I've having a problem with my PC not picking up my phone when plugged up. It will charge, but that's it. I don't get the drop down box to select my connection mode. Here's my setup:
Android version 2.3.4
Gingervolt 2.0
SW version: VS910ZV7
Debug enabled
Default connection mode is internet connection
Connected straight to USB port (no hub involved)
I've tried taking the battery out for a few minutes and that didn't work. I've tried toggling the default connection mode, but that does nothing.
I'd like to upgrade my CWM, but can't because of this.
Any ideas?
***EDIT***
Well for some odd/unknown reason my USB connection is working again! I have done nothing to my phone since flashing Break Out ROM 1.1 a while back and the USB was still broken after that. So, while this makes absolutely no sense at all, I'm thrilled to have it back!

If you want drop down box to select connection mode then go to settings/connectivity and check always ask (if its not already checked) i dont think the computer will show its connected unless mass storage is selected and your sd cards show up on computer. When in internet mode its probably fine just run the program to install cwm recovery. Thats what i did to make sure computer was reading the phone. Someone else may have better input on the subject

I've had problems before when not using the original LG cord. Are you using something other than that?
"always ask" is checked, but it never asks when I plug it up to my PC. If I switch default connection mode to mass storage my PC doesn't pick up my SD card either. So mass storage nor internet connection mode works. It will however, at least charge.
Yes, I'm using an original LG usb cable.
Have you verified the SD Card actually works by going into a File Manager and seeing if you can read the files in your SD Card?
Yes the SD card works. I can browse the files on it with Root Explorer and CWM picks up the backup images on it.

Have you only tried 1 port on the PC or multiple? If you can, try a different port or a different PC.

I should have included that in my original post. I have tried every USB port on 3 different PC's. Two HP's and one Dell.
Any other suggestions? I've been searching the net for days now and can't find a solution. I'm beginning to think I have a hardware problem. Is there any chance this could be a software/configuration problem?
hello guys can you help me coz i cant connect my lg optimus 2x to my pc
when i connect my o2x is charging but my pc cant recognize it
i tried reinstalling drivers, change usb cable, change my OS from win7 to xp, flash stock rom ( cant flash because my pc cant recognize my o2x so i cant start flashing), use nvflash (my pc cant detect apx device)

please dont use any USB hubs...connect it to the USB port on the motherboard side....normally on the rear side for the Desk tops.....on the laptop all ports are directly connected normally...
secondly, what is your config? ROM?Kernel?please state your current configuration which can allow others to understand the situation.
Thanks
yeah i dont use usb hub i connect it directly i tried it on my laptop but its not working
my o2x dont say that usb debugging is connected it only charge
im on stock GB now 2.3.4 v20g
Don't want to hijack this thread, just got the same problem. (Not a complete noob here, rooted lots of different devices)
Bought a used 2x today. Froyo 2.2.2 german stock on it.
It just doesn't show the prompt that USB is connected
Tried:
- LG Mobile Driver from version 2.x.x up to 3.7.2
- on Win7 32 bit, Win7 64bit, Win XP 32 bit on various USB ports
- LG PC Suite obviously doesn't connect too
- checked/unchecked USB debugging, USB mass storage and all the obvious settings
- tried different cables
Would be really great if someone experienced could point us in the right direction.
EDIT:
After lots and lots of google I found out about a menu when dialing: 1809#*990#
With these options available:
CP Image Download
FET Disable
FET Enable
AP UART
CP UART
AP USB
CP USB
CP UART gave me at least a life sign once by saying that Windows wasn't able to recognize the device.
Is this issue really unsolvable?
Sorry for the bump, but I got some update.
when dialing the above mentioned 1809#*990# in the Port menu, switching from default AP USB to AP/CP UART gave me life signs.
After switching to AP UART I linked the Unknown device driver to lgusbdiag.inf located in C:/ProgramFiles(x86)/LG United Mobile Driver.
Suddenly it started installing it and is now recognized as: LGE Platform Android USB Device.
Once disconnected I lose USB again, I'm able to recreate the first steps though even in default AP USB mode by now.
The only thing I need USB for is for flashing a custom recovery but the only thing I don't have is ADB somehow : / Clockwork telling me: device not found.
Any help on this one?
any idea guys about my problem?
Have you tried my method?
After manually installing drivers with CP UART on, switching back to default permanently enabled access with default AP USB settings as well.
i tried that but it only charge
theres a weird thing in my cp when i switch to cp uart my o2x says it charging even i dont connect it to my pc or charge it
Ap uart - p990 / p999
I have LG P999. rooted and cyanogen.
None of the special DTMF dialing # codes is not working (also code changed from 990 to 999) (i sow some other in another posts)
is anybody know a way to change to AP UART by software (with eclipse...)
or with a special cable?
i need to use AP UART - meaning to have a serial com in AP(app).
Thanks,
Tamir
guys,
Have you tried to install MyPhone Explorer and try the same....it can connect your device via wifi,USB or Bluetooth....so some way should work....
any Android version above Froyo(included) should work....I use this always...one of very useful and bug free apps.

hi, when Rocket Rom 7 (ics) came out, i installed it. after doing this, when i connected my phone to the pc, the system detects the phone as Samsung_android and shows 2 removable drives in the system. however, if you click on them they dont work
it no longer detects my phone as GT-N7000
what i have noticed: when i connect the usb cable, the phone doesnt show "MTP connection" anymore... instead, it shows USB connected.
what has been done:
flashed rocket rom 10, nogo
reinstalled kies: nogo
reinstalled win7 (yes i actually did that even tho testing on other pcs showed the same issue)
the phone still charges and the only way i can connect my phone to d pc to view files is by clicking "usb storage"
any advice on this?
Uninstall kies, and just install driver (find latest from toolbox on my signature)
use different USB port, and dont use any extensor cable to connect device.

hi bro... didnt work... i dont think its the driver... its the phone... coz i tested another note, its working fine
My Galaxy Tab has similar issues. I believe it would be due to the architechture of the ROM forcing you to have to mount your device to your computer before being able to load the Device Internal SD, and the External SD.
Click USB Storage when it shows, this should pop up a window which has a Lil android dude, and USB Storage Message with a button stating 'Turn on USB Storage'. After clicking it, you can click 'Turn Off USB Storage' to unmount the device.
thanx for that.. hehe.. i stumbled across it the other day.. at least i can transfer files... but just dont like the fact its not showing...
I have this strange problem:
when I connect my Samsung Galaxy S Advance to my PC, the phone is recognized and I can start downloading my pictures, but, after a while, the download is interrupted and phone is not recognized any more...
Symptoms:
- Phone detected at first time is not detected any more after a while.
- After detection failure, if I try to browse my phone content, either in phone or SD card memory, Windows Explorer freezes.
Tried solutions:
- I've tried disabling and enabling all Developer Options on my phone, but the problem persists.
- Also, I've noticed that, while my phone is connected and recognized by Windows, the command
Code:
adb devices
returns an empty list of devices.
These are my system characteristics:
Phone specs
- Model code: GT-I9070
- Android Version: 4.1.2 (Jelly Bean)
- Baseband: I9070XXLQE (Germany)
- Kernel: 3.0.31-1122398 [email protected] #2 SMP PREEMPT Tue Apr 9 14:55:54 KST 2013
- Version build: JZO54K.I9070XXLQE
- Root: NO
- SD Card: 8GB working and recognized
PC specs
- OS: Windows 7 64-bit
- Installed Software: Samsung Kies, SDK
What can I do?
Thank you very much!
Try reinstall the Kies driver...

i'm not an expert but i would try disabling samsung kies, reinstalling samsung drivers, then plugging cable in different usb port, also could be faulty cable, dirty connectors @ phone, firewall... :fingers-crossed:

I have the same problem, the connection is lost when you turn off the screen.
Now I can't even connect the phone to the PC, it is not recognized...
See this thread...
Help please.
If you have wi-fi use samba filesharing.
The problem is with your usb cable-usb port-windows
Control panel -device manager -print screen with universal serial bus controllers

Unfortunately I don't have Wi-Fi.
Yes, the problem must be with my USB cable, port or Windows.
I attach the screen-shots of the device manager.

Then some PC problem. If you have time and nerves - reinstall Windows on that PC. But first try other USB port or something. Rescan with antivirus...

Unfortunately, reinstalling Windows on this PC is not an option.
I've tried to change USB port and the automatic driver installation gave the attached result: a partial error... still no recognition as MTP USB device
I cannot see the phone content in Windows Explorer... I don't know what I can do with the successfully installed device "SAMSUNG Android ADB Interface"...
I attach some more screen-shots of the connected and partially recognized Android device properties...
It seems that the modem function of the phone has been recognized by Windows, but I just need the USB storage feature!

Thank you, it worked for few seconds, then it did not find the device any more...
Thank You for your reply in that other topic. Now to this matter.
1. What option did you choose under lock screen? Swipe or None?
2. Even I have faced the problem and the solution i found was simple. This happens when our phone goes into deep sleep and to bring the files back you just need to unlock the phone. Just press the unlock or homescreen button and windows will start recognising the phone again.

Hi,
1. None.
2. The screen is always on, Windows loses the connection without apparent reason in the first minute or so of connection. Now is even worse, I've just connected the device and I can't explore the phone folders because Windows just stopped recognizing the phone...
This is what I see in Windows Explorer after connecting the phone: Windows seems to lose connection to it, failing to find files and folders...
unmount your card and try again

This is good and works for re-establishing the connection when it is lost.
I'll tell you if this is the final solution or if the problem keeps showing up after a while.

Did you scan your pc for a virus? If it works on other PC, then obviously it is a problem with the one you use.

Hi everybody,
I have a 64-bit PC with Windows 7 Ultimate Service Pack 1 and a Samsung Galaxy S Advance GT-I9070 with Android 4.1.2.
I can't install a driver in order to make Windows recognize correctly the phone when I connect it via USB cable.
I've installed and uninstalled Samsung Kies many times with no results. I've also tried some Samsung driver from Windows Update with no success...
When I connect the phone, it is recognized as a MTP Device and the driver installation starts, but always ends with an error, as shown in the attached screen-shot image.
What can I do?
Thank you very very much.
Note: in another PC with WinXP I have no problems.
Firstly make sure phone can run MTP (make sure if you delete MTP releated stuff in system you won't able connect it. Re-flash with Odin) Now if you don't have problem with phone then uninstall drivers & KIES from Windows. Don't just do a uninstall clear temp files, dll files, registry entries (you can use CCleaner) then install THIS DRIVERS.

Hello, thank you for your answer.
How can I make sure my phone can run MTP?
For the complete uninstall, is it enough to run CCleaner, uninstall Kies and then perform the Registry Cleaner in CCleaner?
Thank you

Did you root phone ? or installed a ROM or you just using it stock ?
I noticed something too; if you any have PIN or Password you have to unlock phone otherwise MTP not works. Unlock it and try too.
CCleaner will *probably* be enough but if you want to make sure go to regedit.exe and go to;
Code:
HKEY_CURRENT_USER/Software/
Then delete KIES & USB Driver stuff (don't delete system USB configs & drivers just Samsung's softwares )
EDIT: In start menu click to RUN (or whatever I don't now it's name in English, you're entering a text) Then write
Code:
%AppData%
Then delete KIES & Samsung folders and files.
I've just Updated the phone firmware from Android 2.3.6 to 4.1.2 with Samsung Kies on my WinXP PC.
I've deleted all Samsung Kies registry entries.
Now I'm going to install the driver you suggested...
Let me see results...

Have you tried to reboot phone? I lost mtp after charging phone over wall charger. Everytime I need to reboot after charging to get it connected to pc.

This may be a bit silly but is important to ask.
Was your PC connected connected to the internet while installing the drivers??
Did you unplug your phone while the drivers were being installed??

I've just tried to reboot the phone before connecting it to the PC, but I get the same error (see attachments).
Last year I managed to connect the phone to this PC, but, in any case the connection got interrupted after a while (see this thread).
I don't know what to do...
I had the same problem when i formatted my PC 2 days ago. I did some trial and error and it worked.
1. Dont use any USB Hub if you are using.
2. Remove the Pattern lock or any password security etc. Go to lock screen and select 'None'. (I dont know why but windows doesn't recognise if the device is locked)
3. Have Kies installed. Even new version worked for me. I used 2.5.13043_14
4.Connect your device with the USB cable (Should have MTP option selected which is by default)
5. Windows automatically recognises now and installs the necessary files.
P.S:- Remove the security pattern, etc. It really works.
If worked then pls reply.
Hello,
I've disable any screen lock on my phone and I've connected the USB cable to another USB port (a 3.0 USB port) and Windows magically recognized correctly the device! (no Kies installed, only drivers)
Anyway, after some minutes of usage (cut-paste of files). Windows stopped recognizing the device...
If I disconnect the phone and then connect it back, Windows still recognizes it, but I have few minutes until the device stops being recognized and no file on it can be read...
See attached pictures

Did you download newest version of drivers? I see in your screenshot it says 2012, on mine it is 2014.
Did you set Windows to gather drivers automaticaly from the internet?

This is how my PC recognizes my phone. The driver seems to be old, but I've configured Windows for downloading drivers automatically and that is all it can do.
Today, th PC did not recognized the phone at once. Then I unmounted and mounted back the MicroSD card and the PC recognized it.
But, after few seconds of folder browsing, the PC lost the connection. I'm thinking that the problem is the SD card.
Solved!
Solved!
It was the USB cable.
I replaced it with an original one and now it works.
Thank you everybody for your effort!
