Hello everybody,
I've got a problem with my optimus black.
I flash this ROM http://forum.xda-developers.com/showthread.php?t=1984246, but I'm not satisfied of it and I'm want to reflash the V20N with smartflash tool.
But when I put my phone in S/W Upgrade mode my windows said USB Device not recognized.
I've done this twice:
- install/uninstall usb driver and LG Pc suite
- change usb cable
- change usb port
- change ROM
Nothing work I thing that my bootloader is corrupt because it's modified in the V28c.
Thanks for helping me

What version of Windows?
What version of USB Drivers? Try newer drivers.
Bootloader isn't be changed by flashing ROMs in CWM. ROMs only need to change from boot partition and upwards since thats all they need to change.

What do you mean by software mode ? You mean when the phone is wake up and i'm on Lg Home ? Because when I do it smartflash doesn't find my phone, but windows yes. I tried also to use the SOS recovery mode of B2C but it said that my software version was up to date so it did nothing.

I tried on windows 8 and 7. On twice I downloaded the newest driver 3.7.
I think a problem of bootloader because I flash the old version of V28c, with the .bin and .fls which had CMW inside, It was befor they release the .zip version. It's rewrite the bootloader no ?. And also because my phone doesn't wake up when I push on power button on the V28c, V20G, and CM10. I can only flash it because of rom manager and nandroid backup.
Thanks for help
Solved
After 2 day on this @"#[email protected]# phone, I find a solution work only on widows 7:
With the usb recognition I succed with this protocole,
1) Uninstall the Lg driver
2) Install the driver with B2C
3) Put the phone in S/W mode with the battery windows will say that it's not recognized,
4) Unplug the phone It will stay on S/W mode
5) Reboot Windows 7, and as soon as the desktop finish to load plug your phone
And miracle it's work. Sometime you need to do it 2,3, or 10 times.
Concerning the power bouton it still desn't work on V10A, V20N.... So I think it's broken, so I will exchange it with my operator.
Thank a lot for people who gave me some time.

Hi there, I'm new here but I have been following this forum for a long time.
Here's my problem:
I own a LGP990 with DJANGO rom. apart from the random stuck in the DJANGO loading screen which required me to reinstall it, it was all working fine.
Until yesterday, when I plugged it to recharge. The battery charged for a while and then got stuck for hours when almost done.
I unplugged it and try to turn it on but since that moment it always gets stuck at LG logo screen and when plugged it doesn't display any battery charging. I then tried to start recovery to reinstall from zip as I did every time it got stuck in the django loading screen, but recovery does not start.
No problem, I thought, lets smartflash/nvflash a stock rom and i'm good to go. Wrong, the phone won't even get recognized by windows, though I installed the driver several times (disabling driver signature as well) and running it as admin; i tried different driver versions, different usb cables... It does not even play that background sound when plugging usb devices...
I'm using windows 7 32bit.
That's it, I have ran out of ideas... anyone got one? (besides sending it to assistance, since warranty is voided)
little edit: whenever i plug the battery the phone start by itself!

I meant to enter recovery. If your phone turns on when you put in the battery, the power button is stuck in a connected position so to enter recovery remove the battery, press the vol- and then insert the battery. If you get your phone to enter recovery and reflash the rom I will tell you what to try to fix the issue.
1.)remove battery
2.)press volume - and volume +
3.)connect phone to pc via usb
4.)download apx driver
5.)(go to device manager install manually apx driver, select the folder where you downloaded and extracted apx ini driver file
6.)flash using nvflash
7.)enjoy.

in AIO you have an option to smartflash roms not nvflash. You need to unpack a KDZ rom and install the ROM via smartflash
all the instructions are in the op of the AIO toolkit

mmmmhhhhh..... change usb port, change cable, reinstall the drivers. other than that I am at loss
AIO tool has an option to install Nvflash driver. Its the last option in a different color.
Or you could try to reinstall LG driver. I just downloaded the latest driver from lg support tool today. It works fine.
And be noted that you have to hold down both volume up and down while plugging the USB cable to enter nvflash mode. Holding vol down while plugging the cable in will enter boot loader mode which is not the same thing. Remember to remove the battery first of all.

hey...ur problem solved??
I tried to update my LG P880 with LGMobile support tool yesterday.
After connecting the phone, I clicked on Start updating. A window popped up, telling me that it was downloading.
When it came to the update part, it lost connection with the phone. I did exactly as it said I should do (unplug, take out battery and put in in again, turn on the phone and connect it to the pc), and it restarted with the updating.
On about the same point as last time, the pc lost the connection with the phone. I did the same as last time, but now, the phone just doesn't boots into the S/W update screen.
The phone is NOT booting, NOT working to flash kdz, and it is NOT detectet as a phone, neither by the pc nor the LGMobile support tool, but my pc detects a device called APX when I connect the phone to the pc.
What can I do? And what is wrong?

LGMobile support tool needs the phone to be in normal mode (generaly...).
No SW or other, just turn ON your phone and connect it to PC.

Nothing is working
I don't get the SW upgrade screen when connecting to PC, the phone is an "Unknown device" og named APX under device manager, and the KDZ program cannot find the device.
Is it any other tings I can try?
so if its apx, you can simple flash it via APX mode with nvflash, right ?
(i remember when i rooting my Optimus 2X via APX , that flashed prerooted system.img... so you can try this method)

That's not a hard brick but a really bad soft brick (hard brick means you can't even turn it on in anyway).
Did you try with adb? Don't know if there's an option to but maybe you can delete /system etc. and then try to connect to lg software.
At least that's what I would do right now if you already tried every other method.
Edit: Please reinstall all drivers for the phone and the lg software manually.
Maybe a driver is incorrect (try that before the adb way)

I installed the correct drivers but nothing stays the same, when I want to list on the device adb mode does not detect it, what should I use key combination to enter ADB mode?
Try out every single mode you get into (S/W, LG recovery etc.) don't know which will get you to use adb. I for myself never had such a brick without having a backup, therefore I can't really help you at this point but try to get into adb or some recovery to install any kind of system.
Did you follow the instructions from a tutorial from XDA? Like the one for installing a kdz manually, maybe this'll work. Give it a try.
EDIT: Try the manual way to convert a kdz into a dz file as mentioned here:

and what excactly fails with KDZ flasher?
And well.... flashing JB ROM over ICS STOCK probably wasnt good idea...

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?
