Hello,
Please help me. My phone will not connect via USB to a PC. Steps I have taken to try and solve this so far:
- Tried 3 different USB cables;
- Re-installed Kies, Samsung USB drivers, Android SDK google USB drivers, etc
- Turned USB debugging on/off
- Turned Allow Mock Locations on/off
- Tried USB Utilities, tapped apps, etc.
- Tried *#7284# dialpad trick
- Tried 3 different computers (all running win 7 64 bit)
- Unmounted/remounted USB in CWM recovery
- Flashed 3 different ROMs (jedi mind tricks, clones n drones, darkside evolution)
- Restored a nandroid backup from when it was working;
- wiped cache, dalvic cache, factory reset, etc.
When i try to mount usb in CWM it says "E: Unable to write to ums lunfile (No such file or directory). Yesterday it was not charging over USB, now it is (flashed darkside evolution ROM this morning).
Current setup:
Android: 4.0.3
Baseband: T989UVLE1
Kernel: 3.0.8_SGH-T989_DARKSIDE.VENOM_02+
Build: DARKSIDE.EVOLUTION.3 v7
If anyone has any ideas I would really really appreciated hearing them. I have been searching and trying fixes for the last couple days and i'm about ready to throw my phone off a bridge.
Thank you!
USB port is shot. This is a know problem with this device. The device will be able to charge, but will not be recognized by the PC. Had the same issue with my wifes phone and was unable to root. Half the time, it wouldn't even charge using the car charger (though the wall charger always worked).
Called TMO and received a warranty replacement. They charged $20, which they later removed when I called and asked them to.
Thank you, at least i'm not crazy!

Yeah for some reason. It looks like a batch of phones have a usb port problem. I assume the phone is newer than February? Because it seems there are a lot of this problem including the power button surfacing on the forums as of late

It is an older phone, purchased last fall right when it hit the shelves. I actually took the thing apart last night and noticed that there was some water damage, it spent an evening outside earlier this year but I hadn't noticed any issues until this weekend. I cleaned some corrosion out of the USB port out with an old toothbrush and bolted it back together, fired it up and everything seems to be working again. Wonder how long its gonna last?

Hello!
First things first: i already googled and search-functioned about 8 hours for solutions, tried them all and still got no luck so basically you girls and guys are my last hope. i hope my english isnt as rusty as i think it is. if i make any mistakes of any kind, please bear with them.
Used Hardware: Galaxy Nexus, the original Samsung OTG cable and the original Samsung charger
Software: Rooted, Bootloader-unlocked, stock-Android 4.0.4, 4.1.1 and 4.1.2
What is my problem?
as soon as i plug in the original charger it charges (duh!)
however, the moment i unplug it, the phone keeps thinking it is being charged. forever!
plugging in a original samsung USB cable without connecting it to something doesnt help, it still thinks of being charged.
but plugging in the original OTG cable stops the phone from thinking of being charged! (i dislike the thought of running around with a OTG dangling around the phone so that isnt a solution to me )
what happened before that incident?
bought on 15th December 2011
last software update 4.1.1 to 4.1.2 on 16.10.2012
worked perfectly until Yesterday
Recently i played around with the OTG cable and tried the following hardware to see wich works with my setup:
external HDD - NTFS formattet
PS3 Sixaxis controller
Corsair Flash Voyager USB3.0 Stick
AKAI MPK mini USB MIDI controller
Newest apps installed:
Sixaxis Compatibility Checker (18.10.2012 installed, used for half an hour and deinstalled)
Wolfram Alpha (17.10.2012 installed)
MyBoy (an GBA emulator - 12.9.2012 installed)
-latest ROM for that emulator downloaded on 13.9.2012
what did i try to fix the problem (in exact order)?
rebooting
changing the battery from 2000mAh (its an original, bought about half a year ago) to stock 1750mAh
removing the battery for 10 minutes
draining the battery to absolute zero and fully recharge it
carefully cleaning the microUSB port (with battery remover of course)
super carefully bending up the thounge-like part inside the microUSB port so that it doesnt get in contact with any surrounding metal parts (battery removed of course. when i say super carefully, i mean super duper carefully! i know how fragile those parts are!)
trying to hard reset the phone (that was a failure i just got from fastboot mode to a droid with a red triangle and an exclamation mark on its open stomach)
factory resetting the 4.1.2 via factory reset option (backup with Titanium Backup was made correctly but i forgot to copy it from droid to PC :silly: )
wiping the cache via fastboot
quick reflashing the 4.1.2 via fastboot
quick downgrading back from 4.1.2 to 4.1.1
quick downgrading back from 4.1.1 to 4.0.4
quick upgrading to 4.1.1 (it still is in that state)
complete reflashing the 4.1.1
- with reflashing bootloader
- with reflashing radio
- with reflashing recovery partition
now i am out of ideas
i think the USB port is seriously damaged. but since i am not so good with soldering and electronics i fear that i am not able to exchange that.
any more suggestions or ideas what might have been the cause?
next few days i will take it to the service center wich i really dislike to do because here where i live that means they keep it for about 6-9 weeks to fix it and i will not get a replacement in the meantime. anyhow my hopes are low that they might fix it i rather believe they replace it for a new one wich i also would dislike. Good thing i made a insurance for that device so in worst case i dont have to pay a single buck...
greetings everyone
Weird. Did you try flashing a stock Google 4.1.2 image? (Check out mskip's thread in Galaxy Nexus Android Development and download the toolkit - make sure it's compatible with 4.1.2 first)
Yes your USB port is most likely broken. Many others have had this problem including me.
Mine was so bad that my PC wouldn't recognize it and neither of my pogo pin docks would work.
I replaced the USB flex cable this week and it works great now. It was a relatively easy repair if you take your time and have the right tools.
The part only cost me $7. http://www.ebay.com/itm/190704059979

The USB ports should be the same as micro sd is a universal standard I believe.

I had that same issue after my phone got wet. After about 2 weeks the issues with my USB port went away altogether.
You take your phone places where water might condense on/in it?
thanks miketoasty and thanks El Daddy! i really like this forum a lot very helpful people here.
i ordered the part. Estimatet shipping date somewhat between 30. october and 5. november.
will post updates
at least that error of mine doesnt drain extra battery
reuthermonkey:
i cant think of any place i visit frequently with high levels of moisture or with wet places. I am really careful about that because i love my Nexus witch even goes as far as never ever taking it into the bathroom (not even to a save and dry spot) while showering or bathing. Rain is a bit rare here and even if it is raining i wont leave the house without putting the phone inside a phone-pocket and into the inner side of my jacket.
greetings
I had the same issue as you. I ordered a new charging port cable for $7 on ebay, installed it in 15 minutes, and all is well in the world.

If anyone else is having issues, I have a spare USB flex cable that I can send you for just the price of shipping...most likely $3 or so.
For the past few days i have been racking my brain trying to figure out what went wrong.
For some reason I can no longer connect my phone to my computer to transfer/move files. it acts as if the drivers will not take. when i check the device manager it reads SAMSUNG_Android with the yellow !
I have reinstalled lastest drivers from Samsung site, removed all drivers and tried from Kies software/ rebooted pc and phone countless times. tired my laptop where it use to always work and same results. One this i did notice was at some point i got an error on my internal sd card and that i should format it. I backed up all files via ftp formated the internal sd and tried again.. all with the same results. I have also tried 3 different cables.
PCs both windows 7 one 32bit the other 64.
Phone e4gt rooted FI27, everything else stock
All and Any Help greatly Appreciated.
Here it comes!!
I'm hoping that I'm wrong BUT, that is exactly how my EMMC brick started. Let us know if your phone just shuts down and the only thing you will get is a blue light. There us nothing you can do then but take it back to Sprint for a free replacement. I couldn't figure my USB issues out for maybe a week and then it just died when i plugged it in to transfer photos I'd just taken 30 seconds before it died. Lets hope I'm wrong but I'm writing this with my new phone ate the exact same symptoms with my previous Sammy. Try to get your internal memory backed up now! Boot your CWM and mount your external USB. I wished I'd have.
Try a brand new cable and see if that helps. This phone seems to be especially intolerant of if connections.

Not sure what you mean by boot my CWM. External memrory is ok I can just pull that out. the internal I backed up with FTP was a pain but i did it. I hope you are wrong about the phone dying out on me I am sure they will give me a referb if that is the case.

I still say try a brand new cable. When I first had this issue I tried 3 or 4 old ones before buying a new one.
Today my brothers nexus s wouldn't charge except with one particular cable. I think that the cable and port are still within individual tolerances but together there is just too much play in the connection.

took your advice and tried a brand new cable. I am stil having the same issue. anything else i can try? I tried with both usb debugging on and off still same issue
Damn, I was sure that'd work. I guess if you were able to back it up it's time for a replacement.

Hi, I am having a slight problem and am at a loss.
First of all, my phone is stock. I bought my OTG cable a few months ago and it worked just fine. I was using it to play games with my PS3 remote. However, with less time on my hands, I put the games aside and with it, I was no longer using my OTG cable.
Whenever I plug in the OTG cable, nothing happens and I don't get a notification that a USB device is connected. I have confirmed that it is not the OTG cable as I have tried it on 3 other phones, all of which responded to the cable connecting.
I am not sure when this problem started happening, but I didn't notice until yesterday when I was trying to use my OTG cable. In addition, when I plug in my phone to my laptop, my phone doesn't give me the option to turn on debugging mode. Again, I don't know when this problem actually began. I mention this because I am not sure if it is relevant to my OTG cable problem. Yes, I have checked and debugging mode is enabled.
I am not sure what to do and I have scoured the web trying to find a solution. Maybe I am searching in the wrong places, or maybe I am not just searching correctly, but I figured that my last option was coming here.
I thank you ahead for your time and hope that a solution can be found. I will be more than happy to provide any more details of needed.

Sounds like a bad USB port. You can replace it yourself, or do a warranty exchange. I don't think it's software related but try factory resetting. Or another ROM.
Sent from my SAMSUNG-SGH-T989 using Tapatalk 2
It sounds similar to what my phone was doing a few days ago. I don't have the OTG, but when I plugged my phone in to the computer, it only went to charge mode and didn't give the USB options, and the computer didn't recognize it at all. I ended up flashing back to stock rooted and it started working again. I flashed CM and then AeonFluxx again and it continued working, so I assume that it was either an app I had installed or something extra I had flashed. Either way, it's working now.
TL;DR Try reflashing before you start tinkering with the hardware, that fixed a similar problem for me.

Alright, thanks guys.
I think I am just going to do a factory reset.
I am able to charge my phone just fine and it connects to the computer just fine as well (Heck, I can do what many others can't....connect to Kies). I have no problems with data transfers either.
So I assume this is a software based problem.
...I may as well root while I am at it....
Haha, I will tinker around a little bit more before I do a factory reset and come back with my results.
Thanks again!
Are you using a kernel with fast charge?
Never mind. You are not rooted so that is not the issue.
Well, it looks like the factory restore didn't solve either issue. So I ended up calling it in and hopefully the replacement phone will work. Gonna have to wait a bit though...GS3's are currently on back order.
Thanks again for the advice though guys! Appreciate it!

Hello Everyone, I'm using Galaxy Nexus GSM Version and I was using Purity Rom for a while, yesterday everything was working fine but today there occurred a problem.
1. I Can't connect my phone to my PC via usb.
It just charges it and Windows (windows xp) says it can't recognize the device. Then the screen starts flickering when i connect it.
I tried many different ports and wires, nothing happened.
2. While using my charger, it charges my phone only when its switched off, doesn't charge when the phone is booted up.
This whole problem occurred twice many many weeks ago and got solved automatically, this time its not helping.
So I wanted to ask you experts what to do? This time it's taking too long, i flashed AK Kernel too, flashed PA (these things were luckily there in my sd card)
I can't use net too due some network failure here, please help me.
Thanks a lot in Advance.

it might be dust or not.
if not, Look inside the USB port and you will see a "tab" there. Lever this up gently (after removing the battery) towards the centre of the port.

I did that and it worked! I gently scrated the pins of the battery and the corners of the usb pins. Currently its showing connection icons but can't access the files via PC, but still, its charging from every port plus my charger is working!

Hi, all...
Quick question: did somebody in this forum ever had problems with USB? Mine seems to work only for charging. 'Till the last week, it worked as MSC, with no major problems, then it became faulty, disconnecting and connecting.
Now, to have data connection, is necessary to put pressure at the male connector and hold it this way. I think that it'll require a new PCB, as it doesn't look like software failure. I've googled up and there were other people having trouble with Xperia, but not M, specifically.
So, must I bring it to the assistence?
There's only one way to find out where the source of the problem is: to reflash the ROM.
The USB connector might have got damaged somehow. You can try it with any other device or maybe another xperia m to check for software fault or damage of the USB connector. Try to keep your device at a level below the port for USB in your computer.

Tried with CM 4.4 (FXP one, that's, by the way, terrifc). But it presented the same failure, then I reverted to the stock 4.3's CWM backup, because I didn't want to reinstall every app. Well, at least I,'m now sure that's a hardware failure.

Tried everything (or near everything). It charges, however. There are a little failure, but it should work if the phone is left quiet or not shaken while using it connected to the outlet.
So, for now, I'm going to transfer things using Samba or detached SD (the last being the fastest). Later I'll send it for repair... Shame it perhaps won't work with OTG (a feature I've been searching for, when I bought XM), but, when having money, I'm going to get it fixed.
Thanks for the replies, anyway.

Most problems don't get fixed just by restoring /system. You have to flash the whole
ROM, if it failed with system. If you're worried so much about your data, then just backup /data then restore it afterwards...
I also have this problem.i just elevates the charger cable and its charging but its not working if its not elevated.tried different charger but the problem still persist.so i conclude that its the port in the phone that s malfunctioning.
