Hi all,
All up until a few days ago, my computer/s cannot recognise my Samsung Galaxy S2. Whenever I connect my phone to my computer, the phone believes I am plugging in the charger.
I have attempted to turn on/off USB debugger, attempted the USB mass storage connection method and also attempted to use Winamp's automount option.
I thought it could have been my cable and I have tried different cables and phones and it seems my phone is the only problematic one.
Before this issue, usb used to connect very easily, even used for my car headunit.
Yesterday I was running the 2.3.6 firmware and recently changed to 4.0.3 and neither allow the usb to be working.
Has anyone encountered this problem and does anyone have a solution for this problem?

Did the USB work on previous firmware if so you have messed up the install revert to older stock rom firmware and test .

It didnt stop working due to a firmware upgrade. It randomly stopped working when I was using 2.3.6 so i thought maybe upgrading would do the trick, which it did not.
Try doing a factory reset..
Yeah, did a factory reset when I changed from 2.3.6 to 4.0.3 and just tried again. No difference.
I did notice that this error may have occurred when I may have dropped the phone. Not too sure how this would affect anything but just putting it out there.
Did you drop it with the usb connected?
Sounds like its a hardware problem, just try flashing stock again to be 100%

Dropped whilst drunk unconnected to anything, did have a case on it however.

ICS is not an upgrade its an unstable beta rom not passed by Samsung for use .
Possible dirty USB ports .

How would one proceed with cleaning the usb ports?
In the past I happened to have trouble connecting with the usb port and I solved unistalling and reinstalling Kies. Have you already tried?
I believe what I'm attempting to do is to even use the phone as a mass storage device. I used to be able to do this via straight windows to any computer and even my car headunit. However at the moment a cable is only recognised as a power source and not as a data connection.

just gave this a go, going to leave it overnight to dry. wish me luck
No luck but I have concluded that the USB port possibly could be broken. I'm wondering, does rooting the phone void warranty?
Unfortunatelly it does...
Wipe everything U can, flash back original firmware and do reset with factory JIG... Than U have chance to claim warranty. But its not 100%...
There is thred about reverting somewhere...

Try again but after restarting ur computer !
Does the computer see any external drives (whether you can connect to them or not)?
Does the computer make a noise when you connect or disconnect the phone?
My friend's got a Legend with a USB malfunction (which I'm supposed to repair ). I've gone through all the threads and posts, and I couldn't find anyone which had precisely my problem.
When the phone's switched on and connected to via a USB cable, it starts charging, and the pop-up to select Charging, Mount as disk drive, Sync etc comes up.
But on the computer, whether I try USB debugging, or Mount disk drive, or the others, it shows the error "USB Device not recognized". I've installed HTC Sync, and am able to connect other phones without any problem.
I tried connecting the USB in fastboot, but it doesn't detect it either (FASTBOOT doesn't change to FASTBOOT USB).
I just wanna confirm with experts if this' a problem with the hardware (Got a sample here :http://forum.xda-developers.com/showpost.php?p=18420923&postcount=11) before I go to the service center.
Thanks
U might be using the wrong data cable. There are 2 different types, there is the old type that only has 4 connectors in the mini USB plug (phone end), the new ones have 5 connectors.
Another possibility is that the cable is simply just damaged.
I had the exact same issue with an external HDD that worked, then stopped then worked again then stopped, tried a new cable and worked without issue.

I'm leaning less to the hardware side.
I have had this problem before (not entirely identical) and after fruitless attempts in fixing I decided to reflash my rom and USB worked again.

Thanks for the reply guys Had to replace the USB port connector PCB.
Just for the info, I was not able to re-flash the ROM since the phone was S-ON and bootloader locked and couldn't get FASTBOOT USB to work.
USB Version...
Hey guys, long time reader thought I'd contribute my frustration to hopefully help someone in a similar situation.
I spent a few days wondering why I couldn't get any of this to work no matter what cable I tried. For some reason, my HTC One X didn't like dealing with fastboot through my computer's USB 3.0 slot. When I finally tried a 2.0 slot on the same machine, everything went through just fine...
Cheers!

This threat will indeed do the trick and your USB connection will be back
Well, the day before it occurred to me that I'd like to install a custom ROM, therefore I went on to plug my phone into my PC and for my surprise, the phone didn't pop that MTP warning and the PC did not recognize it.
So I went around and changed USB ports, cables and PCs, same thing.
Decided to try Mass Storage mode, when I press the START button and put in the cable it goes back into the main start screen.
So I went on and tried that *#7284# trick people used since apparently 4.0.3 bugged some crap stuff in the phone, no success either.
Strangely enough I can connect the "pendrive dongle" and it will map pendrives.
Well, I don't have my phone rooted or with SU so that means CWM from app store won't be able to install the recovery module, and I can't install... you get the picture.
Nor ODIN nor HEIMDALL will recognize my phone in recovery mode, wich suggests that the data lanes on my phone went somewhat dead.
Finally, any cable I plug in the phone says it's charging my device, wich leads me to belive that the usb port is dead.
Anyone had this issue?
Anyone can confirm me I'll have to take it to Sammy's assistance?
Sure looks like the USB is dead/dying.
Sent from my digital submersible hovercraft.
So I got one more question, can I root and/or install CWM so I do not stay dependent of the USB to update it or I do need to plug in the USB to install CWM through ODIN?
Several problems
It can be several reasons
1.the usb is dead buy new
2. try factory resetting the device
3. install kies on pc it will install all the drivers that you need
4.your usb port(of the phone) is dead
I had the same problem pc was saying "USB cannot be recognized" I TRIED EVERYTHING from factory resetting, changing pc usb ports, changing usb, changing kernel, roms, trying on other pc, reinstalling kies and drivers but nothing. The problem was in the usb port on the phone where you connect the charger on the phone. That part is weak and so you have to change it. Take to customer service with your warranty and they will fix it without charging anything just tell them your problem and say that you read that most of the galaxy s2 users have this problem and that you didn't touch the hardware of the phone

Warranty has already expired.
Kies was installed on the PC, ODIN gives no info @ COM port.
I wanted to connect it just to root and install CWM so I can swap ROMs as much as I want.
Thing is, the customer service wants 1 week to assess the issue and probably 100USD to fix it.
So for some god-knows-why reason my phone decided to conect to MTP while charging, I quickly restarted it into revocery mode and flashed CF_Root w/ CWM5.5.
Successful!
Bloody USB thingy!
Now I can start messing around with the phone.
Anyone has a n00blet guide on ROMs?
I was thinking about moving to CM 10.1, one of those nightlies running 4.2.2.
This is the one I used >> CF-Root-SGS2_XW_OXX_LPE-v5.5-CWM5
Can anyone suggest actions?
For future you should change your USB-Port. Here we get one for about 15 € (about 20 $) in ebay. It's very simple to change and then you have a full working phone again. Just watch the Videos on Youtube and everyone can do this. Hope I could help!
Hello Everyone,
I was worndring if it is in some how possible to upgrade my GT-I9070 from gingerbread 2.3.6 to Kitkat or other custumized rom without having to use odin.
I have a problem with connecting my phone to the my pc, my laptop won't regonize it, I think is a hardware problem.
Thanks a lot

Not unless you are already rooted. Does the PC not recognize that you have plugged it in at all or does it just not load the drivers correctly? Best way to tell is to open your Device Manager and plug in the phone. the DM should reload and show something, whether an error or not. If it does not blink out and reload when you plug / unplug the phone, then it's either a hardware issue with the phone's USB port, a bad cable, or bad USB port on PC. And it is possible for a phone to charge correctly, but have issues connecting to a computer if the data pins are messed up. If it IS the phone's port, the repair isn't that bad and could be handle with some patience and simple tools as this one does not involve soldering. You'd need this:

Dude really thankful,
As you say, the PC dosn't recognize that the phone is plugged at all, I try all the usb port on my laptop, different cable, and even different laptop and the same problem keep comming up.
I tried also to reboot in odin mode to see if my laptop detecet anything, but nada, nothing in the DM.
Also, like you expect, it can charge but no data connection, and whene it turned off and I plug it it automaticly turned on by itself.
I pretty convinced that it usb port is screwed.
So, to install a rom my phone have to be rooted!! no way to root it from the recovery mode?!
Thanks again

You can try to clean your USB port of the phone with some compressed air, in case some pocket lint got in there too. Doesn't take much to mess these things up, unfortunately. But yea, I doubt there is a way to root it in the stock recovery as most Samsung phones don't have this option. It'd take less time to just fix it probably then figuring out how to jump through all the other hoops to find a way around it.
Hello people,
i got a small problem. I just bought a sm-g925F and be very happy with it so far. Well the problem is, that i can't connect to the phone via USB to flash another FW because 6.0 isnt aviable for switzerland (AUT) now. For those who think they maybe got a solution: impossible. I already tried everything in every forum. I tried different cables, different PCs, download mode, usb debugging, different drivers, manual set drivers, exit silent mode, wipe device, apply a new usb port on the device (im not that shure if they really did it).
Win 10 gave me a message, that its unable to get informations about the connected hardware. For me there are two solutions: 1. Hardware device of the device core PCB, 2. the Firmware is broken somehow.
ANYWAY i dont want a solution for that. Im just ask if its possible to flash another firmware for example via Wireless Lan oder an SD Card, connected to the S6 via USB adapter.
I am thankful for every reply
Kind regards
Same problem here, USB was working 100% then I got the 6.0.1 beta and now I can't get USB at all.. Are you on the beta?

Nope, i did a usual update to 5.1.1 when i got my phone.
if the device is still working...dial *#0808# and select MTP+ADB and try if u can flash the new FW you want to flash.
Mtp+adb was already selected
May i change these settings?
Get usb otg cable, and push firmware as adb or put zip rom on usb and browse the connected usb via otg in twrp

Hey guys i just got my S6 back!
I gave it to a samsung partner after some phones with the samsung service. They wasnt able to fix this problem. So i decided to give it away to repair it. It took 6 days(!!) whats amazingly fast and they installed a new main pcb, usb slot and another thing (dont know the part name) and it works fine now!
Thanks for all your help.
