Connect in download mode..
(Power off phone. Keep pressing volume up and then power button till downloading text appears on screen.)
Now connect to pc.
If it is not recognised as usb device then change your cable.
Else, remove battery to get out of download mode and enter in recovery mode after reconnecting battery. And restore any other nand backup or install different rom.

i've try put it to download mode but pc still doesnt say that unreconize device. then i put firmware.nbo of all other such as from wellcom, spi, cherry so my phone still say not correct file to flash. i've formated sdcard by my phone before go in to recovery mode. i also reinstalls window but the problems still there. i've tried serveralls usb cab as origin cab by wellcom, usb cab of sony ericson x10mini and a nokia cab but pc not connected to the phone. so every cab is good for connect my other android phone to pc and flashing. (i have sony ericson x10 mini pro, another android phone)
Take it to the service center

If it is not detected in download mode (I suggested download mode because it is independent of presence of adb daemon service running in background), then paarkhi is right. Please take it to service centre, as your connection port must have been impaired.
Wellcom service center is not in my country. As far i know, with froyo 2.2 there are lot of phone form motorola, samsung has a problem with connecting to pc. so some time my wellcom a99 too, but when it happen, I do a factory reset then its ok. but now factory reset does not solves my problem. and I cant flash any nb0 files. is there anyone faced the same problem with me?

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.

Hello people
I'm new here, in terms of asking questions and seeking help
I have the LG Optimus P970
A few days ago I made the update to ICS, and by proceeding with this page, hackmyandroid.com/optimus-black-p970-official-ics-update/3299
After that, not impossible to connect the phone to a PC, even the software update mode, it can not recognize, anyway to connect it just throws a slow charging.
Is there someone who knows what it is.
I'd love to go back to the old software, but there is no way to detect it pc
Sorry for my bad english
Thanks in advance
I forgot to say, before the update, and my computer still recognize the phone, connecting it over sony usb cable, now it is no longer recognized by the Sony USB cable, and I do not have original LG USB cable.
Perhaps this is the reason why a computer will not recognize the phone

I have the original cable, but still the same problem.
I have all drivers installed, I can transfer files between the phone and the pc, I can use the LG suite,
But I can't see my phone on the ADB console, I can't use smartflashtool cause the phone isn't recoginized.
yesterday I tried with lg cable, and wall charger, in both cases, said slow charging the battery, I tried on three different computers, I tried to reinstall the drivers, like the software blocked communication with the phone, just charge the battery.
If there was a way to put the software through SD card, it might solve the problem.
even the software update mode, the computer does not see the phone
Bro! For the softwaretool like smartflash, You need to boot into download mode i.e., You need to switch off the phone, plug in the USB cable connected to the PC and instantly press the volume up button. Then the tool will recognise Your phone. Try it and check once!
I tried it, nothing happens,
I go to download mode, but computer does not recognize it again
behaves as if the port is destroyed

Try to boot your PC with disabled driver signatures, or use a 32bit windows system.
try entering download-mode the following way:
disconnect your phone from pc
remove battery
press and hold Vol-up
connect the usb-cable (still without battery)
Now the phone should be detected as a serial-cable device an you can use the smart flash tool.
would have to be sound,
no sound when I connect the phone to the PC
Solved my problem.
Seems like windows automatically installs driver to the phone, but it partially works.
Unistall all drivers for the phone, or try on a new computer.
Plug the phone and cancel the driver search by windows
Install drivers for LG (unplug the phone before)
Turn it off
Plug the cable and enter download mode
And there is the phone recognized on smartflashtool.
I'm flashing a new one right now, thank you.
You do not understand the problem
there's no sign, no sound when I connect the phone to a computer, any computer, drivers were or were not.
As if something in the phone blocked communication between the PC and phone

Connection Problem with Mackay 2.999
Hey Guys,
first of all, sorry for my not so good English
I'am at Mackay 2.999 with last Kernel of his build and can't connect the Phone to the Computer.
It only install the LGE Mobile Composite USB Device, the LGE Mobile USB Serial Port and the LGE Mobile USB Modem on connecting to the Workstation.
I had test it on many Computers but the Problem is all the same: I can't get on my Memory or ADB.
I also had testet all modes under the setting point (MTP/PTP/mass storage device) and with debbuging on and off.
On my Workstation is the Last Version of ADB (1.0.31) installed.
Did anyone know the problem?
Did no one know a result to this problem
Hmmm my PC also can't read my storage what I did is go to cwm and plugged in usb cable and pressed mount storage it seems to solve my problem. I also did a cache and dalvik cache wipe.
Hey, I have found the result to this problem. You must flash another Baseband. Use from Nooby the V30 Baseband and it is solved.

lg optimus
hi frendz ,
please help me out
i'm using lg optimus p970..last night my phone memory get full and mobile get turn off ..now it wont turn on even battery is fully charged...only LG logo shows nithing else...
Hy guys , i have the same problem . I updated to 4.4.2 Nameless ROM and i can't connect my phone to pc . The only action that it's done : charging the phone and that's all . I tried connecting to another pc but with no result . An error appeared :" LGE USB Device - No driver found " .Before 4.4.2 i had 4.1.2 from CyanogenMod and with that ROM i had no problem connecting the phone to the pc . Any help ?
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

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....
Hello
so any USB connection is not working on my LG 4X on fresh installed stock soft [4.1.2]. On PC i got message ,,failed to install MTP usb device'' etc
Also i dont know how to turn on debbuging mode, maybe this will help? I click 7 times on compilation version and all it do is some jelly on screen (?)
I tested 2 usb cables and all usb ports on my computer what to do now?
I also installed LG PC suite and LG usb drivers from LG site.
Please help guys i need to put some porn on my phone :/
I have a similar problem, only that to me is the worst. When I connect my phone to usb, is only charging . I tried to put it in mode (S / W, bootloader, recovery) and nothing but charging.
