Can't get Fastboot to recognise Nexus 7 under Win7 x64

I've tried the latest revision Android USB drivers from the SDK platform updater. I've tried PDANet and the Universal Naked Drivers.
Basically, ADB works great, but as soon as I "adb reboot bootloader", my Win7x64 says "USB Device Not Recognised".
I've already gone into device manager and tried manually updating the driver to the various ones I've downloaded. I've also tried "uninstalling" the driver and reinstalling it, but it keeps coming up as unknown device.
When I type "fastboot devices", nothing shows up (obviously).
What am I doing wrong?

Same thing happening with me, i want to re-lock my bootloader but when i am in bootloader mode windows does not want to recognize the device, i have tried everything too.

Did you install the correct drivers?

When connected and in the bootloader open the device manager in windows. You should see "android 1.0" near the top.
Update that driver. It should work.

Hey, As i said earlier i was having the same problem...try switching your usb cable then try. That is what fixed my problems.

ive done all mentioned above, even tried 3 different cables, no luck, anyone have suggestions

I dont know about what you want to do, but if you want to root and unlock use the wugfresh took kit. Its the bomb and as soon as I figure out where I can thank him and give a big kudos I will give thanks.

I could be wrong, but I don't think adb works from bootloader, but the fastboot command should. I think you can also use Google's Composite ADB Interface driver too for it (I can't reboot my N7 atm or else I'd find out).
I don't have any other android-related drivers on my system either, only Google's USB driver from the SDK. I'm also on Windows 8, but I would assume Google's USB driver would work fine on Windows 7 too.
Also certain USB filter drivers may cause issues too, such as libusb, or even AMD's USB filter driver (however, I had no problems). Or if you want to wipe out any/specific USB drivers, I recommend getting: http://www.nirsoft.net/utils/usb_devices_view.html

[Q] USB and recovery problems after OTA upgrade to 4.3

I took the OTA to 4.3 on my Nexus 7. It was previously unlocked and rooted, but had no kernels, etc changed. After the update ran, I lost root as expected, however, in trying to get it back, I've discovered I'm having a couple of other issues.
First, the device is no longer working properly via USB on my PCs. On both my Win 7 and Win 8 PCs, the device won't properly connect to where I can browse files or anything else. On the Win 8 computer, I see a Nexus 7 device in Device manager, but drivers won't install. I downloaded the drivers from the Asus site, but trying to manually install them doesn't work on the Win 7 machine, and on the Win 8 machine, they install but don't seem to be working with the Nexus 7 as it still shows a problem in Device Manager.
The tablet also will not boot into recovery mode. I can power it up into fastboot mode, but if I select "Recovery Mode" and hit the power button, I just got the Android with the red triangle for a few minutes before it boots back into the OS. After doing some searching, I saw where you might need to have it plugged into a PC to get it to go into recovery, but that doesn't work, either (might be tied to the USB problem).
Ideas?

Did you turn on developer options, and USB debugging? Have you tried USB connection type PTP instead of MTP?
If you have the stock recovery, the red triangle and Android are normal. You can bring up a blue options menu by pressing the power and volume up buttons from the red triangle Android.

Yes.

Try another driver source. Wugfresh's installation is a lot tougher than Skipsoft's, but try the other guy 's system.

I was using the stock drivers off the Asus page. I'll look around for the two you mention. I assume they're posted on here somewhere.

And about the recovery just try flashing another recovery from fastboot

Without USB access? That's my dilemma.

OK, I'm getting closer. I got TWRP installed and rerooted it. I had to do the "Revoke USB debugging authorizations" on the Dev Options screen. Then it would work via ADB.
Still not browsing files yet on my desktop, but at least I know I'm talking to it. So now I'll play with the driver installation a bit.
EDIT: Well, drivers reinstalled for about the 4th time, and it's still not allowing me to browse files from my desktop. Galaxy S4 works fine as soon as I plug it in, even if I also uninstall it's drivers. Ideas? I obviously have it working over USB because I can give it commands and reboot it via the PC.

OK, try this one. Plug in your tablet to pc, go to hardware manager, find your Android Device then choose Uninstall (choose Remove all drivers for this device), unplug and plug in your tablet again. Your Windows should discover few new devices (mine has discovered three) and download drivers for them then you should see Android ADB Interface in Android Devices and Nexus 7 in Mobile Devices.
--edit--
I've solved my issue

Already been done that road multiple times.

have the same problem except one thing: no one 3 computers don`t detect my nexus. have no reaction in device manager, on connection nexus as mtp/debug/fastboot. Only usb-otg works.

After you plug your nexus in have you unlocked the screen to see if it is asking you to authorize the tablet?
What other steps have you taken? Have you installed proper drivers? Have you manually chosen to update drivers with the sdk drivers if in device manager is showing the nexus? Have you tried the drivers from Asus?

I personally did all of those things. After having the Nexus "forget" all the other PC authorizations on the dev screen, I finally got it to accept ADB commands, just not to properly install drivers that would allow me to browse files like it had done on 4.2.

Nexus doesn`t appears in device manager. At all. It starts to charage, but no reaction in device manager, no any reaction(except charging) at nexus. On computer it looks like i didn`t connect anything. I`ve trying to intall drivers as legasy hardware, but nothing changes. Sorry for my english.

Try turning off usb debugging. My tablet cannot connect to pc but with usb debugging off it at least recognises tablet as a media device and this enables me to view its files
.but still the problem of not being able to root

[Q] Google usb driver problems

I have been having a difficult time getting the right usb drivers for my 2013 nexus 7. I have tried the manual download fron SDK, various toolkits available (wugfresh, etc.) with no success. The furthest I got was when I tried to unlock with the "fastboot oem unlock" command, i got a "waiting on device" message.
Is there a problem with Windows Vista loading these drivers.
Please help!! I'm about to throw this tablet through the window!!

For adb and bootloader, use these drivers direct from Google:
http://dl-ssl.google.com//android/repository/latest_usb_driver_windows.zip
You might have previous attempts at install or previous drivers blocking the proper install.
Use Nirsoft USBDeview to get rid of any old Nexus 7 entries

I did that on the wugfresh toolkit, but still have issues loading a good driver that will let me unlock!

Even worse trying to find a driver which works across multiple devices..
what makes the android USB driver situation so unstable? shouldn't the devices just meet the MTP spec and no driver updates would be needed?
(obviously that is not true, but)

It has been a painful process, at least in my case. By watching the videos it seems simple. I have seen where Samsung drivers have worked in some cases. I'm wondering if Vista has something to do with it. I couldn't get any of the wugfresh toolkit drivers to work, which even had Samsung drivers. Then, finally windows loaded a Composite Android Device driver that let me get all the way to the unlocking command then said "waiting for device"??? I really want to root this tablet!!

The devices don't alway advertise themselves as MTP compatible so the OS doesn't know to use the MTP drivers. It is a bug in the implementation on those particular devices.
For example, Nexus 7 2013 advertises MTP compatibility when USB debugging is turned off, but stops doing so when USB debugging is turned on.

Bricked & Unseen...

Ok, here goes my story.
Just a week ago from the date this was posted, I decided to update my recovery (TWRP) through ROM Installer. Surprisingly, I didn't see TWRP at all in the "Recoveries" section of the application. Stock, ClockworkMod Touch, regular Clockworkmod (no touch), and unofficial Clockworkmod were available - from what I can remember. I decided to use Clockworkmod (no touch) to install Paranoid Android. Coming from OmniROM, I factory reset and flashed the .zip.
Flashing ended in error with Status 7. A while before I had used ClockworkMod Touch to try another ROM and had no such issue. I ignored the error and restarted my tablet hoping that it would still boot fine. It rebooted, gave me the Google logo for about 5-10 seconds and automatically rebooted into recovery.
I saw a bypass for Status 7. Removing some lines from the updater-script was the solution. Having no access to my Nexus 7 storage, this bypass is unusable
I tried flashing a new recovery using flashboot fastboot. After verifying that I had my drivers installed (Universal ADB by Koush), I opened up adb in the command line (Windows) as an administrator. I could not see my device. I tried the drivers from Asus, multiple USB 2.0 ports, and a different USB cord, but same results. I tried on a different computer. Still no detection.
Systems used: Windows 8.1, Windows 7 (x64), Windows 7 (x86)
I tried using Wug's Toolkit and used Flash Stock + Unroot, since it didn't need USB Debugging enabled. Same results...
I also tried plugging in another Android phone (LG Optimus Dynamic II) to see if Windows would recognize it. Windows recognized it, installed drivers automatically, and was recognized in ADB immediately. This practically unknown phone (XDA doesn't have a section for it yet) could be recognized, but my world famous Nexus 7 2012 can't be seen.
I have absolutely no idea of what to do now...

Are you on the bootloader screen when trying to use fastboot?

Yes. Every time I use fastboot, I am in the bootloader.
I'm not new to this at all, so say whatever you need to ^^
The main problem is my PC not recognizing my Nexus 7 through adb. Again, I have used multiple cables with no success.
The computer I am using for this runs Windows 7 x64. I have only tried using USB 2.0 ports to connect my tablet.
Thank you!

Might try deleting the drivers and starting over. I had some issues with adb drivers for both the N7 and the kindle fire on windows 7 as well, but eventually got both working by doing this several times.
I'm assuming you ticked the option for softbricked when trying the flash stock option? If not try again and check that option.
This thread http://forum.xda-developers.com/showthread.php?t=1907796 has a section on driver installation with good info and links too.
Hope that helps. Best of luck man, getting the adb drivers working properly seems to be finicky sometimes in my experience, and i'm no stranger to PC and software troubleshooting either.

USB driver trouble

Ive been searching and trying for quite some time now for a solution but I have yet to find one.
My problem is this, I've soft bricked my Nexus 7. I can get into fastboot and recovery (CWM).
My computer has had a fresh install since i rooted last, now when i connect with USB it doesnt even come up in device manager. Everything ive found online tells me Windows will automatically detect the device then i can update the driver. But i cant even get that far!
I was wondering if anyone could PLEASE help me figure this one out? Is there some way to force Windows 7 to install a USB driver for Nexus 7. Ive downloaded the specific driver.
I'd hate for my Nexus 7 to end its life this way.

Did you try with wugs toolkit. It should have multiple solutions for USB drivers.

I tried Wugs toolkit... also step by step, manually in SDK but Im always getting stuck at "Windows will automatically detect your device" because it doesnt.
the only solution i can think of is to get another nexus 7 to install the drivers and take it from there, but thats a leap i'd rather not take unless it's completely necessary. Even then there is no guarantee that it will work.

Are the latest chip set drivers for the computer installed correctly? All windows updates and drivers? Tried another USB device, cord, and port? Of the 5 ports on my laptop only 1 works for adb and fastboot.

When using WUG's Toolkit be sure to use the USB deview tool inside the driver section.. Remove all of the entries with the Vendor IDs listed in the tool dialogs.

Interesting that some of you have been able to get adb working. I've tried every possible USB drivers and cannot get adb working for my nexus 7, nexus 10, or Acer iconia A1-830. My phone still runs android 4.2, connects no problem. There is no solution, must be because I'm still running winxp on laptop
