As per the title, device manager doesn't change when I plug the phone in, tried two different computers and two different cables, flashed the stock firmware back, and still nothing.
It charges when I plug it in and SOMETIMES brings up the MTP-Initialization logo thing, but never gets any further.
Is my GS2 goosed yet again?
Edit: Tried on my PS3 as well and still charges, but won't ask to mount the SD card or anything, so I'm back to my trusty HTC HD2, wondering whether I should sell the GS2 once it's repaired and get a Galaxy Nexus...
Hah, another HD2 veteran, it's like everyone from the HD2 forum is now here... even the devs. Anyway, may be a stupid question, but are you always trying with the same USB cable?
Disable usb debug mode
Sent from my GT-I9100 using xda premium
Tried two different cables as stated in my OP, and it doesn't matter whether USB Debugging is on or off. I'm taking it back to the service centre after work today, and I'm probably going to sell it after.
I've had the camera go.
I've had it not vibrating at all.
I've had problems with spots on the camera lens.
I think I'm going to put some money to the sale of it, and get a Galaxy Nexus, hopefully the built quality will be at least a little better...
Solution is in the phone
Dear All
Following are my observations and possible steps to
1. When the phone is upgraded to Android 2.3.4 and above (mine is 2.3.6) Kies stops recognizing the phones and USB connection / Serial port connections etc get reset on the phone
2. Even if proper drivers are there on the laptop (mine is Windows 7 64bit) they are not recognized
3. Device Manager shows "unknown device"
4. Updating the driver also does not result in any help
5. solution lies in the phone
a. key in the dialer *#7284#
b. it has 4 option there..
UART (MODEM/PDA)
USB (MODEM/PDA)
c. For USB. select the PDA.if it already selected to PDA. reselect it by select MODEM and then PDA again.. Only change the USB setting.. andthen press back. try reconnect (thanks to napi1 @ androidforums.com/samsung-galaxy-s2-international/447145-sgs2-kies-not-syncing-os-2-3-5-a.html#post3484588)
6. The Laptop will start recognizing the required drivers and install them
also
Phone is not recognized by laptop when it is in USB debug mode, MyPhoneExplorer does not recognize when it is not in Debug mode
Hope this helps

Thank you !!!
Unbelievable! Thank you soo Much!
Helps also on Mac 10.6.8
Thanks a lot mate..I was afraid that i'll have to take it to service center. This helped me.
thanks people!...even i had upgraded to 2.3.6 and usb mode just wouldnt work....
this solved that problem though..
Fantastic tip!
It worked! Now my S2 can be detected by the PC.
Thanks a million!
Doing a factory reset after backing up data will solve the problems.
Still Hasn't worked for me. I'm getting no USB function other than Charge. Its working as if the USB isn't plugged in at all.
Is there anyway of reinstalling the MTP application on the phone? When i find it through App manager its showing with no size and no options inside (clear data or clear cache)
Kies isn't working as far as the phone is concerned there is no USB connection at all.
I know ICS is coming within a few days for GS2 owners, will this clear the problem???
So frustrating.
Thanks in advance if anybody can help

same with mine. mine still doesnt work with the dialer *#7284# and with debugging off or on. ive unistalled and reinstalled the driver serveral times and nothing and this has happened to me on my hero and my sgs2 dozens of times, its so annoying =[. at one point i manged to get all but the usb storage drivers installed. what else can i do ???
Same problem
Same problem here, tried everything (to my knowledge). Someone told me it had to do with the battery overheating because I had use the charger from another phone. For about 2 days my phone would go on vibrate randomly and started the connection process (like a usb cable was connected). It could do that non stop for a few hours. Now that Im back to my original charger, it stoped, but still can't connect to my pc.
I tried on 3 diff PCs with diff version of windows...
I've tried everythin, debug mode on/off, reinstalled Kies, drivers, did factory reset, but nothing.. when i try to connect my SGSII to Kies, it writes "Current connection mode not supported by Kies".. I'm on Lite'ning rom v2.2..
If you're running a custom rom, why would you want to use Kies ? It's awful. There are so many other apps that have the same functionality as Kies (tho granted not one app that does everything Kies does) that work perfectly with custom roms.
Only reason to use Kies would be if you went back to stock because you wanted official ICS OTA or similar IMHO.
I did a backup with Kies, now my all contacts, sms, videos, music, calendar are in this f***in' backup file.. :| I have an awfull headache Or i can do a restore with another app, will it be compatible with Kies's backup file?
same problem. USB connection to PC will only charge. Recently updated to 2.3.6.
Tricky one.
----------EDIT---------
it worked ok after rebooting my PC. Must just be general crapiness.

Won't work on my samsung galaxy s2 (ICS 4.0.3) - windows Xp (sweet)
Disclaimer:
I've searched all over the forum and found few close to my problem but this seems different
Background:
I recently flashed my Galaxy S2 International version with CM9 nightly build. Since then, when I turn off the phone and put it for charging, the battery charging animation stays like that till the phone is fully charged unlike the stock ROM where that animation disappears after some time.
Simultaneously I've noticed something else, when my phone is plugged to USB cable attached to my computer, a pop up appears at the bottom right (notification area) which says "USB Device not recognized" and in Device Manager it's listed as "Unknown Device"
I ignored it thinking that it might be an issue with the CM9 Build as it's not fully functional. I've had the phone that way for around 10 days.
Recently I thought of switching to XXLPQ(Official ICS Update) and I got into Download Mode but Odin doesn't see the phone. No "communication" establishing between phone and computer.
I also had CM7.1 on SD Card and I thought flashing that old CM might bring my USB functionality back.
So got into ClockWork Mod Recovery and flashed it. Flash was successful. But now phone is in boot loop with "Samsung Galaxy S2" with an exclamation.
If I try to press and hold the power button, it comes back to that battery charging screen even though phone is not plugged to either USB or charger.
I can get into download mode(Odin can't see the phone) but not into Recovery Mode.
Three things that I see as of now on my phone are the boot loop I mentioned above or Download Mode (but not recognized by Odin) or Battery Charging animation.
I'm sure there's nothing wrong with USB Cables or Drivers or Kies or anything else. Because my brother's S2 works just fine which is on "Stock ROM".
I need help. I'm sure that CM9 nightly broke that basic USB Device functions on the phone.
Please let me know if there is any alternative for recovering my S2. I know that the worst is, it goes to Repair Center.
But I hate to give up on this!!
Are there any other tools or recovery softwares which can be used to re-flash the phone other than Odin no matter what screwed up state the phone is in!?
Deleted - sorry, hadn't read your post properly.
firstly i want to ask does your phone charges? if it does it sounds like u dont have development option enabled.. or ur usb port is broken.. if it doesnt charges then im pretty sure ur usb port is broken...
about the recovery.. can u use ur SD card on ur brother's SG2 and put stock rom into it? and then insert it into ur SG2 and try flashing it throught CWM

Thanks for the response Warrez!
- Phone charges (but that battery charging logo stays like that)
- When I flashed CM9 nightly I'm sure I haven't checked or played with Development option (It's not enabled)
- And last, I'm not able to get into Recovery Mode as well (already mentioned above)
Any other inputs!?
I have the EXACT same problem
Me too exact same problem .
I've confirmed my setup is fine as it works with Odin for my tab 7.7
Exact same issue, stuck at Samsung logo with exclamation mark. Can't get into recovery, can get into download but computer says device not recognised .
I was running Slim ics at the time then about to switch to cm9 and siyah kernel

Well.. I made some progress in last few days! I've taken out the battery and got into Download Mode. I was holding buttons and my brother inserted the battery. What I did was I powered of the system and connected the phone while it was in "Download Mode". I waited for some time.. Say more than 3-4 mins.
Rebooted my PC and once it's back it wasn't saying anything. For my surprise I see the "Yellow COM" established in Modem. Without delay I grabbed recovery ROM which is posted in one of the sticky threads. Flashed the phone.
Now, it got little interesting! When the phone is booted back post flashing it shows that "MTP Device" even though USB Cable isn't plugged into it!
When I turn off the phone, it either reboots back without hesitation or ends up at "big green battery charging" animation!
To get back into OS, I have to get into recovery mode and then I use "Reboot System"!
And that "USB Device malfunctioned or not recognized" thing is intermittent.
At times it says that and at times it establishes "COM connection" in Odin.
I re-flashed old bootloader thinking that it might be a phone's basic operating driver issue. But that didn't solve the issue!
I've even flashed latest stock European ICS Firmware.
And with ICS, things got even more interesting!
It started throwing up new message "Charging Paused due to over voltage"
What I'm sure of is.. It's definitely got to do with CM9 ICS. Because when I was on beta official ICS before I switched to CM9 Nightly phone was working like a charm! As soon as I flashed CM9 Nightly, I started getting that "USB Device Not recognized" issue with the battery irregularities.
I wasn't sure how I could get the phone recognized in Odin. Hastily I flashed CM7.1 on CM9 compatible ClockWorkMod Recovery enabled Kernel. That is when the problem got more complicated!!
I'm about to give up and pay someone to fix it via Jtag.
I've tried several computers, several cables , multiple reboots and everything else.
Windows just still says usb device not recognized so the phone must be corrupted somewhere.
Please change ur USB cable, i had this problem n its only frm the cable.
I don't believe this.........
I had tried two other cables ( a nokia usb>micro usb and another one ) as i had lost my samsung usb>micro usb lead and both those said unrecognised device....
I had just given up, ordered a jtag repair and then my old dear finds the samsung cable!!!!
Bizarely it now recognises the phone.
Hi Guys
I am having the exact same problem and am still looking for a solution.
My phone is not recognised by the PC after installing CM9 Nightly and now I am stuck until I can get the device driver installed again so that I can use Odin.
I am using the official Samsung USB cable which worked fine until the CM9 flash.
I am assuming this is a common problem so am hoping that somebody can supply a fix asap.
Any help will be appreciated
Ta
I had the almost the same problem .. I took it to the place I bought from .. and fix it .. they told me it was a hardware problem ( I remember with the hard disk .. I forgot )
The same thing, after using the Custom ICS LPQ roms!!
Now there's no way i can't use Odin to flash official rom!

Last time I checked.. My phone is getting detected in Odin. But not always! Every 5 attempts it sure is seen by Odin 2-3 times. And it's on ICS 4.0.3 XXLPQ with "Charging Paused high voltage detected" message even though it's not plugged to charger or USB Cable.
My brother advised me to leave the phone that way and wait till it goes dead and then keep it dead for at least a week and then try charging it fresh with phone's stock charger. Now 5 days passed and I'm waiting for another 2 days to try this out!
Cheers,
A.

Gee.. Try this! Take the battery out of the phone and press the power button for few secs with the battery out. Take someones help to put the battery back while you are holding the download mode button combination.
When you get into download mode, leave the phone that way and do not plug it to the USB Cable. Power off the PC and wait of 3 mins. Now connect the phone to the USB Cable while the PC is still off and phone is in Download mode.
Turn the PC on and wait for till it reaches desktop and then give it 3-4 mins. Now launch Odin. If you have any luck you should see that "yellow COM"!
The same procedure worked for me! If you happen to see that "yellow COM" on Odin don't delay anymore. Just flash any stock ROM. 2.3.6 or 4.0.3!
P.S.
Odin may not see the phone on the first attempt. If so.. Repeat the steps for 2-3 times
All the best!
Cheers,
A.

Hi everyone,
I am new to this forum, i have gone through a number of post to understand how to root and flash my tab 7500 with pershoot's EXPERIMENTAL ROM. After I install everything in the tablet is working fine but when I connect to pc it is not detecting as a storage device. But the tablet is charging when I am connecting to PC (This was new, it never charged with previous official ICS). I tried recovering to my previous official ICS by recover option in CWM. Then tab is getting detected by PC and it is not in charging mode.
Is this some issue with the firmware? Or am i missing something simple? Please help me out..
I have tried searching for this issue on internet but couldn't get any useful info regarding that.
I am experincing same issue, but with ics stock ROM, which I have flashed from 3.2 stock rom. When I connect the cable to pc, tablet does the sound, but won't start the mtp server, and computer cant see it.
Problem solved
Seems like this is a small setting that needs to be selected.
Go to Settings>Storage>USB Computer Connection and check MTP checkbox.
After I did that my system is detecting it as a storage device and also charging it
@kosciCZ : You might also want to check that setting.

I am afraid that this is not that case. I checked it multiple times, tried the other option, but it still does nothing.
This is what happened. I want to upgrade my Samsung Galaxy tab 10.1n from 3.2 into 4.0 . I try to root and somehow I do some stupid error.
The bootloader screen become rolling. I found the solution from this thread http://forum.xda-developers.com/showthread.php?t=1555984 and it runs perfectly. my bootloader become normal.
But another problem come out after that. my PC can't detect my samsung through USB. any guide for this problem??
Change usb port or cable
Dont use usb hub
Reinstall kies 2
And retry
Sent from my GT-I9300 using xda app-developers app
noob here.
Galaxy Tab 10.1 P7510 Wifi
I have a similar problem to the above.
When I connect using the usb lead to the pc, nothing happens. I have reinstalled the drivers (both with and without Kies 2) and upon connecting the usb it acknowledges a connection and goes through some steps and proclaims the device is installed and ready to use. Except it's not. It doesn't show up in My Computer or when I remove and re-connect the usb, there is nothing - the same as before I resinstalled the drivers. Kies cannot find it either.
My issue is further matched by the above issue as I also followed the same guide as above. I previously tried to root the device several times and each time the recovery screen was doing the rolling / flicker thing. So I returned to stock. But inevitably I would get infuriated by all the things I couldn't do.
So when I found the guide http://forum.xda-developers.com/showthread.php?t=1555984 that further linked to http://forum.xda-developers.com/showpost.php?p=27830023&postcount=41 I was thrilled because I could finally read the Recovery screen.
So I proceeded to root the device as per http://forum.xda-developers.com/showthread.php?t=1474971. This was working fine with one exception. Which was that after the screen went into sleep mode and I pressed the power button to wake it up, the tablet was in a variant of the rolling / flicker screen. This happened every time. I repeated the rooting process making sure to wipe data / cache / dalvik.But it remained.
So I became adventurous and decided to flash an experimental CM9 sourced from droidbasement.
And that is where I am now. Unable to enter sleep mode and unable to connect to the pc to return to stock or try different roms.
Any suggestions or help welcome.
perhaps I should have opened a new thread but wasn't sure. please advise if so.
I used a different usb port and the pc could find it.
Now back on stock.
re:
Go to settings>labs>. Uncheck USB error (don't know the exact english terms)
guys I am having an issue related USB connectivity .. since yestarday whenever I connect my S2 to computer it says USB device not recognised .. I tried connecting and disconnecting .. several times .. then after I think 10 or 11 times it connects normally .. ( as media device) .. then today .. it is having same issues .. I tried connecting many times .. but today .. it doesnt connects .. it charges normally on USB but no USB connectivity ..help guys
You need to look at PC side stuff first. Uninstall Kies, reboot the PC, redownload a new copy of Kies, install it (it has the drivers you need), reboot & try again.
Then clean the port on the phone & if it still doesn't work, replace the board/port (even though it's still able to charge, it sounds like this could be the issue).
I am having the same issue ... I came to the conclusion that it is a hardware issue... Even though ït first happened after messing up with fast charge toggle in some rom.
Nor adb nor odin works
Advices before you go to any center (because yours seems to have worked more than mine ...the 11 times, after the problem first occurred ) :
Try different cable... Firstly.
Try to switch from mtp to ptp a couple of times with the device plugged in.
Try reinstalling drivers...
Try disabling and re-enabling usb debug setting while in mtp .
today I tried to connect the phone .. nd it connects normally .. I dont know what was wrong .. well its fine now .. thnx for ur help guys ..
