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 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.

Yes.

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.

And about the recovery just try flashing another recovery from fastboot

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.

Nexus doesn`t appears in device manager. At all. It starts to charage, but no reaction in device manager, no any reaction(except charging) at nexus. On computer it looks like i didn`t connect anything. I`ve trying to intall drivers as legasy hardware, but nothing changes. Sorry for my english.

KitKat on Nexus 7 Failes

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.

[Q] Nexus 4 gone stealth

... 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.

Nexus 4 will not show up on Computer

Nexus 4 when plugged in with 2 different cables (both capable of transferring MTP as tablet transfers files and connects as MTP just fine) don't do anything and just charge the phone . No "connected as a media device" notification. Checked settings and it's on debugging mode as well as MTP mode but still not being recognised and the same applies for PTP. Phone has been factory reset and still does not get recognised by computer. Device Manager doesn't pick up anything either. No ADB, Nexus 4 name in Device Manager. What's the problem and how can i get it to show up on computer as an MTP device? The phone's not rooted and is Android Version 5.0.1 Lollipop.

If you want to use MTP, it is supported in TWRP recovery.
Boot into TWRP recovery and you can view and transfer everything in N4 /root via windows explorer on PC.

If your bootloader is unlocked, you can flash or boot into TWRP recovery, it supports MTP.
If you have any connection problems between PC and TWRP MTP, it is likely driver related.
You will need to look in Device manager on PC while phone is connected.
Download the howto_driver.zip from the "15 seconds ADB Installer thread" and follow the picture tutorial contained in the zip file. This should fix your connectivity issues.
If you are sill having connection issues, You could try and install ADB drivers . It might help the pc detect.

Then go back through the picture tutorial in the howto_driver.zip
