Install LG drivers. It is necessary installing them as they will let your PC recognize your phone.

USB debugging enabled??

Restart your phone and laptop/both and see if it works.
I had the same problem and it was caused by rome kernel, flash franco (or fserve ) kernel and you should be fine
Guys, I have the same problem, so is there a solution ?
Thanks for your Help.

[SOLVED] [HELP] USB NOT working again?

Hi, I bought some months ago my LG Optimus 3D.
I rooted it, installed CWM recovery, and flashed a custom rom (after trying a bit ones).
But when I tried to connect my new-customized optimus 3d as a usb mass storage it didn't work anymore: my PC seemed like to not recognize my o3d, even if it installed the following drivers:
LGE Mobile Composite USB Device
LGE mobile USB Serial Port (COM47)
LGE mobile USB Modem
Anyway, I managed to flash the stock firmware with LG FlashTool. Everything worked well, but when I tried to connect my stock o3d to the computer... the USB was still broken!!
Then I sent the phone to LG; they said me they have reflashed the stock rom, and that my phone hadn't got any problem.
Anyway I got it back: I tried to reconnect the phone to the PC and magically the USB was working!
So, I rooted it and tried a few custom rom..... at the first time the usb was working very well, but after some days I got the same problem: now the USB doesn't work anymore, and I don't want to flash a stock rom...
Any suggestion? What should I do in order to fix my USB connection?
I tried to connect the phone with different usb cables, and in five different PCs (LG drivers were installed in every PC).
The PCs seem to recognize my O3D as:
LGE Mobile Composite USB Device
LGE mobile USB Serial Port (COM47)
LGE mobile USB Modem
instead of:
LGE Android Platform Composite USB Device
LGE Android Platform USB Modem
LGE Android Platform USB Serial Port
LGE Android Platform USB GPS NMEA Port
Android PlatformSooner Single ADB Interface
LGE Cosmo USB Device
LGE CosmoExt USB Device
(I got that list when I connected the phone after I've got it back from LG)
I dunno i am noobie on this, check my post count..
But try to disable USb debugging..
Yeah, I tried to connect the phone with both enabled and disabled usb debugging. I also tried to mount the usb through CWM recovery but nothing.. It doesn't work.
The last thing I've done before the usb stopped working was flashing the CWM touch recovery through PC...
Did you install the LG USB drivers?

Of course I did it!
The easiest way would be to uninstall ALL LG drivers.
Then reinstall after a reboot.

I don't think this will solve the problem... but I'll try!
The strangest thing is that LG FlashTool lets me flash a stock rom and a different baseband... So, it cannot be a hardware problem!
Ok guys I SOLVED THE PROBLEM!
The solution was to take out the battery for 10 minutes.
When turned on and connected, the USB worked properly!
P.S.: I don't know why...

[Q] Computer fails to install USB driver after installing ICS

I flashed ClockworkMod ICS on my LG Optimus P500, but I needed to install the baseband to make my wireless and mobile signal work.
When I connected my phone to my computer (Windows 7 x64) , it couldn't install the USB driver. I tried a few techniques like going to the Device Manager, and updating the driver, but it didn't work. Then I tried to use the LG Mobile Support Tool to install USB drivers, but it didn't work.
When I reverted back to my old ROM (Phoenix), and connected my phone it was able to detect the device successfully. So, I know that the drivers were always present, but it doesn't detect it on the ICS ROM.
Can someone guide me?
I'm pretty sure you have to enable USB support in the settings. Look under development and check the box.

Hi, the Android Debugging option is selected. In fact, I can see my device under ADB. But in device manager I see MTP USB Device, and Unknown Device under USB controller. Installing this driver: technoxide.blogspot.com/2012/04/download-lg-optimus-one-p500-usb-driver.html did not help.
latest drivers LGUnitedMobileDriver_S4981MAN37AP22_ML_WHQL_Ver_3. 7.2.exe

Cannot connect my phone to pc

Whenever I connect my phone to the PC I'm not getting the connecting options..like whether to use the USB mode or MTP device etc. This issue started after I flashed JMP Xtream rom 3 months back. I told my problem to the service center but they are saying that they cannot help me.
I tried using my friends data cable but still no luck. But whenever I connect the phone its getting detected as an unrecognized device. I can charge the phone but cannot connect it. Also USB OTG is not getting detected even by using apps like stickmount and USB host controller..
Im irritated with the prob and require some help...any solutions for this prob..Im currently using Suvi v12 rom...

Phone is not getting detected at all when connected with cable...Its still coming as unrecognized device...
Wifi is the only option available or using the bluetooth connectivity option....
But there should have been an option to restore those connection options back...specially after flashing stock rom using CWM...
Download vcom drivers
It may help u

Try reverting to stock rom or flash some other custom rom as drivers are unable to serve.OR you can (after making a backup) wipe all your data.....restore factory settings on your fone as dis will remove any virus or faulty setting(some system paths nt shown in general).
HOPE IT MAY HELP YOU.

Tried installing VCOM drivers long back but still its getting detected as unrecognized device...
Also tried restoring through back up of stock rom v2 using cwm but still no luck
Just now tried by restoring to factory settings but no luck again....
Instead of installing drivers on comp..are there drivers for phone and all??
"Run "regedit"and select the "HKEY_LOCAL_MACHINE/SYSTEM/MountedDevices" folder. See all the "Dos Devices" listed? You'll have one entry for each physically mounted drive (HDD or Disc) plus you'll have one show up for each USB drive you attempt to insert. Double click each device listed and seeifyou seetextsaying something like"U.S.B.S.T.O.R...". Once you find that device, right click it and select "Rename". Now change the drive letter to something unused... like Q: or something. Close regedit, disconnect the USB device and reconnect again.
This will fix ur problem:thumbup:
