[Q] ADB works, but no MTP/PTP functionality

So I got my Nexus 7 2013 to work perfectly on my laptop, which runs Windows 7 x64. However, on my desktop, which also runs Win7 x64, I only have the ADB working correctly for the N7. As I recall, sometimes there is a device under Device Manager called "D:/", which is non-descriptive, but seems like the closest thing to the N7. I have tried to update this mysterious device's drivers by pointing to Google's USB drivers and the OEM drivers, but neither was accepted. There are also no devices with missing drivers listed in Device Manager.
At this point, I am not sure how to proceed. Is there a precise way identify under what device name/category the N7 shows up in Device Manager? Please advise. :fingers-crossed:

See if this helps:

Make sure USB Debugging is disabled, device is plugged in, and go to device manager in windows. Then right click on nexus 7 or android adb device, or any similar name. Then after uninstalling everything, unplug device and replug it in. Let windows get the drivers, and MTP should work!

Deleted everything related to google and nexus. Still installs as adb device but doesnt show as nexus 7 device! Wug fresh has this program in its tool kit

It might sound dumb, but I was literally just having this issue. But apparently certan roms or kernel disable MTP mode when they are installed. i reinstall every driver just now. My fix was as easy as going to Settings > Storage > Menu Button Top right > Enable MTP box.

Going to try a custom rom see if that works!

I have tried a number of the suggestions in this thread, including the deletion of all my google/adb/nexus (and samsung) drivers. None of these steps resolved my problem. However, at the end of the day, I can still use both ADB and MTP, just not at the same time. So it's not a big deal. I think I will mess around with Tasker and/or get a widget for turning ADB on/off.

Are you ale to get a nexus 7 device to show so you can access internal storage? I can only access camera storage.

Are you running stock?
If so, do you have USB debugging turned on?
If you have USB debugging turned on, the USB IDs change and it might not (depending on what you have previously installed) recognize the MTP device anymore.
If you turn off USB debugging, it should recognize MTP.
Now if you are on a custom ROM, there might be some issues on the ROM side causing the MTP problem. Try going back to stock and see if it works.
If you are on stock and have the case where MTP only works with USB debugging disabled, then you can try this driver inf I put together to address that.

[Issue] Nexus 7 2013 Cm installed ADB & USB Debug problem

Hello, as topic title, I have some issues with my nexus 7 2013 wifi model.
I installed official cyanogenmod 10.2. I would like to restore factory image, but i have some serious issues with adb drivers while usb debug is on.
I installed official google adb drivers, drivers from nexus root toolkit (not all toghether), but when i connect my nexus 7 to my pc (running windows 8 64 pro) there is no way to make him recognize my nexus, and all adb commands fail.
If I disable usb debugging and activate mtp, my pc recognizes the nexus 7, but still can't see the nexus itself in 'my computer'.
i need some help please.

You only need fastboot to flash the stock system images.

that does not completely solve my problem

Restore the stock ROM to see if USB Debugging and ADB is working correctly.

Are you saying your issue is you want adb and mtp to work at the same time and you have them working individually or are you saying you want to restore to factory images? If the latter, the previous poster already gave you the info you need.
Just boot into bootloader using Power Down, then press/hold Power+VolDown

MTP and driver problems after attempting Wugfresh nrk

EDIT:
So I got it rooted, but MTP still won't work on my laptop, but works on my friends laptop What drivers does the first method install? I thought about upgrading them to official drivers. But when I tried to do that, it says I'm already running the latest drivers... Should I uninstall them and try to manually re-install these?

See if the following method fix your device, anyway it fixed mine, btw mine was running cm10.2
1) Go to system settings--->>storage
2) Choose USB computer connection on the upper-right corner
3) Have the MTP option checked.
4) Try connecting your device to the computer usb port again.

Tried that on PA, no luck
Sent from my GT-I9100 using xda app-developers app

No one? Has anyone had any success with cm10.2 compared to stock based roms like PA?

me neither, can't even install the adb driver probably, although i've tried every way the nrt or nexus toolkit told me. T_T
with/without usb debugging, with/without mtp connection, using different usb ports, still no luck. Last thing i haven't tried is to connect n7 to another computer

This fixed it for me: http://forum.xda-developers.com/showthread.php?t=2390296

[Q] My computer not recognizing MTP AT ALL

Hey guys. I been here for like 4 hours just dabbling with everything. And cannot seem to find any solution to this...
I have uninstall all drivers and restarted like ten times now doing the same process over and over, cleaning up each file carefully of the nexus or any android device.
My problem is when i plug in my nexus 7 2nd gen, it seems to not even detect squat.
I have usb debug enabled
my MTP is on
( if i switch to PTP i can access the folder)
Ive done fresh start on everything i even look through device and try changing the option to MTP and STILL DOES not work
I don't even see my nexus 7 in my HDD external or anything, nothing pops up but an ADB success driver, and when i changed it to MTP a MTP success driver with STILL no luck....
I just bought it today and it worked fine earlier, now when i root it and stuff it seems to be glitchy with my MTP
I even factory reset everything i couldn't access my ADB
any help would be appreciated

Someone said that manually updating the adb usb driver in devices should show you a choice, choose mtp. It should then sort itself out properly.

On your Nexus, open "settings", click on "Storage", click on options(3 vertical dots on the top right corner), click on "USB PC Connection", now check MTP option.
Try connecting to your PC (or Mac) now. I didn't have to do that on a stock build, but for some reason I had to do it on a couple of custom roms. Hope it helps ya out...

Try enabling USB debugging. I know it sounds odd but its helped me with my devices.

do this only if you can see PTP on PC
On PC check device manger, on Android if there is ADB driver - uninstall it
On N7 set to MTP, debug off and reboot with N7 USB cable connected to PC
It should re-install the ABD drivers on PC before N7 fully boots up
You will be back in action.

Actually for me, it's the opposite. If usb debugging is on I can't access the device to view files. Try disabling it?

yea thanks though everyone I got it to work. I had my old nexus and new drivers mixing up my ports for some reason not being able to access it at all

My Nexus 2013 32GB 3G is not detected properly on PC, help!

Hello gentlemen,
i got the tablet for three days and all was fine.
Yesterday i installed unofficial CM 10.2 build and since then when i connect tablet to PC,
my tablet is detected as Nexus 7 with exclamation or as deb also with exclamation,
I tried to install nexus 7 usb driver, but it didnt find any device to which it could install the driver.
USB Debugging is enabled, if i disable it, nothing is detected.
What are my options now? can it be solved?
Everything else is fine.

No you aren't screwed, you really got to want it to break it. Just so I am clear then it won't show up as an external hard drive or anything unless you do a peer to peer setup? Also are you running the newest nightly of CM?
"I had to turn off USB debugging, delete the ADB drivers in Device Manager, then reboot the device while it’s still plugged in. Windows recognized the device as an MTP device & installed the drivers before it even fully booted."
Found this well reading on it not connecting to the pc. Simple enough to try out.

Yes sir, I can only see it as PTP or MTP, nothing else.

Should MTP be enabled when rebooting the device?
What i should achieve by doing this?
EDIT.: after restart of device it's trying to install AOSP on deb, unsuccessfully.

i thought that MTP is the only option to connect it to the pc because its sdcard is emulated on the same partition? my galaxy nexus and nexus 7 can only do MTP too, unless in recovery where i mount it somewhere along the lines of mount as usb storage?

You could be right, i don't know, i copied custom rom immediately after i got nexus, so i didn't really watched how PC see the tablet.
Anyway i successfully flashed back original firmware 4.3.1 and after reboot suddenly Nexus 7 is recognized correctly
and it automatically install driver from folder where i got usb driver from google. So .. i will take a few days pause before i flash custom rom again
Thank you all for helping me in this.
Cheers
