Help! Need to unroot + lock bootloader without USB

So my nexus won't charge unless its off.. and it won't connect to my computer either. I can't send it in to Sam's club (or can i?) if its rooted. I needdddddd some major help figuring out some way i can replace it... a way to unroot + lock the bootloader. Please? anyoneeeee? By the way... i have no idea how to use adb and stuff because i used a one-click script :/

Things like this is where I really hate how there are one click scripts.
If you aren't knowledgeable about what the tool is doing, don't do it.
Since its probably easier for you to just use another one click tool, use Wug Fresh's one click and use "Return to Stock"
Please, for the love of god, don't do this to your device if you don't know what you are doing.

He said he can't connect to his PC (broken USB port, I guess).
You may be able to unroot it, but you probably cannot lock the bootloader without USB. Sorry, I don't know of a way to.

OP, you could at least do a Factory data reset under Backup & reset in Settings. I doubt that that would lock and unroot the device, but I don't think Sam's Club would really care.

Is it because you need someone to set up the drivers and get ADB working on your computer?
Is your device recognized at all when you connect it to a computer?

You can probably try to factory reset, if you haven't flashed other ROMs.
Also, if you flashed ClockWork Mod bootloaders, Google how to root HTC One X.

I have adb set up... just no idea how to use it. No, it isnt.

I did factory reset... to no avail...

1. Did you install a custom Kernel or ROM?
2. Your computer doesn't even make any sort of "ding" sound when you plug the tablet in? How about if you slowly wiggle the cable around in the tablet?

Well if you managed to root your tablet using a toolkit then you're computer must have a functioning port. the toolkit probably has a return to stock option so run it. Factory/data resets will only wrote the data partition but will not touch system/bootloader. You will need access to a computer in order to fully return to stock with the bootloader locked.

Nope, it was running stock. Nope! It works if the device is OFF though.

How did you root it if your PC doesn't recognize it. Make sure adb is enabled in dev options. Also try typing "adb devices" in your computer after you have adb setup. If it doesn't work get the universal drivers from the dev section and reinstall the drivers.

Boot into the bootloader (Power+Volume down), does your computer detect anything at all?
Any unknown devices or familiar device names in "Device manager"?
Edit: It might be Volume up and down with power... Don't remember.... I always use ADB to go into the bootloader.

You had it right, volume down+power=bootloader.
Like a couple people said..you used a computer to get in you can use it to get out. I've pretty much screwed and unscrewed just about everything on this tablet..probably been in the same situation here too. Its a nexus device, I'd actually be impressed if you did something not easily fixable. Maybe a little more thorough explanation of exactly what you have done so far, how you've done it, and what you've done it with. Paint us a picture. Should be a very simple fix. Small details can make a huge difference.

I believe he is having the same problem that I am. It worked fine at one point(mine worked fine for two weeks), then something happened and now the usb port does not work while powered on. I cannot charge it or connect to a computer via usb while powered up. If i turn off the tablet, I can charge it. I have tried multiple cables/chargers with the same results. Originally I was able to connect via ADB to my computer with this tablet, but cannot anymore. Also, I swapped the usb port hardware out of my nexus 7 with my wife's nexus 7 to see if it was the plug. Same result. The port from my tablet works just fine in hers, but hers does not work in mine. I'm not sure what happened, but I cannot unroot/lock the device without the USB so I cannot return it. Very depressing.

Have you tried WugFresh's toolkit? There's a flash stock + unroot with a “can't boot up" option. Then you can relock the bootloader.

Does it require USB access?

Yea but not adb. Might even be able to start with tablet off. Not sure if either will work but its an easy start. You've used fastboot before right? It's easy. The toolkit thread will walk you through a couple simple steps. Again, don't get your hopes up it's just an easy start.

USB Device Not Recognized.

Hello, I was wondering if someone could help me. My computer no longer recognizes my tablet and says it is an unknown device when I connect it via USB. It won't detect it in odin either. I have the correct drivers installed and have tried reinstalling them and have tried it with different usb cords and different computers with the same result. USB debugging is enabled. I am not sure where to go from here. If someone could please point me in the right direction I would sincerely appreciate it. I would be able to restore functionality to be able to transfer files between my tablet and computer through USB once again.
ROM: BinDroid (Previous was CleanROM and had same issue)
If I download roms through tablet I can install them normally through CWM, and my tablet boots up okay so I am not really "bricked" But I am kind of bricked in the way that I can no longer use odin to flash anything..which is not very good.

am i the only one with this problem.....

No, it is one of the big problems when loading ROMs, bootloaders, etc. Most of the time it is better to fully de-install the driver and then reinstall, as the change of the ROM also changes the perceived device-id by USB (on Windows I presume). I have even seen this happen between HC Stock and ICS Stock...
Odd but true. So, try to de-install the driver (or Kies, including driver) and reinstall (Kies, or just driver). Most of the time that should be enough, but do not hold it against me if that did not solve it.

Here is a possible solution, disconnect device tab/phone, disable your firewall connect device, mine worked, disconnect again restart firewall reconnect device.
this worked for me and also with my s3.

I even tried it with a new computer that has not recognized the device before. I am afraid to use mobile odin as well and I can't backup all my stuff like my pictures and videos. I guess i could use upload to dropbox.

Root without USB

Hi,
I have a TF101 and a chinese USB data cable.
Whenever I connect data cable, the screen lights up to show it is charging alright. But the PC doesn't register a new device. I even checked the Device Manager.
Is there a way to root the device without USB connection (/PC)?
I have already placed Superuser flashable on the root folder but don't know how to flash it. I come from Samsung world, where it used to be pretty simple.
Thanks for listening.

There was one firmware version of HC that was, but that was from over a year ago.
Have you tried checking the USB Debugging in the DEV Options of settings to see if that allows it to be detected?
Otherwise you will need a computer to root.

I don't care how long ago it was. Can you please point me to direction if this - "HC".
I tried toggling "USB debugging" as well as "MTP/PTP". Nothing helped.

Sorry, HC = HoneyComb (Android 3.X).
Razorclaw worked to root the following devices on the indicated builds:
ASUS Transformer TF101 (8.6.5.19)
ASUS Transformer 3G TF101G (8.6.6.19)
ASUS Slider SL101 (8.6.5.18)
Asus never published any of these builds because of the security flaw.
If you are on a newer firmware (Android 4.0) I am not sure there is a good way to downgrade.

Samsung's stock recovery allowed flashing(update.zip). Isn't there a similar method for Asus?

Need some noob help with Rooting my N7

I'm insanely frustrated. My N7 was rooted. Suddenly now it's not.
Absolutely nothing is working properly. I tried installing the adt-bundle for Windows. It doesn't install. All I get is a quick DOS prompt flash, and nothing actually installs.
I tried installing the Sixaxis pair tool. That won't work, because I get this message: http://i.imgur.com/VU9Ou14.png
I tried running CF Root, it doesn't detect my N7.
I'm using Windows 8. I don't know if it's my PC, my N7, or me. Maybe all of the above? But for some reason nothing seems to want to work. The sheer volume of information on rooting my device is overwhelming. If anyone can give me a hand, it would be greatly appreciated.
End result for me, is I just want to use my PS3 controller with my N7. It's not even working with a hard wired connection for some reason.

Do you still have a custom recovery installed?

I don't see anything in your post that says which rom you're using, also if you double clicked on something like adb or fastboot.exe you're doing it wrong, course it'll just immediately close, you have to run it from cmd.
Please go read some of the stickied posts because it seems like you haven't grasped the concept of using adb/fastboot and the problem is likely easily fixed if you just read the instructions instead of relying solely on tool kits.

I'm not using a rom, nor did I ever install a recovery. All I needed to do in order to use my PS3 controller wirelessly, was to root the device. That's all I need to do.

Is it not completely ****ed up that I get these two messages? My PC clearly shows that the ADB drivers are properly installed. However any kind of rooting tool I use does not detect my N7. USB debugging is selected on my tablet. I just don't get it.

Need root without computer, bootloader unlocked...

I have checked at least hundred threads now, but my problem seems unique! (First time this happened to me )
When I connect my N7 (WiFi, 32 GB) to my laptop (Win 8.1), it says "USB device not recognized - The last USB device you connected to this computer malfunctioned, and Windows does not recognize it." In Device Manager, it is like the image attached, no other recognition for the device. Upon selecting Properties, It says "Code 43" in status, also says "A request for the device descriptor failed". That happened with 2 computers; I used 2 cables (both worked previously). So it means N7's USB port is somehow malfunctioning. But it gets charged as well as ever!!
This started after I tried an OTA update of 4.4 earlier (the download had not completed, but a prior small update (1-3 MB) was installed).
Now, I have Android SDK (latest version) and installed those google USB driver and platform-tools. I have NRT 1.7.9 (which worked for me previously). But I cant get my N7 to answer to ADB requests. [highlight]Upon connecting USB, it says "Charging (USB)" but no option regarding PTP or MTP appears.[/highlight] I have developer tools installed. I followed the instructions given in NRT about ADB installation to the letter but still no progress. I have tried a factory reset too.
BTW, I dont have a custom recovery flashed. It vanished along with the precious root privilage.
Now the N7 is in Android 4.3 (JWR66Y), bootloader is unlocked, SuperSU is Installed (but do not work due to having no root access and I cant even Uninstall it for the same reasons!!!). Now the OTA update also do not work mysteriously (it downloaded the 4.4.2 update and went on to install it, but as the bar started filling, it only said "error" and stopped!!! no explanations whatsoever!!!!). I will be very happy any of the followings:
[highlight]1. root without computer (wireless ADB is also welcome),
2. working OTA, or anyhow the 4.4.2 update
3. working ADB connection with my laptop.[/highlight]
Any help will be very helpful... Thank you in advance...

If you can not communicate via USB hardware, then using fastboot is not an option (obviously). And so therefore the lock state of your bootloader is quite irrelevant, too.
Even if you were to get adb over tcp (WiFi) working, that doesn't get you much, as an adb login shell on a stock ROM is just an unprivileged user; it's not much different from using a terminal emulator app (from a privilege escalation point of view).
The only other thing left is an exploit (privilege escalation) method that runs under the stock ROM. Something similar to that Motochopper exploit from some time ago. I suppose that particular hole was plugged; whether or not a new exploit exists, I can't tell you.
You could always just send the tablet back for repair. Seems like not having a working USB port is pretty crippling to someone who wants to root, flash ROMs, copy backups off the tablet, etc.

Thank you for the replying...
Actually I lack warranty as I bought this from eBay weeks before it was officially available in India. Therefore I kept that repair thing as a last resort. I am now trying it through Linux. And being a noob there, its going too slow. However I have got the ADB working and detecting the device, so its not a port issue (I dont know why the hell windows was so adamant on that point!)... But I am yet to figure out how to flash the image... thank you for the tip over wi-fi, i was actually hoping to wait for it...

Well that is very different than having a broken USB port.
You probably noticed in your search that this forum is littered with thousands of reports from users complaining about their Windows drivers. It gets pretty old, frankly. (No drivers are needed at all for Linux or Mac OS/X).
Here is a suggestion that I made in another thread just a few days ago about using fastboot under Linux - in your case, you will be on your way after installing a recovery, e.g.
Code:
fastboot flash recovery openrecovery-twrp-2.6.3.1-grouper.img
I even attached the most recent version of the (Android SDK Linux) fastboot to that post.
Note that you don't even need a dual-boot PC or PC with a semi-permanent Linux install; you can do the whole thing with one of those "Live CD" boots and a USB stick.
good luck
