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)
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.
Hi all,
So I have searched the forums and used to google to a solution but to no avail.
When I plug my new s4 into my laptop it recognises the device but doesnt not come up on windows explorer. The phone also does not give me the option to change from camera mode to usb mode etc like my nexus does.
I have installed all the latest drivers and even tried kies 2.0 which says it is not compatible with this device.
The s4 rootkit detects the phone and allows me to make a backup so the connection is there.
I think it may have been a setting I changed when I was unlocking the phone by going into the debug menu?
I have also tried toggling usb debug etc from developer mode. I have restarted the phone several times and my laptop and tried it on different laptops so I am sure it is an issue with the phone settings.
Thanks to all in advance.
Running windows 7 and s4 on 4.2.2
I found a solution for anyone who has a similiar problem.
One the phone pad type *#7284#
go to qualcomm options and mine was a weird selection. I changed it to MTP and ADB and it works fine now
This is just a suggestion, samsung drivers and keis do not get along very well, disable keis and try again, it will show up.
Ok, so I found a few older threads on this, but no tips in them seem to work in my case. I can't seem to get my S4 to see the PC/USB connection and prompt to select Media Device or the like. The USB icon never even appears in the notification bar. The PC recognizes connection (USB tone sounds) and shows device ready to use, but phone never gives the option. Doesn't seem to matter if USB Debugging is checked or not, or anything else that I can find so far. Here's the things I can generally eliminate:
2 different USB cables worked on wife's S4 on two different PCs. Neither cable or PC worked with my S4
Tried reinstalling Samsung USB drivers just to be sure
Cold booted phone
Tried unchecking and re-checking USB debugging (also tried with it unchecked)
So when we take in working fine on wife's S4, I'd generally guess that we can eliminate cable and PC from the potential problem list. Phone is currently on stock rom, but rooted. Outside of that and freezing VZ Support, Knox, and VZ Tones, no other modifications to the OS. At this point, I'm pretty stumped. Any suggestions on other steps to try?
The problem is your USB settings in the hidden dialers. Look for tutorials on how to enable them, and once found, type *#0808#, and a list of usb otions will come up. Pick any with MTP and they'll work again.
Worked perfect. Thanks muchly!

Not to threadjack, but...
On a related issue, win update tried to update my samsung ADP, etc drivers and failed. Ever since, I cannot connect to the PC. The PC doesn't even notice that the phone is connected. I tried the above fix to no avail (it is set to MTP) I uninstalled and reinstalled kies, tried troubleshooting the usb connection, ect...
Please help.

Try installing/reinstalling Kies, it comes bundled with all the samsung drivers you'll need
Tried that. Twice. To no avail.
But it is no longer a problem. I installed eclipse rom and it now works again.
Who knows what went wrong...
And now it's not working again. Reinstalled (dirty) the ROM without any change. Thoughts?
Hello to all,
I have at present the same problem as gnocko
Explanation:
I purchased recently a galaxy s6 ( SM-G920F), Roma G920FXXS4DPG2 XEF 6.0.1.
Some day after his(its) purchase, he(it) is not any more recognized by the pc. The notification of choice of the mode of connection is not present any more, he is notified a just man " load by cable ".
He(It) is recognized with smart switch and nothing near(on the side of) ring roads(peripherals) pc.
I thus have to make several manipulations separately:
- Change the mode USB in the " Options of development ".
- Activate the debugging USB in the " Options of development ".
- To Change cable, I used 6 different cables Samsung (functional on other smartphones).
- To Change of pc, I made the test on 5 pc different in passing for the installation of the driver
- Reinstall the Roma via odin (files taken with the links of the forum and all the wipes was realized).
None of these manipulations solved the problem.
The only moment when this one is recognized by pc, it is in mode(fashion) odin download.
The otg is functional.
Would you have an idea of the problem?
Thank you in advance for your answers.
