SO basically a day ago my mac and pc both cannot recognize my Nexus 6 through USB. i tried using adb and fastboot but the phone itself is not able to make it self available to either computer. I know its on the Phone side of things b/c it does not connect on any computer. Ive used multiple usb cables and computers. As of rn i can live with it since my ROM is running fine and im not having any problems with my internal storage. But soon i wont be wont be able to live with it, it is a necessary feature for me to be able to drag and drop files from my computer to my Nexus 6. Any help would be greatly appreciated.

So boot into fastboot and connect it to your windows PC with a known working usb cable. What is the result of "fastboot devices"? Also does the device show up in device manager?

Well if you have ruled out cables, computers and USB ports, like it sounds that you have - it is most likely a USB port issue on your device (or something motherboard related.)

Check there is no obstruction on the port. Loose pins etc. But I would send it for repair to be honest.

Hi there, I could really use some help.
I had to reset my T Mobile Vario III and now when I try and sync it up to my pc, it can't even connect.
I get a "found new hardware" wizard and if I run that, I get this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

I can't see what the problem is as surely a hard reset takes it back to "just out of the box" condition? Therefore, I should be able to sync it up again as I did when I bought it......
......shouldn't I?
Any help most gratefully received.
BUMP
Anyone?
C'mon folks, I'm in pain here.
Just when I'd got it running nicely with some super progs and apps courtesy of my xda buddies, I did a hard reset for a particular reason and now I'm in PDA-limbo.
Everything else is working as per a regular hard reset, BTW.
So what's the prob? Do I need to download drivers or what?
The only thing I can think of is that the RNDIS driver on the PC has become corrupt or is missing.
All I can suggest is that you uninstall activesync from your PC, restart it and then re-install it if not with the very latest version which should be on the CD that came with your device. Restart your PC again and then and only then connect your VIII and see if the PC picks it up this time.
Good Luck and let us know your progress
C.
Thanks Stinkey, I'll try that when I get home (in the queue at the bank at the mo), hopefully it'll sort it out.
Either that or plug your sync cable into a different USB port, failing that (on yor PC whilst phone connected) go to Control panel, System, Hardware, Device manager and under Network adapters, uninstall the Windows Mobile-based device, then after that, unplug your phone then re-connect it. Try a PC restart if it does not connect after driver install.
Hope that works.
Thanks for the advice gents but sadly it's been to no avail.
Can anyone suggest a next approach?
BUMP.
Anybody able to help?
The fact that your PC is seeing your mobile as a different unit after a hard reset is a puzzle!
Are you using orig firmware or a cooked ROM?
Original.
Thinking about it, the problem didn't occur immediately after the reset.
I had it connected and synced up, then something happened - I can't remember what, either the pc timed out and went to standby or "the Mrs" had to log on to her side of the pc - and something got pi$$ed off along the line, hence these problems.
I'm thinking more that the pc is at fault somehow 'cos the Vario is working perfectly otherwise.
Then try a system restore to before the problem happened.
I have seen on other threads that one guy had a faulty usb cable and another had this problem when going thru a USB hub instead of direct to the PC.
Maybe the USB port you are using cannot supply enough current. The Kaiser starts to charge as soon as it connects and can drop out the USB port if it can't support it and this may start to happen at a later date if the USB port power supply circuit dies.
Okay, so this is my problem. I tried installing LG USB drivers on Sony Vaio NS230E running Windows 7 Ultimate to update my phone (some LG java phone) this seems to have started right after the installation, my USB mouse stopped working. Touchpad still works. I tried another mouse, same thing. Another USB port, same result. Rebooted, same thing. Uninstalled the new driver, nothing. I even restored the laptop to a point in 2 days ago but still it doesn't work!
I tried a USB flash disc on the device, works. Tried my phone (Nexus S) mount and reads. I had 2 mouses that the device already knew, when I connect them, the device says nothing, but the mouse light up. I tried connecting my wireless mouse to it, but on connection, it says USB device drivers not installed. Unrecognized device.
Please help, I really don't wanna 'wipe' and 'reflash' Windows...
UPDATE: The problem is fixed. I don't know why.
Ummmmm.....I'm no help, sorry.
Try opening the Device Manager and find any USB host controllers or any USB mouses or any USB devices listed that might have to do with a mouse or pointing device. right click on it, properties, and roll-back driver. You can also try updating the drivers. If that doesnt work just download the drivers from your laptop manufacturer's Website.

1 mouse, 2 mice ;-)
Did you download the drivers from the laptop maker's website?
Wait. Sorry. I had a mind block and was thinking you need USB port drivers lol.
Try connecting the mouse, go to windows update, and check custom updates. Or whatever its called.

Okay, this got really weird. I inserted a Windows 7 disc and had the computer boot from disc. And in the Windows installation wizard, the USB mouse STILL DOESN'T WORK! I'm clueless. Could this be a hardware problem?

I just got an LG V40 on T-Mobile. I have a 2015 MacBook Pro on Mojave that i had no problem using Android File Transfer with my Note8 or my LG G7. I cannot seem to get my V40 to connect to the MacBook Pro to transfer data via USB. Is there a good free alternative to Android File Transfer, or does anybody know the right way to get them to connect. I've tried all the troubleshooting steps on the AFT site that I've found.
SHAREit seems to work pretty well. I don't have any Apple products but I'm able to transfer files with coworkers that do.

via USB?
Android File Transfer is working just fine for me. I also have the 2015 MB Pro 13", on Mojave 10.41.1.
Was also functioning fine on my previous phone, an LG G6.
Have you tried uninstalling, then reinstalling AFT?
Does your V40 connect fine to a Windows PC?
Tried different USB ports or cables?

I've tried several different cables. It connects just fine to my surface book. I've uninstalled/reinstalled AFT multiple times. Installed the LG Driver. Wiped the phone. The computer will see the phone just not as a drive. It's like AFT is the only thing that can't see it

What settings do you have checked in developer mode? I've tried with Debugging on and off, MTP and PTP. I keep getting this feeling that i'm missing something.

Hi all,
Dropped my phone and the phone stopped responding. I tried replacing the screen but this made no difference.
Since the phone was just not turning on at all (no sort of response), I tried to replace the charging port after (after the drop, the sim card tray was damaged so thought the issue might be around here).
After I replaced the charging port, I managed to get the notfication light flashing (with a power source) and now it is solid.
When I connect it to my PC, I hear the notification sound when a device has been connected but unable to view any files or see it show in my PC.
I feel like I'm close to getting the phone working but not quite there yet. I am mainly interested in just recovering the data.
Any help would be much appreciated.
In this case, you need a screen, either on the phone itself, or an external one, and a mouse to navigate the options, if you manage to get the screen to work, enable USB debugging, run adb devices, if your phone shows up as a device (reference screenshot:

}
), you can run adb pull /sdcard/ to copy all the files from it to your PC, but if it shows up as unauthorized (reference screenshot:
), you need to allow usb debugging on the phone, then run adb pull /sdcard/ to copy the data.
And remember for the sake of god NEVER use MTP if you're copying more than one small file at a time, as it is known to corrupt large files, or large quantities of files, if you do not want corruption use adb pull

Thank you for your reply - do you have any recommendations here? Specifically for xiaomi 9t pro? I read somewhere an MHL cable would not work
Dropped my phone and it stopped working. Replaced screen, still doesn't work. Replace charging port and notification light started blinking and turned solid though I don't see it anymore.
But the phone connects to the PC - I just can't access the phone. Using ADB I get a serial number followed by unrecgonised.
What can I use for this phone to get some sort of display, and something to control? Based in UK so any UK links would be appreciated.

Well, unrecognized means ADB does not even know what type of device is that, that's not good.
Any dock for a macbook using USB-C should work, as for proper stuff:
https://www.amazon.co.uk/UGREEN-Multiport-Adapter-Ethernet-Compatible-Grey
https://www.amazon.co.uk/UGREEN-Aluminium-Delivery-Charging-Compatible-Space-Grey
These two should also work with it.

Hello, i can't transfer files from my S21 Ultra to my PC via USB cable. Samsung's cable is USB-C/USB-C but i don't have usb-c slot on my PC so i tried 3 different USB-C/USB-A cables (from Huawei and Xiaomi). At first the phone was connecting and disconnecting ever 2 seconds. I tried different slots on my pc, installed USD drivers for samsung that i downloaded from https://developer.samsung.com/android-usb-driver and tried some tricks from YouTube videos but nothing solved the problem. It's even worse now, PC doesn't even recognize the phone and only charges it without getting a prompt on the phone to chose "only charge or transfer files/photos etc". On device manager i got this:

Can you try a different computer? That is easiest way to troubleshoot. Maybe a friend's laptop? You already seem to have done the first correct step of trying different cables.
Another culprit is lint lodged in the USB-C port of the phone. You can pick it out with a toothpick or similar. The lint prevents the cable from properly and fully lodging into the port, no matter how many different cables you try.
If neither of these approaches fixes things, then perhaps you need to consider that you might have a broken USB port.

Had the same issue some time back.
Was able to get mine working with fastboot & adb alongside an older 2019 Samsung driver.
Also after you installed that, go and uninstall all the devices under the "Universal Serial Buss Controller" and reboot your pc.

This is either bad cable or bad usb port.
Also remove the "SUMSUNG_Android" in other devices.
Now that the pc can recognise the device means drivers are working.
