[Q] Device Manager Error 43 + No ROM installed

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

KitKat on Nexus 7 Failes

My problem is basically getting my nexus 7 to connect to the pc... This is what I've done. and what happends...
When I first connected it, I got no message at all, and nothing happened, then I changed the cables around, I changed the USB Pports... and by some mysterious wounder I found a combo of pad, port and cable that made my nexus go your connected as MEdia Device... BUT my computer wont see it.. hmm.. changed it to camera mode, and still nothing. Then I turned off USB Debug. Still nothing, but wen I turned it back on, I got the message that I was connected, and I got to install some drivers, and NExus popped up as a camera in windows 8... Started up the nexus toolkit thingy (I love simplicity) And there it popped up.. rebooted to fastboot, and no luck... windows wont recognize the damn driver. And I have done everything I can think of except install linux and try it there... IT wont connect in Fastboot mode, Not a chance... I've tried to unindatll all the drivers, and their files. everything I can think of... I've followed like 20 diffrendt howto s on the same problem, and no luck...
So how would a guy like me go about doing this in linux... is there a tool made for it? Do I need to do it all by commands? Is there a howto?

In my win8 64bit the nexus 7(2012) does show up as a portable device, but MTP works and there's no issue with sending or pulling files. currently it's running stock kitkat 4.4 (KRT16S).
like you I suspect it's a driver issue with windows. If you could locate the device on device manager (try View\Devices by connection and look under PCI Express Root Complex and comb for USB Host Controller\USB Root Hub\Generic USB Hub), delete the entry for Nexus7 and scan for hardware changes again. This forces the system to look for correct driver(s) for your nexus.
Some guides on updating drivers are in fact concerned with the ADB interface, which is needed for USB debugging. In your case, if it's just accessing the internal storage of your Nexus you want to solve, those info may not be relevant.

Basically I would like to have ¤.¤ installed on my Tablet. Right now I have 4.2.2 SmoothROM installed, and whilst this works for me, I'd like to get the update.
In the past, I used the Toolkit to root and install stuffies... Until the last update to SmoothROM wheres I used GooManager thingy...
When I started this I got the Tablets to connect using PTP whilest in Android, but not in Fastboot mode. So I downloaded the 4.4.kitkat Offisial ROM and tried to install that in recovery, after a full wipe, BUT that ended in me having to install SmoothROM again. And now the Tablet wont connect at all... I have deleted all drives, and reinstalled them... I've tried 3 diffrent Wondows USB driver, but no luck there... I've tried like 5 diffrent USB data cables, in all 4 of my USB ports, on 2 diffrent machines, both win 7 and win 8... AND still no luck... now all the machine says that it cannot identfy the device...
Tomorrow, I will end up installing linux, and try there... At the moment I loathe all things called windows drivers...!!!!
EDIT:
Great news... I found a cable, I havent used in a long time. THis is the original cable that came with the Nexus, and I havent used it in a long time because it had some bad connections. Felt like the plug was loose, but now it made the whole thing work without any problems at all...
So I found the cable, used USBDeView to delete all drivers assossiated with the nexus. plugged it in while in fastboot, and BANG installed. rebooted it, and BANG installed.

Bricked & Unseen...

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 ^^!

ADB doesn't work

When I plug in my phone to my PC the only thing that happens is it begins charging. Doesn't show signs of adb working, only thing that happens beside charging is my pc says it's an Unknown Device.
I tried all sorts of things, like USB Debugging on and off, MTP on and off, PTP on and off, I think even fastboot doesn't work. I tried to install all kinds of drivers (official, unofficial, uninstalling them afterwards if they didn't work ofc), I tried Wug's toolkit, nothing. I tried killing adb server then restarting it - nope. I even tried all of my USB ports, both 2.0 and 3.0. Also tried 3 different roms/kernels (L dev preview, Purity and Mahdi), didn't work aswell.
Things seem pretty hopeless at this point :/

Download wugfresh toolkit... look In the section of driver installation... They'll help you out
Sent from my Nexus 4 using XDA Free mobile app

driver installation...

As I said, I already tried the driver thing in Wug's Toolkit. Also my Windows allows unsigned drivers.

Bump :/

If it still says Unknown Device on your PC, its a driver issue. Personally I use the Google usb driver, that page also has instructions on how to install the driver. Try uninstalling whatever drivers you have installed right now, then install Google usb driver carefully following instructions. Fastboot needs bootloader mode, so make sure your phone is in that mode before trying a fastboot command. I use the Minimal adb installer to install adb/ fastboot tools.

Fastboot actually works, only ADB doesn't. I use the Android SDK to install adb/fastboot and I tried Google USB drivers and also Universal ADB. I tried the drivers from Wug's Nexus Toolkit and then LG drivers, same old story :/
Edit: I upgraded from Windows 8 to Windows 8.1 using clean install, still same problem.

Might be windows 8/8.1 giving you driver signature grief. Try the Universal adb drivers:

Huge mistake

Hey guys ,let's get straight. I'm totally dumb.
After flashing Lollipop factory img which reseted my internal storage (made a backup on PC), today I decided to try AOSP. Downloaded with my phone, flashed it. But the file was corrupted (bad download or something). Results : I only had that rom on my internal storage, my phone won't boot. I thought I could use NRT, although it as always worked fine, now it keeps telling me "adb device not found", "no fastboot devices". So, actually I can't do anything and I can't see what can I do.. already tried reinstalling drivers, but windows isn't even showing my nexus 4 on device manager
Looks like I need help, and sleep too..

Hmm can you get at least to the bootloader menu. If you can, there's still hope. At this time, you're better off using the manual commands rather than the NRT (the NRT use a set of pre-configured scripts and doesn't always end up where you would like to) Have you tried to also plug your device inside another USB port?

Yes I can acces to bootloader and TRWP. Tried another USB port, another USB cable, using manual commands it says " <waiting for device>" and nothing happen..

What drivers are you using. I use the Google usb driver available here

How to install these drivers here

You also need the android platform tools installed on your pc for adb and fast boot commands to work. I use this installer

Make sure you have completed these steps on your PC before you connect it to your nexus.

Thanks buddy , but my drivers were fine before all this. And now i can't reinstall it that way since my nexus isn't even showing up on device manager, I used another method from NRT. Gonna test on w7..
EDIT: Problem solved using windows 7. There seems to have problem with drivers on windows 8.1

Yes, in windows 8 you need to disable driver signature enforcement. In windows 7 no problem.
