After Android 6.0 update my phone does not show up when connected to computer - Nexus 6 Q&A, Help & Troubleshooting

I have been facing a strange problem since I updated my Nexus 6 to Android Marshmallow. When ever I am plugging the phone to my computer (Running Windows 7) using the usb cable, I am not being able to tranfer any files. Its showing a message which says that "The device has either stopped responding or has been disconnected". Any help on this will be really appreciated

adb driver already installed?

Yes. It shows that all drivers are installed correctly....In fact, the device also shows under device manager. Its just that no tranfer is possible between the phone and the computer

did you bring down notifications and change connection type to MTP?

In Marshmallow your connection to PC is in Charging Mode by default, you should bring down notifications select connection mode and change connection type to MTP(Media Transfer Protocol).

[SOLVED] Galaxy S Advance stops being recognized by Windows 7 after a while

I have this strange problem:
when I connect my Samsung Galaxy S Advance to my PC, the phone is recognized and I can start downloading my pictures, but, after a while, the download is interrupted and phone is not recognized any more...
Symptoms:
- Phone detected at first time is not detected any more after a while.
- After detection failure, if I try to browse my phone content, either in phone or SD card memory, Windows Explorer freezes.
Tried solutions:
- I've tried disabling and enabling all Developer Options on my phone, but the problem persists.
- Also, I've noticed that, while my phone is connected and recognized by Windows, the command
Code:
adb devices
returns an empty list of devices.
These are my system characteristics:
Phone specs
- Model code: GT-I9070
- Android Version: 4.1.2 (Jelly Bean)
- Baseband: I9070XXLQE (Germany)
- Kernel: 3.0.31-1122398 [email protected] #2 SMP PREEMPT Tue Apr 9 14:55:54 KST 2013
- Version build: JZO54K.I9070XXLQE
- Root: NO
- SD Card: 8GB working and recognized
PC specs
- OS: Windows 7 64-bit

What can I do?
Thank you very much!
Try reinstall the Kies driver...

i'm not an expert but i would try disabling samsung kies, reinstalling samsung drivers, then plugging cable in different usb port, also could be faulty cable, dirty connectors @ phone, firewall... :fingers-crossed:

I have the same problem, the connection is lost when you turn off the screen.
Now I can't even connect the phone to the PC, it is not recognized...
See this thread...
Help please.
If you have wi-fi use samba filesharing.
The problem is with your usb cable-usb port-windows
Control panel -device manager -print screen with universal serial bus controllers

Yes, the problem must be with my USB cable, port or Windows.

I've tried to change USB port and the automatic driver installation gave the attached result: a partial error... still no recognition as MTP USB device
I cannot see the phone content in Windows Explorer... I don't know what I can do with the successfully installed device "SAMSUNG Android ADB Interface"...
I attach some more screen-shots of the connected and partially recognized Android device properties...
It seems that the modem function of the phone has been recognized by Windows, but I just need the USB storage feature!

Thank You for your reply in that other topic. Now to this matter.
1. What option did you choose under lock screen? Swipe or None?
2. Even I have faced the problem and the solution i found was simple. This happens when our phone goes into deep sleep and to bring the files back you just need to unlock the phone. Just press the unlock or homescreen button and windows will start recognising the phone again.

Hi,
1. None.
2. The screen is always on, Windows loses the connection without apparent reason in the first minute or so of connection. Now is even worse, I've just connected the device and I can't explore the phone folders because Windows just stopped recognizing the phone...
This is what I see in Windows Explorer after connecting the phone: Windows seems to lose connection to it, failing to find files and folders...

Need help trying to unlock bootloader on HTC One

So last night I tried unlocking my bootloader so I could root my HTC One, but I've had one issue. Whenever I get to the part where you make the back up of my apps I get the following message "adb: unable to connect for backup". My phone is conncected, and I have USB debugging enabled. I also checked the device status and it keeps reporting it as offline. I don't quite know what to do, if anyone can help it'll be appreciated.
First off, I barely know anything with regards to phones as I still learning. However, last night had a similar issue and ended up having to use cmd prompt to navigate to adb and then used it to see the device.

New security enhancements in android 4.2.2 builds (and above) require the end user to explicitly grant adb access to any connecting computers before that connecting machine can successfully issue any adb commands to your device. When you connect a 4.2.2 (and above) android device to your machine (with USB debugging enabled) for the first time, you should be prompted with a confirmation message to allow or disallow USB debugging. This message will display your computers unique RSA key fingerprint and provide you a checkbox to “Always allow from this computer”. Check this box and select ‘OK’. Your device should no longer be listed as ‘offline’
If you don’t see this prompt then you should try the following:
With your device connected via usb and the toolkit running, toggle USB debugging off/on in Settings > ‘Developer Options’ and see if the prompt comes up
Also try unplugging and re-plugging the usb connection.

You have to help us with a little more info -- ADB and Fastboot just *have* to work or you'll get nowhere:
1) What OS are you using? Version included;
2) Plug in your phone, open a command window in the appropriate place and type: adb devices
Tell us the output.
If you don't get a device listed, either your drivers are bogus on your machine and need to reload, or you're not getting USB debugging setup correctly (not sure how you miss that, so I'd think the former).

I know you don't want to read this, but you'll need to read all about Macs and this issue. A quick Google on "adb unable to connect for backup mac" brings up all sorts of folks fighting exactly what you are. I don't have a Mac -- use Linux almost exclusively, but it all appears related to either usb debugging, or a connection timeout setting.

[SOLVED] Windows 7 can't recognize Samsung Galaxy S Advance GT-I9070

Hi everybody,
I have a 64-bit PC with Windows 7 Ultimate Service Pack 1 and a Samsung Galaxy S Advance GT-I9070 with Android 4.1.2.
I can't install a driver in order to make Windows recognize correctly the phone when I connect it via USB cable.
I've installed and uninstalled Samsung Kies many times with no results. I've also tried some Samsung driver from Windows Update with no success...
When I connect the phone, it is recognized as a MTP Device and the driver installation starts, but always ends with an error, as shown in the attached screen-shot image.
What can I do?
Thank you very very much.
Note: in another PC with WinXP I have no problems.
Firstly make sure phone can run MTP (make sure if you delete MTP releated stuff in system you won't able connect it. Re-flash with Odin) Now if you don't have problem with phone then uninstall drivers & KIES from Windows. Don't just do a uninstall clear temp files, dll files, registry entries (you can use CCleaner) then install THIS DRIVERS.

Hello, thank you for your answer.
How can I make sure my phone can run MTP?
For the complete uninstall, is it enough to run CCleaner, uninstall Kies and then perform the Registry Cleaner in CCleaner?

Did you root phone ? or installed a ROM or you just using it stock ?
I noticed something too; if you any have PIN or Password you have to unlock phone otherwise MTP not works. Unlock it and try too.
CCleaner will *probably* be enough but if you want to make sure go to regedit.exe and go to;
Code:
HKEY_CURRENT_USER/Software/
Then delete KIES & USB Driver stuff (don't delete system USB configs & drivers just Samsung's softwares )
EDIT: In start menu click to RUN (or whatever I don't now it's name in English, you're entering a text) Then write
Code:
%AppData%
Then delete KIES & Samsung folders and files.
I've just Updated the phone firmware from Android 2.3.6 to 4.1.2 with Samsung Kies on my WinXP PC.
I've deleted all Samsung Kies registry entries.
Now I'm going to install the driver you suggested...
Let me see results...

This may be a bit silly but is important to ask.
Was your PC connected connected to the internet while installing the drivers??
Did you unplug your phone while the drivers were being installed??

I've just tried to reboot the phone before connecting it to the PC, but I get the same error (see attachments).
Last year I managed to connect the phone to this PC, but, in any case the connection got interrupted after a while (see this thread).
I don't know what to do...
I had the same problem when i formatted my PC 2 days ago. I did some trial and error and it worked.
1. Dont use any USB Hub if you are using.
2. Remove the Pattern lock or any password security etc. Go to lock screen and select 'None'. (I dont know why but windows doesn't recognise if the device is locked)
3. Have Kies installed. Even new version worked for me. I used 2.5.13043_14
4.Connect your device with the USB cable (Should have MTP option selected which is by default)
5. Windows automatically recognises now and installs the necessary files.
P.S:- Remove the security pattern, etc. It really works.
If worked then pls reply.
Hello,
I've disable any screen lock on my phone and I've connected the USB cable to another USB port (a 3.0 USB port) and Windows magically recognized correctly the device! (no Kies installed, only drivers)
Anyway, after some minutes of usage (cut-paste of files). Windows stopped recognizing the device...
If I disconnect the phone and then connect it back, Windows still recognizes it, but I have few minutes until the device stops being recognized and no file on it can be read...
See attached pictures

This is how my PC recognizes my phone. The driver seems to be old, but I've configured Windows for downloading drivers automatically and that is all it can do.
Today, th PC did not recognized the phone at once. Then I unmounted and mounted back the MicroSD card and the PC recognized it.
But, after few seconds of folder browsing, the PC lost the connection. I'm thinking that the problem is the SD card.
Solved!
Solved!
It was the USB cable.
I replaced it with an original one and now it works.
Thank you everybody for your effort!

Why does my computer no longer recognize my phone after doing marshmallow update?

I have two Nexus 6s, one completely stock and one that I just upgraded to Marshmallow. I downloaded sdk and minimal adb and fastboot today in order to install marshmallow. I just plugged in my completely stock unmodified Nexus 6 into my computer to get my photos off my stock Nexus before I send it back to amazon and although the phone charges, nothing pops up for it being a storage device, I switched it between MTP and PTP on the phone but it does nothing, the phone does not show up, same goes for the Nexus 6 that has marshmallow on it, also switched that to MTP. My computer detects the phone because it allows me to eject it from usb but that is about it. Anything else I can try? trying to get pics off the old Nexus before I send it back.

I deleted the adb driver and that fixed the issue but that can't be the correct way because I think it would be pointless to have to install and delete the adb driver each time I want to use it?

I honestly don't know. I've always had mixed results. Sometimes it would work automatically, sometimes I'd have to manually install the google drivers when the phone is in the bootloader.
Had the same "problem", to fix it and for windows to show the contents of the phone, you just need to pull down the top drawer and select mtp file transfer from the USB options. It is set for " charge only" as default. Try it out!

Exactly: it is not a problem, but just a new way to manage USB connections. You just have to pull down the status bar and choose one of the USB options for your Nexus 6
lol you guys aren't understanding, I did that and it did not fix the issue. The phone was still not recognized as a storage device. I also tried a Nexus 6 that was on 5.1.1 which does not have the charging only option in the drawer and it also was not recognized but once I deleted the adb driver from my computer, my computer saw both as storage devices when I put them into MTP mode
Go into developer settings
Make sure checked Debugging on
Then Scroll down
Look for MTP CHange it to something else in the settings
then back MTP Your computer will then see it it bug in 6.0

[Q] cant connect to pc in linux or windows

hi folks!
I recently bought a sm-t713 and i can't get my pc to recognize it in linux or windows.. i want to root and unlock the bootloader but odin cant even see it.. and its not an issue with not having debugging on. thats all turned on. Please advise. thanks!
Nobody knows why? I have oem unlock "on"
debugging "on"
But I cant get my comp to see the device..Have Samsung drivers installed. Still no luck.
How can I fix this? all it does is charge when I hook it to pc but can't transfer files.
sorry double post
Same issue here. I've had no luck sorting it out.

USB Debugging and MTP use different drivers and are different protocols.
Open a command prompt in windows then type:
adb devices
You should get a response with a serial number if USB debugging is working.
If so then it's likely an MTP driver problem or MTP isn't enabled.
In developer options under USB configuration, ensure MTP is enabled.
If so check the device is detected as an MTP device in windows device manager.

What the USB configuration is set to is actually moot. When the device is plugged in to a PC the tablet will bring up a notification stating what mode the USB port is in and also provide the option to change that to MTP mode (Transfer files), provided the drivers are correctly installed and all is in working order. By changing USB configuration to MTP the tablet shows up immediately on the PC but you still have to switch to "Transfer file" mode before you can move files between devices. Either way the results are the same and it takes the same number of steps. I always leave my USB configuration in "System Default" and I have never had any issues.

Thanks for helping! under device manager the tablet is showing as a mass storage controller not an mtp device. Even though in the tablet itself I have it set to mtp under developer options.
When I do the command "adb devices" I get this message
C:\Users\Brian\Downloads\platform-tools_r28.0.0-windows\platform-tools>adb devices
List of devices attached
nothings there
Also I was reading this is happening because of the newest stock update from Samsung.. is that true?

No response from the adb command suggests you don't have the correct adb drivers installed or the device isn't being detected at all.
Have you installed the ADB drivers?
I would try a different cable first. Is Windows device manager detecting the device if it's plugged in/unplugged?

Still having trouble here, too.
After flashing a ROM and attempting to install what was probably the wrong Gapps version, I'm now getting a boot loop into TWRP, and the device is still not recognized. I can boot into 'Download Mode', but the device is still not being seen by my PC. I have tried multiple times to install the USB drivers, but Odin 3.12.3 is still not seeing the tablet.
Much as I hate installing hokey, bloated software, would KIES be helpful here?
So, all is not lost (yet) - I can still access TWRP, but I'm not sure where to go from here.
Thanks in advance for any ideas you have.

Considering download mode is totally OS independent and neither uses adb nor mtp drivers it seems the issue is either incorrectly installed usb drivers or faulty cable, device or port issues.
Boot to Download mode, open device manager then plug in the usb cable.
Windows should detect the device as a USB composite device.
If there is no detection then there is a communication issue between device and PC which could be any one of the afore mentioned reasons.
No matter what windows should show some sort of detection as soon as the device is plugged in.
No detection means no matter what drivers are installed its not going to work.
It's probably worth uninstalling the usb ports then rebooting.
Then trying again.

Well, I'll be dipped in $hit.
What's the probability that one guy could have three dodgy USB cables? Used one, wiggled it around and the PC recognized the device. Looks like I'm in for a quick trip to WallyWorld. Thanks!

No response from the adb command suggests you don't have the correct adb drivers installed or the device isn't being detected at all.
Have you installed the ADB drivers?
I would try a different cable first. Is Windows device manager detecting the device if it's plugged in/unplugged?

yeah, windows device manager detects it as a mass storage controller. I installed the driver from samsung site. Cant be the cord cause it works with the phone. Even linux mint wont pick it up either. Any ideas? Thanks again for helping this is driving me nuts!

Are you able to connect to the device in TWRP, either ADB or MTP?

Are you certain this is a genuine Samsung and not a copy?
Can you post the build details from the app Phone Info.
