Hi
I'm having some problems with connecting my P700 over USB. I have the official JB ROM now.
On my desktop computer, when I connect my L7, nothing happens. The phone starts charging (slowly) and nothing else happens.
I have installed/uninstalled the USB drivers several times, tried every connection mode, used different cables, and still no connection.
BUT my phone connects fine to my laptop computer, I just installed the driver and it works good.
The laptop has Windows7 32-bit, the desktop Windows 8 64-bit.
Is there anything I can try for the connection to work on my desktop without formatting it? Please help me. I've ran out of ideas....:crying:
Thanks

From Your phone..
Go to Developer Options >> Debugging >> Check
And...
Go to PC Connection USB Connection Type >> LG Software >> Check
Also check on "Ask on Connection"
Now try to connect Your LG to PC
If that sollutions not resolve Your problems..
Go to lg.com/nz/support-mobile/lg-Optimus-L7-LG-P700 and download LG software include the Drivers and Install ALL of it
And if Your problems still not resolve.
Try to flash Your firmware!
Hope this Helping You. :cyclops:

Hi vasquezalonso,
Did you resolve your problem. I'm facing the same problem, I have tried do install and uninstall the drivers several times, and the problems still working.
When I pluged my cell on notebook, the cell start charging, but the window don't reconize the cell as a device.
So.. I'm unable to root it.
Thanks..

The steps are good, you have to make sure you are in USB Debugging and connected for LG Software.
If your phone is not detected and there is no attempt to search/install drivers automatically by your PC, try installing the drivers in attachment. Now restart your PC and try again, it worked for me, hope it does for you.
I had the same trouble,I connected my phone with Lg software, it auto downloaded driver and installed
Is MTP activated? Go check in Settings>Storage, touch the three dot overflow and go to "USB Computer Connection". Make sure MTP is checked. You can also try PTP mode too. Good luck!
You have to install LG L7 driver on PC too. I think the name is "LG PC suit" or "LG mobile update"
Hello everybody,
last friday I plugged in my Galaxy S4 (i9500, rooted) with my usb cable to my PC, everything was fine. I shut off my computer, went on a holiday for weekend, used the cable with my laptop and my friends' laptops everything was fine. Now I came back home, opened my PC, plugged in my phone, it only charges! I cannot access to my files and stuff via neither My Computer or Kies. It only charges.
My computer uses Windows 7 x64, everything up to date, tried to uninstall Kies, Samsung USB driver, none worked. I tried using diffrent cables, usb ports too. Diffrent computers, no problem. My Pc, only charges
The thing is when I look into my pc's device manager it says "PCI Input Device". When I first plugged in today and it didn't worked it said "Android Composite ADB Interface"
Both had yellow exclamation mark on their symbols. I tried removing them, restarting pc and swiching users, none helped.
Any Ideas?
Thanks..
Problem solved
I removed all the drivers, put my device to download mode and plugged in, worked very well.....
Hey guys,
Just recently, my PC and any other PC Ive tried for that matter will not recognize my Note 3. I had Windows 7 and it worked fine for months, then just the other day it came up on the bottom as USB Device Not Recognized, and no matter what I do it will not do so. Yesterday, I upgraded to Windows 8.1 and still the same result. I have installed Kies 3, uninstalled and resintalled Samsung drivers and still nothing. I am running a custom rom in the stock slot using Safestrap...is it possible that that might have messed up something? Even when the cord is plugged into the PC, the phone doesnt come up with anything notification that it's plugged in, but it does say it is charging. If any of you have any tips or something please help because I am at my wits end.
Thanks
Have you tried with another cord?
Computer doesn't see device... Device doesn't detect plug in... Sounds like a bad USB cord

Yes, actually I have and still nothing...forgot to mention that in the original post.
It's a strange problem which leads me to believe that something has gone wrong in the phone, or that I caused something to go wrong by flashing a rom or three, since it did work previously. Unfortunately, I'm at status: Custom, although my Knox is 0x0.

Yes, this shows as disabled. What should this be?
Can't help you solve your problem, but last night I had a hiccup where I plugged my (17 day old) N3 into my computer in a USB2 port and ... nothing at all. (As if it were electrically disconnected - no "unknown devices" showing)
Tried it in a different USB2 port, and ... nothing.
Tried in in a USB 3.0 port - same computer, same OEM cord - and everything was fine. As far as I knew, nothing had changed on either end of things, although the previous evening I had used a different OTG cable for a USB key with the phone, and I had also had a automatic update of the Samsung Push Service on the phone. Nothing had been plugged into the PC's usb ports since it's prior cold boot. (Win 7 x64 Pro).
This morning (both PC and phone have been rebooted), everything is back to normal - both on the phone and the PC. Both the USB2 and USB3 ports all seem fine.
Ugh. Makes me nervous - brand new hardware.
Boot into Odin mode THEN plug the device in, let windows find the drivers for it then once that's done, reboot the phone regularly and see if it works then. It appears to be an issue with most to ALL Samsung devices, but this worked for my wife's galaxy S3 when the computer wouldn't recognize it and the phone didn't detect a PC connection.

Did you fix this problem?
Thank you! Worked perfectly!
I have the same problem, do you have any solutions ? Thanks.
I too have been struggling with this problem. The is no USB symbol in the notifications area on my phone whether I plug into to my computer at work (Win7) or at home (Win7), using a usb3 cable or a usb2 cable. Its as if there was a setting on my phone that allows recognition when plugged into a computer that has been turned off.Is there such a setting? I would love some help on this as well. Thanks in advance! I am rooted with towel root and have had no problems until last week. When I look in the device manager on my computer it shows :
SAMSUNG Android Phone
SAMSUNG Android ADB interface
I tried uninstalling the above and then plugging my phone back in and it re-installs the same driver shown above.
For what it is worth here are the drivers for SAMSUNG Android ADB Interface:
c:\windows\system32\DRIVERS\winusbsys
c:\windows\system32\WdfCoinstaller01007.dll
c:\windows\system32\WinUSBCoinstaller.dll
Should I be using different drivers ? Thanks|!
please help!
any solution yet? i have same problem, no usb detection and camera wont work i want to flash stock rom whit odin but i cant get the computer to recognize my phone...
I was able to fix the usb recognition problem. i had to do a factory restore. I lost root but gained usb recognition AND the Over the Air update to 4.4.4 and patiently awaiting the update to 5.0 hopefully this month!
Okay, Here my problem since my phone got drown. After fixed it with my way (Internet yeah), everthing seems work except Usb. The problem are when connect it via usb to my pc (already installed samsung driver) in notif of my phone doesnt show usb connect or usb debugging but it just charging like normal. Tried to flash via odin buit device doesnt appear and yeah in my pc doesnt said its not recognized (Usb doesnt recognized or something like that). Hopefully it will be fixed without bring it to service center.
Thanks before...

the device might have trouble enumerating especially in windows 8.1
plug it in as normal
then plug any other usb dongle in like a wireless mouse thats already been installed
this will force windows into enumerating the device
if it doesnt work then most likely the port is damaged due the water damage it suffered

it took me months to figure that one out - even microsoft and samsung hadnt got any ideas
its because windows 8.1 has changed the usb stack and requires that all drivers be digitally signed and has an identifer that the bios can read
this means some old usb device didnt work unless they met condition already although new drivers became available for most things but for some reason samsung havent updated their usb drivers in years (May 5, 2011 is last officall release) so im guessing thats why it doesnt fully work in windows 8.1 and im sure the problem is because its not properly signed so the device fails to enumerate unless you do the plugging in another usb device
other old phones work fine like htc and new samsung phones also work fine so its properly just a strange issue with the way the galaxy y handles usb

unfortunatly thats the only solution iv found for windows 8.1 - if you restart the phone or remove the usb cable you have to go through the process again of unplugging cable plugging back in then plugging any other usb dongle in after - its the only way iv found for windows 8.1 to enumerate the device

Hmm, seems hopeless for this matter
Will ask google for this classic problem or bring it service center.
Hey,
So I got my D802 today and I want to do the whole Root, Recovery, ROM shenanigans.
But for the love of god I cant connect the phone in MTP mode, so I cant Root, nor install a recovery.
I cant connect to the LG PC Suite either.
Any Ideas?
what connection type are u choosing after plugging it into the computer? are u running Windows, Mac, Linux? Windows will work with mtp out of the box but I think Mac and Linux need phone drivers installed. Windows will need drivers when you're ready to "unlock" using adb.

when you first plug in your phone it gives you the option to install the drivers needed to connect in the different modes, if not on the top right corner of the menu with charge/mtp/pc software it should have the option to install the drivers

you never said what connection type you're choosing on the phone after plugging it in. there are a few options and change how the phone is seen by Windows. some options won't have it display as an mtp device or as a drive letter in my computer.

Really Weird
I'm having the same issue. I'm running OptimusG3 v1.3, I've never had an issue with it before, I used MTP to transfer files yesterday, worked flawlessy, now it won't. I was trying to map the G2 as a network drive, I installed LGPCSuite, a couple of other software that should be inconsequential, and suddenly my phone says connected as MTP, but my laptop won't recognize or show the device in My Computer. I get installing device drivers prompts, I used the hardware and devices troubleshooter which told me 'LGE Android MTP Device has a driver problem' and LGE Mobile USB Modem has a driver problem. Reinstall device driver -> completed, but still not fixed. I installed LG's universal uSB tool or whatever, no fix. I have no idea wth is up (It's not a USB debugging accidental toggle either). I'll try uninstalling PCSuite. I though it would be more useful
