LG Device Not Listed in ADB Devices

Question

This is similar to the question already asked here:

Trouble connecting to LG phone with adb (Mac OS X 10.7.5)

But it does not seem to be resolved and I have a few additional details. I am attempting to connect a Verizon LG Optimus Exceed 2 to install an apk and debug, but it will not appear in the list when checking adb devices or running the device monitor. I have tried on both my Mac and Linux systems and the result is the same.

Developer options and USB debugging are enabled, and I have a Samsung Galaxy S3 that works perfectly fine running the same version of the OS (4.4.2). On Linux I created a udev rules file, but unsurprisingly this did not resolve the issue since it doesn't appear as a permissions issue, it just doesn't seem to find the device at all. It does however appear as an attached device in the file system, labeled "LGE Android Phone," and I can view its internal storage.

Any suggestions how to get adb to recognize the phone?

Answer 1

Changing USB mode from MTP to any other mode works, which is because it reports different device id that can be supported by google's android adb driver. If you want to have adb support for MTP mode, then LG's official driver should be installed.

Answer 2

The problem is with the "do you trust this computer" dialog not being shown.

On LG Spirit 4G, the solution is as follows:

• Ensure the developer menu is enabled (through About phone -> Software info -> keep tapping Builder number)
• Ensure USB debugging is enabled in the developer menu
• Go to Settings -> Tethering & networks -> switch on USB tethering

This will finally trigger the "do you trust this computer" dialog and enable USB debugging.

Addendum: After your device is disconnected, the issue might appear again because USB tethering is automatically disabled.

Answer 3

I am using an LG Wing. To get this to work I had to change the setting of what the USB connection was for from File Transfer to Photo Transfer to get it to start showing up in the adb devices list.

Answer 4

In my case, I could not find the Tethering option @Ken Van Hoeylandt mentions (language issue most likely), so rather than change the phone language, I noticed that when switching from File transfer to Charging in the USB options (located in Settings or in the drop-down menu), the prompt to "trust this computer" came up. Device used is an LG K40.

Answer 5

Well, not sure if the OP is still looking for the answer. I happen to run into the same situation with Mac OS Yosemite and LG Optimus Exceed 2.

I did add the vendor ID to dab_usb.ini file, however, it still doesn't work. I also installed LG driver downloaded from LG website, still no good.

Finally, I switch the PC connection to "Internet connection" > ethernet. Then, it finally shows up in adb devices !!!

Answer 6

This is valid for any device that is not in the ID Vendor in Android Studio or Eclipse and you want to connect to debugging in OS X:

1) Go to Terminal and then:

cd ~

cd ./.android

2) Edit the adb_usb.ini You should use vim instead of textedit.

vim adb_usb.ini

Some text to edit appears:

# ANDROID 3RD PARTY USB VENDOR ID LIST -- DO NOT EDIT.
# USE 'android update adb' TO GENERATE.
# 1 USB VENDOR ID PER LINE.

¡¡Insert here the line with the ID Vendor!! The ID Vendor is in About this Mac - system information - USB (have the device to be connected)

3) Go to the path:

cd <where you have the sdk, be careful if you are using Eclipse or Android Studio>/platform-tools

Then, export to the bash:

export PATH="/Applications/Android Studio.app/sdk/platform-tools":$PATH

Then:

sudo adb kill-server

sudo adb start-server

adb devices

4) Run Android Studio, and in the DDMS, your device is detected. Then allow permissions in the device.

5) Start debugging, enjoy.
