Hello.
Three weeks ago my Nexus 4 is recognized by my three computers (work, home and friend) like a drive. Now it is not anymore recognized by friend 's computer: I hear the sound of connection but no change in file manager. However it works fine on two other computers (home and work). In addition the Nexus 4 of my friend is always recognized by these three computers.
I tried to install N4 drivers on Friend 's computer. No change, my Nexus 4 is not recognized by friend's computer. I tried the debug mode too. No change. And the nexus 4 of my friend works on the three comptuters. Very frustrating .
These two Nexus 4 is updated with 4.2.2, in stock rom, not rooted, 16Go, v11.
Does someone could help me to solve this problem without saving my data and then restoring to factory values?:highfive:
Thanks.
I forgot to write that i used only one usb wire on the same usb port. To be sure that the problem is not the wire or the usb plug.
Do you currently have USB Debugging turned on? Turn it off and see what happens...the reason I say is that my work PC can either see is as MTP with USB Debugging off or through adb with it on - not both.
My Windows 8 Pro laptop at home works fine for both at the same time...worth checking out
Maybe try to uninstall the driver using the device manager?

Thanks for your answer. I will try your solution today. But I don't understand why the other nexus, unlike mine works fine on every computer.

Thanks i will try your solutions tomorrow. But these solutions doesn't explain why one Nexus 4 works on the friend 's computer and the other Nexus 4 doesn t work: same wire and same usb plug.
I plugged the nexus on my computer. And I unistalled the driver of nexus in my device manager unplugged and plugged again the nexus. And then let windows recognize the nexus and install his own compatible driver. Thanks nhatters.
The problem was that for run application named carbon I had to install in computer first the adb driver and carbon for computer. And this driver does not recognize my nexus which have not carbon (for mobile install).
i had the same problem few minutes ago .. i just turned USB Debugging on and voila the PC detected my nexus 4.
Aha i had the same problem i just lowered the notification shade selected usb device n selected camera option and reverted back to the media transfer and that fixed it
I am having the same issue but nothing seems to work and I dont even hear the connection sound in windows. I've tried uninstalling and installing drivers with sdk, device manager, and the other thing in windows which is callew dew I think and nothing no success, also I have tried to disable usb sebugging and mtf media storage and nothing. Is the only thing left to is buy a new micro usb cable?

Same problem for me on Windows 7. I have tried everything - different cables, different ports, enable/disable USB debugging. Even uninstalled drivers etc. It is getting detected on Windblows and is showing up in the taskbar as an USB device with a green mark. But it is not showing up as a drive or the MTP device. Frustrating to no end!
im gonna try to research in microsoft website which drivers are not originally installed in my computer and delete all the wird ones maybe some other driver from another hardeare like another cell phone or something is interfering. Hope I dont delete something that will make my computer not work right.
Same here, I can no longer transfer any files on to my Nexus 4 anymore. I'm using a PC and it no longer reads it. Only fast boot and adb on recovery works.

It's not the same because I've tried adb and nothing. Your problem can be fixed by modifying google drivers. In the other hand I tried a friends nokia phone with same usb cable and started installing drivers right away.. Mine does nothing, not even a connection sound just charging. so It's not the cable. I'm starting to think the micro usb port got damaged or something really wrong with the rom but still I've tried to see if reseting the phone works and nothing.
Seems like its an issue with 4.2.2. Since last week my N4 was acting very strange. when I connect to my pc; It would connect and disconnect every second. After checking in Device Manager; my Nexus 4 was listed under SAMSUNG Android Phone . I end up uninstalling it (plus check delete driver software). Then I rebooted my computer. It reinstalled the driver and now its working. Thought my wire was broke.
This worked for me, it shall work for everyone else
Open the start menu and type in device manager and click on it, it should npbringba window up. Now at the stop it should say android device or something similar, drop down that section and right click to delete "Google ADB Interface" which was for me should be for you also. After make sure you check the box in the confirmation to delete the driver. Reboot your PC plug in your device and enjoy!!!

Im aware that one or two other threads have been created with this same general question but one thing they didnt ask is what to do if you cant fix it?
As the thread topic states my Nexus 7 will not connect to my PC via USB (It is not seen at all, its not a driver issue I've tried). It will not charge when turned on but it was charging when turned off last night. When I checked this morning it said I had a full battery but after turning the tablet on it said I only had 60% battery. All the started happening after I charged it with a battery pack at work the other day because I forgot my charger at home (some people have had similar problems after using car chargers). It will let me connect a flash drive to it via USB-OTG. I have tried 3 different cables on 2 different PCs (One running Windows 7 and the other running Windows 8). I really dont know where to go for help anymore as Ive spent the past 2-3 days googling like a mad man trying to find an answer and noone seems to have one.
I would love for someone to really help me out and get some steps that could fix this, however, if its not fixable how do I RMA it? I cant lock the bootloader and I cant flash a factory image.
You say it is not a driver issue, but your symptoms indicate it is. I would start over with the removal and re-installation of the proper drivers.

I've uninstalled them. Every time I go to manually install them the guides always say to find where the nexus is and my nexus never shows up. If it was drivers it would still charge when its on. So how can drivers cause the tablet not to charge from the ac adapter?
Try Wugfresh's program. I had issues w/o it.

Thats the toolkit I have installed. Its also the "guide" I am following when it comes to drivers. I tried to see if I could make the nexus connect to the pc while in fastboot and nothing happened then either. Everything he says to do involves the PC actually seeing the nexus :/
Ive changed it from mtp to ptp, toggled debugging, went to different back ups, flashed a new rom, etc etc. I really feel like Ive tried just about everything. Someone mentioned in one thread about some specific code in the nexus being wrong and possibly changing it could fix it but I do not know how I would go about doing that.
I also originally used the Wugfresh toolkit and had problems getting the drivers installed properly on Win7-64. Ultimately, I think I installed pda.net on my computer and on the N7 and was able to connect after that. Haven't had a problem connecting since. Re-read some of the Wugfresh posts about driver problems. You should be able to get it sorted out.

I sent you a PM but I really dont think this is an issue with drivers. I have been able to connect the N7 to my PC perfectly before the other day. Never a problem at all. Now I have uninstalled/reinstalled the drivers as best as I could (currently I have the samsung drivers because they are the only ones that will install without having to verify that the phone is connected via ADB and I had them left over from my Fiance's GNex so they have been here all along when the N7 was actually connecting).
The N7 is not connecting to the PC at all. It does not show up in device manager. You cannot make an ADB connection to it. It has already been rooted and it is running the latest version of Paranoid Android. On top of that the AC adapters will not charge the N7 while it is turned on. Its like the N7 turns away any usb connection other than a USB-OTG cable while it is on.
Also I really do appreciate the help. This has just been really frustrating for me.
Hello,
Since yesterday, I have exactly same issue with my Nexus 7 3g.
Everything is working perfectly but computer doesn't see Nexus at all (nothig works Bootloader, ADB, MTP,PTP).
Charging is fine (looks like), USB HDDs, pendrives are working as before.
Reinstaling drivers, changing to PTP, switchin on/off USB debugging didn't help.
Checked : other Nexus connects to the computer without problems, so its not drivers issue.
I assume it happened after Nexus was connected to my car charger.
Does anybody have solution/fix for that ?
Unfortunately my Nexus comes from USA, can I RMA it in Europe ?
I feel badly for everyone having these issues. I feel very lucky I'm not having them. It sounds as if the microusb port may have been altered/damaged by certain kinds of connections, like the battery pack or car charger. I don't know why this would happen and my own car charger (Moto oem for my Bionic) has worked fine on the N7. I did pick up the usb cable attached to my pc one day and created a static shock to the connector. Since then, that bank of 4 usb ports will not show either my N7 or bionic, but my usb mouse, keyboard, and printer work with them. The other bank still works, as does the pci port expansion card and my front ports. If I do have a glitch with the pc connection, I restart both the computer and the N7 and then it works. Sorry I don't have a solution.
I also assumed a damaged/fried USB post on the Nexus 7. There are 2 data lines and 2 power lines in the charging socket I think. If the power lines are damaged, usb otg may still be working. Its also tying in with the use of a power pack.

Have you tried switching between MTP and PTP and seeing if that works? If I used the PTP setting for the USB it shows up, I can then move files onto the PICTURE folder and once there move to another folder while using the Nexus.

Wow or strange should be more of the reply. I have done this before but it never worked. Thanks for the help. For anyone else needing help here is what I did. First opened the Nexus Tool Kit, then Full Driver Installation Guide, launched USBDeview, then - In particular look for devices with Vendor ID - "18d1" or... "04e8" - Simply right click these devices, and select the option to: - "Uninstall Selected Devices", final step unplugged the device and plugged it back in and it worked. Also MTP enabled USB Debug unchecked. Thanks again...
-AkWingnut
Tried this and haven't had any luck so far. I'm going to try pdanet or samsung drivers again later today and post results.

Bump!
I'm experiencing similar issues with my Nexus 5. This is the only thead I can find that has a similar problem. My Nexus 5 worked on SlimKat, I flashed stock L Preview, now my device won't charge when it is powered into the OS. Bootloader works fine and charges when turned off. I upgraded to 5.0 which came out today (Yay!) and the problem persists.
Have any of you lads or ladies had any updates?

In my case it was a hardware trouble. Fixed by motherboard replacing in official service centre.
I tried to connect my nexus 4 to my PC , but it would not recognize it under my computer like it should so I could drag and drop. I tried mounting it as MTP and PTP and neither would be recognised.
I ended up transferring my pictures using adb, but I don't know why it didn't work the standard way.
Anyone have any ideas?
Have you tried using drop box? It's really simple and automatic. Just set it to upload only on Wi-Fi

I've used it before but I want to know why the nexus 4 was not recognised by my computer
Is Android debugging on?
Is it having trouble with installing the MTP driver ? Try turning off USB debugging, I couldn't get MTP to work until I did that.

Maybe you've got the same problem that we have here: http://forum.xda-developers.com/showthread.php?t=2005437
Maybe you try:
A different USB port
A different USB cable
Uninstall existing drivers + installing the drivers again
A different computer
And if all that didn't help you can join us in the above mentioned thread. We don't have a solution yet but maybe we can draw some attention to the issue.
All the driver seem to be fine and the nexus 4 is recognised via adb. It used to work before so I don't what's wrong.
Edit: yes USB debugging was on
Ok, but that's actually good! What happens if you plug it into a different usb port?

It says your device could be faster with USB 2.0 and then it is not recognised.
Now that's really odd. Have you tried a different USB cable?

But you have seen your N4 in the explorer before, right? I have seen my N4 on my GFs windows machine as Nexus 4, not as a storage device.

And what happens if you double-click it there? Can you get your pix then?
Edit: I didn't find my N4 as a storage device, so you can't find it as a letter in your explorer but a real device.

If I double click it it takes me to nexus 4 properties. My nexus 7 does not show up in my computer either that's what bled me to think it has to do with 4.2
Edit:nevrmind its not 4.2 because I just connected a lg motion which is running 4.0 and it does not show up either
Maybe someone with a win7 machine can chip in here, since I think it is a windows problem. I am on a linux laptop, so I can't really help you there. But good luck anyway!

By George, I fixed it I went into device manager I right clicked on SAMSUNG android phone then nexus 4 under that section, then I clicked update driver. Then I clicked on browse my computer for driver software after I clicked on let me pick from a list of device drivers on my computer and I select mtp. The all of a sudden auto play came up with my device connected as a camera (ptp)
Now all my phones show up under my computer
MTP uses a completely different driver from ADB. So you can have one working but not the other.

I have no clue sometime when I connect the nexus 4 it shows connected as adb composite device and sometimes it says mtp.Now everything works though it took me a while but I fixed it.
Want to start this by saying I'm pretty sure this is a pc issue rather than phone issue, I've had similar problems with every android I've owned. I installed drivers through the Nexus 4 toolkit and the tutorial by thesmokingandroid, my PC doesn't even acknowledge the phone. I get the beep when it connects and disconnects but the phone doesn't show up anywhere like my computer or device manager at all. Like I said my older phones would connect most of the time but almost always randomly disconnect/connect. I feel like it's likely a driver thing, never had problems with my iPhones or other things like mouse or keyboard. Is there a way other than a clean windows install to just clean my pc of any android related things like SDK or drivers? Also it's a custom built pc with 5 ports running win7, no ports will work. I added an in tower sd hub and feel like the problems might have started around then but I'm not sure on that. Any suggestions would be nice, not being able to connect my phone is an issue with no removable memory...
edit: Wanted to add that sometimes when I only have my mouse, keyboard, and Xbox controller connected I get those little connect/disconnect beeps at random and the bubble that says this device can perform faster. I'm pretty sure my ports are 2.0 too but I'm not sure how to check that.

I having the same problem. When I'm in fastboot mode my pc doesn't show my phone but when my phone is powered on it shows up on my pc. Anyone know what I'm doing wrong?
Anyone? I'm ready to try reinstalling Windows but would really like to know if there's something a less time consuming I could try first. I can't root or anything so I'm going to have to try something soon.
Same thing happens to me a couple days ago.
My laptop recognized the phones, but it showed nowhere in Device Manager. Adb could see my phone, but as soon as I went to bootloader, my laptop said An USB port is unrecognized
SOLUTION: I use Nexus Root Tool Kit and Google NExus 4 Tool Kit to REMOVE the nexus 4 driver, everything related to nexus 4 is removed. I only used these tools to uninstall the driver, not to install them.
Then I turned off the Windows 7's Automatic Update Driver by Window Update (or some similar names). This is important, because the driver that windows install autimatically doesn't covery the Bootloader Driver. I dont remember how exactly I turned the Automatical Diver Update off. Maybe when the popup "unrecognized USB" appear, I pressed it and there was an option to do that. Or you can search google.
A link to turn the Windows 7 Automatic Driver Installation: http://www.sevenforums.com/drivers/82054-turn-off-windows-7-automatic-driver-installation.html
Restart my computer after that. THen download driver from this http://forum.xda-developers.com/showthread.php?t=2010312 ONly the driver.
THen Install it from DEvice Manager by plugging my phone again.
Finish.
I had the same issue,here's the fix:http://forum.xda-developers.com/showthread.php?t=2036400
In my case,there was no wpdmtp.inf file in windows/inf,hence device wasnt recognised.
I'll give that a shot when I get home thanks.

Yeah, what causes so much trouble for me is the Windows-7-automatic-driver-installation. It helped me sometimes, but not with the NExus 4 :|

If you have an unlocked bootloader use this tool to lock it: https://play.google.com/store/apps/details?id=net.segv11.bootunlocker
To unroot use the permanent unroot feature in SuperSU.
Order is important since the Bootloader tool requires root.

thanks. i installed the android sdk and java jdk but still have the problem. i believe the problem is with the phone 100%
my nexus always shows that it's charging on AC whenever plugged in. doesn't matter if it even is to AC or USB. the phone shows up as unrecognized device with a bang in the USB section of the device manager. on some computers it doesn't even show up.
i tried on my macbook pro and it doesn't even show up there but in every case, the phone charges.
wondering if there's a switch or toggle somewhere that will turn it on and get it working
i'm going to install a windows xp VM as a last ditch resort and see if it at least shows up there.

Make sure your device is on MTP and try an other data cable which has no missing/broken data wires inside.

yep it tried on mtp and ptp with 4 different cables. two original nexus 4 cables, one nexus 7 cable and a blackberry cable. they all work with my other nexus 4... just not this one.
the windows VM didn't work unfortunately.

That is strange, it should work with the Windows Virtual Machine.
Maybe it is to do with the standalone machine using it in the same time.

Same problem here. USB is not recognized using my Nexus 4 ( it used to be recognized on two PCs, but no longer), but another Nexus 4 connects perfectly. I can only charge a USB rate on chargers that used to charge at ac rate. I've tried everything, and more than mentioned in this thread.

Hi guys,
Seems that I've got the same trouble. Got my N4 (stock ROM, 4.2.2) a couple of weeks ago and everything was ok - connection as MTP, connection for debug and so on. But yesterday I connected it to my PC and found that the device indicates charging but not USB connexion. So I've tried to reboot PC and N4, tried other cables and 2 other PCs (my with Win8, and those with Win7 and Linux Mint if matters). Other devices are ok (Huawei Honor, N7, Milestone2).
The phone just doesn't detect USB connection - in both MTP and PTP. Then I tried to plug in wall charger and connect back again to USB. AND IT WORKED! The phone detected the connection so I was able to mount it and detect with adb. I thought that the problem was solved but when I connected it next time - same ****. This time nothing helps (most likely that there wasn't any casual relationship between wall charger connection and temporary fix...)
What options I've got now? Try to root the device and look into syslog to detect if it's a software issue or disassemble the device and try to find any defects on USB port?
Thank you,
Alex

So I've tried to reboot PC and N4, tried other cables and 2 other PCs (my with Win8, and those with Win7 and Linux Mint if matters). Other devices are ok (Huawei Honor, N7, Milestone2).
The phone just doesn't detect USB connection - in both MTP and PTP. Then I tried to plug in wall charger and connect back again to USB. AND IT WORKED! The phone detected the connection so I was able to mount it and detect with adb. I thought that the problem was solved but when I connected it next time - same ****. This time nothing helps (most likely that there wasn't any casual relationship between wall charger connection and temporary fix...)
What options I've got now? Try to root the device and look into syslog to detect if it's a software issue or disassemble the device and try to find any defects on USB port?
Thank you,
Alex

I got mine to work by using a 2 into 1 usb plug. The kind that comes with portable CD writers. Once I got it working I reflashed stock 422 and the problem is gone. Turns out it was a bad flash from the previous owner.

Thanks for advice. During this day it worked properly twice - the phone just started detecting connection. No obvious reasons for that... I got a new device with stock 422 from amazon and haven't flashed or event rooted it. How do you think, should I try to flash it with official 4.2.2? Now I can say that it's most likely a software issue.

I'd say try a factory reset first and see how that works.

Tried it out - the result is the same. Now I can not even unlock the bootloader to reflash 422... Btw I didn't managed to find a 2into1 cable but checked if the same trick would work with USB hub with external power - it works really better. The device can detect the connection almost all the times and I can see it listed in adb devices and as a mounted storage. Though in fastboot mode this doesn't help. Device remains unrecognized.

well if you're getting a connection to the computer but not in fastboot, your drivers might just need removal/reinstallation.
once you get it going, reflash the stock 4.2.2 from google and see how it goes.
if that doesn't work and you can get it going, get it replaced by Google.
if you can, try it on a mac.. they don't need the drivers installed. just run it all from terminal.
Okay, I've managed to track down the issue...
Once I got it available for fastboot I've unlocked bootloader and then flashed with Cyanogen. The problem remained but I could get dmesg output for plug-in event. I've managed to get logs for problematic case (doesn't detect USB data connexion) and for correct behavior case (when Android detects USB data connection).
No sense to put the whole log pieces here just a brief quotes.
For correct case:
Code:
Avail curr from USB = 500
For incorrect case:
Code:
Avail curr from USB = 1500
USB module firmware tells the system that it has detected data-connection and enabled low-power mode (500mA). In this case Android initiates mtp and adb:
Code:
<6>[62539.001178] adb_open
<6>[62539.001269] mtp_bind_config
<6>[62539.001422] adb_bind_config
And in problematic case USB module firmware incorrectly indicates for the OS that there are only power-connection (5V/ground). I cant say exactly where the issue is but there are only two options - bug in USB module firmware or physical fault of connection (pins, bus or whatever else). Anyway I've to replace USB module or just go with it and use adb over network (the matter is that sending the device back to Amazon seller from my country would cost me 1/3 of the purchase total so I consider that just unreasonable).
Thanks to LG - for my money I got not only a box with device but also whole lotta fun =)
I'm at a complete loss here guys, hate to even ask this. So I tried to connect my 6t to my Windows 10 PC and the PC won't even RECOGNIZE that anything was plugged in! No sound and not even an entry in device manager. I even went as far as to reinstall Windows 10 and no dice. I installed the One plus driver from here on XDA and they are unsigned drivers, so I disabled driver signature enforcement and the drivers are now on my PC, but with the PC not even noticing something was plugged in it's no use.
Some info.
Using the red USB C cable that came with the device.
Plugging it into a USB 3.0 port on my PC.
Installed the OnePlus driver with enforcement disabled.
More info? Let me know! I'm lost here.

Try a different cable. I come from the land of pixels where you'd be surprised by the amount of headaches cables have caused. If that's doesn't work I'd be stumped as well
You have to enable USB debugging and change USB configuration to transfer data..

I did both. Doesn't work for me :/ In Android pie, is there some setting to enable MTP other than developer options? I don't even get the heads up notification on my device. I'll try connecting it to a USB 2.0 port instead of 3.0 and see what that does.

Just ruling out all possibilities (have run into this myself on other phones) :
Have you tried another port on you PC?
FWIW,I'm using a cable from either an LG or Samsung & that's working for me.
The device is seen & I got the pop-up on the phone after toggling the associated USB options in Dev Options on the phone.
Was able to execute ADB commands for an Immersive Mode app & to use the no-root ADB Uninstall commands.
I just used my og pixel xl type c cable and it instantly installed the drivers and recognized the phone
Front ports of PC chassis sometimes give too little power so try an usb port on back. try with other pc as it might be problem with your pc

Alright, so I tried different ports on my PC both front and back, no usb input sound or anything. I'm wondering if the USB C cable that comes in the box of the 6t just isn't a data cable? I have developer options enabled, adb debugging, and have the default USB mode set to MTP. Nothing still. I wonder why. Have you tried connecting your 6t with the included cable? Just to rule out if it IS a data cable or not. Thanks!

Tried some ports on the back that are part of my motherboard, same issue. No sound and no entry in device manager. No notification on my 6t either. The phone CHARGES, but nothing more.

Could you try using your included cable and report back? Thanks in advance man!
Is there a possibility to try on another computer? Just to rule out that the problem isn't in the computer itself...
I've just factory reset my 6T and plugged it into a USB 2 port on the front of my PC, using the red cable that came with the phone, and it immediately recognised it. You clearly have an issue but we can rule out it being a general issue.
just checking. you say it charges, that was the default setting on mine after i enabled usb debugging. i opened notifications on my phone and the was a small one saying phone charging, when i clicked on it i got an options page for usb preferences and then switched to file transfer. works fine now.

are you in fastboot mode on the phone? are you just running the phone within osygenOS?
I'm going to say damaged cable.
Try any other device that you can plug it into. If it still doesn't work it's the cable. If you change cable and still a problem I'd RMA the device maybe faulty port on phone. Device is too new to be playing games like this. Get a new one.
I just connected my, to windows 10 laptop after seeing this post. No driver installed, red cable that came with phone, USB 3 Port in the laptop. Nothing was needed to do for it to be recognized. Worked just like that.
Albeit I enabled USB debugging in developer option beforehand and changed the option to file transfer.
Just wanted to show the settings
