or it might be a problem with your usb cable that came with the phone. if u can, try getting another one and using that (they go for very cheap on ebay). Have u *unlocked your device lately?
I've tried many different USB cables none works for me. I got the phone almost 2months now already unlocked. Live in UK and its a ATT branded phone so I'm abit screwed.

Have you tried the microsoft answers forum (answers.microsoft.com)? They have some solution wizards in one of the stickies near the top.
Did anyone ever find an answer to this? I've had my focus since Nov last year and it's worked fine for me aside from some odd, and random nonsense.
I went to go connect my phone to my laptop the other day and realized it didn't see my phone. When I plug it in, the phone chimes and shows it's getting power, but both my laptops show nothing being installed, Zune doesn't load, and if I load it, shows nothing connected. Nothing appears in the device manager either. I get no error message.
the cord shows no damage, and it's been plugged into my wall outlet for awhile. I guess i'm going to see about getting another cable tomorrow and try it that way?
Was wondering if anyone else has had a problem with the cable going bad suddenly, or if something else could be to blame? I've been reading here, MS's site and anywhere else I can, and I find things ranging from error message, drivers not installing and other things. I just know it worked fine a few weeks ago, but now...nothing.
Had the same issue. My 4th USB cable did the trick. I wanted to throw it out the window

I don't know much about electricity, but every device I can remember having with a removable charger: instructions said Plug power cord into Device FIRST, then Plug into Power Source. Could leaving cord plugged into power source, thus reversing above instruction, cause a problem with the cord?
I am trying to connect via USB to my PC, not having much luck. I've tried several micro USB cables, and tried plugging them into every USB port on my PC.
When I plug in, and view "Devices and Printers" in Windows 7 32-bit, I can see a total of 6 LG devices show up:
LG Android Phone
LGE p999DW USB Device
LG Android (modem)
LG Android (NMEA)
LG Android (Serial)
Android Sooner Single ADB Interface
But literally every second some of them fall off the list and some reappear, sometimes they are all present for 1 second, sometimes none of them are present, and every combination in between.
I have no ideas left here. Uninstalled the LG driver from control panel, and reinstalled. Tried brushing out the USB port on the phone, as well as the old NES 8-bit blow method, no luck. Lots of cables tried all of which have worked in the past, no luck. Anyone have any thoughts?
Put the phone in apx mode by taking out the battery, holding vol +/-, plugging in the phone and waiting until the driver is ready.
Apx mode won't reconnect if dropped. .. I would guess a bad USB connector if the problem exists.
Also if the PC is overclocked turn that off. It messes with USB.

sound like a connection problem, either with the cable or your physical port on the computer
So it's connecting fine in APX mode, it stays connected in Devices & Printers. But I can't run the LG Mobile Support Tool from there, I've got to boot into Android. As soon as I boot into Android and connect USB, it's dropping the various device profiles in and out of Devices & Printers ever second.
Does it seems odd that I get a good solid connection in APX mode, but not when connecting with Android booted? Seems if the problem was with the USB connector on the phone, it would be an issue all the time.
Any other suggestions? I've tried going back to stock recovery and stock ROM, same issue. I'm really just trying to get the baseband update.

So you can safely say that the connector is good and cable its good. This suggests a software problem... either in Android or PC.
You can try the cleanup batch tool but I doubt it would solve the issue. Does not hurt to try though.

Are all of your Lg Drivers up to date?
No luck there either. Seems like a hardware problem, but it works fine in APX, only cutting in and out once Android boots.
I've been having the exact same issue.

Great, we've got strength in numbers!
So I've tried everything. I've flashed to stock recovery and OS, uninstalled the LG driver and reinstalled, multiple USB cables, different machines, USB debugging on/off, and every combination of things I can think of.
Sucks if if it's a hardware issue. Out of warranty period and I don't want to pay $130 or whatever the insurance deductible is for something so small... but I can't get 2.3.4 loaded without getting USB connected.
I'd be sure it's a USB connection problem, if I didn't get a smooth steady connection in APX mode. I've used NVFlash several times without issue.
Yeah I've only noticed it since i got the 2.3.4 update.
I've tried all my usb ports, and it will pop-up.
Last night i finally got it to let me decide to turn usb mass storage on but when I opened my computer nothing was showing up.
Just got a replacement g2x today after a long battle with my old one's usb port. When i was troubleshooting, I found that vmware and blackberry drivers can cause conflicts.
Try plugging in the phone and removing the drivers for all the LG devices you see in device manager.
btw... brand new replacement phone, if i move it the slightest bit while connected windows will play the disconnect/reconnect sound. I think LH just screwed up in the port design...
There's a funky greenish sticker around the usb port on this new one. Not sure what thats all about... cant tell if this is a refurb either.
Finally got mine to stop. I did a system restore on my laptop and it was good
@captmorganz the green sticker was on both my originals, and to check for the refurbished or not there is a code on the back under the battery by the screws that shows p999dw for original and something close but another letter at the end for refurbished, can't think right now since I've been at work for about 15 hours doing nothing and drinking coffee for the past 5 haha, excuse the rant.

Dear community,
I have a serious problem with my beloved Nexus 5 (black, 32GB).
Yesterday I recognized that the Device doesnt detect any kind of USB-connection.
Neither on a charger, nor on a computer/notebook. I tried several different cables and computer/chargers, but no differences.
When the device is powered off everything works properly. The Nexus is charging and I even managed flashing Android 5.0.1 via fastboot a few minutes ago (hoped that the system was the problem, but it doesn't seem so).
Device isn't rooted or modifed (recovery, system) in the moment cause of the os-flash.
Do you have any idea what the problem could be? :crying:

Hey @BrainChecker
first of all it doesn't seem to be a Hardware defect, if it's working fine, when phone is off!
Seems like u created some kind of problem with connecting to ADB or any update etc...
I would recommend to backup all stuff u need and then going to recovery and make a factory reset.
If all is working fine u already see there was a problem in system.
If u have still problems, it seems to be deeper (but don't think so), which means kernel, bootloader etc...
Much success!
CHEERS
Thx for the fast reply
I reflashed Android 5.0.1 now, but I have still problems.
Now, the device is charging normally, but still doesnt connect to computer. And the charging symbol doesnt disappear when I plug my Nexus off...

So check ur source for firmware and there's also the 5.0.2 out.
Try to flash this with a clean system.
Much success.
CHEERS
Thanks. Source is the official Google-Site for Factory-Images, MD5 is okay.
Where did you find a 5.0.2 for the Nexus 5 ? I'm finding only one for the Nexus 7.
Problem still is the same (Sytem reflashed), and even with a custom-kernel the are still there.
I'm really scared
EDIT:
a little bit more information. I reflashed 5.0.1, made a factory reset and even reflashed 4.4.4 (of course with a full wipe). Still problems.
Deinstalled all USB-Drivers (with USBDeview), changed the used ports on my computer and my notebook.
I tried custom kernel (hellsgod) and recovery (TWRP), no changes.
Still same problem. Phone is charging when plugged in (in the some cases, but NOT in every case). Charging symbol doesn't disappears after plugging off.
Computer doesn't detect anything. Neither in system-tray, nor in the device manager. But I recognized that for a realy short moment the "plug-in-sound" sounds twice (connect and disconnect), also for a very short moment the phone shows the debugging-icon...
USB in general seems to work in the system; I can use USB-OTG as normal.
I'm a little bit under stress, because I will leave Germany in a few days for several months. And 1.) I will need a working phone 2.) I don't want to spend money on a new one (travelling is very expensive...) and 3.) I don't really have the time and the nerves to work days on these problem...
:crying::crying::crying::crying:
I'd say that you have lots of old drives on the computer. Take them all off. I pulled out my hair over this. I took dozens out from old phones and my Nexus then it loaded a driver and a message came on the phone asking to recognise the computer...
Thanks for the tip, but it didn't work for me.
I removed all former smartphones, massstorages etc with USBDeview but my problem is still the same.
I recognized that on my dad's computer even the Windows-dialog for media devices opens...but theres still only the same short appearing of the mass-storage and debugging-symbol. Klicking on the Windows-dialog ends in nothing...
Dear XDA-community,
My Nexus 5 (D821 32GB) only charges while in bootloader mode.
Symptoms:
It spontaneously stopped charging in a normal way yesterday. By that I mean, that my Nexus 5 does not charge while switched on. While switched off, it loops the following way: it switches on, shows battery logo with the lightening, then goes to the logo that shows an empty battery (even though it isn`t empty, this logo usually shows loading progress, in my case it is not animated, meaning it just stays "empty"), after what the phone switches off and it goes back on again.
My temporary solution:
To circumvent that, I found out that it always charges while the bootloader screen is on (bootloader version: HHZ20h), and sometimes charges while in recovery mode (I have TWRP 3.0.3.0). So I used this method to load the battery.
My troubleshooting:
After extensive search on Google, the only reasonable thing that was said in one of the forums was that probably Android 6.0.1 detects some kind of danger to charging my battery and refuses to do it (I had the Xtrasmooth 6.0.1 custom rom with Xposed installed, stock kernel). Next thing I did was installing the app "Ampere" which told me that my phone`s battery, even though close to 3 years old, is in "good condition". Assuming that it is the OS that is messing with my charging issue, I completely wiped my phone, only leaving TWRP and an unlocked bootloader.
Please note:
I have tried all kinds of cables and chargers, even tried connecting to the PC to charge. My original charger works perfectly fine, and the charging port itself is clean. Like I said, the phone charges only while in bootloader. Battery life is also normal.
Question to you guys:
Here I am, with a fully wiped Nexus 5, ready to install a new custom ROM and being unsure what the issue might be.
Can anyone help me get my phone back to charging while the phone is on?
Is there a way to separately flash/work with usb connector drivers?
Thank you in advance :fingers-crossed:
Update 1:
Flashed latest factory image and returned phone to complete stock, problem persists. Why would the charging port not work while the phone is on?
Update 2:
Enabled USB debugging. Phone is not only not charging, but also cannot connect via USB to my computer as MTP (it is simply not recognized at all). In Windows Device Manager, it does not show up at all, even under "Other devices" (I uninstalled all possible drivers to see if it Windows 10 would react to it getting plugged in, it does not). I believe the problem is not the hardware of my phone (as it can charge and connect to the PC while in bootloader, fastboot commands work, could not manage to get the ADB commands to work in recovery), it must be some kind of internal driver issue.
Hi,
I have exactly the same issue. I have tryed all. I flash my Nexus 5 to Android 5 and the to 4.4.4 but nothing worked. Have you being able to fix the problem?
I also think this is not a hardware issue since I have changed the charging port and nothing happened and the same with the battery.

It could be a defective USB flex cable. There are 4 pins: 2 for charging, 2 for data transfer. It's possible for the phone to charge and not be recognized as a phone when connected to a computer.

5 pins...
Yes, there are 5 pins but I throught 2 were used for data, two for power. I admit I was wrong in this belief.

Hey guys!
I've recently been handed down a S6 and it worked perfectly until suddenly it would not charge anymore. Figured out that I could charge my phone through either my PS4 or through the Computer (Although it keeps disconnecting and connecting the USB again), and I can live with that, but a week ago my phone then started doing something that could literally make me throw it out my window in my second floor apartment...
Gear VR install wizard pops up every 5 seconds, during phone calls, while watching videos, during basically everything and it's super hard to even use the phone when you have to back out of the install wizard every time...
Now, I scoured through Google to find out what I could do but since it's most likely the USB port that got defect somehow, I'm pretty much ****ed when it comes to that -_-
So I then started thinking that if I install a custom ROM or at least get my phone rooted, I might be able to get rid of this Gear VR ****, but since my computer does not recognize the phone anymore, I cannot use odin nor ADB (I wish stock roms had the wifi ADB feature)
So my question is; Is there a way to root my phone through stock recovery or any other means that don't require a USB connection?
Thanks in advance.
As an added bonus, my phone has now started to completely turn off randomly sometimes, which is kinda annoying because while reading something on chrome, it just turns off >.>
I'm really hoping someone has a way to help me :/

In the s6, you can disable any apps without root using a paid app called Package Disabler Pro available on Play Store or warez. Use that! That's what most people who are not rooted do to freeze bloatwares & it works perfectly!

As far as i know, USB connection is necessary. try replacing the micro usb socket, you can find it on eBay.
