Morning all.
As of yesterday, my S2 won't connect to any pc in mass storage mode.
At first it connected as it should, but after about 5 minutes - before I'd transferred anything - I got a message that windows couldn't recognise the device/driver installation unsuccessful.
Since then I get this message immediately, have tried 4 different pcs.
Would seem the USB drivers are FUBAR somehow, but MTP via Kies works, as does Odin.
I've tried a full factory reset/reinstall, previous backups - stock and custom - removed, reinstalled and updated Kies, cleaned the USB port on the phone - nothing doing. Have tried stock kernels, Siyah, Nimphetamine - nothing. Currently on XWKL1, custom ROM (krinyo's SlimROM) with Siyah 2.6.3+
Also tried uninstalling various USB ports on my home pc, but stopped when I discovered it was the same on all pcs.
It's not the end of the world - I have bluetooth and my microSD - but it's a PITA and I'm out of ideas.
Many thanks for any help/suggestions.
Have you cheched if USB Debugging is enabled or not?

Yes, forgot to add that, sorry. Tried with and without, no difference.
Tried changing the usb cable?

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

Maybe this can help
Getting a Service Mode FC when I enter that code in the keypad.
Will try it with an older backup.
Edit - tried it with a backup of CheckROM , 2.3.6. No FC, PDA already selected. Tried 5c above, still no good - unknown device on pc..

No. Can't see that there's a problem there if Kies and Odin connect OK.

Bugger me, it was the cable....
Bought a new S2 yesterday - nice to have a backup, and the Nexus is meh - and tried the new cable on old S2, everything fine. Old cable on new S2, no good for USB but fine for Kies and Odin as mentioned before.
No idea why it should be like this, but sh*t happens. Easiest solution is often the best!
same problem happened to me too
I have the exact same problem, tried everything like OP, even new cable still same issue...any ideas?

Hi guys,
I have a problem that's fairly common but I can't get it right
I can't install new drivers for my SGS2, my pc/laptop don't recognize it anymore.
I have flashed an ICS rom before so I also tried the Nexus S drivers, no success.
I have tried to work with Android SDK manager but since my laptop can't find my phone, it won't find it as an adb device.
I managed to get back on 2.3.3 via CWM manager but my USB jig also doesn't work anymore.
I have tried everything regarding Kies and new drivers so I'm pretty much out of hope... Anyone with suggestions?
You could use mobile odin, also if you flash back to ics you can reset counter with triangleaway and then flash back to gb

Problem is that I can't flash back the old bootloader..
I think the logical step would be to try another PC, given you've tried everything else & nothing has worked.
You could also maybe try Heimdall (search for it on here).
Also, if you haven't tried different USB cables (in particular the one that came with the phone), give that a shot. Also make sure you're connecting the phone to a powered/mainboard USB port & not a hub port. Also, try toggling USB debugging in your phone settings.
That's about all I got. Try these things if you haven't already, but definitely try another PC.

I have tried different ports with different cables, different pc also won't install the drivers.
Usb debugging on/off doesn't work either.
Going to try heimdall today but it has something to do with my phone since I flashed so many files before with my pc and with my laptop.
Will post after I tried.
Yeah it sounds like a phone issue given you have been able to flash firmware with that PC previously. Good luck with Heimdall, fingers crossed for you.

Nope, heimdall can't recognize my phone either.
Running out of ideas here.
I guess there isn't an option to flash the old bootloader other than Odin huh?
Unfortunately Mobile Odin can't flash bootloaders yet, so Odin (and probably Heimdall) are your only options. Either way you're going to need USB.

My PC recently stopped working properly it connects but always fails flashing via Odin, I managed to set up Odin etc on GF laptop so at least I can use Odin if needed. Could you not try restoring your PC to earlier date and see if that works or uninstall everything to do with phone, kies, Odin adb etc and do a fresh install of everything

My phone doesn't connect at all.
I have tried uninstalling everything including drivers and such via USBDeview.
The problem lies with the phone itself I think, not my pc.
I think I have found the problem.
I think my USB port from my phone is broken.
I will try to reset my binary counter with Triangleaway, then flash back original firmware without root and then send it for repair to the Vodafone shop!
Hope this works

I have the same problem. I came from CM9 and now I cannot connect my phone to the PC. I am using CheckRom V6.
Do you think it has to do with the bootloader? Or might the usb port be broken as well?

Yeah I think that it has to do with the bootloader, but a broken usb port is also a common problem.
I still have warranty so I will just let Vodafone repair it.
If my pc still doesn't recognize it after that, then I'm screwed.

Ok but if it is a bootloader problem, we should not be the only ones having that problem.
I do not think I can send my phone to repair, since I am abroad for another few months.

Correct, I have searched the whole internet and there are some others with the same problem with the bootloader, but they can connect their phone and install the drivers I guess. I have tried everything regarding new drivers and such so I reckon that my usb port is broken.

Ok. So i think mine is broken aswell. I tried everything with the drivers, but my pc just says: USB device not recognized. Have you tried cleaning the port?

No I haven't tried cleaning it, do you know how to do that?
And yes my pc says exactly the same.
Ever since Kies got updated (a week ago), i cannot connect my Galaxy S2, and therefore cannot update my firmware through it. Every time i connect my S2 it just says Connecting... and stays like that. The funny thing though is, if i have a lock on my phone, it will detect the phone and tell me to unlock it. After I unlock it, it does the same thing again.. Connecting...
Any help?
No personal experience but try to reinstall Kies
Sent from my Galaxy Nexus using XDA
Tried, but it didnt work. Tried installing it on other PC, also doesn't work. Kies detects Galaxy S and S Plus, but cannot detect S2. Before the update though, it didnt have any trouble. I even tried with the older version, but that wont work too...

Do a factory reset, restart your Pc and launch Kies first then connect your mobile to ur pc .
This doesn't work either... Any other suggestions?
And yes USB debugging is turned off. I tried turning it on and off but it DOESNT make the phone connect to Kies.

Hmm. Ok, try entering *#7284# into the dialer. This will bring up a service menu. USB should have PDA selected. If it doesn't, select PDA. If it does, change it to Modem, then back to PDA. After that, try your USB connection again.

Does the port work at all? Will the phone charge?
If so, can you plug the phone into your computer via USB and start an ADB shell?
Yes yes the port is fully operational and i managed to connect the phone to Kies finally with just removing the SD card. Still not sure why it wouldnt connect with it...
Common Kies problem answers .
One use the SGS2 USB cable
Two connect only to a mainboard USB port .

Hey!
I recently Rooted my Galaxy SII, I'm running 2.3.4 but recently my device wont connect Via USB to my Window's 7 Laptop, I get the Connected sound effect on the Laptop and it Disconnects 2 seconds afterwards, I don't have enough time to install drivers or anything like that before the phone actually Disconnects again, Anyone have the same problem or can help? Its really Pissing me off
As always first is to clean the usb port .
Second is to use Samsung cable .
Third is to only connect to a motherboard port .
Fourth make sure that Kies or the usb drivers are installed first try a rinstall .

Which ROM are u using? Did you check the thread if there are known issues? Does your phone indicate a USB connection?
It's really weird.
I've tried it on three different computers (All Windows 7 though)
But it used to work on all three (except for when my desktop USB-ports ****ed themselves up)
I'm beginning to believe the outlet in which the USB cable goes into might be damaged.
I'm about to flash full Stock firmware, cause that's the last time I remember it working (like 3 months ago), and see if it works.
Any other tips?
Currently on WanamLite 11.4, and been flashing back and forward to Cyanogenmod using CWM flashables.
Clean phones USB port first
Second install USB drivers .

Tried installing latest stock LPD firmware, still doesnt work.
Also tried "cleaning" the USB..
Phone must be broken..
**** I cant be bothered with this ****!
I suppose I'll have to wipe every trace of any flashing and send back to Samsung

Okay, won't help me any at all now though.
I flashed stock, lost root (i'm so stupid) and now since I can't connect the phone to my computer, I can't get CWM back to restore my backup.

Seems a bit weird, have you tried using another cable?
I almost bricked my phone once because of a damaged cable...
Cheers,
Stefan.
Try cleaning the contacts between the battery and your phone.
Did you fix your problem?
If not, what exactly happens when you plug it in to your computer?
If "something" at all happens, then you may just need to switch the internal USB switch to use PDA and not MODEM in the PhoneUtils hidden menu. Make sure both USB and UART is set to use PDA!
Dial: *#*#7284#*#*.
did u try to erase kies and install only driver?
