The connectivity between my usb n phone isn't working - LG Optimus L9 P760, P765, P768, P769

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.

Galaxy Gio [BELL] does not connect to pc

Samsung Galaxy Gio [Bell] Canada. (locked)
Device: GT-S5660M
Android Version: 2.3.4
Kernel version: [email protected]#1
Baseband: S5660MUGKG3
The device simply wont connect or show up on any PC.
Tried installing KIES (lattest - Kies_2.0.3.11082_152_4). Nothing shows up
Tried putting the phone in downloading mode and then in KIES selected emergency firmware update mode and still no device.
Tried using lattest Samsung USB Drivers (1.3.450.0)
Tried putting the phone in downloading mode and connecting it to ODIN which it does not show up in the COM PORT area.
Tried dialing : *#7284# to change the SERVICE MODE to either USB, UART
Including Toggling DBG MSG
Tried different USB ports.
All doing this with USB DEBUGGING ON and tried with it OFF.
There is no USB Setting in About Phone or in Wireless and Networks settings from the settings menu.
There are many other people with this issue I found but all possible solutions that I have been able to find are listed and attempted but to no avail.
Ive read that others are having no problem connecting to their PC seeing as theres modding / custom rom forums all over. So people are able to connect which leads me to think that this is a carrier specific issue.
THIS IS ONLY MY SPECULATION . NOT 100% SURE
I thought I could start this thread on here to get some more solid advice and help.
I managed to unlock my phone. Not that this matters but I still can't connect it to a pc.
Is there a way to flash my phone with the need of a pc?
Would clockworkmod recovery work?
Would there maybe be an .apk that can be used to install the usb pop up screen or to mount the phone and allow it to be shown on the pc?
Does anyone have any ideas..?
turns out it was actually the usb cable.
I was using a micro usb that came with an LG Eve android phone.
I borrowed my friends HTC Desire micro usb cable and to my surprise it worked!
I hope this helps someone else and stumbles on this thread.

LG P769 can't connect by USB

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

[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.

Never had similar problems with the USB drivers nor needed LG's tools, so can't help you there.

Samsung A50 SM-505FN Strange problem with port type usb-c

Hello,
I have a problem that the phone is not detected by windows, the drivers on the computer are installed and have been reinstalled several times. The only exception when the phone is detected is in download mode. In addition, I can add that once in several dozen connections, the computer finally detects it.
I have tried various original samsung cables and it does not change anything. I have android 11, and as you know, samsung has changed the way to enter recovery, requiring a cable to be connected to the computer. I have tried all the combinations to enter recovery mode and download mode.
When I was able to install TWRP, booting in recovery mode was normally detected by the computer. I have debugging options enabled. Anyone be able to help?

Yeah, that's strange.
Does adb recognize your device?
If yes, you can boot into download and/or recovery mode by using adb.
If not, try to connect your phone to another computer. Just to check, if it's an issue on the phone or the PC.

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.
