usb problem

I can believe my luck, receive an update notification but cannot install, my phone is no longer recognize by my PC, mini usb is gone but the phone is still charging...

I have the same prob.
Zune says, i should connect a phone. but its connected, butnt recognized. Its charge though.
(Windows 7 x86)

Go into device manager and see if it shows up there. Might be a driver problem. If that doesn't work, boot the phone in download mode (hold home+volume down+power) and if your computer recognizes the phone now and starts installing drivers, it's you computer, not the phone.

H E L P - bootlooping, COM does not recognize phone

Hi everybody,
ill try to make it short:
My 6p has entered into the bootlooping mode.
I have never unlocked the bootloader/changed ROM/kernal.
After I let it bootloop until the battery is dead it's changing from bootlooping into blinking red dot. Then when I charge it for a couple of minutes it comes back to life after 10~ min it's bootlooping again - so I have a window of possibilities to play with the setting. In that window I have used the "OEM unlocking" option.
In the bootlooping state when I boot into the bootloader and connect it into the PC the device doesn't recognize that it has been connected and a PC ,and the PC recognize a entry of new device but doesn't recognize it is a Nexus 6p.
this situation is the same when I connect the phone when it is alive.
I have installed adb and fastboot with this software
https://forum.xda-developers.com/showthread.php?t=2588979
with the 1.4.3 version it shows in the end of the process "0 files copied" and then I tried the 1.3 version and it showed that 4 files were copied but it also showed an error.
I have also downloaded ADB from google site but it does not work either.
When I try to open the powershell in a folder where I have downloaded an img and type in a fastboot command the computer doens't recognize any type of command.
So if anyone can help me ill be glad.
Thanks in advance,
Matan.

What is the new device identified as....Qualcomm HS-USB QDLoader 9008? Your phone may be stuck in EDL mode. If that is the case you need to search XDA and attempt solutions for that problem first.
Did you previously have your PC setup properly with the correct USB drivers and it was working OK, or just now trying to get your dead phone to communicate? If the former it may be the EDL issue above. If it was the latter, the communication problem may just be the drivers were never set up in the first place. Have you tried a different cable or port on your PC, or another PC?
With no access to the OS you will be unable unlock the bootloader or access to ADB because those have to be enabled FIRST in the OS, so there's no helping you here until you can actually boot into the OS. Do you have access to Recovery mode? Tried a factory reset? If you don't have recovery, that was a major omission.

PC doesn't recognize my phone (cannot install ROM)

Hey there guys!!!
Can you please help me with this?
Yesterday i tried to install a new ROM on my LG Android phone (My LG phone is not working properly, it has a reboot loop). I tried to do a factory reset without success -> the dead Android logo appeared :/
I put my phone in Download Mode and connected to the pc but Windows does not recognize my phone.. it says: "USB device not recognized.. the last USB device you connected to this computer malfunctioned and Windows does not recognize it"
I do not know what to do now.. when i try to flash a ROM with the LG Flash Tool it fails because LG program does not recognize my device..
PS: LG Support Tool recognizes my phone (it shows the model) but i cannot flash a ROM
Thanks!!:fingers-crossed:

Bootloop/ADB/Data Recovery - Phone Not Recognized With Correct Drivers

I am trying to recover the data from my old bootlooping LGV20. My drivers are updated. When I plug my current, working LGV20 into the computer, the phone is immediately recognized and the driver is listed as LG v4.2.0, the most current in Device Manager. The phone is labled as its model number in Devices and Printers. When I plug in my old V20 (which has full access to stock recovery and download mode but does not boot) the computer recognizes something is plugged in, but in Device Manager the device doesn't show up. In Devices and Printers the phone shows up, but as "LGE Android Phone".
Summary:
When a working LGV20 is plugged in, it is recognized and the latest 4.2.0 driver is used.
When the bootlooping phone is plugged in and completely off, it is only recognized as "LGE Android Phone"
Not recognized in Recovery mode
Because of this issue, I cannot use adb on the phone to recover my data.
The phone is stock, non-rooted, android 7, LG-VS995. I have the usb debugging option in the recovery menu though the phone bootloops when this is selected.
ADB installed via 15 second installer and SDK.
"ADB Devices" returns nothing.
When in Download mode, "Fastboot devices" returns nothing.
This issue was repeated on a second computer.
USB 2.0 and 3.0 tried.
The phone is recognized in LGMobileSupportTool
In Download mode the phone is recognized as "LGE AndroidNet" in Devices and Printers and as a COM41 port (changed from 7) in Devices and printers.
What do? I'm at a loss and it feels like I've tried everything.
Edit: I've successfully dumped the phone via LGUP, tried flashed a new image, phone is still bootlooping. Is there any way I can browse the userdata dump file?

Problem with USB connection (only edl works)

So I have this strange issue, when i connect my phone windows says "Usb device not recognized" and my phone is just charging without any notification for file transfer option. even tried usb debugging no results. When connected in fastboot mode windows doesnt even show usb device not recognized. no action in windows. I have tried almost all basic fixes and also have replaced the entire charging board. The bootloader is locked.... and i wanted to mod the phone but unfortunately it doesnt connect to pc.
