Hello,
I was recently trying to load a stock rom on my LG540 and the process was interrupted because of a power failure. But the phone luckily booted into "download mode". I want to reflash using the procedures discussed in various posts on bricked phones, but my computer can no longer recognize the phone. The KDZ updater reports "Phone not Found". The correct drivers are installed and I am running windows 7 home edition.
Any thoughts as to how to get the computer recognize the phone?
Thanks, MN
maybe using "Run as administrator"
Try installing these drivers, they helped me when I first used KDZ. The links are from a hungarian site.

I think the bootloader is corrupted, it's basically "bricked", but not fully
Drivers must be the issue. Try uninstalling LG driver, reinstall it or use Windows Update to install drivers.

Maybe you can use LGDP2 ??

Hi, looking for some help with a soft-bricked SGS i9000.
It is bricked to the point that it only shows the 'Phone--!--Computer' when switched on, or when attempting to access Recovery Mode.
I can access Download mode absolutely fine, but Windows refuses to recognise the device when it is plugged in, therefore it doesn't show up in Odin, therefore I can't flash a new ROM.
Is there anything I can try to get Windows/Odin recognising it?
(Someone on another thread suggested just unplugging and replugging the phone until Windows recognises it - should I give this a try?)
Thanks.
I assume you have tried reinstalling the drivers?
Yeah, I've removed the device from device manager, reinstalled the drivers and re-plugged it.
Then I've tried updating the drivers via Device Manager - the message I get is that the best drivers are already installed.

Uninstall whatever drivers you have installed at the moment and read this thread:
http://forum.xda-developers.com/sho...an always uninstall and install Samsung Kies.
try a different usb port, sometimes you can actually fool windows with that, i have had the same a couple of times, rebooting your pc or using a other pc sometimes works...
can you enter to download mode? It should be recognised by odin. If not you need an usb jig.
I had the same thing, so i looked around and someonle suggested installinog nexus S drivers and Odin recognizes your phone!!
It really works.

Hello,
After I've failed to find solution, I've decided to make a new thread. My phone is bricked, meaning that I'm stuck on Avatar ROM. When I try to use CWM manager, it requires me to install recovery mode, which was somehow deleted. Problem is, neither mobile connection nor wifi are working.
And I can't access recovery mode by holding buttons neither.
When I got in trouble before, I used Smartflash tool to flash the original rom. This time my laptop doest recognize phone connected through USB any time. After trying to find a solution for 2 weeks I gave up and asked you guys for help.
I have tried everything: Drivers, N/W upgrade, etc... my laptop just doesnt react when I plug in USB at all.
I almost went crazy after trying every possible driver and still nothing. Once after installing drivers and connecting phone withouth battery in N/W mode, it looked like windows recognized phone but then it said "device unpluged", and since then I cant even get this message again.
Please help! Thanks!
did you try All-In-One Toolkit ...( http://forum.xda-developers.com/showthread.php?t=2020737 ) first go on step 4 ( but you must have some rom on your ext sd card ) and of courese apx drivers installed on your pc
the O2X cannot be bricked! Try AIO Toolkit

I've heard about this, I treid it as well. But my main problem is USB connection between PC and phone. I have win7 64bit. Are there any other drivers I should install besides the oficiall LG driver ?
You need apx driver to nvflash, but aio leaves full instructions along the process of both nvflash and smartflash. Ohh, USB 2 are preferable so maybe you need another computer and never use hubs....
Rooted LG D405n, nothing done to the software beyond that (unless you count having zooper/nova launcher configured on it). Gave the phone to a friend for a short while and she decided to update the software using the LG software update on the phone. After she selected install on the latest update which came out not long ago and was supposedly going to update the apps, it restarted and got stuck on boot screen with Boot Ceritification Error [560].
I've tried this guide http://forum.xda-developers.com/lg-l90/general/guide-flash-stock-kdz-offline-lg-l90-t2803479 but I got stuck on step 4. because I cannot make the PC recognize the device (it does not show up at all), so the LG tool can't install USB drivers. If i try to do it manually (it gives me an option to select a device from a list) it doesn't seem to do anything, just gets stuck on the Downloading USB driver window.
I can put the phone in Firmware Upgrade Mode just fine, but it doesn't seem to do anything useful. The PC still won't recognize the device, however I can hear the 'usb pluged in' sound (I'm on Win7).
Did a factory reset, didn't help.

You could try the LG Support Tool. Not sure it will work but it's worth a shot. The problem with the phone not getting detected by the PC is the fact that 1) The OS was upgraded by your friend and 2) The factory reset you performed . Both of those acts would have disabled USB debugging hence no device detected.
I unfortunately have no encouraging information to give you.

It appears that I have fixed it.
Since The tool would not download the USB drivers by itself I went to the LG website and got them manually, installed them and restarted the PC.
After that I launched the LG Mobile Support Tool, but it still didn't see the device.
However, I clicked Options and Upgrade Recovery. It asked me for my IMEI. I put the phone into Firmware Upgrade mode and the program started upgrading the phone.
After it was all done, the phone restarted, and the software update simply said that instalation failed, I have lost root but everything else seems fine. Rooted again with towelroot and I'm back in game.

Well I'm glad you managed to fix it.
Since this issue appears to be solved, please insert '[SOLVED]', without the quotes, at the beginning of your thread title.
Hello everyone!
So I've been doing a lot of OS tests on my 2x, but this time I think i screwed it up.
The situation is the following: The phone only boots until the lg logo (have ICS bootloader) and can't boot on recovery (don't think he has recovery right now).
So it is completely empty besides the bootloader. Furthermore I don't have the proper drivers installed on my computer. When I turn the phone on and the windows trys to install it fails.
UPDATE: I've been able to boot it on S/W Upgrade to the computer and the windows installed the right drivers - I will try to smartflash a ROM
So I need to fix this situation...
What have I done:
I've downloaded the drivers from LG and LGMobile Support Tool - this last one cant recognize the phone in the current state.
I've downloaded AIO and installed NVFlash Recovery in order get the new Partition and unlocked bootloader (It's currently unlocked already) and put a new recovery image but i always get "USB device not found". I know this is because the drivers aren't there. But how can I install the drivers of the phone itself if I can't boot it up? (Note: I've already installed the lg drivers).
So... What exactly can I do?
Thank you for any help provided
If u can boot in s/w so u can smartflash a stock rom, or install apx drivers there are in aio somewhere it should work and next flash recovery 5.x.x.x so u can repair emmc for flashing roms copy zip to your phone and flash
This kinda worked.
So I tried the smartflash the baseband and ROM. But i got an error and the process was incomplete although i think it did installed at least the bb. After the error, windows started installing some nvidia drivers and I thought that the computer had recognized the phone. And so after that I've tried to change my recovery image and it worked well. The PC could connect through nvflash.
It is now fully operational!
Thank you very much
No problem bro )
So I think I may have bricked my phone unless I can get the H811 20i KDZ file but even that may not be good enough to save it. I'll start with where I am currently at. On boot I get the error:
Secure booting error!
Error code: 1003
Modified
I am able to get into download mode by pressing the up volume key or into the wipe mode by pressing the down volume key. However, no matter what I try I can't seem to get it to reboot normally.
Here is what I did to get myself into this situation:
I stepped through the guide to install MM and then I performed the fastboot OEM unlock and booted into TWRP. I then installed SuperSU and rebooted. Then for reasons unknown I decided I would relock the boot loader and so I ran the command fastboot oem lock. I fully understand the stupidity of that thought now but didn't think very clearly at the time.
Here is what I have tried:
Using the LG Support Tool I attempted an Upgrade Recovery which failed.
Using the guide on here to return to stock I attempted the method using the kdz file for h811 10n but that fails at the upgrading your phone with the error message "Upgrade stopped due to an error". I have attempted the retry button numerous times without any change in responses.
At this point in time I am game to try anything.
:fingers-crossed:
Thanks to autoprime I am now downloading the kdz for MM and when it is complete I will attempt to use LGUP to restore it.
Well I get an error message from LGUP stating that I don't have the correct DLL for H81120i installed. I attempted to replace the dll with the one inside the MM kdz but that didn't work.

Oh I wish it were that simple. I had tried it last night but attempted it again as I couldn't remember what happened. I get an error message stating "Connect your mobile device to the USB port. If it is already connected, contact LG customer service."
At this point I think I may just need the MM dll to use with LGUP. I attempted to use an MSI packaging utility to replace the dll in the 0.0.3.23 installer with the dll I extracted from the kdz file but that got me nowhere.
I attempted to use the LG FlashTool v1.8 and found out that the dll that I extracted is ver 0.0.3.21 which is older than the msi version found on here. Does anyone know how to get a newer one?

I had the same error and sucessfully used lgbridge. You probably need to reinstall your usb drivers.
OK I'll give that a shot.
No go...
I uninstalled anything I could find related to LG. I then reinstalled the LG Bridge software which then updated the USB drivers to 4.0.4. I then rebooted my computer and attempted it again and I got nothing but the same error.

I had this exact same issue when upgrading my phone. Didn't do it correctly and it took me about 3 hours before I got my phone working again. It was about a week ago on another computer, but I'll try to recall what I did when it finally clicked in my mind.
Download H81120i_00_0201.kdz flashable zip from here (1.6GB Feb-04-16):
http://downloads.codefi.re/autoprime/LG/LG_G4/H811/H81120i/
Download LGUP and install it. I used the DropBox link in this thread:
http://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
Remember to install the LGUP_8994_DLL file BEFORE LGUP_Install
Download and install LG Bridge (for the USB drivers) here:
http://www.lg.com/uk/support/pc-suite
Select the LG 815 model, the drivers will work. I only used the LG Bridge to install the USB drivers. Nothing else.
OK, now here's where your phone comes in.
Step 1: Turn off your phone (pull the battery if you must, but put it back in).
Step 2: Hold the VOLUME UP button and plug the USB cable into your PC. This puts your phone into DOWNLOAD MODE.
Step 3: On your PC, open up LGUP. The program shoud recognize the phone as H811 in COM3 or COM4. Highlight it and click the SELECT button.
Step 4: Under the "Process" row, select UPGRADE
Step 5: Click the blank space under File Path, it will pop up a [...] [X] at the end. Click the [...].
Step 6: Select the H81120i_00_0201.kdz and click on Start. The program will push the STOCK H811 MM ROM to your phone. This will bring your phone out of Brick mode, but you will have to go through the entire rooting process again.

Woohoo!!!!!!!!!!!!!! I changed two things and I'm not certain which one it was that finally made it work but I followed your steps and installed the LGUP_DLL before the application (upon re-reading the original thread for the LGUP program I see that is the way you were supposed to do it the whole time, so much for reading comprehension) and the other was I ran it from a Win 7 VM instead of Win 10.
Big thanks to you and also to bender_007 for walking me through a bunch of stuff and recommending the VM approach.
I did the exact same thing, but I cannot get LGUP to recognize my device. Uninstalled and reinstalled drivers and all. Any other ideas?
I did the following:
Installed Windows 7 in a VM
Installed the LG Bridge software and ran in do it should update
Installed the LGUP DLL
Installed the LGUP software
Connected phone to VM
Then ran LGUP tool

What does the phone show up in Device Manager as when it is in download manager? Mine is showing as LGE Androidnet USB Serial Port. Is this the same for you?
hv same problem. but problem is pc can't recognize the phone for below step:
Step 3: On your PC, open up LGUP. The program shoud recognize the phone as H811 in COM3 or COM4. Highlight it and click the SELECT button.

same... I think it might have to do with the from that was installed when I relocked the boorloader. I'm so stupid for that.
I was trying different drivers, but none have helped lgup to recognize my phone.

first of all, how can we make PC detect our G4?
actually, even w/o any drive installed in PC, the PC should detect G4 if it works normally.
Device Manager shows my device, but as "LGE AndroidNet USB Serial Port". From what I have read this may be it's bricked mode. Is there anyone with an idea on how to come back from this?

Can't use Send_command too.
MM relocked the boorloader was stupid.
I had this exact error yesterday. I used cdmatool to get some bands enabled so I could get AT&T LTE with an AT&T sim and T-Mobile phone. All went well, and on my way out I figured since I had done the fastboot oem unlock, I should probably relock it. BAD IDEA.
By the time I found this article I had figured that somehow I needed to reflash to a ROM with a unmodified bootloader. This article is great! Such a rare treasure - all of the links to the necessary software and a short-but-sweet guide all in one. This post saved me hours, maybe days, of searching and trial-and-error.
By the way, since I had already installed the LG device drivers (available here) it was not necessary to download and install the whole LG Bridge.
THANKS!
Many times tried to flash my H811 to 20i but always ended with blank screen...is it have to wait until 5 to 10 minutes to get the phone rebooted after flashing with LGUP? Because usually ended with blank screen and qd mode, have to revive using qfil, imei unknown, camera and google play store always closes.
