Hi All:
I have the 16GB N7 (2013) with USB debugging enabled. I plug into my Windows 7 box via USB 2.0, and it successfully appears in my device manager as 'Google Nexus ADB Interface'. I just downloaded the current Android SDK, however when I run 'ADB devices' in the command prompt, ADB does not recognize any devices.
Any ideas?
Thanks!
Did you try if it would recognize your device in fastboot bootloader?
Go into I believe its called SDK manager and make sure USB or Google drivers update is checked and then click Install as this will install all drivers needed. But prior to that uninstall any drivers in device manager for your nexus 7 . it should pick it up right away after everything installs! Good luck

Thank you for the suggestion, highwaybandit. I tried your idea, but still have the same issue with ADB not recognizing the device, despite the device showing up successfully in Windows device manager.
I have the same problem with Ubuntu. I tried "adb reboot bootloader" and nothing. Unlocked fine with fastboot tho.

Yes, and it does. I was able to 'fastboot oem unlock'. However, can't issue any adb commands.
My Nexus 7 will not show up as a drive on my computer. Drivers are installed, shows up in device manager fine, uninstalled and re-installed drivers, usb debugging is on. I cant see it has a drive so I can transfer files. Any help would be appreciated

Now that you mentioned it, same issue here, in addition to the ADB issue mentioned above. My N7 doesn't show up as a drive whether I have USB debugging enabled or not.

mickrg123, I forgot to mention: I've been getting around this issue by using Google Drive. Not as fast as moving files directly, but still a decent workaround until we get this figured out.

If you have USB debugging enabled, the USB IDs change and for some reason windows can't find the MTP drivers for the device.
If you turn off USB debugging, then the phone shows up as an MTP device (ie it shows up as Nexus 7, not a drive letter)
If you want it to show up as a drive letter, you probably need to root and enable USB mass storage, otherwise it will behave as an MTP device (ie it behaves more like an FTP server than a USB hard drive)
If you have USB debugging disabled and it still won't show up on your computer in MTP mode (ie labeled Nexus 7), then you probably have some problem with MTP on your PC.

Generally, if it doesn't show up at all with adb devices, then it is probably driver problem, cable problem, port problem, or USB debugging didn't properly get enabled. Although since you say it shows up in device manger, it would seem to show that USB debugging was enabled, so you might want to look at driver, cable, or USB port issues (try USB 2.0 port if you are currently using USB 3.0). You can get updated drivers here:
http://developer.android.com/sdk/win-usb.html
You can force windows to update driver by right clicking on the adb device entry and going through the tabs until you find the update driver button.
If it shows up but says device offline, then it is probably the RSA security introduced into adb/android since 4.2.2 (in which case you should update your platform-tools to 16.0.1 or greater)
Also when I check box to load camera it will show as drive

I don't care if doesn't show as drive but doesn't even show as nexus 7 so I can't root until I can load su onto sd card.
Have tried different cables and ports. I heard beep when it connects and shows in menu to to eject nexus 7
Any other ideas?

If you have USB debugging enabled, then my experience is Media device (MTP) mode won't be recognized because it can't find appropriate drivers (even though you have the MTP drivers installed) but Camera (PTP) mode will still work. I don't think you really mean it shows up as a "drive" as in mass storage device. I think you mean you see a folder where you can access your files.
If you disable USB debugging, than both MTP and PTP should work.

Yes you're correct shows as a device not drive when in camera ptp, but not when mtp checked. Where do you disable mass storage?

Sorry, I meant disable USB Debugging, not mass storage (I'll correct the post)
I'm sure you know where, but if not, Settings->Developer options->USB debugging
If MTP still doesn't work, then see if you have ever gotten MTP to work on the PC (ie another device in MTP mode). If not, look up how to install/reinstall MTP support for your OS version. Windows added it as part of user driver framework and one of the new versions of media player.

If your goal is just to load files onto the sdcard, have you tried "adb push"?
You don't need to have the phone visible as a device/folder on the computer to use adb to place files on the tablet.
Im having trouble with mine also. Adb sees it when its in normal mode. When I go to bootloader, it is not seen. When i go to unlock, it just says waiting for device. Any ideas???? Updated SDK installed

1. Plug in nexus 7, MTP mode
2. Open the device manager
3. Right click the nexus 7 > uninstall drivers > unplug
4. Install drivers > http://developer.android.com/sdk/win-usb.html
5. Plug nexus 7 in, drivers will install, should say adb interface
Open up command prompt > nav to your adb folder > adb devices: device number should pop up. Good to go.

For me, when I rebooted the phone into bootloader mode, it came up with a new USB device "Android Bootloader Interface". I had to point the driver install at the Google USB drivers I had previously used for the ADB interface so that the Bootloader Interface could be recognized.

Finally got it!! Had to uninstall and re install the drivers a few times and also remove MTP from device manager. Also had to do the same thing and point it to the drivers in both cases. Thanks. Also thanks to teh roxxorz!

No problem guy; glad you're up an flashing.
I know my way around fastboot, adb, command line pretty well, but I just got my N7(2013) last night, so in that sense, I'm a Noob.
Questions:
Can I just root with SuperSU without TWRP? Or will the stock recovery not let me do that? i.e. is there a signed SuperSU? I would rather keep my stock recovery, if possible.
After I root, do USB storage devices connected via an OTG cable "Just Work"? Do I have to manually mount them? Does it enable a Menu?
Is there any way to enable USB Storage (The other way, when N7 is connected to PC) once I root? Is anybody working on this?

Suggest you do
fastboot boot twrp.img
instead of flashing twrp onto the tablet's recovery partition
This will run twrp temporarily to install SuperSU's update.zip but will leave stock recovery on your tablet untouched.

Recognition is automatic. Mounting is not. So yes, you need to mount them. Whether you do that manually or through a helper app like stickmount is up to you

Doubtful. N7 doesn't have a real sdcard partition formated fat32. It has a simulated sdcard kept in the /data/media folder. MTP/PTP are the only ways Google wants to support storage going forward.
Thanks, sfhub;
Great trick about running twrp once.
That way I can have root, and my stock recovery.
Thanks for the other info, too.
No MTP or Storage show on PC
I am running windows 7 64 bit and I have managed to get root on my new Nexus 7, but now when I plug my tablet into the PC it says on the tablet connected as media device, but it never shows up anywhere on my pc so that I can transfer files on to it. The nexus 7 never shows up as an extra drive or as an media device. Please help. can not seem to find any info on this problem. the usb icon at the bottom of the screen does say eject nexus 7 when I click on it, and if I have usb debugging turned on it says ADB device connected but I still can not see it anywhere on the pc. Please help
Are you running stock or custom ROM?
If you running stock, you can try disabling USB debugging or try this:
http://forum.xda-developers.com/showthread.php?t=2391236
If you are on custom ROM, it appears there may be an MTP issue with some ROMs.
Yes I am using the stock rom .all I did was root it and I have tried with no success with usb debugging turn Off as well. I have even tried to uninstall the drivers I used to root the tablet , but can not find them to uninstall or delete them
In devmgmt.msc the device is either listed under
Android Phone
Imaging device
Portable device
Unknown
Do you see any ? or unknown devices?
In Devices and Printers in the control panel its listed under Unspecified as Nexus 7 but you can not do anything with it there but right click on it and hit eject or properties and it says Google Nexus ADB interface ___ Android Device ___ status working properly and that's it .In Device manager it listed as Android Device ___ Google Nexus ADB Interface.
I Got it Thank you Thank you. I was able to uninstall the drivers there in the Device manager, unpluged the Nexus 7 plugged it back in it install the correct drivers and I am now able to mount my device as a MTP device and transfer files. Thanks again for the Help.
I put Android File Transfer on my Macs:
http://www.android.com/filetransfer/
and gmtp on My Ubuntu Ultrabook, and on my old Xubuntu desktop.
I put the SD card in the Ultrabook, and copied everything I wanted to the N7(2013).
In all cases, it worked pretty much plug and play, but I still consider it a work-around.
im not sure if ive been looking in the wrong places but i cant find an answer to my problem. so i rooted my nexus 7 about a week ago and installed twrp. everything was working fine until i accidentally pressed wipe data instead of factory reset. i deleted EVERYTHING on my tablet including my operating system, the only thing left was twrp :crying: today my otg usb cable came in and i installed that unofficial cyanogenmod build and now it wont connect to my pc. i have usb debugging on and everything. i go to device manager (on my pc) and it is listed as "Nexus 7" but when i try to install the usb drivers it says that they dont work for it. how can i get the usb drivers to work again?
Note: its not my pc cause my rooted s3 works just fine with my pc.
sorry for being a noob! and thanks for the help!
I actually have the same issue where my Windows won't let me navigate my N7 as a portable device. Tried a whackload of drivers and the like to no avail. To transfer files I just end up using ES Explorer. Funny enough, ADB in recovery works just fine.
If it is the same as PA and PAC, try Settings > Storage > Press Menu > USB > Check MTP

Were you on stock before you wiped? Trying going back to stock and see if you can get MTP working, then start introducing the parts until you figure out what broke.
The USB IDs for the MTP device change more often than you'd expect causing recognition problems.
For example, on stock, with USB debugging enabled, it advertises one USB ID and also sends out a MTP-compatible flag. When USB debugging is disabled, a different USB ID is sent, minus the MTP-compatible flag.
I helped someone on a different ROM force the MTP device drivers to associate, but then the drivers couldn't initialize the device. This might indicate there is a problem on the ROM side.

If your ADB works in recovery then you must have installed some other adb device driver, other than Google's, at some point.

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.

I am already rooted and on xposed using a win8.1 laptop. Followed the root guide by Heisenberg (sdk and adb drivers etc), however, on my desktop running windows 7 64 bit, I am not above to get my phone to show up with MTP. The option PTP however has no problem.
ADB is recognized in windows, but fastboot and adb are not recognized when in bootloader mode
Switching over to Win8.1, I have no such problems. Tried searching for win 7 updates and drivers but not much luck there, still cant get device manager to show the nexus 5x.
I prefer using the win7 as it is my main desktop versus the win8.1 which is a laptop that I leave mainly in the office.
Bump for this, Windows 7 users help!
Have you tried "uninstalling" the 5X device in device manager?
After that re-plug the phone and it should reinstall the driver.
Do this for both in Android and in bootloader.

Well, you can't use adb in bootloader mode because that has never been a thing.
adb is available only in Android system and recovery mode.
All you can do in bootloader mode is to use fastboot to unlock bootloader, flash images and wipe partitions.

Ok just done it. Damm, at least 1 problem is solved
I followed your instruction and uninstalled the Google Adb Interface in device manager (didnt tried it at first as this was installed properly) and reinstalled it pointing the path to the sdk drivers, now I got fastboot in bootloader and adb in recovery respectively. In recovery mode, my nexus 5x shows up as a storage drive in my computer which allows file transfers However upon reboot, adb is not detected in android system and 5x not showing up in computer drive still.

What I had was
Android>Google Nexus ADB Interface , this works fine for adb and fastboot
Instead of Portable>Android, I had Unknown Devices with a exclamation instead hence the uninstall and reinstall would not show it as Portable android, only as unknown device.
Solved:
Solution for me would be clicking the notifications in the bottom left. saw that a Nexus 5x was still attached as a hardware even though the storage was not shown under computer.
- Uninstall the unknown device, 5x is still shown as attached in notifications
- Right-click the "safely remove hardware.."> open devices and printers and double click 5x
- Choose Update device drivers and point the path to the universal usb drivers ( android sdk)
5x mtp storage is now showing under computer drives but adb does not work in android system, only recovery. Good enough for me
Thanks alot for your help and time!!
