Cannot transfer files with MTP / Device not viewable in Windows Explorer

When I connect my Nexus 7 to my Windows XP (SP3) PC via USB, it's obvious the computer recognizes it and it tries to install ADB drivers. Whether I choose to install those drivers or not, I still can't locate my device in the Windows Explorer Tree. I checked Disk Management for the hell of it and nothing but my PC's harddrives were there. There's an attempt to install drivers for "MTP" but that fails and I'm pretty sure that's the cause; however, I'm unable to replicate it, even as I uninstall/reinstall applicable drivers from the device manager the MTP failure never happens anymore. I did some googling and found a thread with someone who had a similiar experience. In turn, I downloaded https://www.box.com/s/2c25e8bc42ecce400afd to try a different set of drivers. Same problem. Driver install is fine for ADB, but still unable to see my device in Windows Explorer. I'm able to successfully connect the device to the PC with PTP for the camera. I can access DCIM and cache which can serve as a work around, but I'm hoping you can provide any ideas you might have. Thank you!
edit - ***resolution***: Ok, I figured it out...I had to disable USB debugging. I don't know if this helped either, but I installed these drivers as an alternative to the drivers that were originally installed: https://www.box.com/s/2c25e8bc42ecce400afd
While connected to PC, I switched to PTP mode because I was about to give up and just use that
I then disabled usb debugging and switched back to MTP at which point the drivers successfully installed and I could now view my device in Windows Explorer. I also believe downloading the drivers in the link above helped since the first crack I took at this was unsuccessful with existing drivers.

install pdanet on pc and it will install drivers for u so it will be recognized

Been battling with this on my XP machine since yesterday. I couldn't even get debugging to work until I installed NakedDriver. And even still, there seems to be no way to get MTP to work without turning debugging off. On my Win7 machine everything worked perfectly, both ADB and MTP, right out of the box. I have the Galaxy Nexus drivers installed on both machines (which I've read are compatible with the N7). I also have the latest version of Windows Media Player (I've read that some older versions have issues with MTP). Is anyone else able to run ADB and MTP on XP?
*edit*
A: Does PDAnet let you use MTP and ADB simultaneously? Because I really don't want to install it if I don't have to. I got rid of it ages ago (too many things starting up at boot time).
B: I have a Galaxy Nexus also, and I have no issues on the XP box.

I wouldn't bother with MTP, it's not always showing the contents of the internal storage properly when viewed in Windows Explorer.
Earlier today when I was trying to set up a backup profile for it, it didn't copy all the files off. On closer inspection I found folders like TitaniumBackup to be completely empty, which is not true according to ES File Explorer on the tablet.
I tried connecting MTP again, with USB Debugging on and off but this made no difference. Also I'm only seeing the Notifications folder instead of 36 folders on the internal storage now, really random how it's working.

Same here. No change with the Asus drivers. Still can't use MTP when ADB is turned on.

poo. how do I transfer my audiobooks to this stupid device without working drivers?

1. Please disconnect Nexus7
2. Remove drivers on PC.
3. Toggle ON : Settings->Wireless&Networkings->More->NFC.
4. Re-connect device
Good luck !

1. Uncheck MTP, check the one next to it (Camera)
2. Unplug USB
3. Turn off USB Debugging (Uncheck it)
4. Plug in USB
5. Should say connected as camera, then a new window will pop-up allowing you to see your files.
Tell me if it works!

im having trouble too, is there any way to make the device to be recognised as a flash drive?

Same observation here (a few months later) on stock Android 4.1.1 rooted.
It seems that new files in the internal memory remain invisible for a long time, but so far they have become visible eventually, sometimes a day or two later. I have no clue what could possibly cause this, and I have not found any trick or workaround that makes them visible, not even rebooting. Any hint is welcome.

Didn't work. Just shows up as a camera with the limited folder access one would expect.

Workaround
I now use the following workaround.
Install SDrescan from Google Play.
Run it.
If you already had your phone connected to a computer as a media device (MTP) and are watching the contents of your SD card or internal memory in Windows Explorer, press F5 to refresh your view. If not, connect it now.
I'd be curious whether this works for you as well. If it does, press the THANKS button below.

Same issue with an old ibm x40 udated to windows xp pro SP3.
I've installed mtp driver, without success
I've "tried" to install asus driver, without success
I've tried to do as above with the help of the nexus toolkit, without success.
Everytime, the laptop recognize the device as android ADB interface.
Someone could help me?
Thank you in advance

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

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.

Windows 10 Not Finding My Phone

Hello, I am having a rather strange problem. My PC did the dreaded auto upgrade to windows 10 the other day and I also got a new Nexus 6P. It seems my computer won't recognize my phone, at all, when I plug it in via USB. It's not even showing up in the device manager as a problem, it's like nothing happens at all.
I have
- downloaded and installed the latest google usb driver (right click install)
- downloaded the latest mtp drivers
- downloaded official nexus package from Huawei
- installed ADB and android SDK and also reinstalled the drivers from the SDK manager.
- downloaded some update for windows media player as someone mentioned that could be the problem
- tried different cables
- tried different ports (usb 3 too)
I am really at a loss. My work computer works just fine with it so I know the phone and the cable are okay and other things work on those ports on my home computer. By the way the computer is Windows 10 pro - 64bit

Have you installed Google USB Driver for nexus 6p? If not, download Google USB Driver, extract it and save it in your any name folder that you can locate it later, plug n6p in your pc or laptop and it should pop up with USB option to select either file transfer or picture transfer, click one of them, Windows should be able to find n6p driver, if not, go to setting on your pc, device manager, then look at highlighted USB of your nexus 6p whether it is properly installed, if not, then install it by finding the driver that you extracted in that specific folder... Hoping this works for you.

Thanks for the response, but yea I already got the new usb drivers and installed them via right click install. The thing is though that in device manager the phone doesnt show up, at all, not even as a problem device. Its like its not there. The phone shows that its charging, but it doesn't recognize that its plugged into a usb port. Im really unsure what to do about this.

Did you install x64 driver from Google USB Driver? Check to see to make sure your USB android debugging is checked. It is kind of odd, try to reboot your pc and nexus 6p, then plug your phone in different USB port if your pc has extra USB port..

Ah I see what you are referring to. Well, here is the thing, how do I install those drivers? Remember I cant find it device manager to update the drivers. The only way I could find to install them was to right click the android_winusb.inf file and choose install. It said it installed okay, but of course its not working. Any idea?

By the way, I also have usb debugging on and usb configuration WAS set to MTP, but I just changed it to try the different variations, but now its stuck on charging and wont change to MTP, but I think its because the phone isnt being recognized by the computer because this morning at the office I was able to change the usb type to mtp and the others, but that computer recognized the phone...

By the way, if your Android debugging on or check? Just turn "developer options" on your phone and then check Android Debugging. To install x64 USB Driver, on your pc, control panel, device Manager, look for phone USB Driver to see it has some kind of yellow triangle, if so update x64 driver from your extracted folder...

WAIT! I got it... Wow I would of never thought this, but apprently my Wacom was the problem. As soon as I unplogged my wacom tablet the phone picked right up... Strange... Anyways, case closed... freaking conflicts!

Okay hold on, still having problems. Well, now the computer dings when I plug it in, but it still doesnt show up. However when I change the phone usb to PTP the phone becomes visible on the pc in windows explorer (but still not in device manager) and when I put it to MTP it disconnects and I cant see it in windows explorer anymore, and still cant find it in device manager... Ugh...

Okay sorry for all the messages, but i did get the MTP working. I had to uninstall the reinstall the drivers a couple times... very strange, but whatever its working... yay!

Did you figure out the problem? I'm having the exact same problem with mine and with USB mode not switching from Charging and the PC not even recognizing a USB device was plugged in.

I found using a different cable solved my problem. Don't really know why cause the first one I used seemed fine and worked to charge it, but by using a different one, Win 10 recognized it and got me in the game.

Drivers no longer working

trying to get some help for my ZE551ML 4gb - unrooted and with the latest update
I have never had an issue plugging my phone into my pc and transferring files. I bought my daughter a BLU R1HD and that wont wont show up on any pc when plugged into USB...yes dev and debug is enabled.....installed a bunch of different drivers to try to get that phone to work and it wont....
but worse is now my phone wont show up.
I went to the main thread here and located drivers and installed, and nothing....went to asus support and dl drivers and nothing...
does anyone know why or how i can get the drivers installed on my W10 PC so I can plug phone into usb and transfer files?

In the pc's device manager, is the device listed there? And is there a yellow mark on the device name? Maybe the drivers didn't install properly, you can right click on the device and click update driver, then choose automatically, you must be connect to the internet for it to find the required driver and install automatically.

I had same issue. Makw sure phone is not. Plugged into the pc. Load up windows into safe mode with networking. Once there open device manager. From the pulldown menu choose show hidden devices then find the Asus drivers and uninstall and if available tick the box that says delete the driver.. reboot, reinstall.... Done.
This will work for most usb devices that are having issues.

sadly this did not work. I grabbed the drivers from the ZF2 resource thread here at XDA
https://software.intel.com/en-us/android/articles/intel-usb-driver-for-android-devices
for the BLU R1HD I was told to install these
https://androidmtk.com/download-mtk-usb-all-drivers
whih i did and also uninstalled and resinstalled along with the intel drivers.
I did exactly as explained above and the device will not show up.
I have the Z00AD -- ZE551ML -- 4GB/2.3GHz 64gb version running Stock OS with NO ROOT - an its up to date (v 40.194)
I attached screen shot to show what I have going on - thanks

come on

Are you using the same cord for both phones with the computer? If so, try a different cord

Reboot the pc with the "disable driver signature verification" option and then reinstall the drivers.

This may or may not have some relevance to your problem. Try downloading a program called USB Device Viewer, run it as an administrator and uninstall all the phone drivers that are listed. Reboot your computer, plug your ZE551ML in and let it install the drivers. Hope this is of some help.

i finally fixed this bs problem. simply a matter of device manager >>>> portable devices >>>>> right click >>> update drive>>> browse my computer >>> Let me pick>>>

Phone not recognized in PC, shows nothing

Basically it just charges the device even when selected media transfer, nothing shows up.
Tried different USB cables, updating drivers, restarting nothing is working.
Device manager has a error symbol next to the driver SDM636, updating the driver however fails.
Any help is greatly appreciated.

if you are running windows 7 and up right click and click run as admin.
say yes to all the prompts.
if you are running 64bit windows you will get security error when installing device drivers just check always install and click install.
once it installs connect phone to pc and select mtp mode and see if it works.

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.

USB debugging didn't work as well.
AirDroid and share it for PC are annoying.

1) Download drivers at ASUS Website
2) Right click (your device) and update drivers in Device Manager
3) That's it

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".
Worked for me this way.

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.
