I just want to access the files on my Verizon LG G3 phone from my Linux PC.

I have adb installed and I followed this ArchLinux tutorial but adb devices outputs the following:

[grease-lightning]/home/lucas$ adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached 

I also followed this xda-developers tutorial but the MTP tool does not seem to detect my device properly.

I have usb debug on, and MTP mode on, (via Settings > Storage > usb/pc connection > "MTP" (default was PTP) on my Android phone).

I also tried running the commands mtp-detect with this output and mtp-connect with this output, but I cannot seem to access the file system. Most notably, it seems that the vender and product id are not detected, as quoted here from the mtp-detect output:

Device 0 (VID=1004 and PID=627f) is UNKNOWN.
Please report this VID/PID and the device model to the libmtp development team
   Found 1 device(s):
   1004:627f @ bus 3, dev 25

As instructed in the xda tutorial, here are the contents of my udev file:

[my-pc]/home/lucas$ cat /etc/udev/rules.d/51-android.rules
SUBSYSTEM=="usb",ATTR{idVendor}=="1004",ATTR{Product}=="627f",MODE="0666"

and here is the lsusb info for clarification:

[grease-lightning]/home/lucas$ lsusb | grep LG
Bus 003 Device 039: ID 1004:627f LG Electronics, Inc.

So, after trying these tutorials using the mtp and adb approaches, how can I connect to the files/media on my Android phone? Any suggestions?

I am using ArchLinux if that matters, and I would prefer a simple CLI approach to accessing the files on my phone.

I had the same problem with my nexus 5 on ubuntu. It was a problem of permissions; the device file was root for some reason.

What does this yield?

ls -l /dev/bus/usb/003/039

If it's owned by group root and owner root then an elegant solution would be to add the group entry plugdev in your udev, which you should already be a member of

SUBSYSTEM=="usb",ATTR{idVendor}=="1004",ATTR{Product}=="627f",GROUP="plugdev",MODE="0666"

  • Thanks for the help, and this may be the problem, but Arch does not have a plugdev group. I tried creating a similar udev group with the contents SUBSYSTEM=="usb",ATTR{idVendor}=="1004",ATTR{Product}=="627f",TAG+='uaccess', but that didn't work either. Any suggestions would be helpful. – modulitos Jun 13 '15 at 1:29

I think I resolved this by using the jmtpfs tool. I ran the commands jmtp -l, which output this:

Device 0 (VID=1004 and PID=627f) is UNKNOWN.
Please report this VID/PID and the device model to the libmtp development team
Available devices (busLocation, devNum, productId, vendorId, product, vendor):
3, 48, 0x627f, 0x1004, UNKNOWN, UNKNOWN

Although it didn't recognize my device, I was still able to mount it with jmtpfs ~/temp/lucas-android then access the filesystem as usual.

BTW, I filed a request to add my device with libmtp on sourceforge
