I have tried multiple times to install the USB drivers for my Optimus T (LGP509TN) running CyanogenMod 7.1 (6.5.8). I've tried installing, uninstalling - tried using the LGmobile agent to install... 5 of the 7 install fine but the LGE Android Platform USB modem and the USB Mass Storage Device fail. (see attached image called "usb installation")
When I turn on USB tethering, another USB installation routine runs and fails. (see attached image called "after turning on USB tethering". In Device Manager, I get a bunch of exclamation marks. (see attached image called "Device Manager".
USB storage actually will work - but takes a long time to kick in - and often crashes. Same with USB tethering. I've tried numerous different USB cables so that's not an issue.
Although I have an LGP509TN, I'm not sure if I should be installing LG509 drivers or LGP500 (as I'm running CyanogenMod 7.1 for LGP500). I'm not sure if there actually is a difference between the two. I've tried both and get the same issue.
Any direction would be sincerely appreciated.
Thanks,
Dave
Hi ,
I am also finding same problem. installed cyanogenmod
I took back up in ROm manager but not in recovery mod.
LGE android USB Modem fails to install.
Rest things are installing and working fine.
Help me out if you have found the soultion.
For you what i suggest is.
1. uninstall LG united drivers through control panel.
2. Re install it and turn on USB Debugging mode in your phone and connect it.
Everything will get installed. But not sure of LGE Android USB MOdem. IF you get soultion let me know even
I've tried everything that's been suggested. I've tried many different versions of drivers. Uninstalled, reinstalled.... Sometimes I'm even getting the Blue Screen of Death on my laptop when trying to connect the phone using USB. Wireless tether continues to work flawlessly. It's simply the USB connection that doesn't seem to want to cooperate.
I'm starting to think it might be a hardware issue - except that everything else with the phone works perfectly. I'm also going to buy a couple of new USB cables to try to determine if it might be a faulty cable.
1. Turn on USB Debugging mode
2. Connect USB
3. Then drivers stopped installing, turn off USB Debugging mode, but do not disconnect usb cable.
4. It will install some drivers and says all OK
5. Turn on USB Debugging mode (do not disconnect usb cable), and all drivers will be installed.
This is my method, and it worked for me.
Thanks for the instructions. The challenge I face is that the 2 devices never complete. (See screenshot.) If I close the dialogue, it tells me of the failure. When I switch on USB Debugging, it doesn't connect.

Experiencing similar problems with getting the USB drivers required for native tethering installed successfully. Running Windows 7. A walkthrough of clearing any existing drivers then reinstalling the proper ones might help. I've tried uninstalling via the control panel, system, devices area, but a complete purge/deletion of the drivers might be needed. Any pointers to a proven way to do so would be appreciated.
dude this happens to me week ago
first tell me are you running .32 kernals ??
if yes then flash it once aganin
or use .35 kernals it's best for cm7 series
When I tried to connect my rezound to my desktop PC the PC tells me the usb device is not recognized. It used to work where I can connect to my PC and look through files on my rezound, but it hasn't been working for a while. Does anyone know what the issue is? I tried enabling usb debugging and tried installing HTC sync and used some of the settings in "connect to my PC" section of the settings, but it still doesn't work. What I want to do is backup some files and eventually root and flash for the first time. I currently have an S5, but I want to root and flash on my Rezound. Thanks for any help.
Update: I got it work. I think it may have been a cable or port that wasn't working right as I used a different cable and usb port on my PC
I had adb working on my computer on the kitkat official rom, and now I updated to the rooted lollipop (Jasime 5.0 base). Root works, I have usb debugging enabled, and have tried following USB modes: Charge, PTP, and MTP (only ones that are available).
I can't get ADB to detect the device anymore.
edit:
I can get it working in TWRP, and I can get it working in PTP, but not MTP (weird). The ADB Composite interface does not appear connected when in MTP mode even though Android says USB Debugging is enabled.
You're supposed to use PTP in order to use adb. Glad you solved it.
OK to start I rooted using LGUP with a rooted stock 20j ROM.
I eventually flashed the 20L update but went back to my 20j backup because I found it runs smoother.
My issue is that my laptop will not recognize my device via ADB/Fastboot. I've tried re-installing the LG drivers with no luck. I have several LG devices that are recognized this is the only one that will not be recognized.
Any help would be much appreciated.
hm, can you provide some extra info on what you have done? In general what you have to do in order to make it accessible is the following:
Enable Developer Mode
Enable OEM Unlock
Try "revoke USB debugging authorization"
And then reenable USB debugging and try again
Also try with another cable and try some other USB port in your laptop or PC.
Sometimes some USB ports wont recognise the device unless you do some procedure to uninstall the driver for the specific USB port. For now just try to change the port and the cable.

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.
