Hi,
I tried a lot of other rooting applications and have had no luck with any of them. Then I found Wug's Nexus Root Toolkit. It works for my Nexus 4 (Jelly Bean 4.3) - until I came to the "Full Driver Configuration Guide" - where it gives a message: "ADB device was not found".
I have tried it over several times to no avail. Can anyone offer any clues as to what may be causing this?
btw, I am running the Wug's Nexus Root Toolkit v1.7.2 on Windows 8.
Thank you,
David
I was just having the same problem, and I realized after a while that I was making the STUPID mistake of not noticing that my phone was asking me to confirm USB debugging when the toolkit started searching for ADB devices. If you're as big of a dummy as I am (or just having an off day), this may be your problem

I am having the same problem. Where/how does the phone ask you to confirm USB debugging? It asks me when I turn it on, but not again later.
I have tried 3 or 4 different drivers, but, although the device is recognised by Windows 8, it is not recognised by Root Toolkit.

They promote not learning what you're doing or what's actually happening in your devices so... there's posts like this.
please read this thread before touching your device

I'm not quite sure how this was supposed to help. My problem is that the ADB drivers do not seem to work on my computer. I have just tried installing the Android SDK (which comes with its own ADB drivers), having first uninstalled all the existing drivers. It did not help.
Not entirely sure where to go from here.
PDAnet's drivers may work. Simply install PDAnet (after uninstalling any previous attempted driver installations) to get the drivers.

I had installed PDANet from within Root Toolkit, and it didn't work. Just now, I uninstalled everything again, and installed PDANet from their web site. Still get no ADB device in Root Toolkit. [NB I didn't have PDANet on the phone, but it seems to be there now]
I tried running adb from the android SDK, and it says "error: device not found".
However, I noted there was an adb prompt on the phone when I first plugged it in, this time (which I told to always accept).
[Later]
Wierd - it is now a bit further on. This is what I did:
Started PDANet on the phone, and enabled USB tethering.
Started PDANet on the computer, and it connected to the phone. At this point the USB debugging permission thing came up again, and I accepted it (also ticking the box to always accept).
Unticked USB tethering on the phone again.
Stopped PDANet on the computer (right click on icon, exit).
Tried the Root Toolkit again (pressed Root button), it connected to the device, and put it into fastboot mode.
The boot loader appeared on the phone, and the computer said "Checking Fastboot Status".
It seemed to stay like that for ever.
Killed the root toolkit. and tried again.
Left the computer for a while, and when I came back, it had completed.
So, it seems to be working now.
And when you try using fastboot directly instead of the toolkit....... what happens?
changing MTP to camera in USB connection mode did it for me...with MTP it showed correctly in device manager but the toolkit didn't recognise it

I type "fastboot reboot" at the command prompt.
It replies "< waiting for device >"
I wait a few minutes.
Then I press ^C and the command prompt returns.
P.S. Changing the USB connection to camera doesn't make any difference to the above.
Best idea i didnt notice too

I got stuck the same way.
The way to got around was to change connection to camera -> the PC is intalling some drivers,
then turn off the USB debugging -> the PC is again installing some drivers,
then turn on the USB debugging -> "bingo" adb mode recognized by the toolkit
Now I can install and enjoy Kikat 4.4.1 :good:

I found the same solution, changing over from MTP to CAMERA suddenly had the toolkit recognise the phone and could boot it to unlock then root it... Previously, I had installed PDA drivers...
I am astonished how PATHETIC nexus phones/tablets are at simply connecting to a PC. I am baffled at the attempt by google to make their devices as UN-plug & play friendly as possible... bizarre! I have a N10, N7 and have had two N5's and all have the same PITA random disability....
grrr...
Mark.
So the Nexus toolkit is able to see the Nexus 7 as a media device but not Windows ?

So the Nexus 7 toolkit is able to see the Nexus 7 as media device with this method, but not Windows ? That's strange because Windows is supposed to see your files within the Nexus via Mtp mode. Is it that google removed the ability for Windows to be able to see Nexus 7 files in Android kit kat 4.4.2. What should I do then if I simply want to view files inside Nexus as a non root user ? B.T.W I'm currently on stock kitkat 4.4.2 build KOT49H. Therefore, I'd gladly appreciate it if anyone out there would answer this question and thanks in advance. Feel free to PM me on this so we can "talk" about this. : )

Success.
Well, mtp connection works perfectly fine in my Windows 7 machine. But on my xp machine I could never get it to work no matter what driver combination I used.
I can see the reason they changed to mtp but I found mass storage to be much more user friendly.

as others, I was using WUG kit to get back to stock. I was stuck without USB degugging options. Installing PDAnet did the trick, installing drivers so that I was able to get WUG working. I am now stock. All traces on my tinkering are gone. Later this week I will upgrade to a Galaxy Mega and trade in my Galaxy Nexus that I have loved for 3 plus years.

Hi
Happy New Year to all! unfortunately I am left with the unusable nexus 7 that happened last night.
I was going crazy with the lags with lollipop and was waiting for the 5.0.5 update OTA but the delay was making me go crazy so I decided to take the risk of manually flashing the image using ADB and SDK.
Like many others pointed, I knew how to enable my computer to see my device by switching from MTP to PTP mode from my earlier rooting experience with Samsung, HTC and others. So that was not an issue for me.
I was following a tutorial from androidcentral and half way through I went to check a tutorial on youtube which I think caused the disaster. After I executed the adb devices no devices were detected and like I said I went and changed the MTP mode to off and bingo now my device was detected.
I executed device unlock and currently my device is in unlocked bootloaded state which is displayed in the fastboot screen where I am stuck now. Following the youtube instead of flashing each separately bootloader first and then the factory image I jumped to 'flash-all.bat' command...I saw something say on my command prompt on pc that completed in so many seconds or minutes which led me to get anxious and since no rebooting happened on the device I went and manually tried to press the power button.
From that time I am stuck on the fastboot screen. I can cycle through 'power off', restart booloader, recovery mode and start. But when I select 'restart bootloader' it comes to 'start' in the same mode and when I select that I can see a tiny 'Booting failed' in white letters in tiny fonts on the top left side of the 'Start'. I cannot go past this state.
Since I know the last time I had enabled 'usb debugging' and MTP off before everything went wrong I am presuming those states are still intact. I can see status on 'reboot bootloader' screen that my bootloader is unlocked.
Now, when I try to go through the process again my device is seen in device manager but when I send 'adb devices' command it cannot detect any devices. If my device is usable I can atleast go into settings to see if my MTP state and usb debugging status. Now I don't have that option. I even tried the Nexus Root Toolkit - everything is fine but until it tests the driver to finally say 'ADB device not found'.
After browsing so many posts I spotted there were some posts that said there is some discrepancy between the device id as listed by the driver to what actually is usb.inf, which all is too technical and overboard for me. And finally left me thinking that it is some issue of Windows PC as someone pointed that the ADB device was detected on a MAC. So I am now thinking to give it a shot in a mac machine as a final attempt to recover my device.
Anyone please suggest a solution, apologies if this is covered by someone elsewhere in the forum if so please point me there. I will make sure that from next time I will never do a manual flash of factory image.
please help!
It sounds like you are on top of it, but haven't hit the right combination yet. Thanks for the quote and I am sorry I am unable to offer any help. As mentioned in my post, I have switched to the Galaxy Mega and was pleasantly surprised by the OTA upgrade to 4.4. Now I am trying to figure out how to root it.

It seems like I go through this every damn time I get a new Android device, so you'd think I'd have figured it out by now, but I haven't.
How the heck to I get ADB working for this device? It's not being recognized by the "adb devices" command right now. As far as I know, I've got the drivers installed (at least, I could communicate via fastboot). I don't know what else I need to do, and would appreciate any help.

Yes, that's where I got the drivers (and that's how I got fastboot working).
I've taken the drastic step now of uninstalling the entire SDK thing and am currently re-installing it. We'll see how that goes.
EDIT: yeah, "adb devices" still gives nothing at all.
You need to turn it on first but Developer Options are hidden in Settings. Go into About phone and tap the build version. After 7 times you will have access and you can turn on USB Debugging

While this was, admittedly, once my problem back in the early days of android, it's not the problem this time. USB debugging is on.
EDIT: I've also reconfirmed that fastboot is still working after the whole re-installation thing.
Anyone have any other ideas? Is it correct that when I plug the phone in, it's detected add an MTP device?

That's all I can suggest as well, although I can't see what the issue could be
Yer try installing the SDK and downloading the "Google USB Drivers" from there to see if it helps.

You can just get the windows executable from Google, r21
http://dl.google.com/android/installer_r21-windows.exe
Thanks, everyone who's been reading/trying to help. Unfortunately, it's still not working.
People suggesting the .exe installer - that's how I've installed it each time. Twice now I've uninstalled/reinstalled the SDK. When installing, I choose the SDK tools, SDK platform tools, the 4.2 API (which is probably unnecessary, right?), and the Google USB driver. Each time, ADB has worked *in general*, but will not recognize this device (via the "adb devices" command).
Here's how things are going right now. When I first plug the phone in (with debugging on), if it's not currently installed as a device then it automatically self-installs and shows up as an "mtp" device. I try ADB, doesn't work. I then go in and manually install the drivers found in various places around this board. When I do this, it no longer appears as MTP. This is weird, though, and I didn't notice this last night - when I look at the list of devices in Device Manager in Windows, the category it falls into is "ASUS Android Devices", under which it's listed as "Android Composite ADB Interface", and it still doesn't work.
Something seems wrong about it being listed as ASUS, though. I wonder if all these current difficulties are a result of the problems I had getting my Transformer Prime to work with ADB? If anyone sees anything above that looks like I'm doing something wrong, let me know; I think the next thing I'm going to try is doing this whole process on a fresh computer here at work that's never been exposed to android at all, see how that goes. I'll check back in after I do that.

I have, and it still doesn't work on my laptop. However...
It's working! On a shared computed at work that had never had *anything* android-related installed before. Went through the same procedure I did on my own computer, so the problem is with my laptop, I guess. Which I'm more okay with than it being a problem with the phone. I guess I need to more thoroughly remove everything from the laptop, maybe?
An update:
I DO. NOT. UNDERSTAND. why this worked; I haven't changed the drivers or anything on the laptop itself. On a whim, I changed the device type on the N4 from "media device" to "PTP device" and suddenly ADB is recognizing it on the computer where it's never worked. Should I have expected that?

I have to do that to my Nexus 7 before ADB will recognize it, so you're not alone there.
Just curious, what brand phone did you have before? If it was a samsung and you had all the samsung drivers and what not installed still, this could be causing the problem. My cousin couldn't get adb to recognize his device and we finally discovered the samsung software was conflicting in someway. He uninstalled it all and adb worked like a charm.
I had the same problem, here's what you need to do. When you plug it in, change the settings from MTP to Camera for USB settings. I don't know why, but you need to do it.

I've got four other android devices that all worked (simultaneously, at that): T-Mobile/HTC G1, Nook Color, T-Mobile/HTC G2, and an Asus Transformer Prime.
Since I can't post on the actual threads yet, due to being a new account, I will be posting here in hopes that someone comes across this and can help me out.
I have done a pretty hefty amount of reading trying to get my Nexus 7 rooted and for some reason I just can't get past the part of installing the necessary drivers for my computer.
Specs:
- Windows 7 32 bit. (Administrator account)
- Nexus 7 32GB (Wifi) running 4.2.1 w/ OEM cable (Also tried a non-OEM cable)
What I have done so far with Wug's Toolkit:
- Step 1
1. Plugged in my device and made sure USB Debugging was enabled. (At this point, the Device Manager recognized a device and tried installing drivers, but failed.) So the first thumbnail is what I have in my device manager from the start. Nexus 7 under "Portable Devices" and "Other Devices."
2. I uninstalled both of the devices.
3. Unplugged my device and used USBDeview to uninstall anything that resembled "Google" or "ADB", etc. like it states.
4. Rebooted my computer.
- Step 2
1. It says that the recommended solution is #3, so naturally, I tried that one first. I followed the steps and installed the Android Composite ADB Interface drivers successfully and it even shows it under "Android Phone" in my device manager, second thumbnail, when my device is plugged in. (USB Debugging enabled)
2. Now, when I click on the "Reboot Bootloader" button on step 6 is where it just hangs with the dialog box "Rebooting your device into bootloader mode..." but my Nexus never reboots or anything. My Task Manager show two "adb.exe" processes and none ever end. I read the thread and some users were having the same problem and they got it to work by ending one of the adb.exe processes. So I have to end one of them and after a while I get a "Checking Fastboot status" then a few seconds later this message box pops up, third thumbnail. It says that Debugging is not necessary for bootloader mode, so I turn off USB Debugging and my computer recognizes a new device. So it successfully installs Android ADB Interface and I try the Reboot Bootloader button again, and it still hangs. Only this time, there is one adb.exe. So I kill it, and after a while I get the same error dialog box as the third thumbnail. Like it states, I am using driver configuration #3, so I will go ahead and close the dialog box and go to step 7.
3. Since my device is already configured, I go to Step 12.
4. I hit the "Reboot Device" button, but nothing happens to my device.
At this point, I decide to try a different driver solution. So I go through the whole process all over again, with Solution 1. Go through and install the drivers, everything goes according to the tutorial. I get to Step 3, and hit "Full Driver Test" and it hangs on "Checking ADB Status". There are two
adb.exe's so I end one of them. I get a dialog box that says ADB device not found.
Finally, I decide to try Solution 2. So I go through the whole process. Yet I still get the same hanging with adb.exe. I even tried different USB ports, but nothing.
Now, with mskip's Toolkit I never get past the "Starting ADB..." message. It just hangs there.
So the problem lies with ADB.exe I'm guessing. I'm tired and I've spent hours just trying to root this thing. Am I SOL? Anyone have anything that I can try out or the same problems?
Have you tried rebooting your PC after installing the drivers? It took me ages to get mine installed and I think a reboot allowed the device to show up and work properly. I thought it would be easy being a nexus device. Turned out to be a right pain in the ass.
Yep.

Hey thanks for the response. Yes I have. I tried rebooting after every driver change. (Uninstalling, re-installing, etc.) My device does show up, almost as if the drivers are working correctly. Though I'm not sure why adb.exe is giving me troubles.
Have you tried 'adb devices' via cmd prompt? I take it your all stock then?

What I was hoping to do was to create a backup of all my apps and data before I mess around with it. Yes, I'm all stock.

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.

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.

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.

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
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.

Thank you so much for all of this! I'll need all the luck I can get...
By the way, I checked that softbrick option ^^!
All along ADB was working fine. Now when I enabled it, nothing is detected on the computer. The phone went entirely missing. If I turn it off, the phone comes back. Anyone encountered this?
With ADB turned off
- Phone works in PTP Mode to PC
- Phone works in MTP Mode to PC
- Phone works in MIDI to PC
With ADB turned on
- No phone device detected at all. So I am not even able to change to any of the ADB drivers

What do you mean by "ADB turned off" and "ADB turned on"?
Are you talking about USB Debug?

Yes, USB debug in development menu, even turning it on/off, revoke does not seem to make it work again. it just does not show up on my PC.
Further tests done.
Fastboot works.
Adb works in recovery mode when booted into TWRP 3.0.2-3.
Think I need a way to reset the ADB /usb debug settings within the phone as it looks more and more to be an issue from the phone rather than Windows (v7 x64 sp1)

Not the way I read it. Sounds to me like the exact opposite.... a driver issue with your PC/OS, not the phone. In order for the phone to have adb/fastboot capabilities, the correct drivers need to be installed and actually working on the PC. Without going into detail, you could use a few different tools to REMOVE and install the correct PC drivers. Wug's NRT Toolkit has a very good step-by-step driver configuration guide with verification. I now just use the 15 second ADB installer here on XDA because it is minimalist, and just works. That being said, the NRT has a USB removal tool to rid your system of old USB entries that are likely causing your problem. Give it a whirl.

Shall give it a whirl. Previously it was incorrect driver issue years ago but everything has been working fine on all my Android devices till yesterday when I can't seem to ADB to my 6P. I have the latest USB drivers installed via Android SDK Manager.

Still no go. There's no device at all where I need to change/delete/update driver if I turn on ADB USB mode. Phone is only seen by Windows Device Manager when I turn off USB debugging in developer menu. I still feel it might well be something in the developer menu causing this issue.
I am checking on the folder /data/misc/adb . Permissions is rwxr-s--- . What's the permissions you have for this folder?
Using USBDeview (trying to compare between 2 sets of 6P, both with the December 7.1.1 roms)
6P that works over ADB
Reported VID and PID is 18d1 / 4ee2
6P that does not work over ADB
Reported VID and PID is 18d1 and PID is 4ee1, 4ee5 and 4ee8 depending on which mode (PTP/MTP/MIDI).
Nothing gets reported to be connected at all when I used USBDeview while the 6P that does not connect over ADB USB has USB debugging turned on.
Problem fixed. No idea what was the cause. Hopefully it will help someone else who gets this down the road.
Steps performed
- Clean up SU
- Reboot
- No go
- Reboot to Recovery
- Reflash EFS backup
- Reboot
- No go
- Reboot to recovery
- Clear cache, clear dalvik

Puzzling.
Glad you got it fixed.

Yeah, would have done a full factory reset if all else fails since the hardware was indeed able to connect to my PC properly. Glad the various flashing worked out.
