Note 3 USB connection problem.

I am trying to connect my Note 3 to my computer and it will not mount as a device that is visible under windows. It was taken for service and when it came back it only connects to the PC as an ADB device, but not MTP when it is fully booted. I can flash firmware while in Odin, I can connect in bootloader mode, I just can not make it visible to transfer files from the computer directly to the phone via cable. Under device manager it says 'SAMSUNG Android ADB Interface'. USB debugging changes nothing either. My S3 shows ADB and MTP but the Note does not. I have attempted with multiple cables on 2 computers and get the same result. If anyone has a suggestion of a way to fix this without having to wipe again, I'd love to hear it. Thanks in advance.

ADB show device as offline after sometime

Guys just bought a new phone and started debugging on the phone. I'm facing this issue.
While I'm trying to debug the apps on my device. My device is showing as offline after sometime. Then I again have to Toggle off USB Debugging and switch it on. I even checked adb devices it shows the device as online and then offline after sometime. Anyone facing similar issues or knows the solution please help me with the same.
Thanks

I solved this by changing the usb cable and updating the usb drivers of my phone, give it a try

dont think so.
Hey thanks for the reply. The USB cable is brand new and of very good quality. Also ADB drivers are installed properly. It works once I toggle the USB Debugging in the phone so I dont think it would be related to the data cable.

Maybe the rom if you are using a custom one

The debug bridge will never go "offline" as long as it is connected to the device, and as long as you have USB-debugging "on" in your device and the correct drivers are installed. The point being that ADB isn't the issue, I assume that you are debugging/logging through LogCat , "and that piece of shi* really sucks," if LogCat stops logging or says it is disconnected try to rearm it by manually launching the app you're debugging, or Run the app from your IDE. That will work most of the times, alternatively you can use the old Android logcat which is fully functioning but not as good as LogCat.
If all fails start debugging through ADB in the console.

showing adb device offline :?

Seems you have selected don't ask next time feature. If you can see MTP on pc then USB debugging should be working. Try and And see if your device detected

S7 Edge not recognized

Hello! First, sorry for my bad english. In December after I install Android Nougat with Odin my pc doesn't recognized my phone. I tried different method but no one resolve my problem. I tried to :
1. Install drivers manually
2. Activate USB debugging from developers option
3. Connect my phone to different PC (Win 7/8/10 and Mac)
4. Factory reset
5. Change cable.
At device mannager appear Unknown USB Device and I install Samsung drivers manually.
My phone is not rooted.
PLEASE HELP ME!

does your phone charge when the cable is plugged into your computer ?
Prior to upgrade what type of connection did you have MTP or something else ?

My phone is charging when i plug in computer and is selected mtp connection .

adb mode not work in ng

So I have tried and tried to get adb mode working on my Galaxy s8 with no success. Is there anything special you need to do first to get your computer to see your phone??

Have you enabled usb debugging in developer options?

If the above poster didn't nail the problem then 9/10 times the issue is with either the USB drivers on your machine or a bad USB cable

I ended up getting it running on a different laptop. Worked right away. Seems my original laptop doesn't recognize the Samsung device, even with the drivers
