Check if you have the latest drivers, connect the phone in recovery (vol- and connect to PC), flash with LGFlash Tool.

There is no other way...
Did you follow the tutorial? Did you remained calm and gave time for windows recognise your device?
Did you uninstall and re-install the drivers? You're able to reboot in SW mode (vol- pressed while connecting to PC)?
Here you have all files needed:
http://forum.xda-developers.com/showpost.php?p=38838927&postcount=7
Delete your old files, download new ones and follow the tutorial.
Remember to remain calm and give time to system recognise and install everything needed.
Good luck :fingers-crossed:

TNQ...I fix my LG...and know work perfect I put 20A kdz. 4.1.2. and phone work perfect
Same problem here
I have the same problem. I think the stupid thing I did was to install V20a without rooting the phone. Now I cant root it. IS11LG_SystemBackupTest.signed.ap would not run and when I try to recover either with LGflashboot or LG firmware recovery I get the same error message "morning call is empty" (very strange error message). I can go back to v20a but since I am not completely happy with it I would like to resolve it. Is there any chance to fix it? I am not very confident to format bootload or installing custom ROM.
Thanks

You cannot root the phone on V20a using IS11LG_SystemBackupTest.signed.apk, since that file is used for versions V10x. Check out this link for rooting V20a: http://forum.xda-developers.com/showthread.php?t=2180688

Uninstall all drivers and folders like "LG United Mobile Driver" and "LG USB Modem Driver".
Re-install the drivers:
http://www.4shared.com/file/rPpP2btT/LGUnitedMobileDriver_S4981MAN3.html
http://www.4shared.com/file/ZSMf2x6n/LGUSBModemDriver_Eng_WHQL_Ver_.html
Take out the battery, press "Power Button" (just to discharge all phone components), put the battery back on the phone.
Press "Vol-" and connect to PC. Wait while windows detect the device and search in windows update for possible new drivers.
Windows won't find a thing but will take some time while trying...
After that you should be OK.
Just did similar to my phone and followed the advice in this thread - now sorted. Thanks guys you rock!
if u epic fail to manually force the drivers in just install android jdk open it and update it.

I had the same problem, after running several recovery procedures and kdz files, I finally was able to restore the phone to it's original ICS rom.
Download the files in the description and follow up the video.

hope it helps.
I need help! This is my first time I am doing this so I need all the help I could get!
I am planning to flash a custom kernel.(maybe later custom ROM,but for now only kernel) So, I know I have to unlock bootloader, install CMW and then flash. I see there are many tutorials so that will not be a problem(I hope) When I unlock bootloader I lose all my apps and data so I would like to backup it. I have TB but I am not quite sure how to operate it. Here is my explanation: I open TB, tick "Backup all user apps+system data", let it run and then what? Is there any folder on my phone that I should copy to my PC and then copy it back to my phone after I unlock bootloader? Question is, how do I backup and restore ALL of my data(apps,contacts,pictures,music,videos etc..)?
Second question is about ADB. I dont think I understand it fully. It says I have to have working and updated ADP and that is something I have to install. But I dont understand how to instal it. I got ADB in root folder for JB,someone told me that I could find it there. But how do I install it? In procedure for unlocking bootloader it says:"if you have the path to your adb defined" What does that mean? Question is, how do I install ADB and how do I use it for unlocking bootloader and flashing CMW,kernels etc..??
First part is ADB Driver

I followed the instructions and I think I already have those installed.. There was no yellow exclaimation signs, it recognized my phone as a portable device. Does this mean I have all drivers installed that are needed for unlocking bootloader?

you lose nothing by unlocking. unlocking means unlocking not wiping or reseting or formating.
adb is a mode you can enter the device. so the first time you do it , u need the adb fastboot files or the whole android sdk 32bit version. after that u can either enter adb mode from recovery option menu ,either again using adb fastboot.
the adb mode is a way to communicate with the phone using the pc. to do so , of course you need the pc to know when u enter adb mode. so for the pc to know that , just like with any device, it needs drivers. those are the adb drivers. u can either find the android drivers in the forum or download and install android sdk 32bit and inside the folder where you see the adb file ,create a cmd to easy open the cmd at that specific location.
you will need to bakup before you wipe or format all your data to install a new kernel + rom. if u only go for a kernel then u lose nothing, but u are not sure u will succeed in the first try , so .. backup them up to a cloud or external sd.
careful if u dont succeed with kernel , u will need lg support tool to restore the stock rom. if u go for a custom , u will just use same way in adb mode to install the rom.
edit: i dont know if u already have the drivers. open the cmd inside fastboot and write adb devices . if u see ur device then u r ok. try adb reboot bootloader and if it goes in adb mode then reboot and do the unlocking. dont forget the all in one toolkit. will help u now that u r a beginner in this.

first thing to know , when u talk about a problem is to identify the problem and what the "machine" does. if u dont say that u followed this guide, you did that and now when u do that the machine does that... i cant say anything im not magician lol. so now whats the problem ? the phone is working and u just failed the unlocking ? u failed the kernel installation ? ?!??
u r slow extract adb , open cmd in there ( i dont know if mine works for u , because i created in linux, maybe u need to delete the cmd.exe and create new. )
open cmd there and write : adb reboot bootloader. it goes in adb mode ?!

:laugh: Ok,lets start again.. I downloaded All-in-one tool.. Opened it.. Connected my phone.. Press 2 for unlocking bootloader.. I was asked,on the phone, do I want to proceed with unlocking.. I clicked yes.. Red letters showed on the phone and they said "download mode".. At the same time, on my pc, window was opened that said "found new hardwer".. I clicked cancel and pop-up message appeared "hardwer installation canceled, your device might not work properly".. On the phone the read message was still there,nothing happened.. I took the battery out, turned my phone on and thats it. Nothing on the phone was lost but I didnt unlock bootloader.

Hello,
I'm new and I just starting.
Everything going well, but when I want to install CMW I made an error, I don't unlock bootloader before the install, and now when I switch on my phone (lg p880) I see LG logo and nothing happens.
- I tried to "Update firmware through flashing the kdz files" by post on XDA, I have error when I press button 'launch software update' in KDZ_FW_UPD, error about Up text Ex mod2. I add my phone have root!
- I tried to unlock booloader in All in One but my phone don't have debbuging switch on, thats information show me.
- I tried in SDK Manager with fastboot, eclipse and drivers are installed but something maybe I do wrong and isn't work too.
- My computer don't see phone, when I connected phone to computer holding VOL-
How can I do something? How to install maybe orginal ROM, but I want to install Avatar ROM on XDA and this is the beginnig I read that to install the ROM I must have root, unlock bootloader and CWM.
I can go only to orginal recovery and s/w update (but there is nothing doing, when I connected to computer holding VOL- , my computer can't see phone, and I don't have connection with LG Mobile Support Tool)!!!
So now I have nothing
Please HELP me, I don't have phone now and this is terrible.

Regardless if you have USB debugging on or off if you plug up to your PC in download mode you can use the LG PC SUITE software that comes on your phone, or download it from lg, to revive your phone.
You'll need your PC connected to the internet for this
Just put in download mode
Plug into PC
Open pc suite
At the top click mobile devices tab
In drop down click "restore upgrade error"
If it doesn't recognize your phone you will need your serial number and your device model number I.e D959, D950, D955, D958, etc.
Sit back and relax this takes about 10 mins
This is the only method I use now to restore my device. Works like a charm for me.
when the phone is softbricked and usb debugging is off you cant install all drivers my friend.and phone no connected with anything.thanks for your intresting

Yes. There is a folder on your c:\program data\lg ....something or other folder. go into it and into mobile phone folder I think its called. I'm not in front of my PC right now. But you'll find the folder you need in there. Just put the stock .kdz file in there. It must be the same version or newer than you're on. Or was on when it bricked.
I've even actually pulled the .kdz files from there after I used PC suite the first couple of times. Used them in the lg flash tool.

I've noticed, by accident, when I did the factory reset method \ steps to get into twrp, but for some reason twrp wasn't installed and it actually reset my phone.... And caused it to boot loop due to what ever i did to FUBAR it. Factory reset defaults USB debugging back to off but when in download mode it didn't stop PC suite from "restoring upgrade errors" and flashing my flex back to stock. I've used it so much I now make sure my PC at work has it and the .kdz on it. My laptop has it and I have a flash drive in my truck with PC suite & .kdz on it. Lmao. Yeah I get a little ballsy sometimes and try just about anything. OK a lot but I always have a way back now.
my friend try this with pc suite and it stop in 0%.not run.and my interner connection is very good.why?
I have no clue. Try different usb cable if you don't have the one the one that came with it. I've noticed my flex and nexus 7 don't like some cheaper no name brand cables when transferring files or using adb. They seem to be fine with just charging. I use mostly my usb cable that came with my moto razr hd maxx. Only cuz it stays connected in the micro end better. And I have no clue what happened to the original.
Also make sure you have the latest LG drivers installed.
Sometimes to get the old "offline method" to work I would have to make sure no Samsung drivers were installed or Motorola drivers, Kies, or moto device manager. If any were I would have to uninstall them and the LG drivers. Restart Windows. And re install the latest LG drivers.
So not sure what exactly did the trick but I did all of it just to make sure and something helped. Try that. Don't plug in your flex till after LG drivers are installed and you have restarted Windows. I don't know but seems like what ever sequence or install or uninstall of drivers I've done now works all the time. Before we got bump I would go from 4.2.2 to 4.4.2 a couple times a week just to fool around a few days till something I modified or themed would bootloop me and I would get passed and go back to 4.2.2 and swear I'm not leaving JB till we have a custom recovery on KK. But my A.D.D. would get the better of me and I ,..... oh yeah I gotta run get some,.... oh never mind I'll .... huh oh yeah my A.D.D. it causing crack flashing syndrome. Lmao
I am on F340K Rooted Stock recovery Kitkat 4.4.2 V20D.
after changing my build.prop I forgot to set permissions.
Now I am unable to fix permissions through adb... although I succesfully Pushed the Original backup file from my PC..
I have two backups of Build.prop in my phone also.. One in system directory with the name of Build.prop.bak and 2nd is external sd card.
please advise me what to do?. I can access phone though Volume+Power = LG service Manaual (which is shown in ADB as Recovery device)
whereas Original Stock recovery Volume down+Power have an Android Logo with Red Triangle...
Is there a way I can install/ Push Some custome recovery Like Freedom Flex Bumped cwm or twrp to my phone? Fixing permissions through ADB Operation not Permitted or Permission denied error
Your LG Magna(H502) stuck on lg logo or bootlooping follow this guide to fix your device

Hello, I have the following problem. As in every other thing ive done to this phone (root, installing twrp, installing xposed) I always thought my model was LG-H502F. Though, my model is LG-H500F, I bought it from Greece, I recently bought Huawei P8 lite 2017 for myself and I gave my old LG to my father, he tell me that sometimes it lags and he is right. I think it lags because I uninstalled Xposed (flashed the uninstall zip using twrp) and also removed root, because he didnt need those things in his phone. The question is: Is there somewhere I can get the stock LG-H500F zip and what guide should I use? Ive been searching for a while now and can't find many topics related to LG-H500F. Thanks

I found this page earlier but can you import the kzd file to LG Flash tool? I didn't test this but, I guess it works. Thanks for replying

Hi, I'm in the same situation as Aneom7331, indeed I have a bricked LG Magna H500F and I'm trying to flashing a stock firmware. Where should I put the .kdz file in the lg flash tool 2.0.1.6? Moreover, the .kdz file has not a .dll file together with it, Thanks in advance
Someone have link to stock for h502y?
