Hi, for everyone who's still interested, apparently this works:
1. Open CMD as an Administrator
2. Type: net localgroup Administrators local service /add
3. Hit Enter.
4. Install drivers

[Q] Windows 7 fails to install MTP driver

I recieved my N4 yesterday.
When I try to connect it to my notebook (running Windows 7 Professional), the installation of the MTP driver fails. The error message says something like "driver could not be found". ADB however works without problems. (I allready debugged some apps on the phone.)
I tried installing the drivers from the toolkit, but it didn't work.
On my brothers netbook the MTP drivers were installed successfully. But I can't get it working on my notebook.
Can anyone help me?

Thanks for your help. I allready tried an other usb port. It did'nt work.
I wanted to avoid it but I reinstalled windows. Now it works. Thanks again.
Hmm, messed with this problem for ages yesterday, mtp installed fine in normal mode but refused when in 'usb debugging' mode
simple fix, find your wpdmtp.inf file in windows/inf
edit it like shown, look for the [Generic.NTx86] and [Generic.NTamd64] entries near the top of the file........
[Generic.NTx86]
%GenericMTP.DeviceDesc%=MTP, USB\MS_COMP_MTP
%GenericMTP.DeviceDesc%=MTP, USB\VID_18D1&PID_4EE2&MI_00
[Generic.NTamd64]
%GenericMTP.DeviceDesc%=MTP, USB\MS_COMP_MTP
%GenericMTP.DeviceDesc%=MTP, USB\VID_18D1&PID_4EE2&MI_00
...then update the driver in device manager, use automatic search
just make sure the 'VID_18D1&PID_4EE2&MI_00' matches your device id, check in device manager.. but i'm guessing all nexus 4 are the same.. usb debugging mode
I did a clean install of windows and that solved the issue for me. Thanksfor your help anyway.
I usually see what drivers do install, like adb or whatever, and then remove/uninstall them AND delete them
Then installed this pack
http://forum.xda-developers.com/showthread.php?t=1998650
then connect to a different USB port and try again with the new drivers
Also, some USB hubs can be under-powered and cause problems.

Just FYI, just got a Nexus 4 from T-Mobile yesterday and the device ID is slightly different:
VID_18D1&PID_4EE2&MI_01
01 at the end instead of 00

It doesn't ask. I plug in the phone, and Windows says it can't install the MTP driver.
If I go into Device Manager and find the phone (with the yellow triangle and !) and select Update Driver Software, then navigate to the i386 folder from the Universal Naked Driver (on an i5 system), it tells me that "The best driver for your device is already installed" or something similar.
Of course, if I uninstall the device from device manager (and presumably the bad MTP driver as well), it disappears, so I have nothing to point to to install the drivers.
Earlier today I reinstalled the drivers for my N4 on my work PC (Vista Business) and I had to reboot before it recognised the N4 as an MTP Device - prior to that it only saw it as an 'MTP Device'. Now it sees at 'Nexus 4'
I have a similar problem I have a kindle fire
I have install the ADB driver but am having extreme difficulties getting the MTP drivers to work
I have tried everything (every solution on Google)
and nothing works
I've tried the "Media Transfer Protocol Porting Kit"
I tried to get Microsoft help they gave me the run around and confused me even more
here is the conversation
Microsoft: "Thank you for that information
Nathaniel I was checking your product key and it is blocked that is why you can not connect these devices to your computer, you may be a victim of counterfeit software so in this case since it is an OEM computer which means that the manufacture of the computer installed Windows 7 on your computer I recommend you to contact the manufacture of your computer to see if they have an option in order to resolve this issue you are having."
me: when i contact them what do I ask for?
Microsoft: You need to ask for a new product key
me: I am confused what does this mean? that the manufacturer put windows 7 OS on here illegally? but all PC's come with windows OS so every PC in the world is suspect to counterfeiting
them: No, this could be because someone still some information of your computer and use the product key to try to activate Windows until the product key got blocked
No, the name is not involved in this case it is jut the product key
what do I do?
is there an alternative to MTP drivers?
Solved
Hi, i had the same problem described in previous posts and I managed to solve thanks to what is written by meangreenie.
In practice, in the windows\inf of my Windows 7 the file wpdmtp.inf was no longer present but there is only the "compiled" version (wpdmtp.pnf).
I retrieved the file from an earlier version founded in he folder Winsys and so the LG driver are installed without further problems.

You might be using the wrong driver (Android ADB) instead of the MTP driver. This happened to me the other day!
If you're in Debug Mode, you've already done the first step I was going to suggest.
Here's the second step that worked for me: Open Device Manager -> Click Android Device (top of my list) which exposes "Android Composite ADB Interface" -> Right click that device -> 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" -> Next
Mine installed the MTP driver and then the N4 opened normally.

That works for me with USB Debug ticked and in MTP Mode but not in PTP Mode (on CM10.2-nightly-20130817). I absolutely can't see my pics in no way... (I suppose this is a bug from Google to be fixed in further updates). ADB and FB are correctly working as tested with NexusRootToolkit 1.7.1 Drivers Test.
May it help to delete original DCIM folder and start from a new one??
edit: Shame on me... I forgot that I've formatted my SDcard, so I've no picture in DCIM folder.... Sorry! So I can say that McDougal trick totally worked for me!
try to check the device manager to check the missing drivers with ! mark
Maybe I'm not completely getting the problem, but just doing this worked fine for me:

Enable USB debbuging in your phone. Go to Settings -> about phone -> tap about 10 times on build number item until USB debbuging is unlocked.
Also, on your computer go to the device manager, look for your phone, if you find it, right click on it, then update Driver Software, browse computer, Let me pick from a list of device drivers on my computer, USB composite device

"LG Software" mode error + solution

I've had the following problem which I solved and now I'm wondering if anyone else found it, since I'm afraid it might point out to some hardware fault.
When selecting LG Software mode on the phone for connecting to your PC, Windows (in my case, 7 x64) attempts to install an MTP USB Device, but fails with Code 10: Device cannot start. At this point I (after many trial-and-error cycles) had to select Update Driver for that device in Device Manager, select Browse my computer for driver software > Let me pick from a list of drivers, and from the next screen, pick USB Composite Device instead of MTP USB Device. It installed right away and then 4 other USB devices popped up, which also were installed (using Windows Update). After this, LG PC Suite (and also LG Mobile Support Tool) detected the phone with no problems.
So, were any of you confronted with this?
Just wanted to say I had the same problems following your steps allowed me to get this to work. Thanked!
Thank you so much. This solved the problem.
I'm actually having this same issue. When I click "Show me a list of blah blah" it doesn't give me a USB Composite option. I only get two MTP options, and if I check "Show Compatible Hardware" it shows a bunch of drivers for MTP, WMP, and some other protocols. Any ideas?

yes, but unfortunately i don't have USB Composite Device as a selection on Windows 7 64bit. any other suggestions to get this stupid lg software installed?
After spending over 6 hours on this problem and installing a new windows, I finally found the culprit, it was Xposed Media Scanner, disabling it fixed the problem. Of course if you did not install this module before then the solution is not for you, maybe it will help someone reaching this page from Google.

[Q] USB Issues with Windows 8.1

put in a new SSD and got Windows 8.1, did a fresh install on a new hard-drive, everything's been working great, My nexus 4 has worked with with ADB./Fastboot and I've been able to transfer files to and from it in MTP mode. Been like that for about 4 days until about 3 hours ago, I had Windows Explorer crash, had to run Task Manager, end the process, and then manually restart explorer.exe My device was plugged in when this happened, and afterwards, I noticed that I could no longer see my Nexus 4 under the Devices & Drives section of "This Computer" (My Computer had a better ring to it lol) First I tried rebooting both my laptop and my Nexus 4, then I tried uninstalled the drivers, rebooting, re-installing, and then rebooting again. Did that like 4 times now, each time re-downloading the drivers, and doing an MD5 hash to create a Checksum, and checking them each time. Also to no avail. ADB shows my device serial number when i enter : ADB Devices, but says it's unauthorized, so if I try anything like: ADB Reboot Bootloader, it says Device is not authorized.
So ! I don't understand wtf is going on. Was working fine before. The drivers are up to date, I just flashed the Official OTA image, and was on the leaked image prior to that. Then earlier this evening I switched to the newest version of the Nexus 5 Port, and everything was still working fine, hadn't made any changes in a couple hours before this happened. When I install the drivers, It acts like it worked. Instead of saying "NEXUS 4" under Other Devices in my Device Manager, it says Composite ADB Interface under Android Devices and MTP under Portable Devices. Sometimes tho the MTP entry will still show the Yellow Exclamation Point. But goes away. Don't know whats up with that either.
Also, it wont let me install drivers unless I am in MTP mode, which Usually you can install them regardless (tho I never tried in Camera mode, I am just assuming about that one) Usually I install drivers without MTP or Camera modes checked, but now if I try it, it says that Windows Cant find the Drivers, even tho I am obviously browsing for them myself and selecting them. And just now I tried updating instead of re-installing them, and it keeps saying that Windows has determined they are the most up to date.
So I am out of I ideas. I even updated windows media player cause that's what fixed my issue on Day 1 of running Windows 8.1 when it wouldn't recognize it at all. So I don't know. Sorry for the long post but I wanted to make sure I got everything in there so hopefully someone can narrow down what the issue is. Cause I've been at it for 3 hours, haven't slept yet, my Nexus 5 gets here today, and I need to get this fixed before I sell it to my buddy. Its brand new, only 15 days old.*
Any thoughts ?*
First, connect your Nexus 4 and use Device Manager to uninstall both MTP and ADB devices, make sure to check the box to delete the driver files as well. Then uninstall any other usb or adb drivers for other Android devices.
Then disable USB Debugging on the phone and get MTP to work first, Windows should be able to install it automatically.
For ADB, Windows 8 will not allow to install unsigned driver. To install unsigned driver, reboot Windows 8 into Advanced startup and press F7 at the menu to disable driver signature (Google it if you don't know how). Although you could install Google USB driver which is signed I think, I recommend using Universal Naked Driver (link in sig.)
ADB Devices, but says it's unauthorized

You need to authorize it from your phone, when you connect your phone to the PC with USB Debugging turned on, a toast message on the phone will ask you to authorize the device.

ok I am gonna try that now. And as far as the part about my phone being unauthorized. I already knew about the notification that pops up, i was waiting for it to happen. Never did tho. Maybe it will happen after I do the rest of what you said. thanks, i will post my results in a min
no matter what i do, i cant get MTP working. When i uninstall the ADB entry in Device Manager it gives me the check-box option for removing drivers as well, but not on MTP. And now it wont even give me the option to uninstall, update, or anything at all, even tho I uninstalled it already so it should at least give me the option to install drivers. Even tho it's showing up in Device Manager as a Portable device, if I look in Printers and Devices, it shows up as unspecified device. Disabled USB Debugging, and all that. it says its working but it wont show up in My Computer>Devices and Drives still. For some reason ever once in awhile it will pop up with the Yellow Exclamation Point tho, only for a brief second tho. other then that, its shows it like it's running correctly. Also, nothing pops up saying that windows is installing drivers when i plug it in. Which in Win 7, XP, etc, it always did. Does this not happen in Windows 8.1 ?
Also, under Driver Details, which is the only option it lets me click on MTP, it says the drivers are from 2006 lol
Update - Just reinstalled the drivers for ADB and enabled USB Debugging, and everything is still saying its working even tho its not. But when I take my phone out of MTP mode it shows up in device manager under "Other Devices" as Nexus4, with a Yellow Exclamation, and it gives me the option to update drivers, so i tried, but it says Windows Can't find my driver. This is very frustrating.
Had this problem aswell, which was caused by the N version of Windows 8 versions.
These versions dont have Windows Media Player istalled, which is needed for MTP to work.
So to fix your problem you need to download that latest Windows Media Player (WMP) from microsoft and install that.
I dont have the N version, I have WMP installed, i mentioend your fix in the OP. Had to update it, and it worked. It was working fine for the last few days, then it stopped working suddenly
double post, sorry. dont know why that happened.
Vouch. Since I use win8.1 (no n version) Mtp doesnt work. I tried all known drivers, disabled driver signature and so on. The only working combination for me is Usb Debugging + PTP. Then I use file manager to cut the files. Airdroid would be an alternative as well.
update - SOLVED * Kind of.....I say kind of cause I still don't know what caused it but apparently Flashing to the Nexus 5 Port fixed the issue lol. I am assuming something pertaining to the way USB connectivity is controlled by Android got corrupted, and a fresh install was in order. Whatever it was, it worked and i am back in business. thanks to all those who attempted to help.

Cannot connect to PC as MTP device

Hi all,
I just got my OP2. My PC is running Windows 10 x64. I cannot see the OP2 as an MTP device. It only shows up as a CD drive with its driver installers.
Here are the stuff I have installed on my PC:
1. OP2 drivers
2. 15 seconds adb installer
3. Microsoft update KB3010081
I can only see the OP2 in device manager as an "MTP USB Device" under "Portable Devices" but it is in error. This still persists even if I enable USB debugging. I installed the update microsoft update above because it is said to fix the MTP driver problem but not in my case.
Any ideas?
Okay nevermind I got it solved thanks to this youtube video: "MTP device driver installation failed , error code 31 solution"
I can't post links yet so just search the keywords on YT. I tried a lot of methods I've read but none worked except this one. I'm just gonna leave this here in case someone faces similar problems.
EDIT: still not fixed. phone now shows up but I cannot see any folder/files

Phone not recognized in PC, shows nothing

Basically it just charges the device even when selected media transfer, nothing shows up.

Any help is greatly appreciated.

Try connecting your phone to another system.. sometimes the drivers get corrupted on the system. If the phone is detected on another system, then just search on the net to show hidden devices in devices manager, and delete the ghosted devices in the device manager on the system.
No none of the methods are working.
Removed all ghosted devices too. Shows unknown device below sdm636, both have error sign next to them.
The main issue is all phones in device manager show up under "portable devices" but mine is showing under "other devices".
It's not updating even when manually done.

My last thought would be to enable USB debugging through developer options and check again.. sometimes it works as it does change the connected path in the phone. If this doesn't work, maybe you should try warranty to replace it.
Just for your info, there are android apps like Airdroid which can transfer any content from a system to a phone in a matter of seconds through WiFi.

If Windows 10, you will find an error like " device descriptor request failed" device under USB in Device Manager. Just uninstall it and reconnect your phone. It should detect under "This PC".

No that's not it.
Mine is a completely different problem, it says " one of the installers cannot complete the installation at this time ".
No difference if I uninstall update or disable it's getting nowhere.
Had same problem! Was trying all the steps, but for me helped to switch to MIDI and then to MTP (in developer settings) - now it works. Try yourself.

Somewhat a similar case to mine.
Today I decided to unlock bl , flash twrp and root my M1.
Tried 3-4 methods , 3 PCs , manually installed drivers and wasted 4hrs but all got zero results. Everytime after clicking on "unlock.cmd" nothing happens. Just command window shows erase all devices ... something like that.
I am currently on latest build i.e. 311.
Any help is welcomed.

Download and Install Google USB Driver - https://developer.android.com/studio/run/win-usb
Disable, if already enabled, USB Debugging then re-enable it and try connecting it to your computer. Try switching modes (charging>photos>mtp) if your device doesn't get detected straight away.
Solved : This works for me !!!
This is on my Windows 7
Go to Device manager and "Show enable hidden device" under view menu.
I found a new device at the very top with strange name (forgot to note the name)
Uninstall it and then right click on any device and click on "scan for hardware changes" again (Make sure the phones is connected when scaning)
It reinstalled the device and got my phone working
Hope this helps someone..
I somehow solved this by installing both usb google driver and the asus driver one for windows. Didn't restart my computer or anything and when I reconnect my phone with usb debugging and ptp transfer, suddenly there's the permission with certificate something on my phone and I pressed yes and allow this computer, and voila! It shows up after I typed adb devices on the command prompt.
I am having the very same problem but I can transfer file connected of a portable media player, etc.
The problem comes when I try to connect my phone via USB debugging, it shows "No drivers found". Also when installing/reinstalling drivers using 15 seconds installer in the second next windows it's Shows Google Inc. drivers are installed.
OS on PC: Windows 7 32-bit
Phone: Stock (Out of the box and updated over OTA updates to latest).

@.hack//G.U. Could you please upload the Asus driver somewhere and share it? Since then Asus has removed whatever driver was there. Nothing like that now in the Downloads.
You need to install your phone's drivers in PC
You need to install your phone's drivers in PC in order to get recognised by your PC.
Try ADB driver which is time saver always.
