phone-to-computer data transfer from Samsung Convoy 3 with Mint 13


I was recently given a Samsung Convoy 3 phone as an insurance replacement. One of the phone's features is that you are supposed to be able to transfer data directly from the phone to your computer using a USB cable, but the phone's data transfer program (Mass Storage) has been hanging at the step where it contacts the computer. I am running Linux Mint 13, and I've determined that the operating system recognizes the phone when I plug it in, but it doesn't mount automatically. Verizon and Samsung have not been helpful.

Today I figured out how to mount and unmount the phone manually using mtpfs, but I wasn't sure what program to assign to open it, and the one I chose didn't work. Now I can't figure out how to change the program assignment -- no "open with" option comes up when I right-click on the icon on my desktop -- and I'm also not sure what program to use.

I'm willing to do the whole data transfer via command line if someone can walk me through it. I'm not very experienced with command-line prompts yet, but I've loved the ones I've learned so far.

Thanks!

Once the phone is mounted via mtpfs it appears just like an external drive to the system. You should be able view its contents via a file browser by navigating to its mount point i.e. Nautilus or the command line by use cd /mount/point. Be sure to close the file browser or move to another directory if in a terminal window prior to unmounting the phone.

Depending on what software version is running mass storage may only be available if you have a memory card installed or possibly this function was removed with later releases.

Do you have 13 LTS?

From the phone's menu, go to Settings -> USB mode. Select USB Mass Storage, to enable access to the phone's memory and any additional memory card.

When you plug the phone into the usb port, it should mount automatically into either /media or /mnt (may also create a subfolder for Samsung).

Then use your file manager to view/move/delete etc.

If you want to transfer files between a phone and a PC, install Airdroid from the Google store. Run it on the phone, and you can access the phone through your browser. It's quicker and easier than using a USB cable.

@michaelk: Thank you. When I mounted the phone again manually and changed directories to the phone directory, I got this message:

bash: cd: /media/phone: Transport endpoint is not connected

The phone is connected to the hard drive by a USB cable, and it's turned on. It has a 16-GB SD card inserted.

Sorry -- yes, I am running Mint 13 Maya/Mate 64-bit.

@bigrigdriver: Thank you. I did try to do it this way, but it didn't work. The program gets to the point where it tries to connect to the computer, and it hangs there for as long as I care to leave the phone connected to the computer. I think the longest I left it connected was 4 hours. I've tried rebooting the computer and removing and reinserting the phone's battery, but it didn't help. Samsung doesn't have any support staff who are familiar with Linux, and neither really does Verizon. I did get one nice Verizon guy who had used Linux in the distant past, and he sent me several links to diagnostics, which is how I was able to find out that my computer was recognizing the phone when I plugged it in but that it wasn't mounting properly. I found some other posts from Linux-users who had trouble with data transfer with this phone, so I'm guessing it's a glitch in the program, but I don't really know.

@sgosnell: Thanks for the suggestion. I just tried to install Airdroid, but it isn't available on my phone. If it's an Android program, as I assume from the name, that could be why -- my phone isn't an Android phone. I couldn't afford the cheapest Android phone plan.

Most linx systems are moving from "Mass Storage" mode to MTP you may need to change usb settings of phone to MTP to access.
I know this because I have a Debian Wheezy macine that uses "Mass Storage" mode, but my Jessie installation will only use MTP.

@Eddy1: Thanks very much for that suggestion. I haven't tried it yet. Can you tell me anything about how to do it? The phone came set up with Mass Storage, and the manual is pretty minimal. Thanks.

You can only change the settings when the phone is connected.

Not sure this helps much...
http://www.verizonwireless.com/suppo...se.html/83294/

The output of the dmesg command might provide error messages when it hangs.

Not sure linux is moving or just the industry maybe influenced by Microsoft. Support has be added i.e. gvfs and mtpfs so MTP looks the same a mass storage device.

@michaelk: Thanks for the link. I tried to follow the Verizon instructions at the outset, but unfortunately the USB Mass Storage program is hanging at the step where it contacts the computer.

I ran dmesg, and it appears that my computer is recognizing the phone. I can't include the full output, because it's too long, but here are the pertinent parts:

[360954.839842] scsi 10:0:0:0: Direct-Access SAMSUNG MMC Storage 2.31 PQ: 0 ANSI: 2

[398023.172585] scsi 12:0:0:2: CD-ROM SAMSUNG CD-ROM 1.00 PQ: 0 ANSI: 2

I ran mount to see what was mounted. Here is the output. Note: the phone does not mount automatically, and I haven't manually mounted it yet.

/dev/sdf1 on /media/Elements type fuseblk (rw,nosuid,nodev,allow_other,default_permissions,blksize=4096)

Here is the output of mount after I've manually mounted the phone. The last line of the output confirms that the phone is mounted.

/dev/sda1 on / type ext4 (rw,errors=remount-ro)

/dev/sr0 on /media/050530_1231 type iso9660 (ro,nosuid,nodev,uid=1000,gid=1000,iocharset=utf8,mode=0400,dmode=0500,uhelper=udisks)

mtpfs on /media/phone type fuse.mtpfs (rw,nosuid,nodev,allow_other)

As before, if I now try to run USB Mass Storage, the program hangs at the step where it contacts the computer. I've hunted around in Settings, but I haven't been able to figure out how to switch the USB setting from Mass Storage to MTP. Do you know anything about this? One thing I've wondered is whether the phone might need to be rooted, but I haven't been able to find instructions for this for a non-Android phone (the Convoy 3 is a non-Android device).

@michaelk: One other thing I forgot -- if I try to open the file (which I named "phone") by double-clicking on it on the desktop, I get an error message saying "Could not open "phone" | the file doesn't exist".

Once you plug the phone/tablet into computer there should be a usb icon on the top left corner of the screen drag it down & there should be options on how you want it to connect to computer.

@EDDY1: No icon appears on my screen when I plug in the phone. Is there a way to change the USB assignment via the command line?
