MTP USB Device Failed

I have tried this on both Win7 32 and 64 to no avail. I have tried different drivers, different versions of Kies, but I can never get Kies to see my TMO Vibrant. Not sure what else to try.

Same here. I don't know why others got it work. -___-

You need touchwizz to be running for it to work so if your using a different launcher switch back to tw and then give it a go.

Using Home Switcher I switch back to TW, I get the MTP screen on the phone for a few seconds and then it returns to the home screen. A dialog box on the computer says:
Device driver software was not successfully installed
MTP USB Device XFailed

I've had the same problem, when I plug my vibrant in and have the usb set to kies, it gets stock on the "initializing" screen on my phone. It locks the screen and nothing works. I have to reboot my phone every time. I've tried downloading all the latest software and drivers from samsung's website and still no luck.
Very frustrating.

Done all that, still gat Failed on MTP USB Device

same, spent a couple hours today trying to **** with this (uninstall, reinstall, etc etc) and I am getting the same error. giving up, just gonna wait

When o boot my pc on safe mode the htp installs but once i go to normal mode it wont.

try this
Restart your computer
Tap the F8 key after your computer initially powers on.
Once you see the Advanced Boot Options menu you can stop tapping.
Select the option that says ‘Disable driver signature Enforcement

That didnt work for me. Hopefully works for someone else

Try these drivers http://forum.xda-developers.com/showthread.php?t=728929

I recommend using odin to update if you can. I never thought I would prefer odin over anything until I used kies.

I get this (attached pic).
I've tried reinstalling kies and drivers several times.
Edit: The Samsung Android USB Modem eventually fails too.

I'm having the same issue. I'm using the stock firmware with the TW launcher and i've tried the USB drivers listed in the forums. Nothing seems to remedy this issue.

I am currently doing the install. Just install KIES and now installing the USB drivers I posted above. I am using Windows 7 64bit.. Then I'm gonna plug in my phone in KIES mode. If all goes well I will TeamViewer to everyone who have the issue here and try to help you out. Anyways wish me luck! Got a samsung interview in the morning so I'll be going to be in 2hrs..

For those who can't connect with Kies

After half an hour trying I have just found a working solution how to connect your SGS in Kies. Here is the deal:
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
I tried this both on x86 and x64 Windows 7 and it works for me.
I hope this will help! And I hope there isn't another thread with this solution. If there is - I'm sorry

i cant wait to get home and try this... another 10h to go
but if this helps ur a geniues

Will put this in the FAQ if we have some confirmations for its effectiveness

when i first bought my phone it worked with kies, but after flashing it to a different firmware there was nothing i could do to get it to connect. i had deleted drivers, re-installed, etc etc but nothing worked. what ended up working was putting the phone in download mode, plugging in the usb to both phone and pc, then putting the phone into recovery mode, and as soon as the recovery menu popped up my device was recognized and the correct drivers were reinstalled and all was fine again

If you still have this problem, please try my method and tell me if it works

I had issues and I also tried this method. But it didn't help
Last thing I tried was to format the internal SD. That did the trick for me....

The biggest problem with getting the phone to connect to Kies is two fold:
1) MTP application will ONLY launch from the home screen (touchwiz screen). NOT from any app. drawer / launcher screen
2) If USB mode on the phone is set to Ask on Connection, MTP won't launch due to the USB app. being open (see 1) above)
If you set USB to Kies mode and then ensure you are on the home screen of the phone with nothing else running, Kies WILL connect

Also remember the 16+ size extension bug.
So a full wipe on ur I internal sd card is a good solution just make sure u back it up tour hdd

I also did a "Driver recovery" from Kies and it worked after that. Although MTP driver failed to install for me in this case.

Make sure to update to the latest version of Kies ( Now 1.5.1.0074.45 ) as this version seems far more reliable when connecting the phone

I recently discovered that the culprit of Kies continuously trying to connect to phone was caused by wrong MTP driver selected.
Under WinXP
After phone connected in Kies Mode..Go to Device Manager/Portable device..
If you see a device labeled as "MTP xxx or Portable device.." ,wrong MTP driver or older driver has been used..For my case, a Microsoft 2004 MTP driver was selected.
To fix it.
1) Do a manual driver update..for my case ,i let the driver wizard to search automatically..this round, another newer Microsoft driver was found..in fact 2 of them.. after installing the drivers(Microsoft 2006 MTP driver,2 are listed..). .Now Device Manager/Portable device listed "GT-i9000" ,Kies immediately found my phone.
Driver name that worked are "wpdusb.sys" and "wudfrd.sys" found under \windows\System32\drivers\..

You must not understand English. The entire reason I posted a comment was to share how I overcame this issue, so that would mean I no longer have this issue

Probable Fix for Kies
Friends,
I have also faced the same problem (while connecting my SGS via Kies MTP was crashing). It used to work earlier so I started to remove Applications and data in the reverse order of Installation. After I removed "Dolphin Browser HD" and all saved bookmarks it started working.
This may be a probable solution if you also have Installed Dolphin Browser.

India.

2 different issues.
MTP crashing on phone is independent from Kies on PC cant detect phone.

i couldnt use kies either but i wasnt worried as i hardly have free time now..
this was a simple fix and now it workes perfectly for me.
sorry about the late replay.
thanks

I'm glad that it works for you

You might be interested in my little APK (SGS Toolbox). I first created it to have it read the product code from the nv_data file to allow you to check whether it has been modified after a firmware update. But now I added some extra options, of which one is the option to check whether there are new firmware updates available in KIES by issuing the same request KIES does when checking for new firmware. This way you don't have to connect your phone to your computer all the time to check for new updates in KIES. Note: It sends JM1 as the current firmware version to find the latest. I might send the actual phone's firmware version once I figured out how to find it. See: http://forum.xda-developers.com/showthread.php?t=778244

Thanks, I'll give it a try

Deleted. Wrong thread.

[Q] Kies doesn't work after Root!

Hi everyone!
I've got an Apollo (GT-i5801), and after a successful root using z4root, i can't use my phone with Kies. It worked great before root.
When i connect it to the pc, the phone is recognized as an SD card( fine!) but with Kies, the "Connecting" option stays there forever...
Any help?
Thx

Try it without sd card. you can't access your files with kies now but you can upgrade when it's time.

Froyo?

I've tried that way, didn't worked

i dont know if was martin tip, or an update on kies
what worked for me :
try to disconect the phone, reinstall drivers (do that after kies update, if you need to)
dont set the phone to ask on connection what to use (mass storage, kies, internet) but set it to connect directly on kies
start kies, and plug the phone
worked for me

Did you verified that USB Debugging was unchecked ? because when it's checked there is no connection possible using USB port neitherfor OS or KIES?

I am also facing the same problem with my I5801. Initially I rooted with z4root 1.1. version later I felt its because of the old version. Later I installed latest Z4root 1.3 version and re-rooted it but no use. My phone is not at all getting recognised (though I get a sound from my phone after connecting to pc but there is no option to choose KIES or Mass storage etc. It simply getting charged)
The KIES didn't recognise my phone even after connecting it to PC.
Later I tried
http://www.careace.net/2010/08/25/how-to-fix-samsung-kies-connection-problem/comment-page-5/
Though not of much use nothing happened.
Even I tried (Dial part in the below link)
http://forum.xda-developers.com/showpost.php?p=8667486&postcount=524
Fortunately this time my KIES recognises some unknown phone is connected but it mounts my phone in Memory card mode. Though I couldn't do much in this mode, this might help some of you to understand the problem deep enough to solve the issue. Thanks.
P.S. Though connecting to KIES is not of much use as we can back up data with some other apps but the major concern here is if in case (no hopes though) Samsung releases official firmware then we should have to use KIES to upgrade our OS version, then we will be in trouble.

After rooting with FuguRoot, Kies can't find my phone either. This seems to be a known issue but nikademus hasn't replied in his thread for some time now. Does anyone know why this happen and how to fix it? It seems a bit strange seeing how everything but the added su and busybox is stock..
Maybe some cache issue?

I can verify on that. After rooting my phone to make a backup with Titanium backup before upgrading with Kies, just to be on the safe side Kies doesnt work anymore with my galaxy3.
I tried unrooting the phone, but it did not help.
Strange thing is, that the usual information on the phone screen, saying that it is now connecting to the Kies did not show up. I did som trick like writing *#723572# (not pretty sure anymore what it realy was) and then setting it to modem and back to pda mode. Now I see the information saying on the mobile screen that it is trying to connect to samsung kies, but it still does not work.
I tried it on a virgin computer running xp sp3. I installed the newest Kies, than connected the phone, but now it says, that the connected phone is not in Kies (or Pc connect) mode, and I should change it to that. However the galaxy 3 screen says that it is definitely in Kies usb mode.
I will try later a factory reset and then an update through Kies to the latest fw. And after that a restore with Titanium backup.

Try unmounting your MicroSD card (Settings -> SD Card and Phone Storage -> Unmount SD Card) and then connect it to PC.

If you're on windows 7==> Kies, preference==> check: compatible with windows xp (service pack 3)

Windows doesn't recognize my phone

Alright, so I've been trying to figure out why Windows doesn't recognize my phone in Download Mode (attempting to get EB13) and I've now realized it doesn't even detect it in Mass Storage mode (Windows tells me a USB device was not recognized when I connect it)
Any ideas?
I'm stumped here...
Note: tried it on both x86 and x64 versions of Windows.

Download the latest drivers. As for download mode areu trying to use odin?

Check the "teeth" in where the cable connects to your phone. Some people have had them bend out of place.

Just downloaded them onto my x86 machine, and even when connecting my phone in normal mode (when it's fully on) it tells me device not recognized.
So at this point, I'm not even focusing on Odin, because nothing seems to be able to see my phone over USB.
I've even tried a different cable, but to no avail.
And yeah, I tried the Samsung EB13 download and I tried Odin. Neither could see it (just like Windows).
Other then this, it works perfectly fine. So it's not like I bricked it or anything.

Having the same issue. Tried multiple computers, reinstalling the drivers, and multiple USB cables. No luck. Makes things tough trying to get EB 13.

Alright, so I'm not alone here...
Windows actually seems to have just recognized it while powered up fully (and is currently installing the drivers).
Figure I'll let that finish and then try Download Mode again.
And then hope for the best I guess.
EDIT: It seems to be working now.
The Samsung EB13 utility is doing its thing in Download Mode.
Crossing my fingers it finishes without incident.

Uninstall drivers then install then reboot pc and phone then try. If reboot didn't solve the problem reboot phone and try again.
Epic 4g

Well, it seemed to be working.
But now my phone has a green screen and the EB13 utility is stuck on "FACTORYFS" and the progress bar says "Elapsed Time: 18sec.... 4%"
I really hope this didn't brick my Epic

anyone know where the drivers are for the epic

shud be somewhere on this site.. or on samsungs website.. its easy to just google..

Help someone here can such a problem. Tried different drivers does not help. Can not

Hello, I have SM G930V encountered such a problem. I want to update to 7.0 but when I transfer the phone to the bootloader and connect usb in the task manager on the drivers it weighs the exclamation mark! I tried different drivers but without successful in Odin does not show com port! What do I need help?

Ok, going to take a crack at this. If you have the drivers installed, when your phone is plugged into the pc, delete the exclamation mark, unplug your phone and plug it back in.
Should install the drivers.

It sounds like he plugged his phone in to the computer prior to installing the drivers, so it's now installed as an unknown device.
Windows won't search for updated drivers until the unknown device is either deleted, or he goes in and manually updates the drivers from the device manager.
Deleting it and letting windows install is by far the easiest way to accomplish this.
I know my replies can be long, but would rather give too much info, than not enough.
