how to unlock bootloader 4.2.2?
yes usb debugging is enabled

I assume you are using Google Nexus 7 Toolkit?
If so there should be an option which says unlock bootloader.

I feel your pain as I too am having the same problem. I am posting on here so I can easily follow your post. I will tell you also that I think it has something to do with 4.2.2 but not positive at this point. I have rooted a Nexus One, HTC Dream, SGH679, so I do have some experience with this. I have changed ports, cables, started and stopped the service, rebooted the tablet, toggled the debugging just keep getting the offline. When I plug my phone in and use it, it sees it and it works fine, then when I plug the tablet back in it go back to offline. I even removed all the drivers on the computer just so it would get confused with the phone driver and still no luck. I think the driver is fine tho because it says it is in device manager, and I can transfer files back and forth from my tablet to my computer. Don't loose heart tho I think the answer is out there and I will keep working on it, and checking back to see if anyone else has had success.

Have you tried updating the data files in NexusRootToolkit?

So I was going to do it the old fasion way by following this guide
http://forum.xda-developers.com/showthread.php?t=2150661
I didn't quite get step four because the nexus 7 doesn't have an SDcard, but I copied the zip to the root of the device.
When I did step 7 the device did not go to Fastboot, it didn't go anywhere other than a black screen. I think I have a faulty unit, or the holding of the volume buttons with the power is really not the way to get to fastboot, either way I am looking at a brick right now. Any thoughts will be welcome. I messed around with it for 10 min now and got the device to re-boot. Not sure if I should try the fast boot option again.

Are you on Windows 8 by any chance?
Because I couldn't get it to work on Windows 8 and had to use Windows 7.

You must update adb command from here:

I got exactly the same problem and now it works for me.

everyone i got it working! adb offline fixed
It took me a while but I finally fixed it! Here's what I did I went crazy and searched all over the web with the keywords adb offline nexus 7 4.2.2 I then found a website that related to my issue it said to update SDK manager so I downloaded the manager then found android 4.2 next downloaded all that was under the 4.2 package and next downloaded the extra packages next thing I knew I plugged in my nexus and on it on the screen it told to choose yes or no on USB debugging and that's all you have to do to fix the problem of the adb offline bullstuff. I hope you guys will be able to understand what I'm writing to you. I also use windows 7 for this.

FWIW, here is my experience:
PC: Win7 Pro x64 SP1 - SDK platform-tools 16.0.1 - SDK Tools 21.1 - ADB v 1.0.31
N7: JDQ39 Stock *
( *OK, i diddled default.prop in my boot image to set "ro.secure =0". I don't know if that could make a difference or not )
The Nexus 7 asks for confirmation of inbound adb sessions for every new adb server invocation on the client PC.
When it does ask for credentials, you have to get to the on-screen display pretty quickly - a couple of seconds at most. If you don't the device will be reported as "offline" by the first invocation of
adb devices
If you accept the connection, the next time you run "adb devices", the status is back to normal (reports "device" instead of "offline").
You can test this out yourself - just iterate in a loop these three commands:
adb devices
adb devices
adb kill-server
Nothing that can't be understood by someone who knows what is going on; but I suppose that all the toolkits are running adb underneath the hood, so it is certainly possible to get tripped up when using a toolkit if you aren't Jhonny-on-the-Spot when that dialog pops up on the tablet.
Also, for the adventuresome:
I note that the new stock JDQ39 (4.2.2) ramdisk has a new line in the default.prop that was not in JOP40D (4.2.1) :
Code:
ro.adb.secure=1
I suppose that could be toggled off if you have a favorite kernel/ramdisk setup and you don't want to be bothered by this stuff. But it does mean unpacking/repacking your boot images.
cheers

I'm having the same problem. Never recognizes an ADB device. When it does it shows my serial number followed by "offline."
Any ideas? I'm ready to return this thing.

Out of curiousity what driver are you using and how are you installing it?
Also where is your device coming up in the device manager?
I've tried so many things that I think I'm getting off track. Sadly my motorola phones were much easier to root.

how come you cant?

The sad thing is I have no idea what finally got it to work. Maybe just an extra reboot I had forgotten at some point. I do know however that I had to add a few extra lines (hardware ID) to the .inf file in the usb driver. Not sure which did the trick. I also used a combo of the toolkit to unlock and the manual method to root. Also I am unable to boot my device into the bootloader/fastboot via windows and rather have to manually (physically) shut down the device and enter the bootloader via the physical buttons. Probably an issue with the windows drivers again, but at least I have full functionality once in fastboot.
Only thing is now I can't get access to the storage via windows. And there's no way in hell I want to change the ADB drivers without knowing which finally worked for me. I'm thinking though that this is an entirely different device in device manager (I'm obviously not that knowledgeable).
Also I'm kinda annoyed by the unlocked padlock symbol on startup. I suppose that should be a welcome sign of achievement after spending all day trying to unlock/root, especially for such an unlearned person as myself.

did you clear this issue?

This issue is included in 4.2.2, and ADB is disabled by default for security.
I tested on my Nexus 4, 4.2.2 running. :fingers-crossed:

Okey. So to summarise: there is this new security feature in android 4.2. that makes the device show a popup if you want to allow the connected computer to use the adb = debugging bridge. But for this to work, you need to have the newest adb binary, which needs to print 1.0.31 when you run "adb version"
(found that info here --> http://www.androidpolice.com/2013/0...s-from-stealing-your-data-in-some-situations/ )
Under linux when you try to do it the old-school google-recommended way and download the huge "adt-bundle-linux-x86_64-20130219" and use the "android" tool to find new updates to the platform tools, it will tell you you already got the latest version which is rev 16.0.2 which contains an adb binary which will print version 1.0.26 which will not work with this new android 4.2.2 security feature.
So after searching for a linux adb 1.0.31 binary, I found it here:
https://github.com/mozilla/r2d2b2g/commit/2eefcc05366173ca51635da8f542fd8473ba0fea -->
https://ftp.mozilla.org/pub/mozilla.org/labs/r2d2b2g/adb-1.0.31-linux.zip
with that binary I finally can use adb on my nexus 7 again.

[Q] Bricked phone, any way to fix it?

I installed deodexed 4.2.2 stock when i was running deodexed 4.2.1 stock. i felt that it was buggy, so i went into cwrecovery and wiped it and i was about to begin reinstalling deodexed 4.2.2 again when i noticed i forgot to put it onto my phone. then i tried to use my phone, and it would be stuck at "unfortunately, system ui has stopped". it never leaves that popup, so i can't enable usb debugging. i can't use recovery mode, because when i do, the android with a triangle caution sign is there, but no options to select from. i can enter fastboot mode, but that's about it.

Reflash a factory image in fastboot, flash CWM/TWRP in fastboot, reroot and reflash the dedexed rom. Your phone isn`t even a bit bricked fortunately.

Everything will be lost. Considering your phone is bricked there is no way to pull the pictures from your device.
Edit: you might not have to flash full stock, just the system.img that will allow you to overwrite the current system and maintain your sdcard.

i do not know if this is the best place to post this considering i am brand new (i hope so) but i have a soft bricked nexus s 4g that i am trying to fix.
it was loaded with the helly bean 4.2.2 custom rom from nexus hacks (sorry no links) after the reboot it went to a black screen.
what ive tried:
odin: flashing a new rom, this resulted in odin not finding the device (usb debugging is not on and i cant turn it on)
fastboot: (i have all the files but i cant seem to get it set up, i type in adb or fastboot (no device recognized)
nexus root toolkit: (wouldnt find the device and found no options to help with usb debugging)
dfs: (couldnt read the device)
plugging in the phone to the computer: it makes the noise that it is plugged in, comes up as f drive but it is greyed out and i cant click on it (says insert disc)
clock work recovery: i did a full data wipe and required wipes cache and delvik or something along those lines: it reboots into the rom and nothing has changed.. my guess is because there is no back up of the original rom and the cfw is trash, it just wipes the bad rom back to factory and that is still a problem.
pda net: wont recognize the device
galaxy nexus toolkit: nothing useful since the usb debugging is not enabled.
ive worked for 6 hours as of last night to figure this out. i have spent most of those hours in forums and delving further into this phone then id imagined (its not mine) so if there is anyone out there that can suggest anything id appreciate it. this has got me stumped and amazed how such easy fix can really be this complicated.. i will thank any and all answers given to me

You need to be in the bootloader for fastboot to work. Reboot to bootloader and try flashing a recovery.img using this command.
fasboot flash recovery recovery.img

ran sdk tools tried adb shell and nothing it wont read the device. we tried to push the .tar files to the phone using samsung galaxy nexus tool kit. it didnt work so hes going to take it to a repair but i think the device is toast on the account that usb debugging mode is no where in sight. if it does get fixed ill be sure to report how it got fixed. so anyone else who runs into the problem can get this fixed without a 20 dollar repair bill.

Unlocking the Nexus 7 (2013) Bootloader

This is the same as any other Nexus device.
WARNING. As is normally the case, this WILL factory reset your device.
Install the Android SDK (and Google USB driver).
Android SDK
Google USB Driver (Windows)
Enable USB debugging on the Nexus 7.
Unlock Developer Options by going to Settings > About Tablet and clicking on the build number seven times.
Go to Settings > Developer Options and check USB debugging. Click OK on the warning.
Connect the Nexus 7 via USB and reboot the Nexus 7 into the bootloader.
Note: Users have reported failures and "Access is Denied" errors when connected via USB 3.0 ports so use USB 1.1 or 2.0 to be on the safe side.
Open a command line / terminal and navigate to your SDK platform-tools directory.
Enter
Code:
adb reboot bootloader
and hit enter.
Once the Nexus 7 boots to the bootloader, unlock it
At the command line / terminal enter
Code:
fastboot oem unlock
and press enter.
On the Nexus 7, use the volume up button to select 'Yes' on the 'Unlock bootloader?' screen.
Press the power button to save your choice and verify on the next screen that you see 'LOCK STATE - UNLOCKED' at the bottom.
Use your volume keys to select 'Start' and click the power button to factory reset and reboot.
Enjoy your unlocked bootloader!

Do you have the usb drivers installed? That happened to me ("old" n7) when I didn't have the usb drivers installed.

may need to update your drivers for it to be able to see the device.
when you try adb devices while it is on does it kick back the device id number?
i haven't tried yet as i knew the drivers out currently would be an issue.

Perhaps it needs new adb/fastboot drivers ? I'm still charging mine, so I haven't tried. Sorry. Maybe the new driver comes with the 4.3 SDK ?

First off (don't mean to be a d!ck) but this thread belongs in "General", or "Q&A", because you haven't posted a development thread.
Second, unlocking the boot loader is just as easy as the first Gen Nex7. I had mine unlocked within 5 minutes of getting it home.
As others have said, make sure your drivers are installed, or ADB won't even recognize the device.

I updated my SDK when 4.3 dropped but I did have to go snag the Google USB driver and install it to get the N7 to be recognized.

1. You may be right (as far as my posts go) but how am I to ever make a dev post if I'm not allowed to make a first post in a dev forum?
2. This /is/ a dev-related post.
3. My feelings wouldn't be hurt if the mods felt the need to move the post.

Yeah I had to install the google usb drivers from the SDK in device manager of Windows to get the n7 recognized.

Thanx. Just got home with my new nexus 7....bootloader now unlocked :highfive:

Make sure you update your files from the SDK Manager. It had updated USB driver which from there it would install the proper drive and then it worked form me.

The trick, as stated in the Nexus Toolkit after driver install, is that you need to change the tablets usb settings from MTP to PTP. Tablet was immediately seen using "old" nexus toolkit universal usb drivers (old = i did not download the new SDK). I choose toro 4.2.2 (because it doesn't matter for unlocking) and then told it to unlock. worked like a charm.
Now the question is ... how long does it take to reboot cause mine is taking forever!!!
OK it booted. So yeah the Nexus 7 Toolkit ver 5.0 worked just fine to at least unlock. I did not root (4.3 still too buggy) or install a custom recovery yet.

Stock recovery, pretty please?
My dumbass flashed TWRP for Grouper. Wouldn't boot, so I tried erasing the recovery in hopes it would self-restore. No dice. Can't seem to find recovery-from-boot.p either. No boot and still no custom recovery for this puppy. :crying:
Would someone be the kindest person on earth and pull & post the stock recovery...or tell me how to find and flash a back-up copy already stored on my nexus? Google hasn't even posted the img files yet. My new toy is borked and Daddy wants to play tonight!
Thank you!

My body and my 7 are ready for a recovery!
Thank you!

I'd be happy to, but am having a hard time finding the correct ADB command.

isnt the new N7 files called Razor instead of grouper ? or is that just what the device was called prior to launch

adb pull

Help! Boot loop

Hi, I have a fully stock nexus 7 1st gen which is stuck on a boot loop, I am able to get it into fast boot mode where I've tried the wipe data/factory reset and wipe cache partition but it just freezes. I've searched around for solutions I've even tried flashing the stock images with wugfresh toolkit with no luck, most fixes it seems need the debugging enabled on the device which I can't do because I can't get into the menu. If anyone can help me it would be fantastic

Hey Mike, it sounds like you have no other option than to restore back to factory using the official Google Factory Images. That will completely wipe your N7, SDCard and all
Go ahead and download the nakasi image of your choice from Google: https://developers.google.com/android/nexus/images#nakasi... make sure that you don't accidentally get the nakasig firmware as it is for the Tilapia 3G model.
Extract it with 7-zip or WinRar (or whatever) and with your tablet plugged in and in Fastboot Mode, (you will also need the fastboot/ADB drivers installed) run the flash-all.bat batch file. (You may need to enable the Windows function "Show File Extensions" to see the .bat part after the file name. There is also a flash-all.sh in the folder as well but that one is for Linux users so you wont be able to use it unless you're on Linux.
Good Luck! :good:

Hi Tim, Thanks for replying,
I'm not too worried about losing data I'm just desperate to get it working again.
I have downloaded the flash image but where would I find the download for the fast boot drivers?

They should be included in the Wugfresh Toolkit that you downloaded. Just follow the steps to install the device drivers and I believe that the Fastboot drivers installs with it.

How weird, I am fixing my Dad's tonight, exact same issue! Have had it a week or so but just found time to do it now... I will do with you if you like. I already downloaded the wugfresh NRT and worked through the steps, obviously missing out the debug mode parts. Currently downloading the nakasi kot49h which is taking a while, so came on here to see what to do if this fails and saw your post!

If you download the nexus root kit v1.8.2 from www.wugfresh.com follow the steps on there to uninstall various drivers, then click the initial setup - full driver installation to get the correct driver for your device.

In the wug toolkit when installing drivers step by step guide to configure MTP drivers you need to disable USB debugging then disable MTP mode then re enable debugging all of which I can't do because I can't get into the menu to do anything

Hi Tom,
I can't seem to figure it out ive tried the wug toolkit a number of time with no results it seems most fixes need you to be able to enable debugging, if you find out how to do it let me know and if I by some miracle get it working I'll let you know

I have just run the flash stock and unroot option on wugfresh in the log everything has been erased but when it has tried to send bootloader is says failed<remote: bootloader is locked.>

Yes, you are up to where I got to. I fixed mine last night eventually. Next I tried a risky extra step which I won't tell as I don't think it did anything, then directly on the left of Flash and unroot there is a button to unlock bootloader. Run that, it gave me an error message but appeared to do the trick because the next time I ran flash + unroot it worked finally. Let us know how you get on!

No it still isn't working everything I try doesn't work it all comes down to the locked bootloader and no matter what I do I can't find a solution to open it
Has anyone come across the same problem and found a solution?

Open a command prompt in the folder with Fastboot. Type in "fastboot oem unlock" without quotes. That will unlock the bootloader and also you to flash factory image.

Doesn't work I've tried it before it just comes up with unlock bootloader screen where you have a choice yes (may void warranty) or no I click yes then I am directed back to fastboot mode with a message at the top left corner saying unlocking now....... but nothing ever happens, I restart device and I'm back to where I started.
Someone must know how to fix this

[Q][Answered] Have I screwed up? (Fastboot not seeing the Tablet)

Okay, I bought a Nexus 10 off someone, and they had already rooted the device. Bootloader is unlocked and whatnot. That's where my problems start. I can not for the life of me get fastboot or adb to see this thing.
Here's my info:
Google Nexus 10 (Samsung)
ClockworkMod Recovery 6.0.4.3
Bootloader Version: MANTALJ12a
Windows 8.1 Pro x64
Full Android SDK
Samsung drivers installed (I rooted my Galaxy Nexus without issue).
USB has a direct connection
Before I decided to format and try to install a stock .zip, I could access the tablet as a media (That's how I got the .zip on the device).
Steps to how I got here:
Flashed Cyanogenmod 10.2 or whatever. Didn't want JB, wanted Lollipop.
Pushed the (what I thought was correct) .zip to /sdcard
Booted into recovery
Formatted /system, /cache, /data, /factory
Reflashed the .zip
Failed. Miserably.
I named the .zip as something simple and just overwrote it. I wouldn't have this issue if it wasn't for that. I know I did a bad there.
But still, nothing I can do will get fastboot/adb to see the device. It makes the sounds that it's connected when I plug it in. I'm using an elevated prompt as well, but it will not pull the device. How do I get myself out of this hole? If I could push a new .zip to somewhere on /sdcard I could at least use the recovery to reflash.

Wrong device ? [emoji14]

No, I was going to put it in the general help thread, may be better here since this may not be a simple question (Please prove me wrong).

Some additional things I've tried:
The NExus Root Toolkit. Removing all drivers etc. Still getting to fastboot by PWR+ VOL+ + VOL-.
Still nothing. Should I go to my wife's computer and try it there? I might do that anyways.

You don't have access to have os then? How did you push your zip if you don't have access to adb?
I have seen people who couldn't get adb and fastboot working on their windows and switching to another computer solved the issues.
Ok, make sure to make a full clean of your drivers. Wug toolkit explain how to. Then install proper samsung driver and this
If it is not a hardware's problem, you should have access to fastboot & adb. You might try on another computer if possible. A clean one would be the best (i.e. never used any droid devices, etc.).
Another workaround would be to use and otg cable and an usb drive with any zip of your liking.
Another one, I had an issue long time ago, similar, I had to flash through odin in downloading mode to fix my problems.
BUT did you really deleted /factory partition? It contains various proprietary files needed for the device to work. Well concerns more devices with imei and stuff to allow 3g connection and co. Might have no incidence tho on your device's behavior.

Sorry if I wasn't clear on this, I have 100% access to my computer. I have the Android SDK installed, and adb/fastboot commands working in command prompt. They're just not seeing the tablet.

Yeah, seems to be doing the same on my wife's computer (Win 7 HP, never had my phone/tablet hooked to it). I get adb/fastboot loaded and working in the command prompt, and it registers when I plug in, but neither command will "see" the tablet.

It's a Wifi tablet, no cellular data and IMEI etc.
edit: As a side note, I've been thinking about reformatting my computer, though it'll be a huge pain to get it back to here as I've got to go from 7 - 8.0 - 8.1 on the upgrade paths to get it back here again.

From my own experience, having similar issue with the windows drivers for adb, but eventually I fixed it. I really doubt you are screwed.
adb version output ? 1.0.32 is latest.

Installed universal adb drivers? Nothing shows up in the device manager?

You might try odin.
Usb mtp doesn’t work from recovery?

Android Debug Bridge version 1.0.32, yep latest.
I just feel like I'm missing something, maybe something stupid. HOWEVER, I'm now getting my nexus 10 to show up in device manager with a ? on it. Already tried the direct Samsung drivers, the universal drivers in the Wug toolkit.

Did you deleted all samsung vendor, etc from the usb program, you know what i am talking about?
You can force to install drivers from device maanger, don't remember how, when installing manually, you must do some step , install from floppy or file, get inf files or so, you will get a prompt telling you it might be harmfull and it will force installation. Might be the solution?
The culprit is definitely software-sided.
Does the mount internal storage (mtp) work?

Would this be easier in Linux? I could pop open my Ubuntu VM and do this if it'd be easier?
Beyond that, are you telling me to try and install the drivers from the driver files created by the Samsung vendor .exe?
I have tried to 'mount USB storage' from recovery, but it doesn't seem to do anything. /system /cache /data /factory are all mounted ATM and nothing is showing.

You've already got more advanced advice than I can offer but when I tried to update to 5.0.1 from 4.4.4, I couldn't get my windows computer to see my device. I was trying the adb fastboot but it I couldn't get it to work.
Wug's toolkit got it all straightened out (http://forum.xda-developers.com/showthread.php?t=2015467)[*]. There was an option on his interface that asked whether the device was working properly or not (a!most missed it as a choice). Checked that box and it went through much of the process I had done (installing adb, updating drivers etc). Long story short, it worked.

Where did you see this option? The only thing I see is the Soft Brick/Bootloop option where it will install the factory again. Was it that or somewhere else?
I swear to the Android droid that I tried that before. That seems to be doing what needs to be done, holy crap thanks!
e: I would like to know, however, why fastboot/adp wouldn't work but this would without doing any of the other stuff?

You're right. I confused the heading but choosing that option got my computer and my Nexus "talking." After installing the factory image I think you can then push a cusom ROM to you Nexus (http://forums.androidcentral.com/go...acks/264619-wugs-nexus-toolkit-questions.html).

Problem solved ? I always had less issues with fastboot and adb on Linux you can install a ppa that install for you adb and fastboot
Hovewer if you are using 2.8.2.0 you will need 1.0.32 and the ppa includes 1.0.31 so only adb sideload fails.
