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

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.

Ever since I rooted I can not get my Epic to connect to a computer period. I'm about to give up and just deal with what I got, hopefully someone can tell me what I'm doing wrong. Before anyone decides to be a smart ass I have used the search function literally for days and have tried tons of things recommended with no result. I am the first to admit I'm an idiot when it comes to anything involving computers but I'm pretty determained to learn.
This has to be the phone because I have tried to connect to 2 desktops (1 running Windows 00 and 1 running the most updated Ubuntu), and 3 laptops (Windows xp, Windows Vista and Ubuntu). When I rooted I used the Vista computer and connected fine (can't anymore). I didn't have the space on the C drive to install the Android SDK so I switched to Ubuntu (first time user btw lol). Somehow when I was backing my SD card I lost any access to it or the notification bar. I never got my SD back til I rebooted but I haven't been able to connect to any PC since. When I charge (even in the car) it always tries to stay in mass storage mode. I basically charge in my car with my phone off hoping it will just charge and not mount my sd card to my car or wall lol. Yes I wiped 3 times, partitioned sd, tried several different cables (but my husband used mine and no problems on his Motorola) I'm sure I've done something wrong when I rooted or mounted to Ubuntu.
I also can't use adb. I followed the directions to the t (a few times lol) but when I run any commands it says "no such file or directory" I didn't have adb on the windows pc when I di noobnl's one click so I never ran the (adb shell ect) commands. I now can't do jack. I am now running noobnl's DI18 ROM with modem.bin flashed thru Clockworkmod.
I have tried all the basics you will find wit 2 days of web search.
My goal is DK28 (dream on Erica lol)...Thanks for any help and for anyone sparing me a lashing ;-)

When you plug in on your windows pcs...in Device manager..do you see anything appear? also do you have USB debugging on the phone?
USB debugging on?
Have you tried reinstalling the drivers for the Epic?
Rebooted phone and PC? (Sometimes it helps)
Used Odin?
Something might have been screwed up during one of your downloads, bad file maybe. Try reinstalling your drivers first, use Odin (phone must be in download mode), and see if it recognizes te device. If it does then Odin the stock .tar file and go from there. It'll give you a fresh start.
That's all I can think of right now.

I bet your USB debugging is on since most root's requier it. Even tho it says connect to pc if usb debugging is on it wont connect to my windows 7 box
I would suggest, if you're really having this many issues, just boot into download mode (1 on the keyboard + power button) and odin back to di18.
Just for kicks have you tried Settings > Privacy > Factory data reset? I assume that wiping does the same thing if not more but it's worth it to see if it somehow resets a setting that might be the issue.
What's left - software issue or Hardware issue.
Software:
hmmm...yeah gotta try connecting through Odin which uses downloader mode instead of USB modes...
Can Odin see your phone? Run Odin as admin with antivirus off, and proper samsung drivers installed. Then boot phone holding down 1 key into downloader mode. Connect to computer through USB port on back of computer (i.e. directly to motherboard) - does Odin identify something attached to USB port?
Yes - flash the dk28!
No - with Odin still on, unplug the USB cable, pause, and reconnect it. Still No? Try a different USB port on computer. Also try uninstalling and reinstalling the drivers - be sure to reboot the PC. If still No, then try on another computer, and as you did before, try different cables. Still No?? --> hardware problem with phone.
Hardware problem with phone: Look at the usb port in the phone - is there any junk in there that might interefere with the connection?
Yes - clean it out
No: phone perhaps internally damaged:
Solution for hardware damage:
You and husband clean up and go to sprint store.
At store - tech will know phone is rooted, so:
--Tech more likely to like you? You handle it, maybe even blame husband. Husband can silently attend and look sheepish, playing the part of 'me man, me dominate environment, me break fancy tech of wife, me sorry." Try to get free replacement phone while simultaneously promising never to let your husband root the phone again, or even touch it.
--Tech more likely to like husband? He goes alone, cops to the true story of how you rooted it and then was backing stuff up when it suddenly stopped working [truth from men? so sincere!]. Try to get free replacement phone while simultaneously promising not to let you in the house should you even attempt to root again.
P.S. forgot to add you might turn off the PCs firewall while testing, as well.

same here. I tried out the free tethering app the other day and with usb debugging on i coudl never get it to install the proper drivers. Without it on and the 64bit drivers installed Odin worked just fine.
I have seen many Galaxy S devices not connect to a computer because of a faulty USB cable. Had my girlfriends sister switch out 3 Vibrants only to accidentally try and connect it to a laptop with a different USB cable and I've seen two others not connect with the stock Samsung USB cable.
How I fixed the tethering issue
I've had the same problem with my galaxy s - connecting to the PC (Win7 32bit) just doesn't do anything. As a test, I had a friend with the same phone/rom (froyo, rooted) connect - and he was able to! It installed the drivers and it just worked. He disconnected, I connected, and now it's fine.
So, see if you can find someone with the same phone and see if they can connect. Makes no sense to me, but it worked.
I've had my Epic fail to mount before. Interestingly any time I had an issue it was with a Mac - it always mounts on a PC. I'll stop now before I open up a can of worms.
Best advice I have is get a Dropbox account. You can use that guy to move files from a computer to the SD card without having to mount to the computer. Perhaps you can get a factory ROM (with root of course) on your phone that way?
You can get a app from the market called SWIFTP (free) & connect to your sdcard via ftp server. This can be a temporary fix till you get your connection error resolved.
I have 1 USB port on my laptop that the Epic shows up as "unknown device" on. Works on every other port, and everything else works just fine on the same port. The factory USB cable is finicky!
When I plug in my nexus4 to a computer it wont show up...most of the time.
I've used 3 different cables.
4 different computers, running, linux mint, win7 and XP.
I installed clocwork mod recovery today and then it showed up as a new device on a XP copmuter but then it would never show up again.
I'm rooted, running carbon ROM, usually with TWRP recovery but switched today.
I've tried it in MTP and PTP modes, debugging on and off.
it charges just fine from a PC.
any ideas are appreciated.

For some of the computers. Today I'm at work and I don't have the drivers installed. I keep my phone plugged in to charge. In the past the PC, running windows XP, always pops up the new device found notification. It won't even do that except for the 1 time mentioned earlier.
it it possible for the recovery image to affect things?
Mine won't show up in my PC (windows 8) If USB debugging is off. I'm fairy certain this behavior started at some point during the rooting process because I had a hell of a time getting the files to the phone.

From what I noticed, when you use a lockscreen with some kind of protection the device memory will not show up if it hasnt't been unlocked in the past few minutes or before connected. This is mostly for security reasons to make sure you are the one accesing the device..
I am not sure if this is the source of the problem you are mentioning but just to let you know
That's not it, I'm doing this with it right in front of me, unlocked

Have your nexus connected and disable developer settings and delete your adb driver. Then select mtp mode while connected and you should be able to connect now.

FWIW, I have encountered odd connection issues with my Nexus 4 running bone-stock Android.
As I recall, it won't connect to ADB in MTP mode. In PTP mode, it usually works. Personally, I just said "screw it" and starting using MyPhoneExplorer for everything.
Enable USB debugging in your phone. Nuff said.
nothing works, PTP, debugging on/off, etc.
well I finally got a hold of my wife N4, it connects just fine. so I think it's definitely a hardware issue.
Ifixit shows how to replace the daughter board.....but I'd rather send it to LG for warranty replacement but I have it rooted.
If I could just get it to connect once more I would flash it back to stock.
For some reason, I can no longer get any computer to recognize my Nexus 4 when connected by USB. I can charge but cannot get the phone recognized.
A couple weeks ago, everything was working fine. I was running Cataclysm (November build based on 4.3). I upgraded to the Nexus 5 and decided to give the Nexus 4 to my daughter. I was able to connect the Nexus 4 to the computer and move all my photos and music etc off of the phone. After moving my files off and doing a Titanium backup and Nandroid just in case, I did a complete wipe on CMW (6.0.3.5). Everything fired up fine and I had no reason at the time to test the USB.
However, last week, my daughter was complaining about bad battery life and I decided to take a look and go ahead and update the phone to the latest (Dec. 12) Cataclysm build based on 4.4.2. Before flashing the new build, I connected the phone to the computer by USB but could not get the computer to recognize the phone. The phone charges, but is not recognized in device manager and does not connect.
I've done everything I can think of to troubleshoot the issue - all without luck - including:
Turned USB debugging on and off. No luck.
Changed the USB storage mode from MTP to PTP and back. No luck.
Confirmed fast charging isn't somehow enabled. It isn't.
Tried several different USB cables. No luck.
Tried a different Nexus 4 and my Nexus 5 on the same computer. They work.
Tried the subject phone on a different computer running Windows. No luck.
Tried the subject phone on a computer running Mac OS. No luck.
I did go ahead and flash the latest Cataclsym build (I did a full wipe again) but sill no change. I don't see any evidence of physical damage to the micro USB port but I took a small toothrush and gently cleaned the contacts with rubbing alcohol.
At this point, I believe the problem is either the a) the port is bad or b) somehow, the phone software/ROM is screwed up.
Is there any way to determine whether the physical port is bad? Any other ideas. I'm kind of at the end of my capability here.

I don't think I've got the same issue. I cannot get any computer to recognize the phone under any mode (storage, photo, debugging on, debugging off). Nada. At this point, I'm pretty sure it's the port gone bad. I just wiped the phone again and clean flashed the stock 4.4.2 ROM, radio and bootloader. Still no connection.

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

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
... 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.
