Halp! Windows 8.1 upgrade at war with n4 - Nexus 4 Q&A, Help & Troubleshooting

Hi,
I had win 8 in which I was successfully able to do everything with my n4 (adb connections were good and so was MPT). I updated to win 8.1 and now it's derping out. ADB drivers seem fine. I tested it by simply running adb shell in cmd prompt, but even though my device is connected, it says that it's unable to find device.
Whats more important to me is that the device is not showing up in my computer. Although windows plays the usual usb connection sound. I'm also able to see it has detected my device as Nexus 4 is under the unknown device category. How can I fix this. I relly need to transfer a few things between the comp and phone, and it kinda sucks at the moment.

Just format it and install Ubuntu!!!
lol, just jocking. if adb is working you don't need it to recognize it. You can just use adb push/adb pull, but anyway.. did u try to enable debugging?

It means something has derped with the mtp driver
Open up device manager
You will see your nexus 4 with a yellow exclamation mark next to it
Right click and update driver
Manually choose
Then you will have to scroll through the list and find the mtp device (I can't remember of the top of my head exactly which headers it is under)
Sent from my Nexus 4 using xda app-developers app

Connect your Nexus 4 in USB debuggin mode and uninstall your current driver in device manager checking the 'delete the driver software' option.
Download Universal Naked Driver: http://forum.xda-developers.com/showthread.php?t=1379875
Reboot Windows 8 into advance mode and select to disable driver signature: PC Settings -> Updates and recovery -> Recovery -> Advance startup -> select F7 option at the selection menu when you see it
Reconnect Nexus 4 and install it with UND driver.

Thanks all! I just uninstalled the current drivers and reconnected the device. Windows picked up on the right drivers. All ok!

Issues with adb shell, etc.

So for the first time I've set up my ADB since I will getting a MT3G tomorrow. Environment variables (PATH) set correctly, etc.
When I type adb shell in recovery model, it says *daemon not running. starting it now, daemon started successfully, error: device not found*
"Android Compsite ADB Interface" shows up in my USB devices. So what's the problem.
Then when I load up "emulator -data c:\", it starts up and gives me this error. msvcrt.dll? I've dealt with that .dll file before for other apps and it is in my system32 folder.
So what's going on here.

try reinstalling the usb driver.
mine identifies as HTC Dream Composite ADB Interface.
did you install the usb driver that comes in the SDK?
what if you navigate to the location you have the sdk installed? does it work then? maybe the path is not set up as correct as you think? (i had this problem when trying to do fastboot. everything else worked fine except for fastboot. to get that working i had to navigate to the sdk directory.)
I sure did, and it reads exactly that.
Even adb devices doesn't bring a device up. Or adb remount.
Other thing is under Hard Drives Tree, the HTC Android USB Phone Device has a Microsoft driver. I tried to install drivers from the android/usb_driver/ and nothing. Do I have to do this in the Home Screen for the first time so it brings up the permission screen where I click on "Allow Always" for root? Cause I'm not getting that there, so I rebooted into recovery....nothing there as well.
i did have an issue recently where i couldn't get the usb driver to change over.
what i had to do to get it to change was disable and then re-enable usb debugging while the phone was connected to the computer.
it triggers a hardware change in windows and this allowed me to reinstall the correct driver.
uninstalling the current drivers might also help.
I've tried both things.
Same issue.
What Windows Services need to be enabled in order to get ADB to work? I did some tweaking of the services.msc for XP. I think that might be the reason adb shell isn't working.
Same problem I have:
I have TWO rooted G1s, Cyanogen 4.0.4 modified devices with identical Software releases.
The one (rooted by the Golcard Method) is recognized by ADB - the other one (rooted by the One Click Method) is not.
Troubled !
Oh Sorry -this is a Sapphire forum ... I apologize

[Q] Why won't adb recognize the Nexus 10?

adb isn't recognizing the Nexus 10 on Windows 7 or Ubuntu 11. Here's what I've done:
Installed the SDK and USB driver from Google. Windows 7 sees the tablet as an 'Android ADB Interface' under 'Android Device.'
Put the tablet in developer mode by clicking on 'About tablet' and clicking the build number seven times.
Put the tablet in Camera (PTP) mode by going to Storage > USB Computer Connection.
Started and restarted the tablet, my computer, and the adb server.
On Linux, I've done the following:
Installed the SDK.
Added the vendor ID "18d1:4ee5" to ~/.android/adb_usb.ini
Created a file /etc/udev/rules.d/99-android.rules.
Restarted my computer, udev, the adb server, and the tablet.
Here is the content of 99-android.rules:
Code:
SUBSYSTEM=="usb", ATTRS{idVendor}=="18d1:4ee5", SYMLINK+="android_adb", MODE="0666" GROUP="plugdev"
TEST=="/var/run/ConsoleKit/database", \
RUN+="udev-acl --action=$env{action} --device=$env{DEVNAME}"
Am I missing something? Thank you.

Did you turn on usb debugging in developer options?

No, I hadn't! I thought the seven taps on the build number put the tablet in USB debugging mode. But you're right - you have to do that separately.
Thank you. Everything works now.
I have done everything that you have done but windows 7 won't recognise the nexus 10 weather in developer mode or not. Any help?

TRY THIS:- Works like a CHARM!!!
http://koush.com/post/universal-adb-driver
Be sure to "Allow ADB Debugging" on the device not just turn on the developers options.
You need to accept the security notification on the device itself because if you don't no driver will ever work.
Boot pc, boot device plug device on leave screen active, attempt adb and on the device accept the adb connection permanently.
This is a new security feature introduced in adb and you must use the most current version of adb as well.

[Q]PC cannot identify Nexus 7, no driver? Charging when USB is connected

I recently bought a Nexus 7 (2012 - WiFi Version) on eB*y, the Device is Rooted, ROM is CyanogenMod-NIGHTLY-Grouper.
When i tryed to connect the Nexus 7 with my Laptop and PC it started to charge (but verry, verry slow) and i Windows says that the USB device cannot be identified (also i cannot install drivers for it becaus it cannot be identified) Fail-Code is: 43. I tryed it on Win7 Desktop PC and on a Win10 Laptop but no chance.
Also i tryed to install a Factory ROM via Recovery Mode (from SD Card) it says: Installation aborted.
I really dont know what to do now? I think it is the USB Flex Cable, what do you guys think?
Sorry for my bad English.
Hope someone can help me here.
On your Nexus 7, search for a setting called USB connections and ensure MTP is checked.
On your windows PC, Control Panel > Device Manager, go to your broken Nexus device, right click and update the driver for it... Select you want to install the driver yourself. Then it will ask you to browse to the driver, but underneath that you will have another selection along the lines, "select from common driver list". From there, look under portable devices and select either MTP Storage or MTP USB Storage. I had the same problem and only MTP USB Storage works for me.
For ADB and Fastboot stuff... Search these forums.
Hope that helps.

Don't forget to try other USB cables.
Just use the Nexus Root Toolkit and follow the easy wizard to completely setup the N7 on your PC:

[GUIDE] Fixing Windows 10 doesn't recognize MTP mode when USB is connected

All right, so you have updated your phone's ROM or you have purchased Windows 10 Pro, you plug your USB cable from the phone to the computer. Phones get charge, if you choose PTP (to transfer photos) it works, but if you select MTP or USB storage you hear a sound like if you had disconnected the cable and phone is not recognized.
This is related to a driver problem. To fix it:
1 - Plug the USB and select MTP connection
2 - Go to your Device Manager (Press Win+R, on the search box write "mmc devmgmt.msc" without quotes). You can use any other way you know to enter D. Manager.
3 - You should see something similar to "Portable devices". Display the flange (if not).
4 - Now right click on something similar to "Unknown Device" (yellow highlighted text) with a yellow tringle in the icon.
5 - Choose "Update driver software"
6 - Select "Browse my computer for driver software"
7 - Select "Let me pick from a list of device drivers on my computer"
8 - You get a list with a lot of possible drivers.
9 - Choose Mobile Devices/Android Phone/Android USB Devices (you should have at least one of them)
10 - Select "MTP USB Device" from the second screen's list of drivers.
*If you do not see Portable Devices in Device Manager then maybe you don't have installed drivers properly. In that case, first download drivers from here and install them. Then follow this guide.
Some screenshots of the proccess (it is in Spanish but what you have to do is the same and is translated in the steps).

That is the most common solution to the problem. If your problem is not fixed with that, then try this:
Published on Microsoft Answers:
Question:
After anniversary update, MTP is not working.
I tried with different devices as well as on many PCs.
In device manager I get this:
The drivers for this device are not installed. (Code 28)
A service installation section in this INF is invalid.
Click to expand...
Click to collapse
Solution:
1 - Go to C:\Windows\INF
2 - Type "wpdmtp.inf" in search bar provided to the right of the address bar in Windows 10.
3 - Once you found it, just right click on it and select install. It will take a very few seconds.
4 - Connect your device to the pc. It should be recognized now.
I hope this can be useful for you.

Google Nexus 4 MTP mode not recognized by Windows 10 (Manual Fix)

Hello N4 Owners/Users.​
lately I've been working on IOS & iCloud Activation Lock Security, which is a Job I honestly do not wish you have, because is not a great business at all but, going more deep in this post I'm glad to post it because I've been trying to send iCloud Accounts stored on a PDF at my Nexus 4, a device that I've purchased last month at eBay and is incredible how this device with Unofficial ports runs faster and without bugs, of course using PURE Nexus ROM.
first things first, I must specify that I was sideloading ZIP's, APK, ROMS through ADB SIDELOAD commands, so that the first sign of a properly working USB Port, I didn't noticed yet that I was unable to set up my device as MTP and transfer photos or WhatsApp Folder to my PC.
2 weeks later I've noticed that MTP was not working, even changing "Charge Option" to "Transfer Files" so I just put my knowledge on going, the first thing was download the USB driver at Google SDK webpage, which delivers USB Drivers apart instead with the whole SDK, I've just proceed to download it, I've installed it and for my surprise the MTP was still not working...
what do now ?​
Steps:​
1. Download the proper driver designed by google
Google Nexus 4 Drivers.
2. Make sure your PC is not on secure boot, for this you should reboot your PC and enter to BIOS Setup to make sure secure boot is not activated, if it is, please turn it off.
3. reboot again and let your PC boot, you may notice that the boot sequence UI display a little messed up, but is normal.
4. go to UWP Settings and Select "UPDATE & SECURITY"> "RECOVERY"> "Advance startup" and hit at "Restart Now"
5. your PC is going to restart again & you'll see a menu of likely 10 or 9 options, we need deactivate the option 7.
7). Disable Driver Signature Enforcement.
Click to expand...
Click to collapse
doing this your PC will restart again or maybe it just boot the Windows or UEFI Logo.
6. Find & Run CMD as administrator and execute the code below.
bcdedit /set TESTSIGNING ON
Click to expand...
Click to collapse
Restart your PC Again.
wait, you need the MTP or really are you craying for such restarts?
okay, that's what I though.
7. Disable ADB on your device and connect it to PC, Open device manager and look for "Android ADB Interface"
8. Right Click on the device and select "Update driver", Select "Browse My Computer for driver software"
9. locate drivers folder you've already downloaded following this guide and after that, you must have this screen

}
Select "Let me pick from a list of available drivers on my computer"
If are 2 MTP entries, install them and reboot your PC, and that's all people, MTP working.
Now go back at CMD as Administrator and set this
bcdedit /set TESTSIGNING OFF
Click to expand...
Click to collapse
Now Restart and enter at BIOS, restore secure boot, done!
Hit "thanks" button if this helped you recovering MTP Access and your PC at your N4.
