[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...

But windows automatically installs the drivers right? (if not found)

No...
It installs drivers if the device already has the same included...
Fit is not plug-and-play, which means you need to install drivers manually...or install kies...
Whichever you prefer...

Dont go for KIES .... !! It's a crap ..

You don't have to use it if you don't want. Installing Kies means you're installing USB drivers, you don't have to start kies everytime when you connect ur phone through usb. I've installed kies but never used it. I use it HIGHLY OCCASIONALLY.

Yup kies is waste of mem (if u ask me ) for drivers go to sammobile website registr n check our phn specific drivers its just around 25mb file dats easy if u dnt want kies

I found it easier to install drivers kies then uninstall kies

hey i am using the usb cable of galaxy ace. is it the problem? but i think these cables can be used on both the devices.

I use the same cable on 2 different blackberry's, my nokia 5310 and c3, samsung monte, and acer liquid metal...
So I don't think that's the problem...
Have you tried using a different computer?

yes i have triedon different computers also.. but its not working there too.

Hi.
I had the problem too. I did this to connect my phone:
1. Go in DownloadMode. Now, the computer must install drivers, like odin.
2. If the installation finished, hold down the Powerbutton for 10 seconds. It'll restart, if nothing happens try to start with holding the powerbutton again.
3. Then, if the phone is started, your computer finds the phone!
I'm not responsible for any damages!!!!

[Q] Full bricked and no USB

Hello everyone,
i bricked my HTC One S device. There's no OS on it right now, but i can access bootloader (says HBOOT-2.15, S-ON, unlocked, RADIO 1.15.50.05.29) and CWM Recovery (v6.0.4.8).
It should be no problem for me to install another ROM, but: I can't establish a USB connection.
I tried it on multiple computers, with the proper HTC drivers installed on each but the device won't show up even in windows device manager. When in fastboot mode and connected to an AC power supply it doesn't even say "FASTBOOT AC", but the usb cable is definetly not broken!
anyone got an idea?
thanks in advance

Maybe try USB OTG?

Lenovo A850 No usb option

Hi xda, I need some help here on my lenovo A850.
Whenever I plugged it to my pc, it don't pop up any usb connection option and my pc didn't even detect it.
I can't use flashtool since pc didn't detect my phone.
What should I do?
I've rooted it using framaroot and installed cwm using mtk uncle.
Should I just try and flash other rom via cwm?
Really appreciate any help from anyone here.
Have a nice day.

Do you hear the windows sounds of connecting / disconnecting devices? If not, your cable must not working...
Else, try installing the USB drivers from here.
You can install roms from CWM BUT if anything goes wrong, flash tool can almost always fix it.
So i advice you, before installing anything make sure that your phone can connect to flash tool.

Do not expect to connect to flashtool if it doesn't connect to your PC.
From what you are saying it seems to me that the cable or the phone or the USB port has problem.
Try these: (until you hear a windows sound or see the phone charging)
- Try an other USB port
- Try on an other PC
- Try an other cable
- Try mounting from Recovery?
You can also try installing the USB drivers from the link i gave you in my previous post...

Just to be on the safe side. Have you checked using another computer?

I cant try it on another computer right now :/
I got new cable and still when connect it via MTP i got information from PC suite i dont got this drivers :
http://www.microsoft.com/en-us/download/details.aspx?id=19289
But i cant install them... like i said “this update is not applicable to your computer”

And another info : when im trying to instal MTP drivers via lg pc suite i got error, even if device is disconnected.

Okey so on another computer also on windows 7 x64 usb connection working fine, so what the F... is the problem here?
