PC no longer recognizes Nexus 4: USB driver failure

Problem: USB driver failure for Nexus 4. The android composite USB driver loads. Portable device driver (MTP) does not.
I have the latest v7 Google USB drivers in the extras 4.2.2 SDK folder, and pointing the driver install to this folder has worked in the past. Now, I never get the portable device MTP to install. I have both windows 7 and windows 8 machines that used to recognize the phone. I suspect my phone USB firmware is corrupted ( or something else software related?), but don't know how to find or make a zip file I can flash via custom recovery to test my theory.
I've tried multiple USB cables, all which have worked in the past. Simultaneously, I can only charge at USB rate. This all started occurring a week ago.
Any recommendations?
LG-E960

A different Nexus 4 connects fine, mine has no response to USB. It will charge off the PC, but no adb device found, no fastboot device found, no portable device MTP. I think something is wrong with my USB firmware on the phone.

Are you sure usb fast charge is not on?

User failure in this case, install these drivers from here http://forum.xda-developers.com/showthread.php?t=1998650. Delete all excisting usb drivers and then reconnect to usb and prevent/stop windows from installing drivers. Open device manager in windows and select the N4 and install the 0.72 drivers and you`re done.

I'm having the same problem, ADB, MTP none of it works, I've tried every method including yours. Worst part of it is that nothing happens in the device manager when i plug in Nexus 4 so i can't update drivers manually too. It used to work great with both MTP, ADB etc. Stopped working all of a sudden...Help please anyone. The phone is pretty much useless without MTP or ADB for me.

I too,, have tried to clear all old drivers and use the universal driver, but nothing works. I went through the tedious windows 8 advanced startup to allow unsigned drivers.

This sucks. I still cant resolve this, and 4.3 is coming. Maybe I'll try Ubuntu.

Problem with Nexus 4
Any updates about this?
I'm going through the same thing with my Nexus 4.
No response to USB, except charging.
No ADB, No Fastboot, No MTP nothing at all, it's as if the system detects only a device that uses power from the USB port and nothing else.

It was the same with my phone. Wasn't detected on other computers too.
Here's what led to the problem resolution (kinda):
1. Formatted /system, /data, /cache, and flashed CM 10.1.2: http://get.cm/get/jenkins/34261/cm-10.1.2-mako.zip
2. Restarted the phone, then I came upon this forum post which mentioned that Trickster MOD Kernel Settings should be used to test for fast charge.
3. To install Trickster Mod I had to have Play Store (and thus the GApps package), so I rebooted into recovery.
4. After flashing the GApps package and rebooting the phone got detected and I was back in business.
5. Immediately flashed the factory image JDQ39 (it was the one I had available at the time.
6. Received the 4.3 OTA update about an hour ago and the phone is again back to not functioning on USB.
(Worth mentioning here that before this fiasco started, I was on CM 10.1.2, linked above.)
-- Update --
Rebooted a few times, phone appears on USB now and is there consistently, I'm beginning to think this is a hardware issue but I cannot apply for a warranty claim until the problem is consistent enough.

I've been having the same problem the last few weeks. I am on v4.3 stock. The phone is not being detected in any computer i've tried. I've used several USB cords and none of them work. The phone can be charged, but only in USB mode, so charging is slow, even when using AC charger.
I think this problem was triggered by charging on a cheap car charger. The Nexus 7 also can get into this state from what i've been reading.
I haven't come across a fix yet, so I think I'm going to RMA it before the warranty runs out.. its to bad though, I think this is a software problem related to 4.3. I used a lot of cheap chargers without this problem coming up before upgrading to 4.3.

Just go to storage settings and just try uncheck and re check the option of USB connection . It worked !! for me

Tried that. I also replaced the USB flexible circuit card ($25 amazon) and nothing changed. I'm glad their are people like xDA member, enfrant, that provides zip files for updating the phone, else I'd be stuck with a non- updateable nexus 4, which would be a nightmare for a flash junkie.

Very basic step but I've seen it being missed before:
- Go to Settings
- Storage
- Menu > USB computer Connection
- Check Media Device(MTP)
If this was not checked, checking it will make your computer download the necessary drivers if not present already.

Need help recovering my n7

When I turn my n7 on all I get is the android with the red triangle over it and underneath it says no command. I'm unable to do anything with it. When I press power & volume up all it does is dim the screen/undim it.
From what I've been reading, I think I need to load a recovery image, but when I try to load it, I'll either get a DLL error, or in command prompt it'll give me an error saying the image can't be loaded.
The DLL error is something like adbwin.dll & its frustrating because its in the sdk\tools folder, I can see it & I've tried setting environmental variables in control panel/system to the DLL path & I still can't get my system to see it. Any help would be appreciated.
I'm using windows 8 and the recovery image I tried was twrp 2.2.1. I'm missing a step somewhere I'm thinking.

No suggestions? Uggghhhh
Is there anyway to install drivers without enabling USB debugging?

Look up Wugfresh's Nexus Root Tool Kit.
Once you install all of the drivers it'll be a breeze....

Tried this already too just last night. I've tried using samsungs mobile phone drivers, asus', and the naked drivers. I can't get this thing to be recognized. its not even charging when plugged in to my PC. I've also tried it on a w8 PC & win 7 PC.

That's an entirely different issue then. Try a different cable?

Have you tried to do something simple at the error screen with fastboot? For instance just do a fastboot devices? Does it return anything? Have you properly configured your PC to run adb and fastboot? Are you trying to run fastboot/adb from the directory all the files are stored in? I know this may be basic stuff to some, not sure of your level of skill, but even still professionals still can overlook something.

Here is the latest Android Composite ADB Interface Driver straight from SDK.

If you can get into bootloader then you can erase your existing partitons then flash all the images from the Nexus Factory Images package to restore your device to stock.

I tried running cmd to check for fast boot devices but nothing came up. Tried root kit to detect & nothing is detected either. All my files are located in C:\ which is where I had fast boot pointed to.
I'd say I'm pretty noob at this. It was originally rooted & no orobs till this instant. I'm pretty positive adb/fast boot is installed correctly.

USB debugging is not needed to use Fastboot.

Have you tried power and down? That's how you get into recovery. I just reread the first post and you stated that you're pushing power and up volume.

I'm thinking along the lines of a hardware issue with the usb port...

[Q] USB and recovery problems after OTA upgrade to 4.3

I took the OTA to 4.3 on my Nexus 7. It was previously unlocked and rooted, but had no kernels, etc changed. After the update ran, I lost root as expected, however, in trying to get it back, I've discovered I'm having a couple of other issues.
First, the device is no longer working properly via USB on my PCs. On both my Win 7 and Win 8 PCs, the device won't properly connect to where I can browse files or anything else. On the Win 8 computer, I see a Nexus 7 device in Device manager, but drivers won't install. I downloaded the drivers from the Asus site, but trying to manually install them doesn't work on the Win 7 machine, and on the Win 8 machine, they install but don't seem to be working with the Nexus 7 as it still shows a problem in Device Manager.
The tablet also will not boot into recovery mode. I can power it up into fastboot mode, but if I select "Recovery Mode" and hit the power button, I just got the Android with the red triangle for a few minutes before it boots back into the OS. After doing some searching, I saw where you might need to have it plugged into a PC to get it to go into recovery, but that doesn't work, either (might be tied to the USB problem).
Ideas?

Did you turn on developer options, and USB debugging? Have you tried USB connection type PTP instead of MTP?
If you have the stock recovery, the red triangle and Android are normal. You can bring up a blue options menu by pressing the power and volume up buttons from the red triangle Android.

Try another driver source. Wugfresh's installation is a lot tougher than Skipsoft's, but try the other guy 's system.

I was using the stock drivers off the Asus page. I'll look around for the two you mention. I assume they're posted on here somewhere.

Without USB access? That's my dilemma.

OK, I'm getting closer. I got TWRP installed and rerooted it. I had to do the "Revoke USB debugging authorizations" on the Dev Options screen. Then it would work via ADB.
Still not browsing files yet on my desktop, but at least I know I'm talking to it. So now I'll play with the driver installation a bit.
EDIT: Well, drivers reinstalled for about the 4th time, and it's still not allowing me to browse files from my desktop. Galaxy S4 works fine as soon as I plug it in, even if I also uninstall it's drivers. Ideas? I obviously have it working over USB because I can give it commands and reboot it via the PC.

OK, try this one. Plug in your tablet to pc, go to hardware manager, find your Android Device then choose Uninstall (choose Remove all drivers for this device), unplug and plug in your tablet again. Your Windows should discover few new devices (mine has discovered three) and download drivers for them then you should see Android ADB Interface in Android Devices and Nexus 7 in Mobile Devices.

After you plug your nexus in have you unlocked the screen to see if it is asking you to authorize the tablet?
What other steps have you taken? Have you installed proper drivers? Have you manually chosen to update drivers with the sdk drivers if in device manager is showing the nexus? Have you tried the drivers from Asus?

I personally did all of those things. After having the Nexus "forget" all the other PC authorizations on the dev screen, I finally got it to accept ADB commands, just not to properly install drivers that would allow me to browse files like it had done on 4.2.

[Q] adb working correctly fastboot wont recognize device

I encrypted my phone without realizing that CWM did not support encrypted devices. To fix this I was going to install TWRP since it does support it. My phone is working correctly with adb but I cannot get fastboot to find the device at all. This is making it so I cannot install TWRP on my phone now. Anyone have any ideas or suggestions? Thanks for any help.

You can install the recovery directly through the phone through Goomanager, but the fact that your computer doesn't recognize the device in fastboot is an issue I feel needs to be addressed. Goomanager solves the problem of the recovery, but I'm not sure about the fastboot issue.

I had this issue on a different device. To solve it I went into control panel, device manager. Then look for the usb device that had an exclamation mark on it (with your device plugged into the usb port). Right click on it and update driver software. Then go to browse my computer and choose, let me pick from a list...... Pick the android composite adb interface. It'll ask you if your sure, just say yes

Thank you, thank you, thank you. This enabled MTP mode for me in about 3 seconds on my Windows 8 PC. I had tried using Wug's toolkit both automated and manual even disabling enforcement of digital signatures on driver installation and had also installed latest ADK and Google drivers to no avail (all that got me was connection in camera mode and ability to see only DCIM). I don't remember having this kind of trouble last time I decided to play with my Nexus 4. Not sure if I was using my old Windows 7 machine then or if there is a conflict with the other drivers on my machine (I have recently flashed both Motorola and Samsung devices too). I wish you had posted a couple of hours sooner lol.

Nexus 4 - bricked? - TWRP - no OS installed

Hi All,
I bought a Nexus 4 on eBay thinking I could fix it but I am really struggling.
The nexus 4 has TWRP 2.8.6.0 but that is all.
I cannot enable USB debugging as I don't have any rom installed.
I have tried a USB OTG cable with power, but have learned that the phone still cannot output the right power? The light on my usb stick comes on but TWRP does not list any USB OTG.
This phone does not have an SD card slot, so I cannot load anthing this way.
Is it impossible to get this phone working?
Kind Regards,

Have a look at this thread ..
http://forum.xda-developers.com/nexus-4/general/how-to-how-to-flash-factory-image-t2010312
(Read the thread thoroughly, and take notes, its real easy to get lost in the middle of the procedure and mess it up, and having to start again).
Flashing the stock rom is done entirely via fastboot, so you shouldnt need to worry about adb.
If you can boot into bootloader you should be able to flash stock image, once you get the windows drivers sorted. Luckily I'm on a Mac, so drivers haven't been an issue. I had a similar scenario sometime ago, and after flashing stock, all was good in the world again. I may be wrong, but you'll probably need the latest platform-tools (which contains fastboot) if you're flashing the latest stock images. (Someone correct me if I'm wrong on that one).

For information I am using a cable from a usb cable that came from a Nexus 5.
When the phone is connected to the PC it had an android lying down with an open chest.
When pointing to the android developer sdk drivers as above it does it's usual thing of saying it is already up to date below that still saying unknown device. I'm so frustrated right now.

Sounds like youre in the right mode. The problem would likely be on the pc/driver side.

The driver issue is a massive stumbling block.
I'm still not sure if the cable will work.
I understand I can use fastboot after the PC recognises the nexus 4.
I have a Lubuntu PC this may help me but I have no idea where to start in terms of the drivers.

I use a mac, so im no use when it comes to linux variants etc.
Depending on the power of your pc, you could try using a virtual machine (i.e. virtualbox running windows xp if you have xp disk, or even windows 7). Ive done this before on the mac (xp virtual machine) and it works. This way you can install the correct drivers on a fresh install of windows, without messing with the host OS.
Otherwise, best bet is to uninstall any drivers in your current windows, and install divers from google link i posted earlier.

just outta curiosity, when you plug the phone in (in bootloader mode) change dir to the one with fastboot.exe in and type (in command prompt):
fastboot devices
what output do you get?

Just to check I am doing it correctly, I launch cmd in windows, change the directory to the location where fastboot is and type "fastboot devices". The result of this is it just gives the directory name again waiting for another command.
I hope I'm not coming across as ungrateful, I assure you this is not the case.
