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?
Hi,
I am a moderately experienced owner of S2 which has the following details
from *#1234#
PDA:I9100XWKF3
PHONE : I9100DDKE4
CSC: I9100ODDKF3
Country:India
from about phone(in settings)
Model # : GT - I9100
Android Version: 2.3.3
Baseband Version : I9100DDKE4

Build number : GINGERBREAD.XWKF3
I heard there was a KIES firmware update for my phone and so wanted to update. I installed KIES into my laptop and when I fired it up it notified of a KIES software update(update of KIES itself) and after updating KIES,I connected my phone which was detected properly.
I did the firmware update subsequently and after that the problem started. When I connect my phone using USB to the laptop, nothing happens, the phone doesnt charge even. Everything else works fine. I searched various forum posts but none of them work
1. Tick/Untick the USB debugging checkbox at Settings>Applications>Development - did not work
2. type *#7284#, toggle PDA <-> MODEM. didnt work
3. One curious thing is that, if I connect the phone after the phone is fully booted, it is not detected and the phone doesnt charge at all. But if connect the phone when it is switched OFF and then Switch it on, the phone does charge but still is not detected.
4. The cable is not faulty as it works perfectly with other samsung phones(Fit etc...).Also, its not the problem with my laptop as other mobiles are detected fine on my laptop.
pls help
Couple of things to try
1 Check the pins of the bottom of the phone?
2 Uninstall Kies and drivers, and reinstall?
The pins seems to be fine, anything specific I should look for?..and I have tried connecting in other systems with KIES and still the same problem. My friend's android phones connect fine in all the systems. Even if it was KIES drivers problems, shudnt it atleast charge the cell??
Rule one is use official Samsung USB cable
Rule two is use a mainboard USB Port .
jje
Hmm, It is a official samsung cable.
I did not understand what u meant by mainboard port?? I am not using any hub if that whats you meant. I am thinking it is an issue because of the firmware update.
I was actually thinking of getting the firmware update and subsequently, after backing up using clockworkmod, I was thinking if getting either villianROM or revolutionROM. Now, backing up is out of question as the present firmware is broken. So, If I go ahead with the flashing, what options do I have if I want it to get to factory state for warranty purposes.
Connecting the AC charger when phone is switched on, will initiate charging?

yes. Normal charging happens fine. So its not the pins I guess.

How about a factory reset? Try that!
sorry, should have mentioned that. I did factory reset twice and then went into recovery mode and did a wipe and clean and cleaned the cache too.
So, alternatively where can I get the stock rom/firmware for the specs i provided above. I found a thread where various firmware were provided but one compatible with my kernel..csc etc,, was not there
I appreciate u all replying. I tried on the indian thread but nobody seems to feel it worth replying.
Mainboard or motherboards USB port only .

Hi.
Doesn´t matter what pc i connect to but all are win8
usb debug is on, unknown sources is on, installed Samsung Galaxy S3 ToolKit v7 and Samsung_USB_Driver_1.5.16.0 on pc, Odin 3.07 does not see any connected device. phone makes the noise when connect to usb and charghing just no reaction from pc or any reaction from android os pulldown menu.
I installed that leaked 1.3gb arab official samsung rom since i wanted to use my allshare cast dongle, tho I seem to need to use triangle away in order to get a allshare cast connection with my tv, and to use triangle away i need super user acces for which i was going to use ODIN with CF-Auto-Root-m0-m0xx-gti9300.tar.md5
Has the USB port been pshysically damaged? i just did a factory reset, back to the default original leaked 4.2.1 which did nothing to solve my problem.

Go to pc system device manager, is the phone listed under connected usb devices or has a problem noted?
If it is there and shows the correct drivers then the problem is on the phone, I'd try going back to EMB5 stock first - rather than a leak.

okidoki, now i am confused! see screenshot.
what is EMB5? and if it's a rom can i still make it work with my current issue?
Do you have an entry for Samsung USB controller within the Universal Serial controllers, if not then the device isn't being recognised.
By EMB5 I meant flash the genuine stock Samsung 4.1.2 ROM via odin, not some leaked version of 4.2.
This will test if your issue is hardware or software related.
Finally, you are trying to connect the phone to odin in bootloader mode - right?

You mean power + volume down + home button? yes. tried it, used t recognize it that way.
Is there ANY way to root my device NOT using the usb port, I'm going to assume it's been damaged somehow (beer, maybe a smal shallow bath) It did act weird a short period afterwards with making the "connected and charging beep sound" and un-doing it, then re again but all that dissapeared pretty quickly, like the day after. Otherwise the phone is in pristine condition and not even a scratch on it despite heavy usage through usage since bought in July.
IF I send it in for service, do you have any good advice for me on how to approach them with my odds being the best, I mean, custom rom, but that should'nt matter when they test the port and notice it doesn't work for them either, right?
Jesus christ Maria, booze damages has cost me more than the actual alcohol and this is Sweden we're talking about, most expensive place on the planet.

Hi,
S2 suddenly stopped picking up USB. "USB Device Not Recognised".
I've checked all guides and i cant get it to work. Its not my USB ports my S4 works fine.
I have replaced USB pcb many months ago no problem until now, it charges fine makes standard noise when i plug it in.
I assumed it may be due to custom rom, i tried to flash stock in Odin download mode but it does not recognise any USB device.
I'm kind of stuck and don't know what to do next hope someone can help.
Update: I'm going to try Mobile Odin, see if flashing original Stock firmware fixes it.
You can try to reinstall samsung drivers (http://forum.xda-developers.com/showthread.php?t=961956), see if that fixes it.
It's unlikely that a custom rom is causing it, unless the problem happened as soon as you flashed it, rather than suddenly not working.
Thanks, tired it no luck, I may have to replace USB PCB. flashed stock firmware with mobileOdin I hoped it would fix it.
:good:
Thanks for that outstanding contribution to the thread
Hello Everyone
I am putting my problem in this general section with the hope to ask for help to more people compared to the Mate 8 section where not a lot of people go these days.
Since a while I am not able to connect my phone to a laptop. If I connect it to a laptop it just starts charging but nothing else. I have tried everything like:
Changing Cables (tried more than 5. I dont have the original anymore)
Changing Laptops
Changing the USB port of the phone itself
Updating Drivers
Installing Hisuite (current version 5.0.3.300)
Restore phone to factory settings
Complete formatting
Updating to the latest version (Current version Nxt-L29C185B582)
Changing the USB debugging/ Connection (MTP/PTP/etc)
And what not
The problem is, it doesnt get detected on the computer and cant connect to adb as well. All I want is to unlock bootloader and Install TWRP and Magisk. I have the unlock bootloader code but no way to unlock it since I cant connect.
Can anyone help me in fixing this stupid problem ? It is getting frustrating. If there is a hardware issue, what part needs to be replaced? Any help would be appreciated.

Go to the Settings of your phone---> About phone----> Build number tap this 7 to 8 times-----> Developers option is enabled----> back to settings ----> go to developers option ----> enable USB debugging.
When you connect to the phone to the laptop you will find an icon on top of the screen of your phone with a USB mark "like a trident", pull down the top menu and find the USB connection tab, (like changing the sim card if you intend to call through a specific card) e.g quoted, double tap the USB tab to obtain options ---> 3 options 1) MTP 2)PTP 3) USB charging only----> select the first option MTP (Media transfer protocol).
Now connect to the laptop you will find exclamation marks in the device manager of your laptop. Load the appropriate drivers on your computer and viola! this will establish connection with the device you are having. if you find difficulty in installing USB drivers, search the thread "Attempt to load USB drivers for Micromax E484 on win XP is a fiasco" in this forum. You will find the solution for USB drivers

Nope. Doesnt happen
When i connect with the laptop, my laptop doesnt even make that sound for the connection.
What is the model and OS version of the device and the model and OS version of the computer? According to your symptoms your phone appears to be in option 3) USB charging only. The phone will not be detected by your laptop or the like(Computer) in this mode. Merely remains in a charging state. Are you certain the option 1) is picked MTP? If the phone is not detected there appears to be some hardware failure, try another USB port to connect to the laptop. if all else fail a service technician will pinpoint the fault. It may perhaps be a data transmission failure of the devices port to the interior of the phone. This is merely an assumption.
best remedy would be a service technician.
Hope this helps

I have tried changing the usb charging only to all possible options but it still is the same. I tested in Linux and when I connect the phone nothing shows up in the logs. It's like it's not being connected . I have tried changing the usb port itself from the phone but it remained the same.. can the flex cable be a problem ? Mate series was never launched in India so I don't have any help from the service centre. I have to order the spare from eBay.com so there is no qualified technician who can help.. that's why I have to fix it myself somehow..
Thank you for your help

I quite doubt the cable will be the culprit as your device charges the battery while in an established connection with the laptop. As you state the phone USB port was replaced, it could be a some glitch before the USB port in the device where there is an interruption in the data transmission signal that cannot be detected by your laptop.
Could you boot your device, computer and connect the two and take a snapshot of your device (whilst connected to the laptop) and paste the same in the forum?
Perhaps visual cue could be better at dealing such mishaps.

Your USB trident icon is not indicated on the device, If you were to receive power from the laptop the trident would be displayed on top of the screen, even for charging the battery. The power source for your device appears to from other than the laptop.
I have pasted my device after connecting to the computer and the second icon from the top left is the USB Trident icon indicating connection with my laptop. Have taken the snapshot of the menu that I was describing .
I strongly feel you have a hardware failure rather than a simple fix and would require the help of a technician (ordinary if professional is unavailable). Am skeptic you could mend that on your own unless you are proficient in electronics. This mishap is not due to flashing wrongly too, unless you have changed the stock ROM with some custom ROM which has some bug that affect the USB alone.
Take the assistance of a technician whether professional or less is my counsel

I did flash a different rom .. but then back to stock recently.
I can do basic electronics but the if the problem lies in Mobo .. then nothing can be done .. as I don't have the spares available in India. But I would hate to lose this phone as it was a perfect fit for my needs

If you do not have spares is best left alone rather than tampering with it and rendering the device useless if any untoward incidents tends to occur.
But I would hate to lose this phone as it was a perfect fit for my needs
Send to the vendor directly if you have warranty for the device stating its complaints or request your relative or friends who live in the area where you bought your phone to hand it to the vendor or service technician and bear its expenses

Is there a way to unlock bootloader somehow without connecting to usb ? That would also solve the purpose.. I want to root it for some of the things to work and with the latest upgrade to latest version I lost the unlocked bootloader and root.. if somehow I can unlock and root .. I should be fine without the usb connection to computer.. but I have ran out of ways
Does Kingroot work for you?
I mean did u try it or u just want magisk?
If u didn't, kingroot may be able to root ur device and unlock ur bootloader, then u can flash TWRP using rasher.. & make a backup BTW...
After that, try using the adb sideload in TWRP to test ur connection with ur computer.
TWRP for ur device : (q.gs/DxuAH)
There is a way to unlock bootloader without USB via developers option.
Go to settings-----> About phone-----> Build number ( Tap this option around 7 or 8 times) till developers option is enabled------> go back to settings-----> developers option-----> OEM unlock option (Enable this option) to unlock the bootloader.

There is no FRP unlock, to circumvent FRP you need to factory reset or flash your firmware. The above quotation was to unlock the boot loader as you cannot access through your computer. Your sole option to unlock boot loader was through the above directions.
Moreover, King root application never ask for boot loader to be unlocked. Although a little unstable this is the initial program to root any device. Once you have the TWRP setup then you could switch to Super Su etc. according to your preference.
Could you paste your developers option snapshot here...
