Nexus 4 not being recognized in windows 7 - need help

Hi,
Just got a Nexus 4, had a Galaxy S2 before. The problem is that I can't get it to be recognized in Windows 7 x64. Nothing really happens, I plug it, it starts to charge but nothing more, no icon appearing at device manager etc. Tried to install the drivers via nexus 4 toolkit and nothing changed, tried on another windows 7, a notebook and its the same. Changed the USB cable, no difference. Charging and nothing more.
I searched on internet and found similar issues but didn't find a solutions.
PS: Its a new phone, never unlocked or rooted.

Works here dude download latest android SDK and go to device manger on computer update drivers

Get Wug's toolkit. http://forum.xda-developers.com/showthread.php?t=2015469
Follow the directions for installing the drivers. Really follow them exactly.

Installed the toolkit, folowed the instructions but the problem still there. The problem is that when I connect the phone I don't get the "connect to usb" familiar sound but the charging starts. So is not that the drivers are wrong or bad, the problem is that is that the phone doesn't even shows as something in device manager.

Go to your phone settings.... then click on about phone....
then scroll down and hit the "build number 10 times" that will unlock the developer menu
then go back to "about phone" scroll down to the developer menu.
then check box for "usb debugging" and the computer will see the phone.

Had this problem too the first time i got my Nexus 4.
It frustrated me for the first couple of hours when i could'nt connect it to my pc, and no solution seems to work.
However, i found the solution. This was: Install the latest version of Windows Media Player.
This phone uses MTP, instead of mass storage, and thus needs WMP.

I have the latestes WMP version and anyway, I have a digital camera that works in MTP in this same PC.
This is becoming short of solutions and I beginning to think maybe its a nexus 4 hardware fault.

turn them both off and on again

I have this same problem and haven't found a solution yet!

I have this problem only when USB Debugging isn't turned on. I'm not sure what's wrong with it but by computer (running W8 Pro) won't see my phone until I turn on debugging. All drivers are installed but the only way I can copy files to/from my N4 is with debugging enabled.
Would love to see a solution come through and I'll continue looking for one myself to help us all out.
-Sent from that.... you know.... thing that sends these things-

Same issue.
I have tried over 5 computers running windows 7 and about 5 different usb cables.
I have tried having usb debugging checked, unchecked, MTP on/off and PTP on/off.
Still nothing.

Im having this problem too. I tried in 4 different pc's and a mac. My nexus 4 cant be detected. Its just charging. Weird thing is that no "Charging (USB)" on my lock screen just "Charging"

i had the same problem and read everysingle forum and finally found the working solution
Device Manager - right click device (Android ADB OR Nexus 4 ADB interface)
- Update Driver Software
- Browse my computer for driver software
- Let me pick from a list of device drivers on my computer
- then choose "MTP USB Device" OR "USB composite driver"
- Next
here you go instant discovery
make sure you are on MTP and USB debugging is on

[Q] Nexus 7 USB connectivity to Windows XP SP3

Guys, I know i am repeating again the question but despite reading 15-20 posts and uncountable articles, I am still not able to get my nexus 7 working with the Windows XP SP3.
1) To start with, I downloaded the google drivers from ASUS and the MTP Porting Kit from microsoft.When i plug in the device with USB Debugging on, Windows shows 3 new devices- NEXUS 7 & Android ADB Interface.. and ofcourse Windows XP can not find the drivers for any. So i open the device manager and it shows Nexus 7 under unidentified devices. I install the drivers for ADB interface (the ones i downloaded from Asus) and the device becomes ready to use. But there is no option to browse the device from my computer or portable devices. Then i switch the debugging on, and now there is a new device- MTP under unidentified devices. Then i install the MTP Porting Kit, but the MTP device still shows a problem with the driver.
2) The second part of the problem is that all this did not work and even my WMP11 does not recognise the Nexus 7.
The device is just connected and charging!!! What am i doing wrong here???

Try to delete the precompiled inf-file 'C:\WINDOWS\inf\wpdmtp.pnf', edit the 'C:\WINDOWS\inf\wpdmtp.inf' (see link in the post in the top...), open the XP device-manager, right-click in the yellow '!' and 'update driver'...

I had a lot of problems myself getting Windows XP to work with my Nexus 7 as well... eventually I discovered that installing the latest version of Windows Media Player fixed the problem.
I wrote up a post on this issue on another forum (Sorry, XDA - this was before I discovered you guys), back in December of last year.
Anyway, here is my original post...
http://www.nexus7nexus10.com/forum/nexus-7-help/2600-cannot-connect-pc-2.html#post36608
(Actually, this whole thread is worth reading.)
The only nuisance factor is having to remember to re-enable USB debugging (Titanium Backup needs USB debugging enabled, and complains if itsn't) AFTER I've run some MTP Windows XP related file backups (USB debugging needs to be disabled, or MTP won't work)...
....or at least that is my experience.
Hope this is of some use.

Hello guys,
I have the same issue on windows XP with Nexus 7. I tried everything what was suggested and nothing is working.
I have Windows XP SP3 with WMP11 and MTP porting kit installed as well. the device is recognized and driver is instaled fine. But it's not visible on "my computer" in MTP mode. I tried to turn on usb debugging and still device is invisible in windows explorer, the same is when usb debugging is turoned off.
When device is in PTP mode it appears in "my computer" and i'm able to browse it and see all pictures and photos.
How can i browse my device in MTP mode and copy files there? Please reply if anybody knows what to do to fix this issue.
Thank you.

Recently got a 2012 Nexus 7 from a retailer selling this model with updated Android at very attractive price, and initially able to connect to computer so promptly rooted the device with the Nexus Root Toolkit from Wugfresh Development (in this forum), afterwards had same problems with not being able to read / transfer files.
Tried every fix I could find in other threads, and although device manager saying that connected as 'ADB Device' with debugging on, or 'Google Nexus 7 ADB Device' with MTP on and debugging off, still stuck with no access.
Looking closer at the MTP configuration ('Google Nexus 7 ADB Device') under device manager noticed that details listed manufacturer as 'ClockWorkMod' , and eventually that this originated within a Windows\Inf file titled 'oem60'.
I cut and pasted the 'oem60' file to another directory (to keep it safe just in case this upset something else) then on reconnecting the Nexus 7 as MPT with debugging off, device manager found and installed the correct driver at last. Now able to see and transfer files to / from it.
Presumably could alter the relevant lines in the 'oem60' file, which aren't hard to find, and put it back to original directory, but my other devices also working fine so not done so as yet.

Nexus 4 cannot be recognized as MTP after root

I'm running Windows 7 64bit and followed the Ultimate guide to unlock and root my Nexus 4.
Everything went well but now it looks like that Windows won't recognize my phone as a device. When I plug in the phone, the auto-play window will pop out and recognize it as Nexus 4, but there is no other options. (Normally the auto-play will ask if open folder to view files or transfer photos). I can't see my phone in device manager either.
If I turn on the USB debugging mode, I can see it in device manager but still cannot see it in My Computer. Looks like Windows can't access the SD card at all.
I tried switching to the camera mode but the problem remained. Please help.

desperate bump. can anyone help?

Maybe it's a stupid advice, but have you tried change the USB port in PC?

thanks for your advice. the problem is that, without USB debugging mode on, I can't see Nexus 4 in Device manager, even though the Windows Auto-play will say Nexus 4 connected. (Nothing in My Computer either)
With USB debugging mode on, I uninstalled the driver and Windows would try installing the driver. Now it shows up as MTP device with an exclamation mark. I tried manually update the driver (direct it to the Google SDK folder and pick the android_windowsusb.inf) but it says it does not support x64. I don't think the 64 bit driver is digitally signed.

I think I had a similar problem as yours. If you deleted the drivers while on debugging mode and reconnected after and it's showing the exclamation mark of a unknown device, try restarting your computer and plugging your phone back in.

i did and it remains the same.
Is there anyway I can know all the files names of the drivers so that I can manually delete them from system folder? When I uninstalled it from the device manager, I don't see the option "Delete the driver software for this device".
I can still see it under "adb devices" list.

I think there are some conflicts in the drivers.
Now when I connect Nexus 4 (without USB debugging mode on), it will show up in device manager under Android Device.
With USB debugging, it will then show up under Portable Devices.
However, it's supposed to work the other way around. that is (no USB debugging --> portable device; with USB debugging --> Android Device).
How can i solve this?

Have you tried manually installing the drivers before plugging in the phone, vs letting windows choose the drivers it wants to install? One option you could try is installing PDA Net on your pc. It will install reliable drivers on your pc.

i also had this same problem after flashing my first custom rom on the n4, and i also run windows 7 Ultimate x64
here is the process i use for full clean installation of device
on phone
goto SETTINGS > STORAGE > (menu) USB Computer Connection
make sure Media Device (MTP) is checked
With USB Debugging On
On your PC go to device manager
there should be 2 devices (Android Phone > Android Composite ADB Interface & Portable Devices > Nexus 4) - this is on a fully working n4 so you might only have 1 of them
Right click on each of them and click uninstall
The popup box should have another check box to delete the driver also, if this is available check it then confirm (note mine only has the box for Android Phone > Android Composite ADB Interface, but if yours has it on both then check it on both)
your computer will now ask you to restart, dont do it yet
repeat previous step for the other device if you have 2 then reboot
upon rebooting it will automatically start reinstalling drivers
by expanding the selection you should see 2 devices
Nexus 4 - Successful - Ready To Use (this is your MTP connection)
Nexus 4 - Unsuccessful - No Driver Found (this is your ADB Connection)
at this point you should be able to access internal storage however ADB will not work
go back into device manager
you should now have
Portable Devices > Nexus 4
and Other Devices > Nexus 4 (with yellow exclamation mark)
right click on the Other Devices > Nexus 4 (with yellow exclamation mark)
hit Update Driver Software
click Browse my computer for driver software
click Let Me Pick Drom a List of Device Drivers On My Computer
double click Show All Devices
click Have Disk...
click Browse
navigate to the download directory for the google usb drivers (for me this was "C:\Program Files (x86)\Android\Android-SDK\Extras\Google\Usb_Driver")
double click on the android_winusb.inf file
click OK
double click "Android Composite ADB Interface"
it will then install the driver for ADB
you should now have full access to internal storage and ADB

thank you for your long and detailed reply.
this is what i wanted to do, but the problem is that when I uninstall them, I don't get to see the option "delete the driver software for this device". What should I? cuz every time I plug in Windosws just tries to automatically install the driver for me.

Have you tried toggling to ptp mode then back to mtp on your phone. It's odd indeed.
The fact that you can't remove the driver is because that is the mtp one which is built in to media player. Let me give this some more thought
EDIT: You said that with USB debugging disabled your device is listed under device manager as an android device
can you check and verify exactly what it is listed as? as it should be portable device

I have this same issue I'm trying to find a fix, that's how I found your thread. Alex gave very good info make sure you go back to his posts and hit his "Thanks" button, I did it on everyone one of his posts in this thread. I'm starting to think it's a hardware issue and not a software issue, I've never had this issue on any device. When I got it new running stock 4.2.2 MTP didn't work. ADB works and PTP works, just not MTP no matter what I try. I recommend you learn to use, ADB push and pull to move your files if you don't already know how to use it (To use ADB I need to check PTP for it to work and not MTP) you might need to do the same. I will keep you posted if I find a fix.

I'm just getting more and more confused with this.
If Adb works then you must have an Adb driver installed for the phone. However your also stating that you get no box for uninstall driver.
With USB debugging disabled you said that it appears as an android phone rather than a portable device. This should not be.
With debugging disabled what happens if you Try to uninstall in device manager

My theory still stands that you have updated the mtp driver with adb drivers. Hence why mtp doesn't work but ptp does.
The problem is getting to a position where you can uninstall the adb drivers from the mtp device and let it reinstall the proper drivers
Sent from my Nexus 4 using xda app-developers app

I plugged another Nexus 4 in, and all the drivers loaded perfectly. I then tried my Nexus 4 phone, and nothing happens. No mtp, no adb, no boot loader drivers. Its my phone. My next step is to find a zip file that I can flash via custom recovery, which will bring all the binaries and ROM back to stock. Anybody know where I can find this? I'll probably lose the custom recovery, but hopefully it will be fixed and I can flash the custom recovery again.

How to regain mtp access for usb file transfers

Many nexus 7 (and I believe nexus 5) users have had the annoying problem of losing the ability of their windows pc recognizing the nexus as a mtp device. In my case this happens every time I have to root the device. Something about installing the necessary adb drivers seems to mess up the ability of Windows 7 to install the correct driver for mtp access. Typically, the nexus will connect in ptp (camera) mode but not ptp. Updating the android phone driver just doesn't change anything. I tried all the recommended steps but nothing worked till now. Here is what worked.
After rooting, my Windows device manager showed only one entry related to the nexus 7. It was an entry for "android phone" and within it was an entry for "Google nexus ADB interface".
**there was NO entry for "portable devices" **
1. In device manager, with the nexus connected via usb cable, I clicked on the "Google nexus ADB interface" (inside android phone entry) and selected to update the driver, then selected "browse my computer for driver software", chose "c:\Windows" and - this is what is different - selected **let me pick.... **
2. The resulting options included 2 choices, but no mtp option, and I selected "Google nexus ADB interface"
3. When it installed, suddenly "portable devices" appeared in the Windows device manager with nexus 7 in it !! But with the yellow error symbol.
4. Next, I right clicked on the "portable devices /Nexus 7" entry and updated it as usual. Yellow error icon disappeared and now mtp works fine.
The important points are that
- standard 'update the driver' does not restore the mtp driver (perhaps because the correct Windows driver is in a different location and has an older date), but selecting one of the 2 offered choices in **let me pick.... ** within the c:\Windows\ directory worked to recreate the entry for "portable devices" and when that was updated, mtp connection was restored and I could copy and transfer files via usb cable!
Hope this helps someone else. Thank you Vyom for verifying this worked and refining my description to make it more precise.

For me turning off adb and reconnecting the cable fix the issue. Try it and report back.
Please ignore my spelling mistakes. English is not my native language.

Yes, but I now have both abd and mtp.

My rooted Nexus 7 (2012) previously had no problems connecting to my Windows 7 computer and I was able to transfer files via the USB without any problems. After installing Android 4.4, I am only able to get it to connect via the PTP option (camera files only). I downloaded the latest Nexus 7 driver from Asus' web site and tried the above step to no avail. After several hours of eye strain from perusing the forums, it's time to ask the experts. Thanks in advance

Something about installing the necessary adb drivers seems to mess up the ability of Windows 7 to install the correct driver for mtp access. Typically, the nexus will connect in ptp (camera) mode but not ptp. Updating the android phone driver just doesn't change anything. I tried all the recommended steps but nothing worked till now. Here is what worked.
After rooting, my Windows device manager showed only one entry related to the nexus 7. It was an entry for "android phone" and within it was an entry for "Google nexus ADB interface".
**there was NO entry for "portable devices" **
1. In device manager, with the nexus connected via usb cable, I clicked on the "Google nexus ADB interface" (inside android phone entry) and selected to update the driver, then selected "browse my computer for driver software", chose "c:\Windows" and - this is what is different - selected **let me pick.... **
2. The resulting options included 2 choices, but no mtp option, and I selected "Google nexus ADB interface"
3. When it installed, suddenly "portable devices" appeared in the Windows device manager with nexus 7 in it !! But with the yellow error symbol.
4. Next, I right clicked on the "portable devices /Nexus 7" entry and updated it as usual. Yellow error icon disappeared and now mtp works fine.
The important points are that
- standard 'update the driver' does not restore the mtp driver (perhaps because the correct Windows driver is in a different location and has an older date), but selecting one of the 2 offered choices in **let me pick.... ** within the c:\Windows\ directory worked to recreate the entry for "portable devices" and when that was updated, mtp connection was restored and I could copy and transfer files via usb cable!
Hope this helps someone else. Thank you Vyom for verifying this worked and refining my description to make it more precise.

I followed this advice, but didn't work for me. However, I then chose the 2nd option, "USB Composite Device", updated that and Voila! The "Unknown Device" with yellow warning still appeared, but I deleted that and all is good, thank you.

simple fix turn usb debbugging off
So your computer can install the driver for u

It worked!

Lots of thanks! It worked... I can now connect my rooted Nexus 7 under MTP mode!

My rooted Nexus 7 (2012) previously had no problems connecting to my Windows 7 computer and I was able to transfer files via the USB without any problems. After installing Android 4.4, I am only able to get it to connect via the PTP option (camera files only). I downloaded the latest Nexus 7 driver from Asus' web site and tried the above step to no avail. After several hours of eye strain from perusing the forums, it's time to ask the experts. Thanks in advance
EDIT: Finally got it to work after following the instructions on this thread: (Took several tries)

I've been trying to fix this issue for way too many damn hours. Thank you so much for coming back to your own post and putting in the solution. This has been driving me CRAZY. Happy holidays

[Q] ADB drivers not working

Hello. Im new to the Nexus 10. I downloaded skipsoft Android toolkit, installed adb drivers in the package and rooted the Nexus and installed recovery..it was easy using the toolkit. So the ADB drivers must have worked- at least in the environment it is used in to do these things. But these drivers dont work to transfer files between the nexus and the computer running winxp. I have USB debugging and PTP, have tried every other dirver package that has been mentioned on all available forums, have tried different usb ports, different cables etc. n my computer the device is recognised as a Nexus 10 but clicking on it gives a blank page, so cannot see the Nexux files. WTF this is driving me mad. Any ideas?

Re
Hi Ghosta,
Are you using a USB 3 port? as i have had many strange issues with these the ports. The issue is caused by one of the intel drivers cant remember exactly which way but there is no easy way to fix this. If this is your issues i would try and find if you have a USB 2.1 port you can use or the Esata ports on laptops tend to be usb 2.1 inside...even though they dont look like it haha
Hope this helps

What does Device Manager show? Device name, its Properties and exclamation mark?
You do know that if your device has a "password" then you must be logged in to see its contents.

Thanks for the replies and suggestions. All shows up OK in device manager, the device is not password protected, and the laptop has usb2 ports. I had another try today, after connecting the nexus it shows up in my computer as a camera, labelled nexus 10, with the camera icon. When I click on the icon it opens a special folder, must be a camera folder and the camera and scanner wizard starts. After a while it detects the photos on the nexus ( I have loaded a lot on it via USB otg using flash drive ), but thumbnails of the photos are not downloaded as I usually see when I connect a camera. The wizard downloads photos back to the computer, but each photo is about 18 kB instead of the 2 mb they originally were. So it appears a connection is happening, but a very strange one. I don't like to be beaten on problems like this one, but searching the net has not given me any answers, and I don't understand the android system well enough to know what to try next.

I think your device is working. If you connect it up as it now is and then go into Settings > Storage and tap the top RH corner menu you get the USB Computer Connection and select that and change it to MTP you should find it is now visible in My Computer or after auto install of the driver it will be visible. I'm brain dead - you said you had a PTP connection!

No PTP conection or MTP connection either. The Nexus also shows up in Device Manger under Imaging Devices when USB deugging is on, which is causing the camera and scanner wizard to start, although it doesnt work properly. When i disable it nothing happens at all. No idea where to go from here.

There is or was an issue with XP see http://forum.xda-developers.com/showthread.php?t=2305943

Thanks for the suggestion, I had already tried that but I did it again just to make sure. It did not work for me.

Have you tried following the driver install guide from Wug's toolkit? I've never used Skipsoft's but if it doesn't have you delete old drivers properly it's possible there's some old or corrupted driver sticking around from all the installs you've done. If you follow Wug's guide exactly you should end up with the only the correct drivers installed. Also, what ROM and kernel are you using? It's possible the issue is there.

I used a program called usbdeview to uninstall every USB driver with an "android" or "adb" description which should have cleaned up my drivers? Then after reinstalling drivers I tried again no difference. I ran android-tools and can push and pull files to and from the computer and nexus, (from command line) so I believe I have eliminated hardware problems and software problems on the nexus. This leaves the computer, which works perfectly with my other android devices running 4.1.1.

Just in case this helps. In usbdeview I have 5 nexus 10 entries. They all have the vendor id of Google 18d1 and a unique Product ID . Which driver connects is related to the device settings:
PID Device settings
4ee1 MTP
4ee2 MTP + USB debugging
4ee5 PTP
4ee6 PTP + USB debugging
d002 USB debugging
With the device connected I can change settings and see the change in connected driver in USBDeview.

This info does provide me with some way forward. With USB , when connected ptp I have a nexus 10 USB composite device and a nexus 10 digital still camera connected with the green light in USB deview, and also a blank device name, connected, description android composite device with a purple light. I'm guessing purple means not working. But changing drivers does nothing to change the purple light. Switching to mpt gives an additional blank name Google nexus adb interface also with purple light shown as connected. All connected devices show vendor 18d1. Drivers tried 1) clockworkmod (supplied with skipsoft); 2) naked drivers 3) Google drivers. Any clues what to try next?

2 things to check. I just tried running usbdeview from Wug's toolkit. It was v2.0 and wasn't the same as the version I have installed v2.3 - and there have been a significant number of changes. If you have XP pro x64 then you must use the x64 version of usbdeview - again I think Wug's may only ship with 32 bit usbdeview http://www.nirsoft.net/utils/usb_devices_view.html You will also find an explanation of the coloured radio buttons.
If you find you need to update usbdeview then I would suggest you uninstall the device drivers (instructions in Wug's toolkit?) then new drivers from http://developer.android.com/sdk/win-usb.html#top and follow the linked install instructions.

I gave up completely on this, and connect via wifi using ES file explorer. I bought my wife a new tablet an Acer Aconia A1-830 and it has the same problems, impossible to connect via ADB, with exactly the same symptoms. Yet our phones connect via ADB without a problem, but both are Androild 4.1 or earlier and the tablets 4.2 or younger. Obviously an Android generated problem that arose when 4.2 was released and on which has no fix.
