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?

Plug in the phone, uninstall the drivers from Device manager, then unplug, and replug.

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

does adb work?
i.e. adb devices
or is USB debugging turned off at this point
Also. The one with the exclamation mark. Right click and go to properties. What does it say in device status

hi, adb devices works. (will list my device when usb debugging is on)
with usb debugging off, under portable device, the device status says "This device cannot start. (Code 10)". thanks.

still looking for solutions. maybe i should try uninstalling the ADB driver, but the problem is that when i uninstall the device from the device manager I don't see the option "delete the driver software for this device", any help?

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.

[Q] How to see all folders

Hi, when I plug in my device I can only see two folders and not all the folders I have on it. How do I bring up the dialog "Allow computer x..." again? I think I messed that up. Thanks ^_^

I had the same problem. After a reboot all the folders were visible.

It might be a driver issue. If you haven't already installed the ADB drivers, do so by following this guide pulled from the Rooting sticky:
Jubakuba said:
Get the drivers:
Uninstall any previously attempted drivers if they don't work and move to the next.
[url="http://forum.xda-developers.com/showthread.php?t=1514942"]Option One:
Navigate to the "Device Manager" (Control Panel > Device Manager) in Windows and Select the android device. Open the properties and select the "Install Driver" option. Pick the driver with "Install from disk." Ignore any warnings about the driver not being signed properly.
PDAnet's drivers may work if the above options don't. Simply install PDAnet (after uninstalling any previous attempted driver installations) to get the drivers.
Click to expand...
Click to collapse
Even after all of that, it might not work. Use MTP (Settings>Storage>...>USB Computer Connection. Try turning USB debugging on or turning it off (Settings>Developer Options>USB debugging). Try switching which USB port on your computer you are plugged into (that one gets me every time I plug my phone into a new computer).
Hopefully that helps somewhat. Depending on what else you need to do with your phone, you don't necessarily need the ADB drivers to see the folders, but I find that those drivers + that guide to be the easiest to install and follow.

USB storage not showing up in windows

Anyone else with problems seeing the storage after plugging into PC? adb command works and device drivers installed. Found another forum where turning the usb from MTP to charging and back under developer options does the trick. I have a non stock ROM and seeing if fresh out of the box experiences the same thing.

I have the same issue and can't seem to figure out how to get it to work. My work around has been to use ES File Explorer and open Remote Manager.
Edit: I just plugged it in again to see what I can find. I turned off USB Debugging and Developer Options. Plugged in and pulled the notification bar down, there is an option to change USB Settings to Charging, Power Supply, File Transfers (this works), Photo Transfer and MIDI. Give it a go!

I am running to the exact same problem.
I have tried with USB Debugging off AND on, still no go. I think there's a problem with installing the drivers. Whenever I check the device manager, it still says the drivers weren't installed. I have tried installing the Google drivers. What do we do?!

Need to get the drivers to install first and foremost. Even with USB Debugging on, I'm still able to pull down and change from charge only. Those drivers are key. I had to restart my computer before it was able to take the install.

I'm able to get to the pulldown and change the setting from charging to MTP. Every time I do that, I get a window showing that I'm installing the drivers for Nexus 6P. Then it completes. I can do this over and over again. In the device manager, there's a little exclamation mark by the Nexus 6P and says these drivers weren't installed Code 28. I have exhausted Google to no avail!
Anyone find a solution to this?

You chose to install the drivers manually instead of having the system do it for you? Right click the yellow exclamation .. update drivers .. allow me to pick .. choose the download file location see what that gives you.

When I choose the location, I see a bunch of options. The most relevant ones are ADB Interface and Android Device. Under Android Device there are several more options such as Android Adapter Interface, Android Bootloader Interface, and the such; no mention of MTP.

So when you change the option in the phone from charging to file transfer, did you check the device manager to see if there any unknown device showing somewhere?

Changing it from charging to MTP shows a MTP device in Manager with a yellow exclamation mark next to it. When looking into the details, it says that no drivers are installed. When I try "Updating Drivers", it says "Windows failed to install drivers. Code 28" or something along those lines. Code 28 MEANS that Windows failed to install drivers.
Thanks for nothing Microsoft.

Nexus 6p Connection to PC Issue - This Helped!
I had similar problems with PC not recognising my Device. I found http://www.technobuzz.net/install-google-nexus-6p-usb-drivers/ which helped me solve my issues.
1. Downloaded and installed the Huawei Nexus 6p drivers. This installed a Huawei Task Manager which connection to pair was still not recognisable.
2. Deleted old drivers (acer, samsung, htc) from' Device Manager'. This actually helped PC recognise my device which showed up in the Device Manager>Other Devices>Nexus 6p, also in PC interface but once moved off charging to MTP, computer didnt recognise device.
3. Downloaded and installed the adb/fastboot installer. Followed instructions till step 10. My screen didn't show anything like Andoid ADB interface, it displayed MTP file install, which I installed. Just remember to refresh in My PC interface when changing over from charging to MTP, sometimes Nexus 6p will be hidden.
4. Uninstalled the Huawie Task Manager.
This has solved my problem with PC and Device connection. The instructions given are from what I can recall of the process I went through.
Credit to Sidharth Rathore from Technobuzz for this solution.
Hope this helps.
Later.
p.s. I have a windows 10 laptop if this helps.

I was having the same issue until I uninstalled some other debugging drivers I had installed. So I would recommend crawling through your installed apps for any other android usb drivers and uninstalling them if you still have this issue.

Working on mine right now. Found that USB 3.0 ports will not recognize device. Once plugged into a 2.0, it is recognized. Might help your issue

MTP connection, windows 10.

Hello all..
I'm havin' a lot of trouble getting windows to recognize my nexus 6p on my home pc. The ONLY way i can get it to work, is i when i restart my nexus before windows will recognize it, and if i unplug my device and plug it back in, windows dosn't recognize it again.. Nothing is happing, not on the phone nor in windows. (only charge, but nothing in swipe down and no windows sound or popup)
The funny thing is, on my laptop with windows 10, i can plug- and unplug 10 times in a row and i gets recognized every single time without me having to restart my device.
Why won't my home pc recognize it, without me havin to restart the device? I've tried on windows 7 and windows 10, same same. I've tried different drivers, guides and more, nothing seems to help.
I'm running stock MHC19I, with usb debug enable.
Sorry for my bad english, and thanks in advance.

It is the misconfigured drivers that might be causing this issue. Not something that you would have done intentionally. But there is a rather simple fix. To start, do you have Android SDK installed on your machine?

It's weird. Anyways, right now I wouldn't ask you to redo everything.
Right-click on 'Nexus 6P', and then on 'Update Device Software'. Select 'Browse my computer for driver software'. Now, go to the SDK installation > Extras > Google, and select the drivers folder. Once you have done that, click on Next, and the drivers will reinstall.
Reboot the computer and see if it worked.

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.

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.

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.

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.

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.
