Hi guys,
So it looks like my USB socket is on the way out. It'll charge the phone fine when its connected to any mains power adaptor, but wont charge at all when connected to PC, nor will it appear as a device on the PC. I've tried several known to be working USB leads, and a couple of PC's but its no-go on any of them.
Before I go ahead and take it in to be repaired, is there any chance it might be a software problem, seeing as its still charging fine from a main lead?
How would I go about backing up my stuff (given that I cant plug it into a PC) and my data (have contacts synced with Google, not sure if there's anything else that I might want to save) and completely resetting the phone to a stock state? I may as well give it a go, and see if that fixes it before sending it for repairs, yes?
Is there any need to backup my apps in Titanium Backup before it is fully reset, given that I can just download them from Google Market again?
Its my first Android phone so I'm not entirely certain of the process involved. If it makes any difference, the phone is rooted, and using XWKL1 "Frankenstein" from the Intratech thread.
Thanks for any help you can provide.

PCs will turn off USB powering on excess current. An external power adapter however is identified as such since it has a short between the USB data lines D+ and D-. These two data lines are not shorted on a PC (of course ) as they are required for data transfer.
It is not absolutely necessary to backup Apps but you should definitely backup App data! This is best done with Titanium Backup backing up to your external SD card.
One more tip: before taking the phone to be repaired, make sure you reinstall a stock ROM and reset the custom ROM counter by using a USB Jig.
I was recommended one hack - doesn't seem to have worked for the majority from what I've seen, but it's worth a try - you've nothing to lose.
Post #5 here.
did u try connecting the phone as mass storage and see if it shows up on the pc? You can go to mass storage mode by going to settings --> Wireless and network --> usb utilities --> connect storage to pc. You need to click that and then connect the usb cable. Also after connecting it check in device manager if the phone is showing up in usb.
Seems as though the s2 has a really bad USB connector as mine has stopped working other than charging via Mains and more and more people are having the same issue. Samsung should really address this.

Also good to try is uninstalling KIES (make sure the drivers are uninstalled too) and then reinstalling. Plug your phone in AFTER the installation. If it still doesn't work, there is an option in kies somewhere to install the drivers again.
Hope this helps

Today i plugged my phone to the usb cable and instead of getting the usual connection option screen... nothing... The phone charges but no Data transfer. Did hard reset, still nothing.. now im stuck with the old firmware... any help plz?
might be the cable that you're using. i used before a cable that is not the original and the same thing happened to me, i.e. pc cannot recognize device.
Try Settings-->Other-->USB To Pc-->UNCHECK (enable faster data sync) this should help...
cable : original came with the phone (used to work up until b4 yesterday) also tried another micro usb cable that came with me N900 but still nothing.
I did the un-check "enable faster sync" still nothing
Did soft reset, hard reset using volume keys, and factory reset from phone setting itself. still nothing.. the phone charges.. but no data transfer.. its something to do with the phone because i tried multiple PC's the phone doesn't bring up the connection type option page

No harm in checking.Infact i faced similar issue once and the USB2 was disabled.It took me an entire week to diagnose the problem.These PCs have got a mind of their own and do mischievous things on their own without our knowledge.
But since its not working on multiple PCs,i am not sure.We'll hav 2 wait 4 a solution i guess...
hmmmm.. would a full system format and re-install be possible? and would it fix it? (talking bout on the phone)
HELP, HELP
SAME PROBLEM WITH HTC2 T0MOBILE
even on the boot loader screen, it charges but no USB stuck on serial.
even when on sleep mode and plug the cable orange led is on but it didn't wake up for choose (active syn or stoeag memory)
PLEASE HELP
i can do nothing, HSPL or rom upgrade
the cable and the USB drivers are tested more than 100 times
Most horror problems I had with the USB sync have been down to not having the latest version fo Activesync from microsoft. Uninstall the old version thwen reboot - now download the 4.5 version which I think is the newest and last version they made (unless im out of date) and then reboot the machine, then connect up the phone - but not immediately after the machine has booted wait a couple on mins, Windows takes longer than it often appears to be ready to go. One your hard drive led flashing light has settled down it is probably time to try. Then see if it finds all the devices in your phone.
If it doesnt go into the control panel and double click system, hardware tab, then select device manager and see if there are any devices with a yellow sign with a "!" in them. If there are delete them and then unplug the phone and plug it back in again. It might get past some stuck things. If it doesnt see anything new on device manager theres a menu at the top and look for "scan for hardware changes" this gives teh device manager another look at what its got connected.
If that fails open up the USB section under in device manager - its got a little plus next to it, press that plus and it open up all the names of chips you have for your USB control on the pc's motherboard. Write down the numbers and go and get the correct up to date drivers for that type of USB and install them. Then try the process again. Sometimes deleting the USB drivers and just doing a "scan for hardware changes" again, will reset the USB drivers and start things working, however it can get tricky if your using USB mouse and Keyboard to select anything if you delete the USB, because thats what the KM/mouse relies on to control teh machine, so have a PS2 mouse plugged in if you can. If that fails I would suggest reinstalling windows as its probably knackered. It amazing how things start to work wonderfully on a fresh copy of windows.
I have been where you are! And tried every suggestion that was given here. It all came down to the cord. I actually went through 3 different cords before I found one that worked and found that by accident. I bought an external drive and that cord works. For whatever reason, that is the only cord that now works for me. I only use it for data transfers. i use the other cords for charging.
Samsung fascinate
rooted
windows 7 with Samsung 64 bit drivers installed
back to stock DL01 and then OTA DL09 about five times today.
Here is the problem, when i mount my phone, intermittantly Windows 7 doesnt give me the pop up window that lets me view my sd card files. It gives me a pop up window with 2 choices:
Option # 1. View your files - this really doesnt let me view anything except 4 files one of them being a " Bootloader file "
Option # 2. Install Bootstrap Loader exe.
I have had my phone since september and rooted, rom"ed OTA"ed all of it and today this started happening.
When i look in Drives and Printers my phone is listed as a CD Drive and not a Mass Storage Drive.
Just curious if any one else has had this issue and what might have caused it to start happening.
I installed Samsung Kies earlier this afternoon but uninstalled it since it was pretty much worthless to fascinate owners and the U.S. isnt supported.
Any input would be appreciated. Thanks in advanced for any info.
have you tried re downloading the drivers from samsung.com? it worked for me.
This has been talked about in several places already. It is a common bug with DL09. The best solution is to flash one of adrynalyne's 1/18 test kernels found here. I hope this helps!
BTW: make sure it is one of the kernels with the cd fix
when im on 2.1 aosp, i have that same issue, to fix reboot with debugging enabled
Seems to be related to some new 'Media sync' option.
I did some playing around and the following seemed to let me 'mount'
the phones as before. ( But I dont like it. )
Hoping for some direction from Verizon tech on
a) what is media sync ?
b) how do I turn off permanently If I dont need or want to use it?
Unplug phone from usb cable.
Then on Phone... Menu...Settings..USB settings
Change to ' Ask on connection'.
then press home button.
Plug in USB cable.
When prompted...Press 'Mass storage'.
Now wait...wait..wait. Took about 30 to 45 seconds.
Annunciator bar should have usb symbol. Drag it open.
Press usb connected....Press Mount..
My laptop now recognized the SD card on E drive.
Copy files as usual.
When done...Open Anunciator bar and 'Turn Off' USB storage.
Media Sync is a mode that allows programs such as Windows Media Player and Rhapsody to access your SD card and copy over DRM protected music.

Thanks for this, it worked
not sure if it helps with the problems with 2.2 but whenever i had this issue on 2.1 this is what i did, turn off your phone with the usb cable in and turn it back on with the phone still plugged in. It always seemed to work for me
From your homescreen when you hit menu go to usb settings then make sure the little radio button for mass storage device is selected. That was my problem after the latest OTA from verizon. Also it takes like 15 seconds for it to all sync up.
i have searched these forums hi and low, googled, etc. still cant find an answer....
on djo5,dl09 i was able to plug my phone into the usb port in my car, then mount my sd card, and it would automatically connect and find my music and start playing it.
on either dl30, or eb01, i cannot get it to work.
it is very frustrating. everytime i try, (all different combinations debugging on/off mass storage/ ask on connect, etc.)
i get a "device connect failed" message.
does anyone else have this issue?
has anyone been able to get this to work?
Another fix when it shows up as a CD-ROM drive is to right click and eject. Seems to work every time for me.

Thanks your idea of reboot while still plugged in saved me. Tried every other idea with no cure.
Thanks for the post.
Just installed Superclean 2.6 and had issues. I tried ejecting the CD Rom device in Windows, but that didn't work. I changed the usb settings from Mass Storage to Ask On Connection and then tried it again. This time I received the Android guy asking to mount the drive. Yay! It worked! It does however show both a CD rom drive and the mass storage drive in Windows XP.
On another note, I found that if I plug in my phone without unlocking the password first it locks up the phone until I unplug the usb cable attached to the pc.
Make sure you are using a USB cable that has a good connection (like the original one). I bought some aftermarket cables, and while they are good enough for charging, I really think they fit too loose to keep a secure connection.

Thanks guys, this combination worked perfectly for me.
Just fyi, this is due to Verizon bloatware that has been inserted I to the kernel. Adrynalyne and company managed to flush it out of the Eclair kernel, but since we don't have kernel source code for the Froyo kernel yet, there's nothing that can be done at this time. When source is available, this will be fixed by our devs.

Hi mates,
since this evening, my Galaxy S2 (unbranded, unrooted, with stock firmware) was connecting fine with my PC in the "kies mode". I could use kies flawlessy, and I could regularly see my phone in my windows 7 (x86) explorer, and use explorer to read and write files from and to its memory.
Then, this evening, I got a notification, from kies, that an update (of kies) was available (2.0.2.11071.182.2), and I gave my consent to the updater. It did all its dirty job but after the installation of the new version, despite the phone connects via USB, every time I try to access the phone's memory from the PC, the connection drops. It restores backafer one second or two, but then again, if I try to access the phone's memory, it drops agains. The problem appears indifferently when accessing phone's memory from kies, and when doing it from windows' explorer, and this makes me suspect of the drivers, that the new version of kies brought along.
The phone connects correctly to the PC in the direct USB mode, and I can access its memory with no problem, and this also suggests that the problem should be the drivers.
So I uninstalled everything (new kies and drivers), and rebooted the PC, then I dowloaded what I believe is the previous version of kies: 2.0.1.11053.99.3, and launched its installation. After the end of the process, I rebooted the PC, just to be safe. According to the list of the installed software in my PC (in "Control Panel > Uninstall a program"), the drivers have rolled back, as expected, to version 1.3.2410.0 (before they were 1.4.something).
At the first connection of the phone to the PC after the reboot, I got notification from windows that the device installed correctly and it is ready to use (all the tree drivers are indeed reported as installed correctly)...
The point is that all this did not solve the problem at all, and USB connection still behaves exactly as badly as before.
I tried again uninstalling and reinstalling everything, also adding a manual clean up of the windows' registry from any entry related to "samsung", checking that the phone was not set in "USB debugging" mode, and disabling the antivirus, but despite everything appears to be fine, the phone regularly keeps on refusing to maintain USB connection alive everytime I try to access its memory.
What drives me mad is the fact that until this evening, everything was working flawlessly!
What else can I try????
I've just made a test on another PC running windows XP, with latest Kies 2.0.2.11071_128 installed. It's my office PC, and although I'm not 100% sure, I seem to remember that, until yesterday, my phone was connecting fine with it, and with that version of kies. But now, all of a sudden, I have the same problem also with this PC...
So, likely, it is a problem of the phone... the MTP application restarts everytime I try to access the phone from the PC, so... what can I try on the phone, to see if I can fix this annoying issue? I DON'T WANT TO FACTORY RESET MY PHONE, PLEASE!!!!
If any of you has any suggestion, I would be more than grateful...

I had the same problem the other day and I could not find a way to fix it, in the end I did a factory reset from Settings/Privacy and its ok now, just wiping cache did not fix it, factory reset was needed.
Dear Odia, thank you very much for replying and giving me a clue.
So... it appears that there's nothing else to do, is there? Buhahhaa!!! I want to cry!!!! I haven't made a backup and resetting the phone will be really painful... I'm already starting to feel the pain in my ass!!!
By chance, do you happen to know if I will have to buy again the apps I have already bought from the market? I have always kept both "Backup personal data" and "Automatic restore" ticked in "Settings>Privacy"... Could this be of any help?

You can always make a backup now before the reset and you will not have to buy paid apps again.
Yes but how can I backup my phone if kies will loose the connection with the phone as soon as it tries to access its memory?
Oh wait a moment, Perhaps I could use Kies air? Deos it allow to backup the phone? 'cause I can't test it now in my office, there's no wifi here...
From what I can tell, its the amount of the power that is supplied to the USB port itself that is the issue. I have the same problem when I put my i9100 on certain computers. Same thing happens to my WD MyPassport. Certain computers it works fine, and some it will power it for a bit, but once the device starts to draw too much current, it just disconnects.
This is why I try to do all my modding and flashing on a laptop, since, for me, they seem to be the most reliable in keeping devices powered up properly.
This is certainly a good point, but in my particular case, USB connection used to work up until yesterday with all the PCs I have (2 laptops and a desktop PC), whereas since yesterday, it works with none (with and without using the same USB ports). In addition if I use straight USB connection (hence not through the MTP app used by kies), it works fine.
Anyway what you have just mentioned is actually what scares me, because it would mean a hardware fault. But I'm crossing my fingers, hopefully it's (just) a software related issue and a factory reset will solve it. After all, straight connection works, so it would be really surprising if it were a hardware fault.
I will try resetting everything when I get home. Another "nice" busy evening to account to Samsung!
I guess if all samsung customers were honestly paid for every hour spent mending/fixing the issues of samsung products, the company would declare bankrupt in a matter of a few days!
Ok, I solved the issue with a drastic factory reset.
Thanks Odia for helping.
I spent 8 hours backing up and restoring everything included all the settings and personalisations. I went to bed at 3 am, eating only a quick sandwich in front of the bloody phone.
THANK YOU SAMSUNG, I wish to electrocute all your ****ing managers.
I hate when something in a device screws up all of a sudden and noboby knows why. It could happen again any time, and again I would have to spend hours mending a stupid phone instead of enjoying my life.
By the way, does anybody knows exactly what data is automatically backed up and restored on google servers by these functions?
"Settings>Privacy>Backup of personal data"
"Settings>Privacy>Automatic restore"
I always had both tiched, and I noticed that almost all the applications downloaded from the market that were installed on the phone, were automatically re-downloaded and restored on the phone at first boot after reset, but I'm not too shure I have understood what else was automatically restored.
I just read this thread for the first time, and was sympathetic to your issue when I started reading. I could see that there had been problems, but suggestions had been made and you seemed to be making good progress.
I was getting ready for offering advice and wishing you well with your problem.
Then suddenly you start to wish physical harm on Samsung employees.
Bye.

This is a simple solution try it and it will work for you the next time you face it most of the time it is a hardware issue i have been facing the same issue and nothing helped neither the factory reset nor the *#7284# procedure.
Take a pointy object like a pin or a paper and then clean your usb slot of the phone properly cuz most of the times usb pin points gets connected with each other due to the atmosphere and metal reaction. After that it will work like a charm for you. Before commenting anything negative i would appreciate if those who are facing this issue for a long time try this and then comment
Had the same problem, solved it by upgrading the phone software.
Setting > About Phone > Software update.
No need to afraid losing files. Hope that helps.
i faced the same problem on the GalaxyS sometime back. i did factory reset too. I got the same problem again. but i remembered it working on my LG TV so i did not go for factory reset. I went for re-install of samsung's USB driver for Windows. now it is working fine.
I fully agree that Samsung needs to be more responsible and responsive in resolving the such problems without causing data losses.

You could have saved a lot of hassle by installing a custom Rom and Kernel. I hate MTP mode! Mass storage mode is much better, I never had any problems with that....
Workaround - Power Management
This may be fixed, for now. However, in the future, there is a small workaround that you can use so that you're not required to wipe your phone every time this happens.
Here's what I do:
Since the device's connection is severed after the use of a certain amount of power, we can control the power management of the port that the device is connected to.
On WinXP:
Enter "Control Panel" > "System"
Click on "Hardware"
Click on "Device Manager"
Find the "Universal Serial Bus Controllers" section
Click the "+" next to that, and find the "USB Root Hub" that the device is connected to.
Right-click on the Hub, then select "Properties"
Click on the "Power Management" tab
Then, UNcheck the box that says "Allow the computer to turn off this device to save power."
This will prevent the connection from resetting. It's a quick workaround that works pretty well for me.
However, I ought to note that the changes should be undone after you're done with syncing the device, ESPECIALLY if you're on a laptop. Otherwise, you could risk a lot of battery/power usage within a short time, even if there is no device connected to that port.
Good luck, I hope this helps.
Cheers!

Please don't bail out because of that comment, i have been having this issue for a month and AT&T almost sold me another phone telling me it was the USB PORT.
I changed my phone setup dialing *#7284# and changed the UART to : PDA from Modem and same for USB (to PDA) modes. This helped get connected as before it would not even recognize the phone (computer would not do so).
I was am not sure if it is not the battery or charging circuitry, as others also reported, but my charging circuit is working fine and my battery charges 100% and last all day as normal. I can connect to the USB port and see my phone for a short while but it will suddenly disconnect.
But same as before it suddenly disconnects and will reconnect cycling continuously. I also believe it is the charge circuit because when it is charging, i hear the phone constanlty beeping from turning the schreen on/off. Same as when it is plugged into the usb port on computer.
Am tempted to buy a battery, but is can run the phone on the USB port without a battery in the phone. Problem continues without a battery...disconnecting and connecting to the computer.

I was plagued with this same problem, until I tried the above fix, and it works brilliantly! No more disconnects, great stuff.
It's pretty old topic but maybe someone has same issue and doesn't want to loose data. I had similar problem (couldn't connect to device, also couldn't install/uninstall any stuff because of no-space-available error).
I managed to download all pictures/documents via adb - worked pretty well. A sample command to retrieve all camera pictures:
adb pull /mnt/sdcard/DCIM
I have a really weird problem. My computer won't recognize my SGS2 is connected to the computer at all. Meaning no notification sound, no device change in device manager, nor any prompt to install a new driver. I've tried in both MTP and Mass Storage. What's even weirder is that it detects the phone in Odin mode and even installs the correct drivers. I've tried just about everything I could think of, such as the following:
-Cleaning the microUSB port with alcohol & new tooth brush
-lifting the microUSB connector slightly
-Using a toothpick to try to pick out any residue in mUSB port.
-Connecting while TWLaucher is set as default
-Using Wireless & Network setting > USB utilities.
-Taking out the sim card and external microSD card and booting & rebooting it.
-Restoring the stock Firmware
-Different wires, including an untouched mUSB wire that came with the phone.
-Different computer that doesn't have Kies or the said drivers installed. (Still didn't make a notification sound or bring up the "new device" prompt)
I just want to make sure I tried everything possible before sending it in for repairs.
EDIT: Oh forgot to mention that I had other problems before getting to this one. About a week ago Car mode would always activate by itself constantly. Even during use. Also the phone would refuse to stay turned off. After booting down, the phone would turn off. However, after some random amount of time, the phone would turn on by itself. During that time, connecting the USB wouldn't keep charging the phone. The phone would go between connected and disconnected randomly. Sometime off and on multiple times with in seconds. Other times would charge for hours and randomly stop charging. I've gotten the phone to charge whenever its connected now by cleaning the port, but the computer still can't recognize it as a device. Also the screen will randomly turn on, plugged in or not, and I have to manually turn it off again. However, if I turn it off right away it seems to lock up. So I have to unlock the phone the press the power button again to lock and turn off the screen. Don't know if this information helps.

Try another usb port, sometimes that helps or reinstall the usb drivers in Kies

My thought is that the USB connector get wet and stopped working properly. As fas as i know, USB connector is composed by 3 cables, one for charging, one for data transfer and another one to detect Car Dock.
It seems that Odin is using Car Dock cable (?¿?¿) instead of Data, so you can use Odin and not Data.
Also that would explain why car mode just kicks in by itself (short circuit between car cable and probably power cable).
I will also sent it to a SAT, since i tried everything via software....
I have the same problem. Try plugging into a mates laptop, see if it works on their one.

Hello,
Recently i've had some major issues with with my USB-cable, which i got with my SGS2 GT-I9100. The problem is that it simultaneously seems to malfunction after a small amount of time after i've had it plugged into one of the ports in my computer. I hear that "tum-tum" sound so often that it's literally getting on my nerve (you know that sound when you connect the USB to the computer and the computer recognizes device AND also unrecognizes the device).
I use my USB to copy many files between my phone and computer for safe keeping. It can sometimes go from 20MB to maybe 3.5GB worth of information (music, apps, pictures etc.).
And because i copy large files the USB was very practical, but now because it starts to act weird i cannot copy, which i really need to do. That's why i am asking for a good substitute instead to USB to copy such latge files.
If you know one, please do not hesitate to reply below.
And if you know what problem could've occured that could cause my USB-cable to "flicker" like this, please also reply about it.
Also because of my USB problems i can no longer flash ROMs and Kernels via Odin, but have to trust CWM Recovery to work flawlessly. And i like to have other options just incase and if the USB does not work i can't trust to make a Jig either. That's why if i know what problem there is with my USB, i can fix them/it or avoid the problem with another USB-cable.
Thank you very much for your time and extra thanks for replies
