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.

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.
... and is no longer recognized when connected to a computer via USB, meaning I can't return to stock to get ready for the Lollipop OTA.
Got a rooted Nexus 4 running the latest PA beta.
What happens when connecting to PC:
- On two different Windows machines: systray popup saying "USB device not recognized. The last USB device you connected to this computer malfunctioned etc.". In device manager it says "Unknown USB device (device descriptor request failed)"
- On elementary OS, based on Ubuntu 12.04: nothing, besides charging.
No USB debugging connection notification on the Nexus 4 either when plugging in.
What I've tried (USB debugging enabled, all relevant drivers installed):
- Settings > Storage > USB computer connection > check Camera PTP (used to be required in order to get an RSA key prompt when connecting to a computer, now it does nothing)
- Flashing latest stable CM to see if PA was to blame. Made no difference.
- Uninstalling device through device manager in Windows and reconnecting. No effect. Driver update doesn't work either, finds nothing.
- Using Wugfresh's Nexus toolkit to see if that worked, but that obviously doesn't work either when the device isn't recognized, same with the Universal Nexus Linux Toolkit on Linux.
- Scouring the net for solutions and coming up with nothing
I have flashed factory images before on this phone without problems. Should I consider it a hardware failure by now, or is this a known issue with a fix?
Try a new wire, different usb port on computer, finally look into cleaning your charging port on the phone/replacing it.

Tried three different cables, every port on two laptops, no joy - my girlfriend's phone connects normally.
Wouldn't replace the charging port, then I'd just get a new phone since it's a 2 years old Nexus 4. If only there was a way to flash the factory image using only TWRP.

Flash this in twrp http://forum.xda-developers.com/showthread.php?p=47476426
Sent from my Nexus 5 using XDA Free mobile app
Thanks jd1639, that seemed to be exactly what I was looking for -
- but then I had an extremely blonde moment and formatted everything in TWRP, wiping the ROM I was gonna flash in the process, on a device where USB file transfer doesn't work anymore
My phone is now a paper weight.
Have you tried the file manager in twrp yet? I've found it connects when nothing else will...
Trying to breathe life in this old tablet. Using current Andrdoid SDK USB driver. ADB works fine. Boot into bootloader and fastboot devices sees nothing. Been banging my head on this for hours, trying to manually modify android_winsub (which I've done in the past with various devices..but not on win 10). I've disabled device driver signing. I've added entries in the two locations, pulling the PID/VID from Device Manager.
..was going to cut and paste the changes but my desperate SDK install killed my backup copy.
basically it had no %SingleBootLoaderInterface% = USB_Install, USB\VID_18D1&PID_4E40
for the Nexus 7 (no longer remember why). Tried pulling the values from Device Manager but no go, I should have screen shotted the error.
So without fastboot I tried using Flashfire. It failed, leaving me with no Recovery, Boot Failed when I try to enter recovery. so the TWRP app isn't working either (not sure why I didn't use that to begin with). I had 3.0.0.0 on it.
I have been googling for hours, not an uncommon problem, but no solutions have worked for me.
Help?
Here's what I see in device manager when in fastboot mode:
ok scratch that, in USB controller section there was an errored item which is gone now -- but fastboot still not working. Fastboot devices returns nothing. I;ve tried multiple cables, USB3 and USB2 ports, I really don't like not having a recovery nor means to install one......Interesting that device manager no longer shows an error though after yet another Google USB driver install. Making it even harder to troubleshoot.
If I could be given the exact dd parameters to run, I could conceivably dd TWRP 3.0.2.0 into the correct location I just realized...at risk of bricking. I'm willing to take that risk if anyone knows with 90%+ certainty the command.
I found some useful info on ways to do it, but adb remount command no longer exists so don't want to continue on those instructcions..
definitely seems like a driver issue, have you tried drivers available in wugfresh's tool?
Yes. It can't get any response from bootloader either.
I'll make a restore point and try again....
Edit: If I could find a flash_image binary that works on N7 2020 wifi (grouper) I could do this.....

And wugfresh's #1 driver recommendation.... Is Google's drivers. But I tried #2 universal drivers, no change. I noticed my Android SDK winusb.inf didn't even have a bootloader section on nexus 7. No idea why. I am on latest version. Deleting and reinstalling did bring back an entry, but not the functionality.

Bump for ideas? Windows 10 not seeing bootloader's seems a common problem, but most remedied by drivers
Sent from my Nexus 5X using Tapatalk
I have won 10 x64 and it works just fine. Install 1,2,3 adb fastboot deivers, but boot windows in mode that allows unsigned drivers.
Use original usb cable. My N7 had usb port problem, it wasn't detected as normal device
I've followed some instructions that instructed disabling driver signing, didn't help, but you may be on it with the cable. Original is long gone but we know how hit or miss cables are, and I'm using a connector/cable extender. Great idea to try a few quality cables. The current rev Google drivers DO have an entry for bootloader mode in N7 (not sure why mine were missing and I was trying to manually add them). But even then the unknown USB device in device manager reports different PID/VID than is in the inf file. Edit: But that extender could have been muddling things. Anyway, great suggestions to work on. Appreciate it.

try to cut some plastic at 45 degrees angle, so it goes all the way to the port. My S7 cable did't work well, so I went with SWR50 sony cable, cut it a lil bit and it works like the original from N7
Not sure what I would do with the plastic? Insert as a wedge into the port? My trick to getting old cables working in old connecters is use my eye tooth and bite gently down on the metal on the long side. Creates a little v crimp that brings the cable back to life. Trick is how gently you do it.

I have a 6P running on android 8.1 SuperXE rom. And when i tried to run Substratum and it asked me to download the Andromeda app to make it work so I did. Then i went on my Desktop downloaded the script for that followed all the instructions. Now after running the script a couple times my phone no longer works with adb. It is not a computer problem because I have tried to plug it in on multiple computers that have the right drivers installed and none of them work. It seems to be a problem with my phone.
I have tried factory resetting my phone uninstalling and reinstalling drivers. Nothing seems to work.
Has anyone ever run into a similar situation?
Also the error that shows up is USB device not recognized, "the last USB device you connected to this computer malfunctioned and Windows does not recognize it." It says this on both my windows computers, and my Linux laptop. So I know it has nothing to do with the phone cord or the computer.

It's probably the chord try another one. And if you root your phone with magisk you won't need Andromeda and Android pay still works. I'm on SuperXe also and don't have any issues. It's pure stock with some add-ons and customization.
Check with another cable or clean flash a stock rom via fastboot to see if the issue still persists, mm,n or o, it doesn't matter.
Edit: first go to Dev options and reenable USB debbuging and set USB configuration to mtp, may a phone reboot is required.
Edit: to reset the USB debugging authorization is worth a try too.

The first time I installed 8.1 it said it required Andromeda to run, but after I wiped my phone and re installed 8.1 it worked without it. Which was weird.

I went out and got a new cord and now it is working thanks for the advice. It's weird though because nothing was wrong with the cord before this incident.
But thanks for the advice it was the cord I have a new one and no problems thus far.
Not to hijack this thread but I am having a similar issue. My nexus 6p and an old Nexus 6 will not connect to any computer. I have used different cables and still no dice. I have a Nexus 9 that connects fine. Both Nexus 6 and 6p charge on the cables but will not connect to computer. Any thoughts or suggestions. Again have tried different usb ports in same computer 3 different computers and multiple cables.

May start from scratch with the drivers, download usbdeview (simple Google search) and get rid of all nexus and or android installed drivers. Reset USB debugging and authorization on the phones, set to mtp, do a reboot and do a fresh connect.

Neither my Nexus 6p nor the 6 show up in usbdeview. Only the Nexus 9. Tried revoking. Have done factory reset set to mtp turned debugging off then on restarted phone different cables still doesn't show up in usbdeview.
Also the point of all this was to try to get this to work with my Mavic Pro drone. Which also does not recognize my 6p and thinking about this now my car also does not auto launch Android auto like it used to and in fact does not work at all. Phone charges from usb but does not seem to communicate.
Faulty phone maybe?
Is there a way to get off Oreo without having usb access? Not currently rooted and the apk's I have tried seem not to work.

It's strange that your n6 and n6p both don't communicate.
If you got TWRP installed you can root and flash what ever you want with flashfire. Or with TWRP itself. But never ever flash bootloader and radio with flashfire, it isn't necessary all the time anyway.
Or is your n6p completely stock ???
Uhh, I do miss my Nexus 6
