"adb devices" command won't detect my 4.4 Android phone [closed]

I've been having a issue trying to get the adb devices command to pick up my LG TRANSPYRE™ (VS810PP) phone. Keep in mind the command does in fact work. So it's not an issue with adb, more with the drivers.

After taking a look from this post I found online, I did the steps properly (three times, just to be sure).

So I basically did this:

1. Created a file: /etc/udev/rules.d/70-android.rules.
2. Wrote SUBSYSTEM=="usb", ATTR{idVendor}=="1004", MODE="0666" to the file.
3. Assigned proper permissions via sudo chmod a+rx /etc/udev/rules.d/70-android.rules
4. Rebooted my computer.
5. Restarted udev.

And the results:

$ adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached 

(But nothing came after that)

But I didn't give up just yet. I read from another post here on Ask Ubuntu, I tried again.

Again, the process:

1. Created a file: /etc/udev/rules.d/51-android.rules
2. Wrote SUBSYSTEMS=="usb", ATTR{idProduct}=="1004", MODE="0666" to the file
3. Gave proper permissions sudo chmod a+rx /etc/udev/rules.d/51-android.rules
4. Rebooted the 'pooter.
5. Restarted udev.

The output is the same as above, still not fixed...

I've very new to android, but my best guess is that I'm using some sort of out-dated method, because those posts are at either 2 or more years old. So there is probably a new method now.

Edit:

Set mode from MTP to PTP. I had the same problem.

MTP means Media Transfer Protocol. PTP means Picture Transfer Protocol, which means that the phone appears to the computer as a digital camera.

To set the mode: Settings > Developer Options > scroll down to Select USB Configuration, tap this and select PTP or just click at notification in status bar and select PTP.

This happens to me sometimes with certain devices. Here's what I find works:

1. Find the Vendor ID: You can do this by typing lsusb. My output is something like this:

   Bus 002 Device 097: ID abc1:1234 Fictional Company, Ltd. 
   

   In this case, abc1 is the Vendor ID.

2. Create an adb_usb.ini file: Run the following

   echo "0x<your device's Vendor ID>" > ~/.android/adb_usb.ini
   

3. Restart adb

   adb kill-server
   adb start-server
   

Since doing that, my devices have all shown up in adb devices.
