Confused, does the toolkit say your drivers are correctly installed.

If they aren't, I think you can get the drivers pretty easily using PDAnet.

Not sure if this will help, but this is how I rooted my stock 4.1.2 nexus 7.

1) Opened toolkit (I ran it as admin and disabled my antivirus stuff for safety)

2) Select your model - this should be NAKASI: Android 4.1.2 Build JZ054K (Jelly Bean)

3) Click unlock and follow the prompts. It will tell you when you need to plug in the Nexus 7 from memory. Remember that it will need you to be in fast boot. To get to fast boot, power off the device and power it on holding the power + volume up + volume down.

4) When the unlocking process is done click root

If this doesn't work, others have recommended flashing an older version of the bootloader. I didn't have to do this, so I'm probably not the best to comment. Wug uploaded some detailed instructions though: http://xdaforums.com/showpost.php?p=32789382&postcount=1199

Best of luck

holy crap, damn ! . i've been going around and around for 12 hours straight ! ! ! . and then i find out the boot loader 3.41 is gaa gaa for the process... and you have to back step it to 3.34 to get any where...

.

damn.

.

a note at the top ( the O.P. ) would have been REALLY nice...
[Nexus 7 Android Development] talltexan:
Thanks in my frustration i forgot to point out what i have done. I have successfully unlocked the fasatboot (wipes your memory DOH!) I was able to do that the first day i got it. When i am saying that the drivers are installed correctly, i run Wugs "drivers test" and i get a successful message at the end. I will try Wug's older bootloader and see if i have any success with that.

***Edit***

Meant for Nexus S, I didn't realize I was in the wrong forum

Just tried to restore to stock using this and it failed. Apparently the stock image isn't available, hashcheck mismatch, extraction- will not flash! and flashing stock was canceled, tried the "download manually" and the page comes up as an error. I suspect this isn't updated? Is there a better toolkit available? Thanks in advance!

***EDIT***

I can figure it out, just realized I am in the wrong device section lol. I am using this for the Nexus S so I will try manually.
[Nexus 7 Android Development] WugFresh:
? I suspect that you are on a bad internet connection. You can download the factory image packages from Google if the downloader isn't working for you.

Google Code - Factory Image Packages

I can assure it works. What do you mean the page comes up as an error?

[Nexus 7 Android Development] talltexan:
BOOM that worked !!!!!!!!! Thanks WUG you are awesome sauce.

*edit* now the question is AOKP or CM10? Love me some AOKP goodness and because the JB kernel is out we shouldn't experience the same issues that i have on the SGS II
[Nexus 7 Android Development] WugFresh:
Sorry about that. I included a note in the OP now.

I rebooted my Nexus 7 to bootloader mode and I see I am running bootloader 3.34. Might I ask a few related - hopefully quick - questions?

1. My guess is people with 3.41 bootloader have it because they bought a newer revision of the Nexus than mine or performed an OTA update. Is this assumption right?

2. I'm running a custom ROM. Is there any reason I should want or need to do the OTA update? Cropped screenshot attached.

3. Should I care about upgrading my bootloader? If the "cold boot, untethered recovery" problem was fixed I might. OK maybe that is two questions. I don't even know if the cold boot problem relates to the bootloader.

4. Any way for somebody to check his bootloader version without going into bootloader mode? It is a bit of a pain especially because of the reboot hang.

Thanks for reading.
[Nexus 7 Android Development] mullemulle86:
1. I have a newer bootloader because i flashed it

2. If you are running a custom rom there is no need to flash the ota

3. Yes if you want to cold boot into the recovery

4. i dont know another way

Here is the new bootloader http://db.tt/RaOf7zj9

[Nexus 7 Android Development] danny8:
Thanks! Blown away by the fast response.

And thanks for the link! I feel a little ashamed for not having to expend more effort.

Yes, I will upgrade my bootloader then.

I'll be mindful to watch for problems alluded to by Wug and others. (Not sure I fully understand those, but I'll reread the relevant posts.)

Update: I flashed the new bootloader and it works fine. Cold booting into the bootloader ->TWRP works now.
[Nexus 7 Android Development] amadablam:
Ive made a mistake, my own fault too.

Used to being able to select the file off any drive or folder when flashing on my S2, I never put the ROM on root of Nexus7

Now using this kit, I dont have fastboot or ADB regardless of what I do.

I can get to Google screen or boot into ROOT screen but no recovery will install

If anyone can help me, it would be great, thank you.

Cant do anything without fast boot.
[Nexus 7 Android Development] talltexan:
I've never flashed a ROM on this one. Can we not just flash cwm then boot into recovery and find the file?
[Nexus 7 Android Development] WugFresh:
Yeah. Except to cold boot into recovery, your device needs to be connected via usb if your are on the older bootloader. You can use an app like QuickBoot to boot into recovery though, or the toolkits "Reboot Recovery" button in advanced utilities "Quick Tools". The flash zips utility (with "on my computer" selected) in the toolkit essentially does the same thing, it pushes zips to your device and then uses recovery to flash them... the only difference is that its automated and allows you to perform other tasks all in one go.. like perform backups first, or wipe, etc. Its designed to streamline the process. But doing it in recovery yourself is still a great way to do it.

{{ WugFresh }}
[Nexus 7 Android Development] WugFresh:
I am sorry, but I honestly don't understand anything you are saying. Can you try describing your problem again? Maybe try stating what your goal is, what went wrong, and what you tried. I am just really confused by what you wrote...

Sounds like you never configured your drivers? Like you are having problems having the toolkit recognize your device? If that is your problem, please try using the driver guide, I provided as much information as I possibly could in that.

{{ WugFresh }}
[Nexus 7 Android Development] talltexan:
Good deal so if I use cwm to boot into recovery as long as I wipe and flash like on my sgs II I'll be fine. Your saying fast boot is another hurdle that won't let you access a custom boot loader like on other phones?

BTW thanks for the quick responds I can see you take pride in your work.
[Nexus 7 Android Development] WugFresh:
Yes.

No.. I have no idea what you mean by that. What I am saying is that the older bootloader (on 4.1.1 builds on the Nexus 7) makes it impossible to boot into recovery from a cold boot. By that I mean, holding the volume buttons and power button to get into bootloader mode, then selecting "Recovery" - the device will just boot up, even if you have cwm or twrp flashed. The only way to get into recovery successfully on a Nexus7 using the old bootloader is to do the same process I just mention but with the device connected via usb (for some random reason this works), or using the toolkits "reboot to recovery" button, or using an app on the device like QuickBoot or ROM manager.. or any app that can reboot your device into custom recovery. The new bootloader in version 4.1.2 seems to fix this cold boot problem, but for some it makes "fastboot boot" commands not work, which is why some people were having problems rooting this build with my toolkit unless they reverted back to the old bootloader.

{{ WugFresh }}
[Nexus 7 Android Development] talltexan:
People like me lol! Cool sounds good. Sorry for pestering with questions but do you have a link to the 4.1.2 boot loader so I can upgrade back to it now that I have root access?
[Nexus 7 Android Development] WugFresh:

I just rooted my wife's Nexus 7 and all went well, seemingly. Booted into recovery and flashed a CM10 rom and I keep getting a bootloop of the CM10 boot animation. The toolkit is unresponsive and I can't boot into recovery. Can anyone help?

Flashed this version of CM10 which is the same one on my tablet.
[Nexus 7 Android Development] WugFresh:
"Flash Stock + Unroot" with "Can't boot up" will walk you through restoring your device. It will wipe data though, so hopefully you made a backup. You may also be able to avoid doing all that by just wiping data if you can get into recovery.

[Nexus 7 Android Development] m4rk0358:
Can't get it to reboot into recovery. Where do I get the latest Odin?

EDIT: Wait, isn't OdIn only for samsung devices?
[Nexus 7 Android Development] WugFresh:
ODIN is for Samsung devices only (as far as I know). There is no ODIN/Download mode on the Asus Nexus 7. To get into recovery from a bootloop, you are going to need to battery pull first. Put the battery back in.. then follow the instructions. You need to get your device into bootloader mode to use the "Flash Stock + Unroot" with Can't boot up option.

[Nexus 7 Android Development] m4rk0358:
How do you pull a battery on a nexus 7? It's not removable.
[Nexus 7 Android Development] WugFresh:
Oh.. sorry. I have a Gnex. Ignore my comment. I guess you have to try holding down the power button, or just waiting for it to die.

{{ WugFresh }}
[Nexus 7 Android Development] m4rk0358:
Looks like I'm going to have to wait for it to die, Once it does, do I try holding down power and both volume buttons?
[Nexus 7 Android Development] mullemulle86:
You can pull the battery.

The back is removeable and the battery too

Gesendet von meinem Galaxy Nexus mit Tapatalk 2
[Nexus 7 Android Development] danny8:
On the Nexus 7, you should be able to stop the bootloop by very-long-pressing the power key. About fifteen seconds or longer. That should turn off the tablet.

On a normally functioning Nexus 7 you should be able to start bootloader mode by holding volume down right after you start the tablet. From bootloader mode you have several choices.

(Others have already mentioned 'cold booting' bug with the older bootloader. If they're going to happen, you'll see them when you try to proceed from the bootloader into CWM or TWRP.)
[Nexus 7 Android Development] Pariah3000:
WugFresh's tool kit to the rescue again! :good:

I had been having more than a little trouble updating to 4.1.2 as I deleted some system apps and made changes to my build.prop and had been trying different kernels before the update. All in all I was screwed. Nothing WugFresh's tool kit couldn't fix. I used the kit to flash back to stock, got the OTA update and then used the tool kit to reroot my Nexus 7. I'm just using Titanium Back up to restore my apps now. All in all Wug's tool kit was a life saver. Thanks a lot!
[Nexus 7 Android Development] m4rk0358:
I'm at a loss now. Was able to boot into fastboot and then used the toolkit to unroot and bring back to stock, now as 4.1.1. Went through the root process again and everything appeared to work smoothly. I went ahead and updated superuser and busybox. I then flashed clockworkmod thinking maybe there was something up with TWRP when flashing CM10 and again i got into an endless bootloop of the CM10 boot animation. I'm running out of ideas. :(
[Nexus 7 Android Development] danny8:
The fact that you got into the bootloader and restored back to stock is a very positive step. When you say you returned to stock did you successfully boot your tablet? Are you able to return to stock again?

Maybe I misunderstood a previous post of yours, but I had the impression you were unable to get to the bootloader. Was it just 'random' that you finally succeeded, or were you doing something incorrectly? Are you able to get to the bootloader reliably? Both with the ADB cable and without (using buttons)?

Sorry for the obvious questions. Just in case you overlooked something.

How did you resolve your bootloop? I hope you didn't have to let your battery run down.

I guess mullemulle is technically correct, the back is removable using a special soft prying tool. But I sure wouldn't want to do that; not until my battery wears out, anyway.

PS - As I read my post, I realize I use the term "bootloader" a lot. Not sure why I do that. Maybe I should say fastboot instead. I don't know which is preferable.
[Nexus 7 Android Development] m4rk0358:
I resolved the bootloop by letting the battery run down, gave it 30 minutes of charge, pressed power and then immediately held down volume down. This booted the tablet into fastboot/bootlader (I''m wondering if i could have done these steps without draining the battery?). I then used the toolkit to revert back to stock (was originally 4.1.2 and the new stock is 4.1.1). I then rooted via the toolkit and was able to successfully root the stock ROM. Finally, I re-downloaded the CM10 and GAPPS and tried flashing them via clockworkmod (obtained by downloading ROM Manager). Once again I got the CM10 boot animation continuously looping.

I'm at work now and cannot install the toolkit here so will have to wait until I get home.

Maybe I'll try flashing a different custom ROM and see what happens. Sounds like I'll have to revert to stock and re-root first.
[Nexus 7 Android Development] danny8:
I would have turned off my tablet using the very-long-press. Then I would have powered up and held volume-down to get to fastboot. (Ignoring for the moment the cold boot bug afflicting some of us.)

Also, not trying to be an a-hole, but you never explicitly said you booted into the full blown OS. I'm guessing you did, 'cause you spoke about updating busybox et al.

It sounds like you've got stuff to figure out, but your situation doesn't sound too bad compared to some folks who can't ever get to recovery mode.

Speaking of which, I like TWRP a lot. But it bugged me when Wug switched because I have CWM (not even the touch version) on my phone. I was feeling loyal to CWM. Now I wish my phone had TWRP on it. Nobody's ported it.

[Nexus 7 Android Development] m4rk0358:
Ah yes...I did boot into the full blown OS. Sorry for leaving that out.
[Nexus 7 Android Development] danny8:
I don't know if this affects you, but you might want to reread the OP. A guy on this forum was complaining that he wasted a lot if time because of this issue.

For all I know, I could have this problem (or maybe a problem like yours) when it comes time to reflash my ROM.

I updated my bootloader but I haven't used Wug's toolkit since that change. Heck, I'm still using 1.5.3 of the toolkit.

Note: when I updated my bootloader I did not use the toolkit. I simply downloaded the zip with my tablet and flashed the zip with TWRP.
[Nexus 7 Android Development] m4rk0358:
I'll try that when I get home.
[Nexus 7 Android Development] WugFresh:
Try again, except this time just flash CM10 without flashing GAPPS.. Let it boot up, then go back into recovery and flash GAPPS. I am like 97% confident that that is what is causing your device to bootloop. Try to avoid flashing multiple things in recovery in one go unless the instructions explicitly tell you too, or you know that it won't cause problems, like a small mod or additional user app.

{{ WugFresh }}
[Nexus 7 Android Development] m4rk0358:
Awesome...hopefully that works.
[Nexus 7 Android Development] Doritos Bandito:
Is there a way to actually uninstall the program from the computer? I dont see away unless I just delete the folders.
[Nexus 7 Android Development] WugFresh:
I included an uninstaller in the toolkits directory: Uninstall_NRT.exe

That will uninstall everything except your nexusbackup folder. All the files are contained locally within the install directory, so deleting the folders would remove it, however if you use the file association options, you would wan't to uncheck those in options first - then uninstall. The uninstaller takes care of all of this:

- It force closes any instances of adb.exe and/or fastboot.exe running as well as the toolkit itself

- It makes sure all file associations are removed

- It deletes all the folders except for the nexusbackup folder

- It opens the nexusbackup folder in windows explorer - in case you want to go ahead and delete that too

- It deletes itself

If you are running an older versions of the toolkit that didn't have the uninstaller, you can either delete in manually in the way I described above, or just put the Uninstall_NRT.exe in the directory of the old toolkit and run it. It will work on older versions of the toolkit.

I didn't have the application add itself to the add/remove programs to avoid dealing with windows signatures/certificates and all that. I didn't want my program to flagged by AV programs. A few files were flagged in early releases of my program anyway by some AV programs but I have been in contact with Avira, Bitdefender, and a few other companies and they have apologized and removed the false positives from their database.

Wug, i tried to extract the bootloader but only got 3.41 and the one you gave me was the same. I have tried to google for 4.1.1 CWM wont let me reboot into recovery for some reason :-/ Any help would be appreciated!
[Nexus 7 Android Development] WugFresh:
Let me be as clear and explicit as possible here because I am getting frustrated repeating myself about the bootloader.

For many end users the new bootloader in android 4.1.2 JZO54K [bootloader-grouper-3.41.img] works without any issues and resolves the cold boot issue (being able to successfully boot into alternate recovery from bootloader mode without the device being attached via usb).

However, for some - the new bootloader prevents "fastboot boot" commands from working properly, so the end user may experience issues using the toolkit features (or doing these commands manually) until they revert to the older bootloader from android 4.1.1 JRO03D/JRO03C [bootloader-grouper-3.34.img]

This older bootloader is linked in the OP along with instructions on how to flash it.

________________________

Now to clarify your comments.

Our conversation started with you saying this:

You explicitly asked me to link you to the NEW bootloader from 4.1.2. I responded with a link, and also stated that you can get it from googles factory image package on their site [i.e. I told you two ways to get the same file]:

Now you stated this:

Yeah. The one I gave you was the same because that is the one you explicitly asked for. If you want the 3.34 version (the older one) rather than the new one, which is the one you asked for. Then download it from the OP:

I really hope that clarifies things. Please read the OP, and re-read your own questions.

________________

On another note. I archived ALL of the nexus factory image packages on Goo.im here: http://goo.im/devs/WugFresh/stock so if anyone needs an older package or file you can grab it. I will do my best to keep that archive updated whenever new factory image packages or ODIN packages come out for any of the Nexus devices.

Cheers.

[Nexus 7 Android Development] m4rk0358:
Dang. No luck.
[Nexus 7 Android Development] WugFresh:
Please elaborate. Also.. to be clear, did you re-download CM, and hashcheck to ensure the files integrity. Did it bootloop without flashing gapps. It's impossible to diagnose a problem with no specifics.

{{ WugFresh }}
[Nexus 7 Android Development] m4rk0358:
I reverted to stock. Re-rooted. Downloaded CM again. Flashed it without flashing GAPPS. Boot animation bootloop.

Okay. Well this is getting entirely off topic regarding the toolkit. I am happy to help you with this issue, but lets do it off this thread. Hit me up on gchat or send me a PM. Wugfresh at gmail. There are other troubleshooting options that can be exhausted.

[Nexus 7 Android Development] talltexan:
Wug sorry if I Miss understood you. I did use the 3.41 to be able to root. Now I'm looking at upgrading the fast boot to the latest so I can cold start a recovery like cwm. Sorry this nexus is so different than any phone I've used before so there is quite the learning curve.
[Nexus 7 Android Development] WugFresh:
The 3.41 is the NEWEST AND LATEST bootloader. Please read. I am sorry but I really can't be anymore explicit in this regard.

3.34 = OLD

3.41 = NEW

You are trying to upgrade, but you are on the latest bootloader. I now have linked you to both the new and old. If you are still having problems cold booting with the new bootloader, than I am not sure why. I haven't heard that problem yet, but based on what you have said.. my guess is that you haven't tried yet.

{{ WugFresh }}
[Nexus 7 Android Development] talltexan:
Once again thanks for putting up with pestering questions. If you don't mind maybe I

Could hit you up on gchat tomorrow. I am on 3.41 whenever I try and boot into recovery from there the n7 reboots to the normal OS. I tried flashing using your tool and it pushed the files visited into fast boot then reboots without flashing. I have tried rebooting to recovery from the app but no luck. I did reboot once into cmw but haven't been able to replicate that since the initial installation.
[Nexus 7 Android Development] pughie:
@talltexan it appears that your n7 operates the same way as mine, in that no matter what I try, as soon as I install boatloader 3.41 I can't get into recovery either via an app, the nrt or via adb, the answer is to install bootloader 3.34 as it allows me to get into recovery via the nrt or via adb or via an app, I have flashed a number of ROMs since down grading my bootloader without an issue...there is actually a seperate thread about the new bootloader I would suggest reading that as the issue has nothing to do with wugs toolkit which works as it should
[Nexus 7 Android Development] danny8:
I wasn't planning on re-flashing my N7 for a while. But I'm going to flash later today, just to see if my tablet is susceptible to these (hopefully rare) 3.41 bootloader problems.

27-Oct Update: No problems flashing N7 tablet. Used Wug's Nexus Root Toolkit to install a new custom ROM. Tablet has new bootloader; cold booting works, flashing works.
[Nexus 7 Android Development] talltexan:
Pughie, now that i think about it i was on the 3.34 bootloader whenever i installed CWM... I will try that thanks. Just damn frustrating as i have never had a phone be difficult like this.
[Nexus 7 Android Development] truthkillszz:
Sorry if this has been mentioned but I am on the 3.34 bootloader and while i was rebooting from flashing a new rom my n7 got stuck on bootloop I tried manually booting into recovery and that bootlooped also. Now I can not boot up into anything but bootloader but once I plus my tab into the pc the bootloader freezes up but your app still recognizes it. So i Figured I should try unrooting and flashing stock but it flashes all the way up to system and then freezes. it has been 'sending' to system for over 15 min now.

I just tried even temp booting into a custom recovery and your app says everything was ok but my device is still stuck on bootloader.
