"Unknown Device" after uninstalling Kies >.<

i hate Kies!!!!!!!!! it just died on me >.<
now when i plug the phone to the PC it shows up as "Unknown Device"
if i connect to another computer, then it works fine.
the thing was working fine until i tried uninstalling Kies to install a newer version of Kies

Kies is the worst piece of crap. It is incredible Samsung can not get such a simple thing right!

i found the solution for the problem ...if you are using any of launchers from market launcher pro or awd launcher u need to switch back to stock launcher and restart the phone after u reboot the phone with stock launcher simply connect ur phone to computer after that ur pc should have no problem finding ur galaxy s ,np

Why does it say: This device's version cannot be updated?

it's not necessary to reboot the phone
just run TwLauncher and it works right away, as long as the USB in the phone is not set to Debug mode.
The problem i was having was with Kies and USB port in the PC

It doesn't appear to be anything to do with the phone itself.
I just plugged my phone in and got the "USB Device Not Recognised" error message.
I unplugged the phone and restarted it, but my computer is still flashing up the "USB Device Not Recognised" error every few seconds - without the phone connected!
I think the USB drivers are seriously flawed. I'm sick of reinstalling them just so I can connect my phone, which has become my standard way of resolving the issue.
Either that, or I've had to completely uninstall and reinstall Kies, a number of times, which usually works for the first few times I plug the phone in before failing again.
Pain in the ass.
I'm sick of this - and I'm kicking myself - as I suspected Samsung just didn't know how to provide software, based on lots of stories that seem to float around online about them.
I wish I'd stuck with HTC now.
fyi, I'm running Windows7 64bit, which seems to be a common platform to have problems with.

i only use Kies to check for Official ROMs downloads
i don't use Kies for anything else
all my syncing, calendars and contacts are handled online on Google

Connecting via USB or Kies not working

Hello.. i downloaded and installed Darky's rom on my Samsung Galaxy S GT I9000 it maybe isn't associated with Darky's rom because it worked after applying it.. but as of few days back i'm unable to get mass storage connection, nor Kies recognizes my Galaxy..
when i click mass storage on Galaxy, and click 'Connect USB storage' i can hear sound it's recognized on my pc, but two drives do not appear on my Windows 7 and i'm unable to do anything!
i tried mount unmount external sd card, i tried debugging usb mode, nothing helped. i downloaded, installed and uninstalled latest Kies, nothing works. Please help!

anyone? ......

Remove Kies and all Samsung driver s reinstall .
Backup data and factory reset .
Remove deadly rom .
jje

I've had problems in the past with crap aftermarket data cables. I never have a problem connecting with the stock issue one. But even then, if you hit the install driver button in the tools section, complete the install and unplug and replug the cable, this can also help connecting with the aftermarket ones.
And I know this may sound dumb, but did you uncheck the USB debugging and put it on the home screen? Just a thought.

usb cable works. i tried factory reset and reinstalling kies.. it appears all drivers are ok as shown in screenshot:

however, i'm still unable to remove my rom, and still cant access mass storage mode. it's not working with kies either ..
HELP!

come one guys

I have the same problem, nothing on google that helps

try using the stock launcher, not the one from darky's
since kies won't be able to connect if there are some other processes running in the background
let me know if it works
edit:
im running Darky's 10.1 and i just connected on kies using the stock launcher as i suggested
just force stop "launcher" and start using TWLauncher, afterwards you will be able to use Kies
Cheers!

thanks for the reply,
In the end it worked, I just had to disable / enable the phone from the devise management...
like this
"
Start Kies, put phone's USB settings in Kies mode. Connect your phone to the PC. Wait until MTP App show "Connected". Go to your PC's Device manager, find Portable Devices and select Disable on GT-I9000. Do not wait for the disabling process to be completed, just disconnect the USB cable. Now connect the USB cable again, wait the MTP App on the phone to show you the message "Connected" and choose Enable on GT-I9000 in Device Manager. After a few seconds your phone should be ready in Kies

[Q] Win8 mounting my N4 without a drive letter. Help?

Ok so I am having this problem with my Nexus 4 and the way it is being mounted (if thats the right word) to Windows 8.
I have used the WUGS root toolkit to root and unlock and whatever my phone so I have done the driver thing that comes with that (sorry im a noob) but even before that I was never able to get my N4 to mount "with a drive letter" (if you will).
Here is a screen shot to help explain,

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
If you will notice I have Windows (C and SSD (D and if i were to plug in a USB flash drive it would be assigned a letter and it would show up. For whatever reason it would seem my N4 is being treated as a camera or some other type of device because It is not being given a drive letter. Instead the weird external HD icon is there and then the harddisk icon labeled Internal Storage.
Some things i have tried, or know i have set: Media Device (MTP) is the selected mode on my phone, i have tried it the other way to no success. my phone does have android debugging enabled, I have tried resetting the windows autoplay settings and selecting a different option (before it auto opened explorer to the internal storage folder).
I am currently running Paranoid Android 3.60 however I had the same problem since the day i got my Nexus 4 with stock everything on it. I believe its an issue with the way my windows 8 computer treats it.
If anyone can help me that would be greatly appreciated. thank you!

I think this has to do with it not having mass storage mode. So that means that a computer will only detect it as a media device, not a USB storage device, and so it isnt mounted, it is accessed. If it was mounted, it would have to be unmounted from the device from which it is connected to, and if it was disconnected, you wouldnt be able to access the files on the phone itself.
Well thats why i think it doesnt mount with a letter.

This makes some sense to me, but can you elaborate on how i might get my computer to mount my android device? is there a reason it was set up like this? Is it my phone or my computer that is the cause? Anything else you can tell me would be great. Thanks

Nothing is the cause, its just how it interacts with a computer, so neither the computer or phone are at fault, its just how the tech is made. I tried googling for you on how to get a MTP device to get a drive letter, but its getting late for me, and im coming up with zilch. I hope someone else can help you out.

hmmmmm, that seems like a flaw in the tech. why did they develop MTP mode / why do we even use it if it lacks the ability to mount it to a drive letter? im assuming there are benefits I am not aware of. Thanks for your help. Ive been doing googling as well but havent come up with anything. I have a little more knowledge on the issue thanks to you and so I will try my searches again. THanks.

Right click - uninstall, reboot, reinstall drivers.

Same problem here!
My G2 is recently updated to 4.4.2.
I have tried on several computers, different ports and no help.
On the first connection to a PC not connected before windows reports "USB device not recognized" problem.
After that every time I connect the phone to the same computer the phone itself only recognizes that it is using USB charging mode, it does not recognize the computer connection (known by the USB icon on android system tray) even with "Ask upon connection option checked".
Even when I manualy change the Android mode in Settings --> PC Connection from MTP to PTP or even LG software, nothing happens.
Definitely there seems to be a problem with the phone, but I don't believe it's a software but a firmware problem.
Please help if anyone knows what to do.

[Q] Cable data transfer issue - Can only pass data in fastboot

When I plug my Nexus 4 into a PC (only tried Win7 so far but multiple systems) Windows reports 'The USB device has failed, please remove device'. It repeatedly tries to communicate with the Nexus 4 while plugged in and connects and disconnects every few seconds but at no point is recognized as a Nexus 4 or do I get a chance to install drivers. This occurs with USB debugging on/off, MTP on/off, CWM/TWRP USB mounted or not. I have tried various ROMs all with the same result. It still charges though.
I recently changed the USB daughterboard as the socket was becoming temperamental while charging. I can't remember the last time I transferred data with a cable as I normally use bluetooth, wireless FTP etc so I can't be sure the problem has only been occurring since installing the new USB board.
Interestingly enough, I discovered after not being able to boot a ROM, that I could still push data to the device via fastboot. To me it seems if the hardware was faulty then it would not allow data to pass in any mode. Correct me if I'm wrong but as far as I know USB always uses pins 3+4 for data and 1 + 4 for +5V and ground respectively so it's not like the hardware is being used differently.
I have ordered another LG USB daughterboard along with a new battery as mine is on deaths door, so I'm hoping this new USB board will solve my problem...
Do you know why can I only pass data over the USB and get the device recognized in bootloader using fastboot?

Have you checked your usb in device manager when you're normally booted or in recovery? It uses different usb drivers than when you're in the bootloader. Check to see if its a driver issue.

This is half the problem. Because Windows enters a sort of loop where it keeps trying to recognize the device, it does not show up for more than a split second in device manager and when it does, it is recognized as unknown device. If I am fast enough to right click on the unknown device and try to manually point drivers at it, Windows tells me the best drivers are already installed. Obviously Windows has no idea what my Nexus is at this point.
I have connected in bootloader and the phone shows up normally in device manager as Android Device etc. I have updated the drivers manually pointing Windows to C:\android-sdk\sdk\extras\google\usb_driver but this does not help trying to connect in fully booted MTP mode when the recognition loop starts again.
I have been working my way through this thread with no luck so far. Other people appear to have had the same problem and just given up.
I am going to try my Nexus on an XP machine tomorrow and see what happens.

I recommend using the nexus root toolkit and following the driver installation guide. I've had similar problems in the past but reverting to this program and following the basics has always led to working results.

Solved!
Ok, so I know this may not help many people apart from simply reiterating the fact USB sockets do fail so if you get stuck with Windows recognizing the device bear this in mind. Although one thing I have learned is that it is possible for such a failure to occur which allows data to still be passed in boot loader but not in MTP mode. I would still be interested to hear if anybody knows why/how this is possible?
After hours of trying different combinations of peoples methods of installing drivers It turns out the USB socket/daughterboard was to blame.
I replaced both the USB board/socket and battery and my Nexus is like a brand new phone. As soon as I plugged it in to my PC (using an old non LG cable) Windows recognized it, installed drivers and mounted it ready for me to browse. No manual driver installation required. Data can be transferred normally. It just works as I expect an Android phone to.
Thank f**k for that
