ADB device not found - Nexus 7 Q&A, Help & Troubleshooting

Sorry if this issue has been addressed in another thread but I could not find anything. I am trying to root my nexus 7 v2 with the wugfresh 1.8 toolkit. But when I try and do the driver test it says not found. I have tried the steps suggested with the toolkit to try and resolve but no luck. I know my PC recognizes my device, the only thing I can think of now is that I don't have the OEM cable because I purchased my nexus from a friend. Any help would be great.

Nexus devices are easy to root. You dont really need a tool. Just make sure you have fastboot connectivity and type fastboot oem unlock. It will wipe device and unlock. Then fastboot flash a recovery and use recovery to install the supersu zip. Or use recovery to install a Rom.

V2 indicates 2013 model... That is not this forum. This forum is for the 2012 version

Sorry about wrong forum, and I know I don't need the tool kit. But just the problem of it not being able to detect makes me nervous of attempting other methods of rooting

Rooting is really just a file you install from recovery. All you need pc for is to use fastboot to unlock ans then flash recovery. Either it will see the device or it won't. If using Windows 8 though I would try a different os as Windows 8 is a royal pain. Good luck to ya.

There's no one click method I know of for the Nexus S.
What do you mean you can't root & it won't budge? This phone is about as easy they come (without some one click app): http://forum.xda-developers.com/showthread.php?t=931865
Install the android sdk on your computer.
Put the su.zip file on your sdcard partition of the phone.
Put the phone in fastboot mode.
Fastboot flash the recovery.
Select recovery.
Select install zip from sdcard.
Flash it.
Reboot.
You're done.
If your computer doesn't recognize the phone while it's in the bootloader, you gotta install the google Nexus S drivers or the one from PDAnet. That was where I got stuck at 1st when I tried rooting. Fastboot couldn't find my phone because I had the generic windows drivers.
Also if you have PDANet on, turn it off before putting your phone in fastboot mode.
Actually there is a one click method...brb with it
http://www.theandroidsoul.com/easy-one-click-root-for-nexus-s-full-guide/
Or search superboot nexus s
Here on xda
Either will work PC or mac.

Interesting. So the steps on the referenced one-click method you posted are:
1) put your phone in fastboot
2) do the fastboot oem unlock command manually.
3) run a batch file that contains two lines (fastboot-windows.exe flash boot boot.superboot.img & fastboot-windows.exe reboot).
I guess that's easier than putting your phone in fastboot directly and typing in a command to flash clockwork, then selecting a zip file to install from clockwork, but not much.
The drawbacks here are of course that it's superboot, and that it requires you to unlock the bootloader. I guess it's useful if you're really noob, but it only saves you typing one command.
The noob part is very true. However I prefer my bootloader unlocked anyhow.

Why do you prefer it unlocked?
I like the unlocked lock! No seriously custom roms etc.

main reason i think there is no one click root is because its so simple to do on this phone

You do not need an unlocked bootloader (currently) to use custom roms, or to root, or to flash clockwork recovery, etc...
On day one that wasn't a known entity.

Of course, but since you contradicted my statement earlier that one disadvantage to the posted method here was that it had you unlock the bootloader by replying that you like having yours unlocked, I was trying to pin down if there was an advantage to unlocking the bootloader that had been discovered that I hadn't heard yet.
There's indication on git for our phone that the next update includes a change to the bootloader being able to use the fastboot boot command while locked. Unknown what that will actually do in terms of just fastboot flashing clockwork to apply root and custom roms.
I c wut u did there. I'm not sure how the update is going to affect things ATM. I keep it unlocked for "in case sh*t" happens. Never know what an update will bring in changes to rom management.

[Q] Restoring Stock Android on Nexus 7

Hi I have a problem with my Nexus 7 (32 gb wifi only version).
My son in his infinite wisdom decided to install ubuntu on the tablet.
I went to try and restore this back to the android version but all it did was to wipe off ubuntu itself
I then went on jayceooi.com and used the nexus toolbox to see if I could reflash the images etc.Howveer although all the files were downloaded I canot get the laptop to recognise the nexus itself (even though it sems to charge the tablet). There is no menu at all to check whether or not usb debugging is ticked or not..
Im now left with the tablet without no apparent operating system. At the moment all it shows is the green android with fastboot mode but when I hit start it says booting failed.
Could someone help please before I do any more damage and I brick it completly (although I may have already done so)
thankyou for any help

Yes it can do restore back to stock. Just follow the guide to unlock bootloader so it can flash stock image then just re lock bootloader. It covers the process in op.

Ok thanks all. Seemed to be doing everything ok but its been stuck on"waiting for your device to finish booting back up" for about 30 minutes now. It did say it would take 5 to 10 mins but should i carry on waiting or abort and start again do you think?
thanks
I would reset it see if that helped
Sent from my Nexus 7 using Tapatalk 2
If your son re did the partitions for Ubuntu that could have messed things up pretty good. I have only had my nexus for a few days so I couldn't tell you how to fix the formatting quite yet. I would search around on how to verify and correct the partitions if needed.

[Q] PLEASE HELP!!! Cannot connect to computer!!!

Hey everyone, thanks in advance for the help. I just got a nexus 4 yesterday, that was already updated to 4.3 when I got it. My problem is when I go to unlock the boot loader, it won't recognize the phone. It says "list of devices attached" but doesn't give a serial number. Also, before this, it was giving a serial number, but was saying it was offline. So I uninstalled and reinstalled the drivers. Any help is most appreciated.

You might need updated adb/fastboot exe/dll's. Grab them from a toolkit, that's what I did.

Try this... When you're connected to the PC , toggle USB debugging off and on.. It might ask for authorisation of ur PC in your phone.. Give yes.. Then do adb devices .. You might fight the offline thing gone

I did that, got it to boot into boot loader through adb, then my fastboot drivers wouldn't install. So I uninstalled everything and started from scratch and now I can't even get the serial number to come up.

Hmm.. doesn't it get shown as Android devices under device manager?
I too had a similar kind of problem with adb. I uninstalled the drivers manually and installed it again using Koush's Universal ADB (Android Debug Bridge) Driver for Windows. It has fastboot thing also. It worked for me.

You can also try someone else's PC or something. Install the drivers using the above link and just fastboot. Sorry, if that is of not much help. I'm new, both to this place and to this Nexus 4 device as well. All the best.

Bought google nexus 4 lg, an error

When I try to install busybox, i get this..
there was a problem opening a shell with root access. this is either being caused by superuser/supersu or by a device that is inproperly rooted.
try removing superuser/supersu permissions, uninstalling this application reinstalling this application and then regranting superuser/supersu permissions for this application.
you can check your device to see if it is properly rooted b y downloading rootcheck from the android market.

I downloaded an app bootunlocker from store, i get bootloader status no root access..both lock and unlock buttons disabled.
I downloaded supersu from store..i get there is no su binary installed and supersu cannot install it. this is a problem!
if u just upgraed to android 4.3 you need to manually re-reoot- consult the relevant forums for your device.
For one, don't complain that you're too lazy to read through a post. People on here aren't here to babysit you, we're here to assist you in fixing your device, not fix it for you. I'll help you this time, but don't do this again, because this is ridiculous. If people always tell you step by step, you're never going to learn anything. Anyway, what you'll need to do is download Wug's Nexus 4 Toolkit (its a sticky in android development) and then click unlock boot loader + root, if the root part fails, go to chainfire.EU and download the latest flashable supersu zip and flash it.

You shouldn't need a terminal, if you go to the android development forum for the nexus 4, you should see Wug's Nexus Root Toolkit, it should have a link in it. Click it and follow the instructions to download. Install that then start it. It should have a button that says unlock device + root

Make sure you install the USB Driver. You should be able to do it from the root toolkit. Its the button to the very left IIRC.

i did the steps. in installation.
uninstalll , reboot my pc... then install option 1 ( step 2).. then step 3 do a driver test..i still get adb device not found.
