Greetings.  I had this problem and went through all the forums and advice about formatting cards, resetting to factory defaults, etc.  In my case, I discovered that the problem was an invalid filename created by Foursquare.  In the /foursquare/cache folder there was a filename that clearly should have had a .jpg extension, but did not, resulting in a filetype of something like ".%FFIEJ2_VS%20" 

Deleting that file fixed the problem.  My hypothesis is that the MTP application scans the SD cards for files, looking at file types, and when it comes across that nasty filetype, it crashes... restarts... crashes... forever.

My suggestion is to look into your SD card files (start with Foursquare!) and see if you have any unusual file extensions.  Removing those may resolve your problem.

Hello everyone, I'm new here and own a Fascinate now for two weeks. Yesterday I to noticed/encountered the rebooting mtp application when plugging in the cable while the USB settings are set to 'connect to Kies'.

To be short I tried all offered solutions found on this topic on the web and in the end only the unmounting and formatting of the INTERNAL sd has helpt.

I made a backup via Websharing since selecting the 'mass storage' option didn't work for me yesterday. Obviously this is a slow way to make a backup. Try to only back-up what you deem to be imported files.

So the unmounting - formatting and rebooting (mounting) of the INTERNAL cards is the quickest solution and will safe you hours of work!


HOWEVER
Today I had the same rebooting MTP issue again. But since re-installing kies version 1.5.1.10083 I'm able to connect to the pc via 'Mass Storage'
You will see drive F: and drive G: if you at least succeed in connecting via the mass storage option.

I than did 2 things:

1.
I recently made some pictures and also copied some pictures from my pc to the G: drive ( INTERNAL SD) I renamed the pictures to short names so they didn't exceed 16 characters (one of the solutions I read online ).

2.
In the map data I found folders with the names of in my case Touiteur and Beautiful Widgets. Both folders contain a CACHE folder. I deleted the complete touiteur folder and thus also its CACHE folder.

Now I connected my Fascinate to the usb cable again and behold, the rebooting of the MTP has stopped!

Now I'm not technical at all and have struggled with this issue the whole of yesterday ending up formatting my internal SD. And to be honest I don't know for sure what the working solution is in the end but can narrow it down to 2 things you may try if you can connect via the 'mass storage' option:

1. try giving pictures in G:\DCIM\folder name a short name if they are long or try to remove the pictures completely (make backup) just to see if either of this works.

2. Delete the CACHE folders in the APP folder under G:\data and see if this works

Again, I'm unsure what or why I solved it on my Fascinate but give it a try if you have tried everthing else and do not want to format your INTERNAL SD

@smoj

Thank you for providing your feedback on this issue. Now that you confirm that indeed deleting  the folder on the internal SD cards containing the application name and cache file also has solved this issue for you it seems that this must be the easiest fix! I just wish I would have found your feedback earlier but I'm sure there are a lot of folks out there that will be happy to know this!

And with regards to the device not being recognised by Kies, I had this issue before also but it also has been solved without doing a windows system restore.
For me it's now working fine with Kies version 1.5.1.1.003 and Samsung USB Driver For Mobile phone 1.3.450.0 (not the latest driver I'm aware). Try this combination of Kies and driver version and it may work fine. Kies you obtain from the samsung website and just google for the driver.

Thanks again Smoj. I think although still a bit annoying we have the best ( read easiest ) fix for the rebooting issue up till now that will help a lot of Kies users.

# NOTE: this has nothing to do with your PC, your drivers, The OS, KIES, or anything else but your Samsung device and the Android running on it. This is a SAMSUNG / Android problem / Bug. I've tried this on XP, Vista, Windows 7 x32 AND Windows 7 x64, and the Samsung Fascinate i9000 performed the same way on all those no matter what I did with the PC, Programs etc.

SOLUTION:  just format the *internal* SD card and you're OK:

1. Copy all DCIM/Photos to External SD Card or send them by email or back tem up via Bluetooth or use a backup program to back it up to your external SD Card
2. Unmount and remove your external SD Card
3. Unmount and format the internal SD Card
4. install your External SD card again

poof!  Your done!   No apps harmed.

I had the same problem. 
It was working last week. Over the weekend I had downloaded a few apps.
Plugged in the usb today , and yes back to the flashing mtp can't connect bullshit.


I cleaned my cache on my sd card.....

Then I removed soundhound (although I liked that app)

All works fine again. 

Finally got it.  Did some more deleting (had an app that stored all its data in /sdcard - lots (500+) small, html files.

Now I can connect to Kies.  Still no upgrade to Froyo yet, darn!  They said by November
