[Q] after installing android SDK and rooting Nexus File transfer stops working

I've never had a problem with android file transfer up till I rooted today. My wife has a stock Nexus 7 and I can plug her Nexus into my computer and the file transfer app will start. I have usb debugging turned on and the usb connection on my tablet is set to Media device.
Now as I'm typing this my Nexus has been connect to my mac for about an hour. I just went to the USB settings to make sure I had Media device selected and the file transfer window popped up out of nowhere. I killed it and tried again and it won't come up. Maybe in an hour or so if it does the same thing.
Any ideas as to what's going on? Very strange behavior.

Disable USB debugging.
Unplug/plug in your nexus.
The USB IDs change for some reason when you have USB debugging turned on and the MTP device isn't recognized as such. PTP (camera) mode continues to work for both cases though.

Thanks for the suggestion but It still fails. I disabled debugging and still can't connect. Switching USB modes didn't help either.

If that doesn't work uninstall the adb driver & then plug your tablet back in so it will reinstall

My next suggestion would to reboot the tablet with USB debugging turned off.
If that doesn't work, my next suggestion would be to delete the existing drivers and force reinstall.
All with USB debugging turned off.

Make sure after you plug in your device you're looking at your tab and click OK on the pop up........

Thanks for all the suggestions. It's working now. I was just about ready to delete the driver and the tablet started to be recognized consistently. I was in the settings screen and toggled debugging on and off while plugging in the tablet. I noticed the info bar at the top alternating between showing "debugging" and "media device" and I selected each one a couple of times when they came up. I think that it finally worked through the ID confusion that was mentions. I'll follow the the rest of the instructions if the problem comes back.
Thanks again.

It's acting up again so I'm going to try deleting the drivers. I thought I knew what to do but I can't find any information. What's the procedure to delete the driver? I'm running os x lion

I've tried every suggestion in all of these threads so far & nothing worked. Even after I deleted the ADB drivers, windows 7 would automatically reinstall them. When I tried to update the drivers, win7 said they already had the best drivers (ADB).
Here's what worked for me:
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.

I'm not sure how I finally resolved the problem on my mac. I toggled debugging on and off and rebooted a couple of times. That may have done it. I also ran the adb script in the SDK platform-tools folder. I don't know what that script does exactly but possibly it reinitialized the driver and ID.
Anyway, hopefully these workflows will work for others.

Rooted my nexus 7 (2012) last night and struggling with my laptop not recognizing it. This thread solved it!
Delete the ADB on my window, toggle off debugging and restart the nexus 7 with usb connected to laptop. works like a charm.
Thank you!

Guys, my N4 got this problem too.. until just a few minute ago
I read somewhere ini goge groups (i think N5 group), and found explanation that we can change ADB or MTP "mode" on device manager. On "Androoid ADB Device" right click and select "Update Driver Software". Click "Browse My Computer for Driver Software" and then "Let me pick from blablabla...." And then select MTP USB Device, "next" and my N4 detected on Windows Explorer.
Hope it will be usefull for you guys.

[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

[Q] Can't update Drivers

Hey guys,
I've been wary to flash the ROM of my Nexus 7, as it actually boots into the normal OS and does everything fine.
The basic problem is that I can't transfer anything to and from the device over USB. USB debugging is on and I have tried PTP and MTP.
One of the solutions I have been looking at is bad drivers on Windows' part, and that is where I am currently blocked. If USB debugging is off, Windows refuses to acknowledge my tablet's existence. If debugging is on, some drivers from Microsoft automatically install and the tablet is labeled as "unknown device".
My USB controller is up to date with the correct drivers provided by ASUS for my motherboard (ASUS Z87-A). I recently re-installed Windows 7 to put it on a larger SSD, and with this same motherboard, it now does not detect correctly.
If I try to uninstall the "unkown device" it simply disappears until I unplug and replug in the tablet. If I try to manually direct it to the correct drivers, it tells me that the USB drivers are incompatible with my device. The USB drivers are the ones downloaded directly from Google.
I can still access the fastloader.
If you need more information, just let me know.

When you first got the device, did you go straight into fastboot without booting it and plugging it in while in Android? Does that question even make sense?

Use this as a possible quick-fix (not all mode combinations will work right): http://download.clockworkmod.com/test/UniversalAdbDriverSetup6.msi, then reboot.

That would have been roughly a year ago. I believe I did boot straight into the OS.

To the first quick-fix, the ADB drivers are installed, but they are not the drivers that are utilized when the Nexus 7 is plugged in. Like I said, it instantly installs some generic Microsoft drivers, and refuses to recognize the ABD drivers are compatible for the device.
As such I can't even begin with option 2.

With the device plugged in, go into device manager and find the device, uninstall that device, and make sure you check the box to uninstall the drivers from the system, then leaving the N7 plugged in to the PC, reboot the N7, as it comes up it should redetect, it's important to leave the device plugged in while it is rebooting.

You may want to make sure you are not using a hub or USB 3.0 port for this btw.
Put the device into in MTP mode with debugging on, unplug the device, then download these, unzip them somewhere, right click on the unknown device associated with your Nexux 7, click Update driver software, click "Browse my computer", navigate to where you saved the unzipped contents, and select usb_driver folder, let it do its thing, reboot your PC. Plug the device back in, preferably into a different USB port then what you have been using, it should then show up as a Google ADB driver (or similar), you can test it with the command: adb devices see if that works, if not, leave the device plugged in, and reboot the device.
Let me know if that works or not, and I will continue in a new post.

Ok, plugged directly into a USB 2.0 port at the back of my motherboard. Recognized as Unknown Device when plugged in, disappears completely when unplugged.
So, here's exactly what I did: Plugged in device -> clicked on "Update Driver software" -> unplugged device -> Browse my computer for driver software -> directed to correct location -> replies: "The best driver software for your device is already installed", and it is not using the ADB drivers.
Going into "Driver Details" tells me that there are no drivers that have been installed.

Don't unplug the device, do like this, put it in MTP/debug on, leave it plugged in, "Update Driver software" -> Browse my computer for driver software -> direct to correct location.
I know my method works, I've done it to that laptop, my htpc, and my gaming rig flawlessly.
You may have to use a tool to remove all instances of those drivers and reboot, Wugs toolkit has the app, let me see if I can find the direct download for the app or you can just download and install Wugs Toolkit.
Here is the app, but I'd still recommend you install Wugs NRT, as the kit has a walk-through telling you which device IDs to look for to remove. Here is the actual tool wugs uses: http://www.nirsoft.net/utils/usb_devices_view.html, but again, unless you know which ones to remove, you're better off using Wugs tool kit device drivers walkthrough built into NRT.

Well, NRT is precisely where I started this whole thing.
Here is a picture detailing where the Nexus 7 is connected, and for reference, ALL the USB ports on my case, be it at the front or from the motherboard, are controlled by a hub: imgur.com/pP5ZbMv
Every other device's location is described as "Location 0" except for the Nexus 7 when it's connected.
Unfortunately at this point I'm probably just going to use Dropbox to transfer files when I need to.

I guess something is trashed in your system, maybe using a previous motherboard driver would work, dunno, sorry it didn't work out.

No problem, maybe you'll work on it again and you'll figure it out. Also, you can use airdroid for transfer of files, I hear it works really well.

Device not detected.

Ok so I'm trying to flash L. All of my drivers are updated, I downloaded them again and installed just to be sure, but when I have my Nexus plugged in it still isn't detected, and yes USB debugging is on. I tried adb reboot bootloader and nothing, then I manually went into the bootloader and typed the flash-all command and it stayed stuck on waiting for device. Very frustrating, any help is appreciated.

Try changing to PTP.
FWIW, I solved my driver issue this way. And mine works with ptp, mtp, debugging on or off.
You can also try using Koushs drivers, but it only is a half-measure fix.
Also sometimes you have to revoke usb auths, and unlock the device and look for the key fingerprint prompt when you first plug it into usb, and reaccept it.

Didn't work, followed your steps in the other thread. I guess I'll just have to wait until a flashable zip for L :/
edit- And btw I tried it on both of my hard drives, one with windows 8 and one with windows 7, didn't work on either.

These are the steps that I've used and have never had any problems with drivers. My brother had the same problem that your having a while back and these steps cleared up his driver problems. Maybe it's worth a shot.
First of all I NEVER let windows automatically install drivers except for a very short time period after a clean install of windows. It makes life easier if windows doesn't jump the gun and try to install what it thinks will work. I always get drivers directly from the manufacturer. After you stop windows from trying to do it's automatic driver install thing plug in your N7 to your computer and open device manager (I usually just type dev in the start search box of W7), find your device, right click and choose Uninstall, check the box for Delete the driver software for this device. When it finishes doing that reboot your computer and unplug your N7. Once your computer has completely booted back up plug in your N7 and open the device manager again. Find your N7 again, right click Update driver software then choose Browse my computer. Find your folder (including the subfolders) with the drivers and let it install, once it finishes unplug your N7 for a few seconds then plug it back in and hopefully it should be all good. If your want it I have a copy of the usb drivers at dropbox from my recently updated sdk install. I would just extract the folder and point the install to the whole folder, if you included subfolders at the install it will find what it needs inside the folder. Make sure you authorize your computer with usb debugging. Good luck! ; )

As regards the attaching of files, you have to have a minimum number of posts to be able to do that.
As regards the USB, be a little more specific like what you are trying to do, which ROM you are running, whether you are rooted, what happens when you connect the phone to PC etc which will enable the members to help you.

There could be several reasons for this, but lets start with the basics.
Have you tried a different cable?
Have you selected File Transfer (MTP) from usb options?

I get a windows sound like its connecting then in the bottom right where the time is next to that is a root sign then I get a pop up saying exactly.....The last USB device you connected to this computer malfunctioned and Windows does not recognize it. Recommendation.. Try reconnecting the device. If Windows still does not recognize it, your device may not be working properly. When I go to the Device Manager/Control Panel it doesnt do anything. I've tried to add adb to the path but maybe added it to wrong path now it won't come on. If there is a work around maybe to re-add to right path. Device Manager was fine before I added adb and added path as per internet search. Device Manager before would say something like error 39. I've tried MTP that doesn't get it to open up either.

I cant even root for the life of me now, Im on 8.0, I'm trying to just root the phone and to start the computer has to recognize it I understand but it won't, with my Oneplus 2 was fine,(I'm thinking maybe phone doesnt have the drivers built in to the file system, you know when you plug in and turn on MTP it shows the drivers app for Windows?) the only thing it errors plugging in.

On my son's pc running windows 10, I didn't have any issues connecting my OP3 to it and viewing files, nor did I have to install any drivers, same for Windows 7.
Hook phone to pc via usb cable.
Pull down notification bar and select "File Transfer" from usb options or go to Settings and search USB and select USB Preferences > File Transfer.
Browse phone from Window's file manager.
If still having issues, you can try and install Oneplus USB drivers, reboot pc and see if the phone can be recognized.

If you are running Win 10, you will have to disable driver signing before the correct drivers are installed. May be that was your issue.
