The problem is I can't unbrick and restore my nexus to stock rom.
I can't boot the device and I'm only able to boot to bootloader. However, my computer doesn't recognize the nexus. It keeps saying Window cannot recognize it whenever I plug my tablet to the computer in bootloader. I tried uninstall and reinstall driver several times, but none of them seems to work . ----> That means I can't even use adb to restore the phone simply because my tablet is not recognized in window.
Is there anyway to fix this problem? I really need your helps as soon as possible.
Thank you for reading !
Get to bootloader. Then use Wugs toolkit, open advanced options. On the very left is something like "temp boot to recovery". Once that boots it to recovery, ADB should work. It did for me. I was in some trouble last night and got out by this. If you know how to use adb/fastboot commands, you should be good. And I uninstalled my drivers and when I plugged it in the device automagically reloaded the drivers. But you have to do it a few times. Had to do it in bootloader, recovery, and another point. Anytime it asks to load drivers/etc do it.
I can't boot to recovery through Wug Tool Kit. It keeps saying Fastboot device was not found >"<
By the way, whenever I connnected my device to computer, the bootloader freezes :|
What were you doing before you go into this situation?
I was on Glazed Jelly Bean rom and wanted to go back to stock rom. I used nexus 7 toolkit to do all the work for me. However, there was something wrong like the toolkit didnt extract the stock img right or something like that, my tablet got bootloop, and what happened next was what i had been telling you guys.
Best bet is if somehow you could get into recovery or get adb working. Might want to uninstall drivers and install again and reboot computer. I would suggest using this thread and flash things manually back to stock. http://forum.xda-developers.com/showthread.php?t=1907796 but you would need adb working.
When you power off device and use volume and power can you get it to go into boot loader then plugged into computer try to get to recovery or adb.
Consider deleting the drivers from Windows after uninstalling them otherwise Windows may try to be "clever" and reinstall the bad driver when you plug the device in. The Nexus 7 drivers from Asus can be downloaded here and Google's USB drivers are here

What if I couldn't get adb working?
I tried everything and windows still doesn't recognize my device in fastboot
Have you tried Nexus Root Toolkit v .1.5.4?

try connecting to the usb port at the back of your computer
Paranoid flashed with the bricked kernel did this to me once right after the move to 4.1.2. Even with a full wipe and all the usual safety precautions it just stuck on bootloop forever and wouldn't let me in. I chalked it up as that's what I get for being the guy that's never satisfied with stock. I was unable to get my nexus7 fixed. I sent you a suggestion on pm though.
Never mind everyone. Thank you so much for your help.
I tried install the nexus 7's driver on another computer and it recognized my device in bootloader mode, and restore everything back to stock now. Thank you so much!!!!
Mine did that to the first time I tried. After I got it to work, the permissions were all messed up and I could not get it to download anything off the web and I was getting a playstore error 90% of the time as well. I finally just wiped everything on my tablet, installed the stock rom via N7 toolkit, then reflashed smooth rom, and all is working now. It may have been a bug with the older version of N7 toolkit, as I updated it before I reran everything.
I'm having one heck of a problem here. So I've got my Nexus 7, on stock Android, but rooted and unlocked.
I wanted to try Paranoid Android, so I installed the TeamWin Recovery using the Nexus Root Toolkit, then flashed the ROM and wiped cache/dalvik. I tried to boot into the new ROM, but it just stayed on the boot animation. So I looked up the issue, and the solution seemed to be return to stock Android, then flash Paranoid Android again.
So I tried to use the 'Flash Stock and unroot functionality' of the Nexus Root Toolkit, which proceeded fine until the copying of 'system' onto the device... This lasted for about an hour without progress, so I decided to try again with a different version of stock Android. This too didn't work.
So then I (foolishly) rebooted the tablet. But when I got back to fast boot, it didn't show up in Windows (on either of the two machines I have here, and with two cables that have both worked previously, in multiple USB ports). The specific error is that it shows up as an unknown device (which is fine) but also in the device manager there is error 43, which states that the USB has malfunctioned so it has stopped.
For that reason, it's impossible for me to connect it to a computer or even re(install) the proper drivers for it. And as it doesn't have a working OS, i can't get to ADB either. So right now I can't think of anything that will work - no fast boot, no recovery, no connection to a PC.
Any ideas?
Really, no ideas? Come on XDA Developers, you're my only hope <3
Hi there!
ive got the same issue and i can tell what is NOT working to fix this problem:
deleting ALL usb drivers from pc and installing adb drivers, windows troubleshoot and nrt
i'm just like confused but i think it's all windows fault, if i could i would trie on linux or any other pc os
I had a rooted 4.3 stock image on my N10. Got the notification about the downloaded update for 4.4
It did the update through TWRP (which was weird to me) and finished, restarts and gets stuck on the boot loading screen.
So I went into recovery, and cleared cache, no luck, then complete factory reset, no luck, then I added "System" to that wipe, not knowing what it was an now there is no OS installed.
I installed the Nexus 10 Toolkit (Unified Toolkit) and install the USB drivers, but my computer is not seeing my device..
Help?
As long as you can get to the bootloader, you can reflash a stock image. Easiest way is with wugfresh nexus root toolkit. It will walk you through the driver installation and the various image downloads.
That did not work.
The computer is not seeing my device. Drivers are installed, not seeing it, it's in the proper Boot mode.
I followed the mode that said I didn't need debugging enabled, still nothing.

I would recommend uninstalling the USB drivers you installed with the toolkit and manually installing the Google USB drivers attached to this post. After you have installed the USB drivers I would recommend manually booting into your devices bootloader by simultaneously holding down the power button + volume up button + volume down button. Once you are in bootloader mode I would recommend download this Android 4.4 KitKat Factory Image and flashing it to your device in order to restore things to a working order. Let me know if you still have questions I'll be happy to help you out.
And want explain to me how I copy that file to my device when the computer can't see it?

Check out my previous post and see if those steps will allow your computer to see your device, and let me know how that goes for you.
Ok, I unziped the folder, got the tablet in bootloader mode, which I already said I tried, nothing.
Weird thing, I plugged the tablet into my other computer, it makes the noise for Windows 8.1 that you hear when you plug a USB device in, but there is no notifcation, nothing in device manager, nothing. Just the sound .

I just want to re-state everything to make sure anyone can understand.
This was a Nexus 10 rooted 4.3 Stock. I got the 4.4 update, it finished without issues, but got the boot loop issue.
I cleared cache, factory reset and eventually the system without luck, which left the tablet without an OS (bootloader or recovery only options).
My systems can not detect the tablet, I have installed, re-installed, tried two different toolkits and no luck.
I can't believe it's an actual brick that can't be fixed? Anyone?
Its definitely NOT your tablet. I had similar issues when rooting a Kindle and it was an issue with the PC's USB drivers. If you search the forums for USB / ADB drivers you will find a detailed discussion on how to delete existing drivers (its a process) and update new drivers.

Did you read? I have installed/reinstalled the drivers 3 times.

I also tried a third computer, and another cable. It will charge from a computer, nothing else.
I went through the same experience; it *was* the drivers. If you're using the wugfresh toolkit, it gives at least three options for driver installation. In my case only the drivers from pdanet worked. I've had similar issues in the past with my N7; in that case only the pdanet drivers worked on one computer, and only the Koush drivers worked on a different computer -- both Win 7 by the way; I have no idea why.
I did have to go through the whole procedure described in the toolkit to manually unistall old drivers and manually remove references to the device before reinstalling the driver.
You can get into TWRP, correct? Do you have a USB-OTG cable? You could download a ROM, put it on a flash drive then install it directly from the USB drive. There should be some flashable stock roms, or if you have an old Nandroid backup on your computer (always a good idea to have) you could restore it.

Don't know what a USB-OTG cable is, and not sure how you'd connect a flash drive, but...
I tried one more computer, this time it was a computer with Windows 7 one it. Detected the tablet right away.
So, why the heck does Windows 8 (8.1 to be exact) not allow my tablet to be seen (im sure with the OS on, and booted in, it will)./

This must be why my Windows 8 machines don't work, but I dont remember seeing other driver options, only the one, will keep in mind in the future.
Sounds like the problem is solved, but I highly recommend getting a USB-OTG cable anyways. Go to Amazon and search for "USB-OTG". You can connect flash drives and external hard drives to your tablet. I got mine for $2.

Dear people,
Aparently yesterday I installed the wrong Kernel (Hells Doctor) in my nexus 4, so I couldn´t get wifi. Since then, everything has gone wrong. I installed Nexus Toolkit, but everything was dependant on having the drivers installed at my PC. I tried all driver installation methods suggested in the Toolki: unistalling driver, installing from Google and other places, erasind the USB drivers and installing them again, MTP on/off, debugging on/off, but no sucess. I tried to flash another ROM (SlimRom Mako) on my phone directly, but couldn´t install, it would give error 7 as if it were the image of another mobile phone.
I have tried reflashing, changing the kernel, etc, but now I end in a bootloop were it reboots always into the recovery mode, no matter what I do.
I would greatly appreciate any solution!
Thanks!!
So what exactly is the problem? Cant you connect your device to your pc or cant you flash any rom? Did you already do a full wipe and go with the factory image?
Hi All
I have developed a problem with my Nexus 7 which I have been trying to sort for a bit and don't seem to be getting anywhere. Here is a bit of back ground, sorry it is so long!
I have a Nexus 7 (2012) which while using decided to shut down and will no longer boot up, it got stuck in a boot loop. It is not USB debugged or had any custom recovery on it. I have however managed to get the bootloader unlocked.
I tried to restore it manually following the guide on here but I could not get it to recognise the device despite following every step carefully. The computer (running on Windows 7) sees the Nexus now as it didn't when it first crashed. I have downloaded WugFresh 1.9.9 and tried to restore it from there and it looks like it is working but it now gets stuck on writing system. It does everything to this point fine. I have tried different USB ports, cables and someone else tried it on a different computer (running Windows XP) and he got stuck at the same point.
Can anyone suggest anything else I can do to try and restore my Nexus as I'm at a bit of a loss as to what to do next.
Thanks in advance
Vaughan
