Are using Mass storage or MTP?
Either one, try the other.

very weird pb.please help

Hy guys,
I was trying the other day to flash a friends Galaxy S stock 2.2 but i couldnt connect the phone to the pc. In the pull down menu, it didnt appeared the dialog to click to go for usb mass storage or anything.
I've selected USb Debugging, clicked in the options for USB Mass Storage, and when i connect the phone to PC and cable, both play the connected sound, but still nothing more. What could be the pb? and how can i solve it?
Pleaaaaase help
And thanks in advance
also to mention. I'm running win 7 on 64bits, drivers installed correctly and my phone has no pb at all when it comes to connect it to the PC.
So....Odin not recognizing, PC not recognizing phone...what to do....?
try different ports or re-install your drivers(kies) take a look on the Themes and Apps section i saw a thread for drivers... try on a different computer....
have tried reinstalling the drivers, also using all the ports available on my pc. still the same pb.:-<
Definately PC issue. Reinstall Kies drivers.

[Q] Something is wrong with connection

PLEASE HELP.
I cannot connect to Kies both via USB and WI-FI. When USB is connected, the phone says "MTP connected" and that's it, does nothing else. Is that normal?
On Kies window when connected via USB, it keeps saying "connecting..." and never connects. I tried troubleshooting it didn't solve the problem. When trying to connect via Kies via WIFI, the Kies window says "No SIM card inserted. Unable to continue communication" (the SIM card is definitely inserted b/c I just made a call)
What should I do?
Please help.
I have tried un-checking and checking the USB debugging function but still not working.
I tried uninstalling and re-installing Kies, doesn't work.
When I try using USB mass storage, it works fine
Kies Air works ok.
PLEASE HELP
Thank you.
Never mind. I figured it out myself. Now my note is running ICS!
Thanks anyways

Got the latest drivers installed? Maybe your usb port broke... check if there maybe is dirt in your usb port. Also if you have the chance, try to use another pc, just in case your pc is the problem. Had the same problem once

connexion usb don't work but "mtp connected"

Hello everyone,
Here the problem, I just acquired a Galaxy note and I can not connect to my Windows 8 PC (or windows 7) . Whether with or without kies.
In the device manager I have "unknown device"
I also tried odin mode and recovery of origin, but no way to install the drivers.
The galaxy shows in the bar notif "mtp connected" ( the smartphone is charging)
It is version 2.3.6. stock not root with kernel: [email protected]#2
did someone have an idea?
thank you in advance for your help.
Sorry for my english, i'm french.
U can set it in Settings > USB
But since u are using GingerBread, ur device might not be able to detect the usb port as more than charging port. This is very unlikely but it can happen..
And do Enable USB Debugging..
i have tried but it doesn't work too
uninstall kies and drivers reboot the pc. then download
http://developer.samsung.com/android/tools-sdks/Samsung-Andorid-USB-Driver-for-Windows
and install it without the phone connected. connect the phone and see what happens.. when you connect the phone, there will be notification of drivers being installed in the system tray of pc. click on it and you will see what is installed and what is failing.
Change ur usb cable to another usb port. This happened to me last time when I tried to flash new rom via odin. Everything is fine but the odin didn't detected it. b4 do that remember to install ur GN driver.
Sent from my GT-N7000 using xda app-developers app
i have tried to reinstall drivers but always the same problem "windows can't install the device...)
i have tried use 3 diferents usb cable too... no result
I would like change the rom (to see if it was the probleme) but it's impossible without root. And the phone don't propose upgrade OTA...
There could be a problem with the usb port itself. You could try to clean it and test again.
i have do this but no result...

Then it could be your mini USB cable. Try another cable.
Edit: Sorry, accidentally misread something. You tried 3 usb cables. My bad.

does device manager see your phone
have you tried different usb ports and cables.
have you installed the HTC drivers
do you have usb debugging enabled in developer options ?

Reboot your phone and computer then try to connect it again. If the same issue, then look at this post and see if it will help. I have also uninstalled the drivers, rebooted the computer and then install the drivers again but not HTC Sync Mgr.

If you have not done it already, try wiggling the mini-usb cable to see if it improves anything. Is the phone charging? It might be a hardware problem, I have read in some other post that it is the motherboard. Sorry, I can not think of anything else.

Yes i try to move the cable in the side of the micro usb, and 5 Or 6 diferents cables, and yes, the phone only charge.
Its very strange because I bought the phone used and only works one day and the second day lost the connection to pc when in try to unlock the bootloader, the first time no connected and suddenly work, I can only unlock the bootloader and stop working.

Try to clean the phone's contacts with a little rubbing alcohol and/or compressed air. There maybe lint or dirt on the contacts preventing a good connection.

Unfortunately that link does not work anymore. What was on it?
Asking because I got an m7 here where USB works just fine and reliably in both fastboot and recovery. But when the system (any ROM, tried more than 10 now), there's only charging. No MTP, no nothing.
Laptop's `dmesg` says:
Code:
[150266.816544] usb 2-1.5: new high-speed USB device number 16 using ehci-pci
