Mode.
Same problem here
Im facing the same problem here,
I had something similar happening to a d605, flashing would not succeed and I tried A LOT of different things, even dismantling it to short a resistor and make it boot in mtek mode to flash via SP flash tool, SP flash tool reported it could not find the EMMC of the device.
I then googled about it and found out a LGs phones are having EMMC problems once they get 2 years old. So I guess its just a matter of LG making ****ty phones that do not even last more than 2 years.
Im afraid this device is having the same problems...
when it reaches 5% remove the USB cable and connect again
I have done so much and probably have everything I need downloaded already but I am stuck.
LG - K 7 - Family Mobile (Wal-Mart/T-Mobile) phone
Tried to root it and got stuck into a security loop and was able to get into download mode at that point, I used LGUP and now my phone will not do anything. I can not get my computer to recognize it, it does nothing when plugged into charger. Its like stuck off so I cant get to a download screen flash my phone back to the way it was. Please I need help, ive found all the links to people in similiar situations as me and none of them have unlocked this BLACKOUT BRICKED UNLOCK ABLE MODE!
Different programs from android studios to LGUP to ADB and Fastboot, LG support tool, LG Flash Tool, and all the necessary files like LGUP_Lab_Frame_Ver_1_10, LGUP_K330, LGK330.dz, The K33011e (Walmart Family Mobile) zip file, proper .kdz files and some others.
PLEASE HELP ME.
Would be forever in your debt

sorry dude but your phone is hard bricked your going to have to buy a new device.
I have a LG K7 MS330 whose software was not working properly. Looking for a solution, I found that there were several firmware updates of this terminal (I had the version 10e compilation), which basically consisted of more recent versions of compilation distributed in kdz files. I proposed to download the latest update available ensuring I download the file corresponding to the smartphone region (MTP in my case).
So, I downloaded the file MS33010k_00_0405.kdz, the tool LGUP 1.14.3 and the file LGUP_MS330.dll version 0.1.2.7. I connected the phone to the PC and started the process.
At 99% the installation failed. However, I could still enter in download mode. So, I download an older version, the MS33010h_00_1021.kdz and repeated the process. This time I got no error.
However, when I finished, my phone went into hardbrick mode. Check the battery and no problem, even charging perfect inside the phone. I do not think the device has any problem with hardware as it worked before. The only life signal I have now from the device is connecting it via USB to PC and press the VOL +, VOL- and POWER buttons simultaneously. In this way, Windows recognizes it as "unknown usb device".
I would be grateful to anyone who can help me with this problem. Regards
I have the same problem!! Please!!
