Answer 1

It's not worth it. Use something like SSHDriod and then connect over ssh. There are also FTP servers and even Driod NAS that gives cifs access. MTP does not work well, and likely will continue to not work well for the near future.

If you really want to get mtp working then make sure you set your Nexus to NEVER lock the screen or power off the screen. Locking the screen with "lock" the MTP protocal as well, causing all manor of data loss and connection issues. Powering off the screen in the stock kernel (might even be hardware) will turn the CPU down as much as it can and enable tons of other strong power saving features, that will result in horrid (but still working) transfers.

Answer 2

MTP is a Microsoft technology and is not officially supported on Linux. I've tried Mtp-Tools many times too, without success. If you consider an alternate method though, I've two recommendations:

• Using FTP, instantiating an FTP server on your tablet via Software Data Cable or other software.
• Using adb, which is a tool of Android SDK, to push and pull files from tablets and phones, through USB Debug Mode. To use adb, get it working and run adb push /source/path /destination/path. Better explanation : http://log.amitshah.net/2012/05/using-adb-to-copy-files-to-from-your-android-device/

Answer 3

If your computer and Nexus are on the same wifi network, you can use an app called AirDroid. It's free

https://play.google.com/store/apps/details?id=com.sand.airdroid&feature=nav_result#?t=W251bGwsMSwxLDMsImNvbS5zYW5kLmFpcmRyb2lkIl0.

1. Open app on device.

2. Go to web.airdroid.com on computer web browser.

3. Enter passcode generated on device into the web app.

4. Automatically connects. You can transfer files, view contacts and many other things. It's great. I use it all the time.

I hope this helps.

Answer 4

This post is similar to the first one you linked, but the steps are a bit different. It might help to give it a try.

The steps are summarized below for convenience.

Disclaimer

I have not personally tried the following steps. I cannot guarantee their safety or usefulness. Use at your own risk.

Mounting

1. Install the relevant packages:

   sudo apt-get install mtp-tools mtpfs
   

2. Create a new udev rule using the following command (requires password):

   gksu gedit /etc/udev/rules.d/51-android.rules
   

3. Here we will deviate from the posted steps a little based on a comment from the linked post. In a terminal, run lsusb with your Nexus 7 connected via USB. You should see output like the following:

   Bus 001 Device 010: ID 18d1:4e41 Google Inc.
   

   Keep the two colon-separated values after the ID part in mind for the next step. They are what you should set ATTR{idVendor} and ATTR{idProduct} to, respectively.

4. Type the following text into the file, all in a single line (numerical values used are those from the original posted steps):

   SUBSYSTEM=="usb", ATTR{idVendor}=="04e8", ATTR{idProduct}=="6860", MODE="0666", OWNER="your-username-in-ubuntu"
   

   As an example, using my username and the values from the comment, the line I would enter would be:

   SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e41", MODE="0666", OWNER="christopher"
   

5. Create a mount point for your Nexus 7:

   sudo service udev restart
   sudo mkdir /media/Nexus7
   sudo chmod a+rwx /media/Nexus7
   

6. If your Nexus 7 is not already plugged in, do so now. Then run the following command on Ubuntu in order to access it:

   sudo mtpfs -o allow_other /media/Nexus7
   

   This should allow you to use Nautilus in order to browse your Nexus 7 and transfer files.

Unmounting

When you are finished with whatever you are transferring, run the following command to unmount your Nexus 7 before unplugging it:

sudo umount mtpfs

---

And in case that didn't work...

...you can take a look at a supposedly more reliable way to connect here.

Answer 5

I would recommend 'Go-mtpfs'. There are 2 way of use this program that i should explain.

First install the program using the folowing commands:

sudo add-apt-repository ppa:webupd8team/unstable
sudo apt-get update
sudo apt-get install go-mtpfs

Using the terminal

If u want to use the program using the terminal or if u simply hate unity.

1. Mount You mtp device
   For mounting your device probably do the following command.

   go-mtpfs /media/MyAndroid
   
   leave your terminal open so long you use your device.

2. For unmounting your mtp device
   Close the terminal or do ctr+c for terminate the program.
   fusermount -u /media/MyAndroid

Using the custom Unity Launcher

1. First install the launcher:

   sudo apt-get install go-mtpfs-unity

2. Press the ubuntu button on the unity launcher. Search for "Mount Android Device". And drag the icon to the unity bar.

3. Than simply right-click the icon and you should get this.

Enjoy your android device that now works perfectly on ubuntu :D.

Answer 6

I followed the steps mentioned on the post u link, and worked fine for me, but i mounted using sudo command before the mount.. another thing i pluged the device before doing all the steps. and now is working fine.. Also check that ur device have enable the option USB computer connection, there i selected Media device (MTP). That's all i have done.. hope u can make it work soon. Regards

Answer 7

Try using gmtp instead of mtpfs.

gmtp provides a friendly UI and I have used it reliably for years.

Answer 8

Got it working with my Nexus 4 by installing the newest version of libmtp from launchpad. The version for Raring Ringtail works fine on my 12.04 system. The instructions stay the same as in your tutorial.

Edit: Although it works, it's painfully slow... I'm right now copying with 7 kb/s

Edit2: Nvm, it got up to 350 kb/s, which is acceptable I presume.

Answer 9

Is your Android device password protected and locked? I found I was getting the error:

Transport endpoint is not connected

because I hadn't entered the password. Once I authenticated on the device, I could connect.

Makes complete sense when you think about it. You shouldn't be able to just grab a device you don't have a password for and connect to it via computer.
