Hi guys. I ran in to an issue I've never experience before, for some reason my Nexus 4 is no longer recognized when plugging in a USB cord. It was working fine like 2 weeks ago and I made no changes since then. Everything is pure stock with unlocked bootloader, no root and I'm on Lollipop which was updated via OTA with no issues plus I did a factory reset right after just to make sure. I tried everything that has been mentioned in other threads, made sure MTP was checked, USB debugging off or on, updated drivers on my computer, changed USB cords, rebooted phone, booted in safe mode and here's the thing, it isn't even recognized by my car stereo when it was working fine 2 weeks ago. I already made sure it wasn't the stereo because I plugged in a USB driver and it read it right away. I started to think that maybe the USB port on my phone went bad, but it's charging fine so I'm like clueless to what could be wrong right now. I only have 1 last thing that I could do and that's to do a factory reset, but I'm trying to avoid that so if anyone could help me in anyway I would greatly appreciate it.
Turns out that it is in fact the USB port, I noticed it was pushed back past where it's supposed to be because of an indent or line of where it used to be in the inner opening so I started to wiggle it around with the Xbox One controller USB charger that I have which is newer and grips more when plugging it in and I got a reading finally but it didn't last ?, I think this cable is what pushed it back farther and now I can't get it any closer without causing damage SMH, just when I was starting to like my Nexus 4 all over again. Oh well on to the Nexus 5 then faster than I expected.

The first thing I tried to do when getting my Vibrant 2 days ago was to try to install drivers, wasting hours and hours and getting nowhere (all I wanted to do was to copy the rooting zip to root the phone). Yesterday, I tried turning off my USB Debugging, and then mounted the SD Card(s), and they both worked as they should. Great, so I can get my computer (Windows 7 32bit, FYI) to recognize the drives and copy files (by then, I had already just copied the file I needed to via just taking the SD card out, phone has already been rooted, but now I was thinking about tethering).
So today, after having done a lot of searching the past 2 days, and having come across a post I found on another forum (sorry, I'll have to go do more searching to find it again) where someone suggested that one of the issues might be the USB plug on the computer not being a powered one (this was front USB port on a Gateway computer), I plugged the cord into a powered USB hub I have, turned USB Debugging back on, plugged the phone in, and the driver install went a bit further than it did before, at least recognizing the device, but not installing the drivers. I went into device manager on my computer, pointed the 2 unknown devices to where the Samsung Drivers I downloaded off of Samsung's website were and everything installed perfectly. Phone is now recognized when plugged in, and the SD Card(s) mount just fine.
Since that was a major reason to keep/return the phone, I'm happy to have discovered the solution to 2 days of research. I thought I'd share this in case anyone else might be having issues with installing drivers for the phone.
Now to see about the battery drain and some other potentially "minor" issues and see about it really becoming a keeper (coming from a MT3G, it is a major upgrade, so it's just getting used to the differences).
I had an issue with USB Debugging on too.... so I thought, then I realized I was using the Nexus One cable and not the Vibrant cable. I turned off USB debugging and used the proper cable and everything was automatic.
Interesting read, thanks for the post. Perhaps I need to tweak the sticky some.
edit: added this thread to the sticky. Thanks man.
Interesting note about the different cable options, I had read that some cables were "better than others" - I had to use the micro USB cable that came with the Vibrant, so I knew that wasn't an issue, figured I'd tried everything else, so what the heck (thought I swapped the USB plug last night, but turned out I swapped the wrong cable, lol).
I did order a bunch of generic micro USB cables from ebay (2 different sellers), but I just need those for charging (like for the car, for my travel back, etc), I'll stick to the Samsung cable for data needs and likely test the others in case I need a backup.
Your main thread was definitely helpful, and I just wanted to share a potential solution to an issue I had seen others post about without any resolution (actually, the person in the other thread had a slightly different problem than me, and never claimed solving it by changing to a powered USB plug).
USB debugging no longer activates on my phone. Activating it in settings/applications/development brings up the "Allow USB debugging?" permission window. However, no usb notifications appear, and the phone appears to be a dead device to any PC it is connected to.
This started when I accidently got into the download screen from the phone options popup. The display showed the yellow sign, android guy with shovel, and message warning not to turn target off. Phone was not connected to anything at the time.
Searching found a couple of threads indicating that a battery pull was safe to get out of it. Did same.
Since then, usb debugging (or usb anything) has been dead on this phone. Other methods of usb access (thru usb settings) have no effect either.
Tried the following...
(1) restore to my last backup rom.
(2) numerous reboots and battery pulls.
(3) mount/unmount sd card in cwm recovery
(4) clear caches
(5) changed pc's and cables (all worked before)
(6) reinstalled usb drivers on pc (worked before, didn't expect it to help since issue is at phone end)
As you can see, I'm running out of sticks to poke the horse with. Does anyone have any ideas?
Update: new kernel didn't help, either
Update2:
(a) Can't do a restore via odin, which won't detect the phone.
(b) Updated my adb (which I don't use much). adb devices command will not detect the phone via usb.
(c) Installed adbWireless which allowed me to push a stock nandroid backup to the phone. Restored that, usb is still dead.
(d) Restored back to my superdark rom, usb is still dead.
Head scratch: I'd blame hardware except that it seems to be between the settings and execution. If it was purely hardware, I'd expect to see the usual usb notifications. Regardless, it looks like I'll have to revert back to stock and let Verizon figure it out.
Update3:
(a) switched to the new AOSP rom. Nice, but no usb.
(b) switched back to superdark since I like my speakerphone and the AOSP seems to be on hold. Still no usb.
Resolution:
My apologies for not posting a resolution. My bad. After the first few days the post kind of fell off the radar and I stopped checking.
Short version...dirty usb port.
Details...after a week or so, I saw the usb icon flash in the notification bar for a few seconds when I plugged it in for a recharge. Hadn't seen that in a week, hope springs eternal!
A thorough cleaning of the usb port using a paper swab dampened with alcohol restored usb functionality. Not much dirt came out on the paper, but it must have been enough to probably bridge the contacts somehow.
At present the phone is fully functional. The original Verizon cable seems to be a little wonky. I have an aftermarket cable that works fine. It may be that the aftermarket cable did some physical harm to the contacts in the port, or the original cable is going bad (I had something very similar happen on my Omnia). Not sure.
I now use the original verizon cable only for charging at work and use the aftermarket cable for usb connecting at home.
Bottom line...if your usb goes dead as described in the op, carefully clean the port.
My thanks to all who responded...
Download screen shouldn't have harmed you.
You probably are well aware of this, but sometimes it's the simplest solution: Is your usb cable unplugged when you are trying to turn on USB debugging? It will not let you if you are plugged into a pc or mounted for some other reason. Make sure your file manager and any other rogue app is closed. Again, it does sound like you have tried all of this, just giving my best shot ar an answer.
Other then that... Has anyone else had this problem? I haven't seen it in this forum before.
The most general solution to any issue on these fascinates is to undo whatever you did to break it, it's just difficult sometimes to isolate what that event was.
Swyped w/ XDA App. When in doubt, mumble.
Thanks for the reply.
USB is unplugged when turning on debugging. I've also tried turning the phone on with usb plugged in.
The last thing I had done (before accidently activating the download screen) was to install SiMi Folder Widget. Needless to say, it went away with the rom restore.
Also used ATK to kill running processes before turning on usb debugging. Also verified that I still have root.
I've buggered the phone up before but have always been able to figure out a way back (with help from forum searches). This one's got me stuck.
Tonight I'll try to figure out if it can be odin'd back to stock and rebuild from there.
Again, thanks. All suggestions/advice are appreciated.
See op for steps taken to (unsuccessfully) solve this.
Can anyone advise how I can flash back to stock DI01 without using odin, since it won't detect the phone? I can push files to the phone via adbWireless but that's about it.
thanx in advance...
I dont know if you fixed it or not, but here is a stupid question. Are you using the cable that came with your phone? I have several cables that will only charge my phone and only the stock one enables data transfer. Hope this helps. Good luck

This may be my problem! I'm having the same similar effects. Although mine randomly shows the symbol but also says my usb is connected when it does. I've been trying to solve this for 2 weeks now! I hope this is the solution.

common problem
This must be a common problem because I've had the same issue. switched cables and viola, all good.
My exact problem solved:
USB debugging activated on phone but computer did not detect it at all, nothing what so ever. Not even on dial-up mode, or download-Odin (yellow triangle).
Drivers installed (Fascinated and Nexus for the hell of it).
Tried to ADB my into it both from windows 7 and MAC OS-X.
Hell I even tried a different USB cord.
I would get the USB debug icon in the status bar only when on windows7 machine.
I cleaned the phones USB port with the alcohol damped paper towel/tooth pick and the **** worked, first time.
Man I gotta thanks God for this site. I been ****ing with for 2 days.
Then this lil SOB acted as if nothing ever happen. I wanted to beat the hell out the lil ****er. But we are back friends now.
Thanks dude. This **** needs publicized more. I went through a few links before I found this.
I would and tell people to use something non-metallic and removed the battery beforehand. I did just to be safe.
Hey guys, had my hero for about 6 months now, bought it from a friend was working properly. After playing around with rooting and flashing custom roms my USB has decided to not work anymore, I can still charge the phone which isn't so bad but can no longer mount to pc, can you guys think of any suggestions to what it might be?
Same here. No idea how to fix.

what rom are you using?
could be rom related
I've tried flashing different roms and it still seems the same, I'm using Tegro, but it worked fine when I first flashed the phone
have you been try this one try this one
connect your phone to the usb port of your pc.
while the phone is still connected, turn it off and turn it on (remember do not unplug the phone keep it connected to the pc).
as the phone is done with the booting process you will get what you wanted.
After a few weeks of putting up with my USB issue I have finally got it to work again. All I did was use a standard wall USB charger and a USB mini cable instead of using a Motorola charger. But so far after using it all day it has seemed to fix it

Last week when I plugged my USB cable into my phone, it acted normal. The screen where it asks me if I want to connect USB came up, and I said yes. Everything was normal. It was baller.
Today, that doesn't happen. The screen doesn't come up and all the USB cable does is charge my phone, much like the wall plug does.
I've tried to install USB drivers, but they always require me to find "Android" in Device Manager, and it's never in there. The USB cable is doing nothing but charging my phone.
I managed to add a few mp3s over wifi, just to make sure that was actually working.
The phone is not rooted, (I was actually just going to try to do that) and everything is stock aside from a few apps.
I would really like some insight on this, please.
Do I need to get the phone replaced? Am I doing something wrong?
OK, I new to this, but thought I'd comment. If USB debugging is turned on, my seems to do that.
Settings -> Applications -> Developement -> USB Debugging

I've done nothing to the phone. Only installed a few random apps.
sorry to hi-jack your thread!
mine does exactly the same, but all i've done is manually update to 2.3.4 and my usb hasn't worked since, like you i've tried installing the drivers and that's done nothing and its also in usb debugging.
i don't know what to do or how to get it to work again, all my searching on here and via Google don't bring up much

Put your phone into bootloader mode and try whether it detect or not?
And also, see if there is two line of words written
USB init start
USB init end ;-)

Try another usb cord, and especially if you're using the samsung cord.
I had the same issue but when I switched to my Htc cord and my blacbkberry cord, everything worked as it should.

Wow, you're right. My HTC cord worked. Thanks a lot.
I have had this happen on to me and have determined that a) the long cable that came with the NS4G is unreliable when used for USB connectivity with my PC. Shorter cables (even the shorter Samsung cable that came with my Epic) work consistently. I am guessing that this is a USB Bus power issue and some people will have better mileage than others using the stock cable, depending on their PC.
b) on a few occasions, it seems I've somehow borked the PC's USB controller and the PC wouldn't recongnize anything until I rebooted it.

I am getting the

when in bootloader and when doing the i press vol up and vol down (triangle with android in it" with downloading below).
I would like to flash my phone to factory using Samsung Simple downloader for NS4G.
Background, installed Ice Cream but didn't have radio.img so used an SU to downgrade back to 2.3, did that but no mobile network. Then the phone updated to 2.3.6 and now getting that error. Any help will be appreciated.
I searched a few times on this forum and on google.com no luck. tried to adding a recovery file manually and zip it as update.zip and install from bootloader no luck. (use file explorer and dropbox to get files on to phone).
Thanks

i had this issue a few months ago, turns out the usb port on the phone got defective so i could only charge it but not use the mass storage function, had to get it replaced under warranty! hope this isnt the issue with you guys

Was your phone rooted at any point before the issue? Not sure if they would fix it under warranty for me. I will call Samsung and see.
Thanks, I tried that but no luck. Still need to tried other cords. Also.
My phone developed this problem a couple days ago. I haven't done much to troubleshoot it...figured the port must be damaged.
(Not using the Samsung cable, btw)

It might be the port. I will have to get a samsung cable and try it, but i doubt it will help. Plus i can tell Samsung I tried everything. (I looked a ticket, but they said get a samsung cord, they don't trust the Palm Pre cord i am using).
I had to downgrade to the HTC Hero until i get the phone fixed.
First and foremost I already have the drivers installed properly on the computer the OEM cable and a few others to be sure it wasnt a cord or computer issue.. But when i plug the phone into the computer the nexus doesn't show up either as i mass storage device or even in device manager. To see where I'm coming from I bought the nexus online and the seller sold it for parts and said the phone was in alright condition and said that it works in excellent condition before he wiped the phone and that it had no OS and that he didnt know how to fix. So I thought it was just a simple fix and bought it. Lucky the phone came with twrp already so i plugged in the phone and nothing happened, and I tried sideload and also didnt work. like i said before i installed all the drivers and everything so thats not the problem. I tried the Nexus Root Toolkit and didnt work. I even did the OG way by manually using fastboot but the computer didnt detect the phone. The only method i have left to use is the OTG method so i wouldn't need the computer. Has anyone had this problem before? I searched everywhere to see if anyone had this problem but couldn't. But if you guys already made a thread for this specific problem shoe me. Im thinking its a hardware issue something to do with the port
That's a tough one hopefully it reads OTG and you can flash something. I would grab latest udated twrp and flash first in current recovery. A lot of the new stuff requires it.
this happened to me after owning my Nexus 6P for almost a year. When I plugged the phone into my computer's USB port. Windows didn't acknowledge it BUT the phone was charging.
turns out I needed to get my daughterboard/USB port changed. Sent it in to HUAWEI and they did it for free under warranty (I was without a phone for like 8 days).
I am actually starting to have this problem now... I am certain I am well out of warranty. Plus... I don't trust Huawei.
