N4 not showing up at all on PC

I'm not sure when this problem first appeared. For whatever reason, my phone doesn't show up at all when connected to either of my two PCs. It must have when I first rooted the phone (to load ChainSU) but I'm not sure if the problem is recent or occurred immediately thereafter.
USB debugging is disabled. When I plug my phone into a computer, it attempts to install the MTP Driver and fails. When I uninstall my device, it disappears and I'm unable to manually install the driver's I've downloaded from other threads. When I load into the Bootloader, my device is recognized by Fastboot.
I'm hesitant to factory reset as this will leave me unable to root if the problem persists, which is important to me as I can get rid of the yellow tint on this screen.
Any thoughts?

Are you definitely sure usb debugging is disabled? The phone should install as a portable device on your pc. Also ensure to enter your password onto your phone when connected otherwise the phone will not show up its contents.

Make sure for windows media player to be updated to the latest, for the windows mtp driver.

There are a few things you can try. Have you tried uninstalling the drivers completely then reinstalling from the toolkit? In the past, I've had issues where the phone wouldn't be accessible in some way on one computer but would be fine on another, so maybe try a different computer to try to narrow down the problem as to whether it's an issue with the phone or the computer? Also, this may sound a bit ridiculous, but simply switching USB cables and / or ports has fixed detection issues for me in the past as well--something to consider.

Remove any existing drivers (while phone is connected), do the same for other android devices if you have any, then reboot and install Universal Naked Drivers. Have always had success with this driver pack.

100% sure on both counts.

I have this same issue with my rooted nexus 4, I've tried 3 different computers and several cables and it never connects to the PC and only charges the phone. It doesn't even give me option to choose media files.

I've had this issue before, my Nexus/Computer was acting in complete stupidity. When connecting the phone to your computer you will see a notification saying "Connected as a media device" on your phone, just touch it, and change it to "Camera (PTP)". It might access the camera for you, but It actually accessed the storage for me.

Thats not the problem, it doesn't give any option. It doesn't show up on the computer at all and only charges. It's the same for every computer.

I'm thinking we've screwed something up with the phone's side of the MTP protocol - mine is totally independent of the cord/computer used. All the correct drivers installed.
Have you tried Factory Resetting? I'm really hoping this is a workable option.

If you have a recovery back up the current Rom and flash stock and see if it's working

if the phone is locked with a pin/password/pattern unlock it.

I had same problem on my pc yesterday. Even if the drivers installer showed up that installation was successful, somehow for a mtp mode system was using some other Microsoft driver. Correct one was only used in ptp mode. So when I connected n4 in mtp mode storage wasn't available, when I switched to ptp mode everything was fine. Turn on your usb debug, switch on mtp and connect. Go to device manager in system, find your nexus there and rmb on it and manually reinstall driver. After this my n4 is visible in system in mtp mode again.

The problem is that even if I switch between MTP and PTP it still does nothing, I have tried multiple cables, computers and have reflashed the ROM and wiped the device but it still does not connect with the PC. This is frustrating.

Is yours able to connect during Bootloader/Recovery? Fastboot/ADB have no trouble recognizing my device.
It's really odd that if these things work, meaning your USB connection is fine, replacing the all of software fixed nothing... unless MTP occurs at a much lower level of the OS (maybe kernel is corrupted?)

I've got a similar problem that others have posted - PCs not detecting my N4. I got it last Friday (2/1) from Google and after the registering process and updating to 4.2.1, I connected it to my Win7 laptop and it showed on the PC as a drive. But since I couldn't copy/paste Office docs to that drive and had to do that through Dropbox, I didn't bother trying to reconnect until Monday, at which time the PC didn't detect it. Neither will one other Win7 nor two XP (both with WMP10) PCs. Have tried multiple cables, all of which work with other Android devices (pre 3.0). I've seen several suggestions on this and other threads, but one major issue I'm having is that some of the fixes require enabling USB Debugging. For the life of me I can't find that option in the N4's Settings. Unlike my other phones, there is no Applications subcategory under Settings on my N4 (4.2.1, Build JOP40D). Can anyone help me find that option? TIA.
Edit - Found answer. Click on Build in About Phone setting 7 times. That activated Developer options. Now to try the fixes which require USB Debugging mode turned on.

[Q] USB Debugging Not Working

I've googled and searched everywhere for this, but no luck. I got the S4 yesterday (AT&T) and i went through the steps to turn on developer options for the new 4.2.2 jellybean to get access to the USB debugging option. I turn USB debugging on and hook it up to my computer and it will not install the ADB interface driver (needed for PDAnet). The phone connects as if USB debugging is not turned on saying "connected as a media device" and keeps giving me the option on the computer to access storage. Anyone or everyone else having this problem?

Did you install the drivers? Did you have the phone connected when you enabled it? If so disconnect and reconnect.

I did the same thing and it worked for me tho..

Also, you may want to check your phone's screen after you connect it to the computer. I had to "accept" my computer's RSA key before adb could detect the device.

I've done everything and tried everything I know to. I have restarted the computer, the phone, enabled and disabled usb debugging while it's connected to the pc and no conncected. I've installed the drivers PDAnet says to, but still my phone connects as if usb debugging is not on (says connected as media and pc doesn't recognize and install the adb driver). Is there anything I'm missing?

All I did was install install the S4 drivers from Samsung. Enabled USB Debugging. Plugged it into the computer. Waited for the drivers to finish setting up. Disconnected and reconnected again just to make sure drivers were loaded. And launched ADB. Nothing else.
Edit: Oh almost forgot. I got a message on the phone saying something about a computer trying to connect do you allow it. I hit always allow or something. Sorry don't remember exactly was too long ago. That is probably it because if you weren't watching the screen you wouldn't see it.
Edit2: LOL just saw captawsm's post. Yes what he said.

You guys on AT&T? I never got that message. I know nothing ever popped up like that. Did you get the actual driver from Samsung website for your phone? I just tried installed the one pdanet offered.

I did not install any other drivers tho..it was all default but it did ask me to confirm the computer's RSA key

Hallelujah! I finally got it working! It must of been a driver install quirk on my pc. For anyone else with this prob who used a previous phone with pdanet on the same pc like I did ( I used a samsung infuse prior). I went and uninstalled the samsung drivers that were already on my pc and then went to the samsung site and installed the newest ones they had. Hooked the phone back up and after about 6 or 7 seconds (have no idea why it took so long) the drivers on the pc started installing again and cha ching usb debugging was working correctly. The RSA thing popped up after that.
Thanks guys for assuring me it was only my problem and not a mass-wide problem to make me troubleshoot further.

I've been having the same problem but can't seem to find the drivers on the Samsung website. Could you please post the link?

If your computer recognized (and installs drivers) when your S4 is connected via usb (not in developer mode) but does NOT recognize your S4 when connected with USB debugging this is what you might need to do. It took me 2.5 hours to find this.
Remember to have your phone set to MTP + ADB mode.
to do this:
in phone mode type *#0808#
Choose : AP on upper part and
for USB Setting, choose : MTP.

[Q] PC/Laptop No Longer Recognizes S4

The device is stock. I am using the stock USB cable and have tried both my PC and Laptop to no avail. I have tried installing the USB drivers from samsung.com, updating Kies and everything. I have tried every single USB port on my PC and on my Laptop, none have worked. It sometimes says the driver has been successfully installed, but then Kies says I should try Kies 3 which then says its an unsupported device. I am so stuck. Thanks for your help.

If you can live without kies uninstall it. It'll interfere with your usb drivers.

Go into device manager, view, show hidden devices. Then delete all the usb devices that are greyed out. This is kind of a pita. Then reboot your pc, then let it find your device by plugging in the usb cable.

Rebooted. Still nothing.

Get a new quality cable.
Does the USB icon appear at top of phone. If so, pull down menu and tap on the usb listing and select a different connection and see if that works, like camera etc.
It could be a hardware issue. Take it to a store.
Is USB Debugging selected on phone?
You could after all else fails, Use a wireless app to back up personal phone data and do a factory reset. Even using MyBackUP pro and putting backup on ext sdcard.
Maybe even pull sdcard and pull battery and reinsert/rebooot with no sdcard.
Kinda grasping on some of these ideas--

One last thought. Are the usb ports 2.0 and not 3.0? 3.0 don't work.

MTP Mode not working

Hey,
So I got my D802 today and I want to do the whole Root, Recovery, ROM shenanigans.
But for the love of god I cant connect the phone in MTP mode, so I cant Root, nor install a recovery.
I cant connect to the LG PC Suite either.
Any Ideas?

what connection type are u choosing after plugging it into the computer? are u running Windows, Mac, Linux? Windows will work with mtp out of the box but I think Mac and Linux need phone drivers installed. Windows will need drivers when you're ready to "unlock" using adb.

when you first plug in your phone it gives you the option to install the drivers needed to connect in the different modes, if not on the top right corner of the menu with charge/mtp/pc software it should have the option to install the drivers

you never said what connection type you're choosing on the phone after plugging it in. there are a few options and change how the phone is seen by Windows. some options won't have it display as an mtp device or as a drive letter in my computer.

Really Weird
I'm having the same issue. I'm running OptimusG3 v1.3, I've never had an issue with it before, I used MTP to transfer files yesterday, worked flawlessy, now it won't. I was trying to map the G2 as a network drive, I installed LGPCSuite, a couple of other software that should be inconsequential, and suddenly my phone says connected as MTP, but my laptop won't recognize or show the device in My Computer. I get installing device drivers prompts, I used the hardware and devices troubleshooter which told me 'LGE Android MTP Device has a driver problem' and LGE Mobile USB Modem has a driver problem. Reinstall device driver -> completed, but still not fixed. I installed LG's universal uSB tool or whatever, no fix. I have no idea wth is up (It's not a USB debugging accidental toggle either). I'll try uninstalling PCSuite. I though it would be more useful

USB doesn't work after OTA

Hey all,
I have tried to google and figure this out but my phone doesn't show up in device manager in windows or in android file transfer on mac EXCEPT when in download mode or when the phone is off/charging via my computers USB port.
So when in download mode, the phone shows up in device manager....
When my device is off and charging via USB port, it shows up in device manager...
I have tried USB debugging mode no change...
Charges just fine. No usb port issues because it connects during download mode etc...
During these times, i obviously can't access the SDcard.... but as soon as the device boots, it disconnects and disappears from device manager even though its still charging etc...
This only happened after the last OTA update.
I assume i will have to restore to defaults as its probably an issue with the kernel and usb protocol but I dont have the phone rooted and i don't want to root it at this time... I am hoping there might be a quick fix and/or setting i am missing.
Thanks!

You do have to have USB debugging mode checked. If you don't have the developer option enabled in settings, go to about phone, find your build number and tap on it rapidly until it says your developer option is enabled. Back out and you should see a developer tab. Click it and make sure USB debugging is checked. If that doesn't work you might reinstall the latest USB drivers.

i did both of those. the odd part is when in download mode windows chimes that my device it attached.. no problems right? but anytime the android OS is running no chimes at all no recognition at all on any computer... its almost like back in my linux days when the kernal had a usb module failed to load... i swear its as if the kernal turned off usb data communication... power is fine... just wont communicate unless in download mode or in a power off state.... totally weird...

When you plug it into the computer, pull down your notification drawer, make sure USB setting is set to MTP. It usually is set to installer, or charge only by default.
Also I'd say completely wipe out your phone drivers on the computer, and reinstall all new ones.
Possibly reinstall ADB as well.
