Nexus 4 Rooting Help

I need some help on a specific problem for rooting the N4.
I'm trying to use the Nexus 4 Root Kit to root my N4 and for some reason the Nexus 4 Root Kit is not recognizing my device when it's plugged in. I went to device manager and I saw that my N4 is under:
- Portable Devices
- Nexus 4
In all the video examples it's put under as an Android device instead of a Nexus 4. Is that what the problem is? Anyways I'm just trying to install the PdaNet driver for my N4 using the root kit and I keep getting:
Android Phone not Detected (Error = 103).
Help please?

Have you enabled developer mode (tap "build number" 7 times under phone info)?
Then within developer options, enable USB debugging.

I have enabled USB debugging.
For whatever reason, my computer continues to install the "portable device - nexus 4" driver instead of Android ADB :/

Have you tried the steps listed here?
http://forum.xda-developers.com/showthread.php?t=1992345

I downloaded those drivers and it worked as in my device manager now shows android device --> android composite ADB interface.
However on the Nexus Root Toolkit, when I press unlock and it's checking the ADB status I get:
"ADB device was not found"
Any further help please?

Try restarting your computer.

Other solutions that come up are:
- Make sure you're using the cable that came with your phone
- Make sure your firewall or anti-virus isn't blocking ADB

Unfortunately that didn't work haha. Well, thanks for the help! I've decided to just give up on rooting since this is not nearly worth the trouble I'm going through lol.

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 a hardware problem at my end. My nexus 4 wasn't detected at all in any computers.

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.

Nexus 7 not showing up

My laptop won't recognize my nexus 7. It's running Windows 7. I looked up possible solutions on Google and none really worked. Help?

Which ones did you try?

I tried using a different cord, plugging the cord into different USB ports, rebooting the device as well as reinstalling the drivers.

Then you haven't tried everything yet
A different computer? (will verify if it's the computer)
Uninstalling all USB drivers then reinstalling them?
Watching what happens in Device Manager when you plug in?
Switching debugging mode on or off on N7?

One of those options, I held off on since I was confused on how to exactly do it.
I can't really use a different computer because I'm trying to move around 15 GB of music located on the laptop I'm trying to get to recognize the Nexus 7 ..and the other computer is damaged lol.
The second option is what I was confused on. How would I go about doing this?
I'll try the third and fourth now.

I switched to USB debugging and it installed some drivers again. "Google Nexus 7 ADB Interface Installed" It said this when before I turned on USB Debugging. Still doesn't show up as a drive if it's supposed to.

You need the other computer long enough to verify if the N7 is Ok.
You're not going to be transferring stuff.
Just a diagnostic step. Any computer running XP-8 will do.
I'd do that before playing with the drivers. You've got to have access to another computer somewhere for 3-4 minutes.

It should show up as an MTP device.... http://android-ios-video-tips.com/how-to-transfer-files-to-your-google-nexus-10-nexus-7-from-pc/

I tried uninstalling drivers through device manager before and installing them by connecting the tablet back into the computer and still nothing.
Should the Nexus 7 ADB thing be showing up under SAMSUNG Android Phone? (edit)
*Edit again*
I got it to work by checking "Delete Driver Software" when uninstalling the drivers from Device Manager. It's not showing up under SAMSUNG Android Phone anymore but I think that's because I havent connected my s4 yet. Thanks for the help!

Not unusual.

I was just going to add that sometimes 'delete' is preferable to uninstalling.

I had a similar problem.
My Nexus 2013 LTE model was connecting perfectly but using the same port the 16 GB version was not able to show up.
Checked the device manager and it did appear under Samsung Android device. Deleted the drivers and got them to install again after connecting.
Now the Nexus 7 appears under portable device and works perfectly.
Thanks for the idea

USB driver trouble

Ive been searching and trying for quite some time now for a solution but I have yet to find one.
My problem is this, I've soft bricked my Nexus 7. I can get into fastboot and recovery (CWM).
My computer has had a fresh install since i rooted last, now when i connect with USB it doesnt even come up in device manager. Everything ive found online tells me Windows will automatically detect the device then i can update the driver. But i cant even get that far!
I was wondering if anyone could PLEASE help me figure this one out? Is there some way to force Windows 7 to install a USB driver for Nexus 7. Ive downloaded the specific driver.
I'd hate for my Nexus 7 to end its life this way.

Did you try with wugs toolkit. It should have multiple solutions for USB drivers.

I tried Wugs toolkit... also step by step, manually in SDK but Im always getting stuck at "Windows will automatically detect your device" because it doesnt.
the only solution i can think of is to get another nexus 7 to install the drivers and take it from there, but thats a leap i'd rather not take unless it's completely necessary. Even then there is no guarantee that it will work.

Are the latest chip set drivers for the computer installed correctly? All windows updates and drivers? Tried another USB device, cord, and port? Of the 5 ports on my laptop only 1 works for adb and fastboot.

When using WUG's Toolkit be sure to use the USB deview tool inside the driver section.. Remove all of the entries with the Vendor IDs listed in the tool dialogs.

Interesting that some of you have been able to get adb working. I've tried every possible USB drivers and cannot get adb working for my nexus 7, nexus 10, or Acer iconia A1-830. My phone still runs android 4.2, connects no problem. There is no solution, must be because I'm still running winxp on laptop

[Q] Bricked N7 issue

Hi all,
After a long time, I decided to play with my Nexus 7 again. About a year ago, I bricked itsomehow (don't remember how exactly).
As a result, only the bootloader is installed. So no (custom) recovery and/or ROM. Today, I tried to flash the stock rom with the Nexus Root Toolkit but it didn't work.
My computer (Win 8.1) was not able to recognize my Nexus 7 in fastboot mode.
The device manager in windows labels my nexus as an unknown device of which the device descriptor request has failed.
I already tried to install many different driver packages (while removing the device from the device manager) but it did not work for me. Everytime, the tablet is seen as an unknown device.
I also tried to update the driver manually by right clicking on the unknown device in device manager and clicking update driver software and then manually selecting this http://support.asus.com/Download.aspx?SLanguage=en&m=Nexus+7&p=28&s=2 driver but it does not recognize any driver.
So in short, my pc, which runs windows 8.1 is unable to see my Nexus 7 (which is bricked and has no rom nor custom recovery installed) when it is in fastboot mode. Therefore I am unable to install another rom.
Any thoughts on this problem? Thanks in advance.

I sent you a PM regarding this issue and a potential fix. If it works, i'll post the detailed info here later
