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

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.
Hi guys,
I want to go back to stock since 4.4 is coming. However, when I try to flash the stock rom+ with Nexus Root Toolkit 1.7.3, I get stuck at the whole fastboot part. Fastboot IS working on my Nexus, but the drivers cause a lot of trouble. Installing the drivers when my device is running normally ( so no fastboot mode or whatsoever) works fine.
I have followed the Full driver installation guide where I tried options 1 till 4 but they all get stuck at the point where my device reboots into fastboot mode. At this point, my computer doesn't recognize my device and gives me an error. My nexus is shown in the device manager as unknown device and updating the drivers manually by redirecting my computer to the NRT drivers does not work. It says it cannot find drivers for the device. Does anyone know what I might have done wrong?
Or is it possible to flash a stock rom through twrp? like this one? http://forum.xda-developers.com/showthread.php?t=2376881
TL;DR: use a machine with Windows 7 installed. Or boot ubuntu from a usb stick.
I've researched a lot about this, I had to downgrade my dad's phone with Flashtool (for Xperias), and after trying about every tutorial I encountered (removing drivers, installing different drivers, changing ports, disabling driver signature verification in Windows, I installed android studio, adb separately, running everything in administrator mode), I remembered I have a W7 machine on the other desk, it worked like a charm.
W8 (or 8.1, it's the same thing) is bad for flashing, I don't know when they're going to fix it.

Yeah, I tried the same things you did, including disabling driver signature verification but it won't work. I'll try a windows 7 machine.
Thanks for your answer!
Ok, here goes my story.
Just a week ago from the date this was posted, I decided to update my recovery (TWRP) through ROM Installer. Surprisingly, I didn't see TWRP at all in the "Recoveries" section of the application. Stock, ClockworkMod Touch, regular Clockworkmod (no touch), and unofficial Clockworkmod were available - from what I can remember. I decided to use Clockworkmod (no touch) to install Paranoid Android. Coming from OmniROM, I factory reset and flashed the .zip.
Flashing ended in error with Status 7. A while before I had used ClockworkMod Touch to try another ROM and had no such issue. I ignored the error and restarted my tablet hoping that it would still boot fine. It rebooted, gave me the Google logo for about 5-10 seconds and automatically rebooted into recovery.
I saw a bypass for Status 7. Removing some lines from the updater-script was the solution. Having no access to my Nexus 7 storage, this bypass is unusable
I tried flashing a new recovery using flashboot fastboot. After verifying that I had my drivers installed (Universal ADB by Koush), I opened up adb in the command line (Windows) as an administrator. I could not see my device. I tried the drivers from Asus, multiple USB 2.0 ports, and a different USB cord, but same results. I tried on a different computer. Still no detection.
Systems used: Windows 8.1, Windows 7 (x64), Windows 7 (x86)
I tried using Wug's Toolkit and used Flash Stock + Unroot, since it didn't need USB Debugging enabled. Same results...
I also tried plugging in another Android phone (LG Optimus Dynamic II) to see if Windows would recognize it. Windows recognized it, installed drivers automatically, and was recognized in ADB immediately. This practically unknown phone (XDA doesn't have a section for it yet) could be recognized, but my world famous Nexus 7 2012 can't be seen.
I have absolutely no idea of what to do now...
Are you on the bootloader screen when trying to use fastboot?

Yes. Every time I use fastboot, I am in the bootloader.
I'm not new to this at all, so say whatever you need to ^^
The main problem is my PC not recognizing my Nexus 7 through adb. Again, I have used multiple cables with no success.
The computer I am using for this runs Windows 7 x64. I have only tried using USB 2.0 ports to connect my tablet.
Thank you!
Might try deleting the drivers and starting over. I had some issues with adb drivers for both the N7 and the kindle fire on windows 7 as well, but eventually got both working by doing this several times.
I'm assuming you ticked the option for softbricked when trying the flash stock option? If not try again and check that option.
This thread http://forum.xda-developers.com/showthread.php?t=1907796 has a section on driver installation with good info and links too.
Hope that helps. Best of luck man, getting the adb drivers working properly seems to be finicky sometimes in my experience, and i'm no stranger to PC and software troubleshooting either.

Thank you so much for all of this! I'll need all the luck I can get...
By the way, I checked that softbrick option ^^!
I know what your thinking another newb not installing drivers properly or hasn't changed to file transfer mode.... This is not the case. I been installing adb and USB drivers since the og droid.
I have a real problem here....
I been on custom ROMs and wanted to fastboot back to stock however none of my computers are detecting my phone... Tried on 2 windows 10 x64 and one windows 7 x64 with same result. None even pop up a notification or ding a sound that the phone has been plugged into it. Nothing in device manager either. The phone charges at least I have also tried 4 different cables granted 3 came in a bundle pack that I do not trust but reviews state although not full speed they should do data....
Now here is the kicker:
If I turn off my phone and boot to the bootloader my 3 computers detect a device has been connected but the drivers fail and say something about the device signature can't be recognized. I have tried disabling the device signature validation in windows 10 with no luck and also windows 7....
Tried manually installing the drivers but says not compatible with device hardware
At this point I'm baffled luckily I'm rooted twrp and can download files to install directly but I rely heavily on fastboot as my goto if something goes wrong I'll be hosed!
I did factory reset and even flashed another custom rom to see if it was the ROM I was using.
Please help if you have any ideas to try. I have yet another cord coming Friday just in case the offchanse the main went bad and the other three from the bundle pack are ****
Sending back to google I hope they don't mind the custom rom, unlocked bootloader and twrp recovery lol
Hi all,
My nexus 6p is not recognized by any PC since I flashed Resurrection Remix 6.1.0 [8.1.0_r33 Oreo] 5 months ago. I have been busy and never bothered about that. Recently I tried to flash StatixOS 9.0 and got stuck at the boot logo. I thought of going back to stock rom by using fastboot and wiped the memory. Now fastboot and ADB doesn´t recognize my phone and I am stuck with no OS and no option to flash one.
Previously I used my laptop several times to fastboot flash roms to my phone and it worked flawlessly, I have installed drivers again, used different PCs, swapped cables, USB OTG, tried Wugfresh, SDK manager drivers/manual drivers installation but none worked. PC doesn't even recognizes in other devices or anywhere in device manager.
Any possible solution? It does charge without any issues. Since flashing RR 6-1-0 it never even showed which type of connection I want (charging only/ MTP/ etc).... is this a software issue ?? what am I missing something here? or the daughter board needs to be replaced??
I have been through every possible threads in and outta XDA but no luck trying those tricks.....
TIA
