LG P769 can't connect by USB - LG Optimus L9 P760, P765, P768, P769

I recently started to root my LG phone but it failed throughout the process. Now everytime I connect my phone via USB to my computer charges my phone but my computer won't show it or read my phone like it is not connected nor will my phone say it is connected to my computer. I have the drivers downloaded. Is there a way to fix it?

In 1990 to 2002 we have been using Serial Ports (COM1, COM2) and Parallel Ports(LPT1) for devices and they never gave connect problems like USB gives. USB works for some time and then the driver gets damaged or devices not recognized due to Voltage Problems, etc etc.
USB problems are very common these days. First thing you should try is, UNINSTALL DRIVER from PC and Restart PC. Connect PC to Internet, then reinstall latest LG Android Driver and connect phone with USB. Phone will install drivers for Slow Charging mode,...
...then select usb mode to PTP, phone will install driver for PTP,
...then select usb mode to MTP, phone will install driver for MTP,
...then select usb mode to LG Software Mode, phone will install driver for LG Sorftware Mode.
Now your phone is set for every mode you need. Hope this helps

No Connection via USB

Hello,
Few weeks ago I updated my Tablet to ICS with AiO-Tool by condi. Today I tried to connect my Tablet to PC to use some of the AiO-functions. But my Tablet doesn't show up in devices list in Windows. In device-manager there is no device that could be my tablet. Normally it says "Unknown device" but there is still nothing
Does anybody has the same problem or knows how to solve this? Thank you
djlars
Try to set usb debugging off. Then connect and re enable it again. If that doesn't work restart you tab in recovery mode let you pc install the driver and then reboot system. If your pc doesnt show any thing then try a other usb port on your pc last you could try is to use a device thats compitable with your tab like a camera or something but you will need the official kable from sony to connect the micro usb to normal usb...

Problems with MTP USB Device

I plug my phone into a USB port.
The first time I did so, an AutoPlay window pops up prompting me to run LGAutoRun.exe. I click to do so.
The LG United Drivers are installed onto my computer great.
But then an AutoPlay window pops up prompting me to run LGAutoRun.exe. I click to do so.
My computer attempts to install MTP USB Driver, but fails. According to Windows, the device is unplugged.
The AutoPlay window reappears. Repeat from the beginning of the paragraph.
What have I done to deserve such trouble, LG?!?!
Apparently the drivers installed directly from phone are not enough. In any case, I was observing similar behaviour *until* I installed LG PC Suite (which you should have been prompted to do too). It's stupid, it sucks but again, it's LG.
Install the LG drivers first. After that, when you plug your phone, it will be recognised as an mtp device.
Have you got Windows Media Player installed?

I tried two different versions of the LG United Mobile Driver, versions 3.7.2 and 3.8.1 on my computer. Same problems.

I do. Same problems.
Plug the phone, go to device manager in windows and uninstall the driver for the phone( or whatever shows up with the yellow triangle). Then unplug the phone and connect it back again. It should work. If not, uninstall the lg drivers and clean every trace of them and start from the begining.

Tried uninstalling the LG U2 USB Driver, then disconnected and reconnected phone. Same problem. LG U2 USB Driver was installed but MTP USB still shows up as unplugged.
Then uninstalled LG PC Suite and LG United Mobile Driver, reinstalled LG PC Suite and reconnected phone. Problem still occurs. I run LGAutoRun.exe and United Mobile Drivers are installed. Same problem. MTP USB shows up as "device unplugged" and phone keeps disconnecting and reconnecting to computer, saying drivers were not properly installed due to MTP USB being unplugged.
Interesting to note the phone is listed as a CD-ROM drive.

Install the software from the CD image. It will load the correct driver. After this re-connect the device and the CD image will show up for a few seconds and disappear. After this the storage will show up. That is how it worked on my device.

I have already tried what you said as I posted before. The LG United Mobile driver gets installed but the MTP USB Driver does not get installed due to the device being unplugged according to Windows, even though I have yet to disconnect the phone from the computer. The phone still says "Connected as an installer".
The phone is recognized as an F: Drive by Windows but LGE Mobile but keeps disconnecting and reconnecting every 20 seconds or so.
I am going to have to upload a video to YouTube to make things crystal clear.

Try a different USB port or cable. My P769 would not work on my USB 3 ports, but was happy on the USB 2 port. I had already installed the drivers and LG PC Suite and it picked up each mode just fine.
Plugging the phone into USB 2.0 makes the phone show up in portable devices, but LG Suite fails to identify the phone. I tried using both LGE Android Net MTP USB Device and MTP USB Device but they both fail. I have LG United Drivers and LG Suite installed already.
got thesame problem here mate..i search all over here and google the driver but still cant find any solution..this is so frustrating to fix this issue,,got install and uninstall the pc suite and driver many times but still cant get the solution..so what could be the fix????
no one can suggest..someone told me that maybe its causing the broken data cable but i have 3 cables now..
everytime i intend to install the MTP driver thing my pc always failed to do so,,saying that the filename,directory name or syntax label is incorrect..but i manually direct the search to lg driver folder but same error occurs..or there still other alternative apps that can transfer files without removing my sd to my phone,or atleast transfer files over the wifi..??
Any fix for this one? Already tried uninstalling, installing LG drivers, removed and reinserted SD card and everything. But still to no avail. It installs everything successfully EXCEPT USB MTP device which is the one I needed the most. Any solutions? Thanks!

You must be on 64 bit windows. Not even on 64bit, Still try this...
1) Uninstall LG Drivers, LG PC Suite and anything you see named LG. Restart PC.
2) Install latest LG Driver from this post (step 4)
3) Install Optional MTP Driver from this post (step 4)
4) Open Windows Device Manager (just to watch whats happening.)
5) Disconnect Internet (To avoid stupid online WDM drivers)
6) Connect phone with Usb and let drivers install automatically. Give it some time to install drivers keeping watch on Device Manager window.
7) Keep changing USB connect modes to all modes one-by-one on Phone and let drivers install.
You should see MTP drivers installed now. If this does not help, cant think of anything else. If this works, press THANKS button
EDIT: Connect USB at backside of pc, directly to USB on pc motherboard.

Thanks for taking the time to answer me mate. Already tried literally everything on what you just said above. Still no. I tried it on my brother's old vista laptop. One connect and it worked instantly! Lol.

The connectivity between my usb n phone isn't working

The connectivity between my usb n phone isn't working. My phone is currently softbricked and i can get to the s/w mode but everytime I try n connect it to my computer and start the lg tool it keeps resetting during the process. It says my phone isn't connected and ive tried two different types of cables. Is it possible for the usb drive to malfunction? i can't access cwd either. I also tried the latest drivers and also the one posted on this forum for the usb to pc. Thank you.
Google and download fastboot for l9 p769(whatever model) then open fastboot and choose option 5 (Depending on your model ex: option 4 for p768). Then try using lg tool.

[Q] [Q ; HELP] IMMEDIATE HELP for USB Debugging Problem

I have an LG L7 II Dual P715, and I was in 4.4.2 before, now I downgraded to Jellybean so that I'll be able to root it [I GOT THE KDZ FILE OF THE JB FIRMWARE FOR MY DEVICE FROM THIS LINK http://lg-phone-firmware.com/index.php?id_mod=21 ]. When I connected my phone to my laptop running windows 7 32-bit without turning on the USB Debugging yet and keep it in MTP connection, my phone got recognized immediately by the laptop (because i already had the drivers installed even before), but whenever I turn on the USB Debugging, when i connect it to my laptop, it just charges and it doesn't automatically enter the USB Connection Type where in i supposedly have to choose whether to use MTP connection or LG Software connection etc. unless I manually go to that section in the settings of the phone.
I have downloaded the driver of my phone. I even downloaded a universal driver of LG yet I still get the problem.
so basically, the problem is I CAN'T CONNECT MY PHONE TO MY LAPTOP IF IT'S IN A USB DEBUGGING MODE. I opened the Device Manager and I can't seem to find any trace of my device when it is in USB debugging mode Except if It is TURNED OFF.
What do you think is the problem with this? Is it my LG phone or the computer who has the problem? When I was in kitkat, I never experienced such issue, but when I flashed it back to JB, I cant rid of this problem anymore, PLEASE HELP, I badly want to connect my phone to the laptop while the USB Debugging is turned on.

If all you need is to root your device then you don't need USB debugging. You just need to use copy Framaroot's apk to your device and install it, and that you can do in MTP mode as well.

LG Zone 3 (VS425PP5) Drivers

Hello,
I have a LG Zone 3 phone (Verizon) and I'm unable to connect it to the PC for ADB. It's running Android 5.1.1. My PC host is Windows 10.
So far I've managed to enable Developers Options and USB Debugging already. In storage settings the USB connection is set to MTP currently. Sadly when I connect the cable to PC nothing happens (I've tried connecting other devices to the PC to rule out the cable problem and they run just fine, so I'm guessing it's not the cable). I've tried to install different versions of drivers but none of them worked, list of files and tools I've already went through:
adb-setup-1.4.3.exe (LGAndroidDriver_WHQL_ML_Ver_1.0_All_Win7.exe, LGUnitedMobileDriver_S4981MAN36AP22_ML_WHQL_Ver_3.6.exe)
Android_Fastboot__mini_ADB_Drivers.7z
LG USB Drivers All Phone For Windows.rar
LG_Mobile_Driver_v4.8.0.zip (LG Mobile Driver v4.8.0.exe)
LGBridge_Setup.exe
LGMobileDriver_WHQL_Ver_4.8.0.exe
LGUP_Ver_0_0_3_23.zip (LGUP_8994_DLL_Ver_0_0_3_23.msi + LGUP_Install_Ver_1_14_3.msi)
UniversalAdbDriverSetup.msi
Still no luck. I got so lost right now that I don't know how to proceed. Please help me figure out which drivers exactly I need to use for the ADB to work with this device.
