I have an Android phone from LG, and I want to use it for USB debugging. I followed the following steps:

  1. Enabled usb debugging in developers option on phone.

  2. After connecting to PC, phone shows as "Usb debugging connected". I verified the same by running lsusb on Ubuntu 14.10. It shows the following result:

    Bus 002 Device 003: ID 1004:633e LG Electronics, Inc.
  3. Then I followed steps given in https://developer.android.com, to setup hardware device.

    • Log in as root and create this file: /etc/udev/rules.d/51-android.rules.

    • Use this format to add each vendor to the file:

      SUBSYSTEM=="usb", ATTR{idVendor}=="1004", MODE="0666", GROUP="plugdev"
    • Now execute: chmod a+r /etc/udev/rules.d/51-android.rules

  4. After that I rebooted the computer.

  5. Now when I try to check device list in adb by command ./adb devices, it does not show the device listed.

Can anybody please help? Where am I going wrong?

  • Does it show the USB debug option to be activated in you status bar?

  • I didn't have to do all this. I'm on Arch so it may be a bit different for some reason, though it shouldn't really be. I installed android-tools, enabled USB debugging on my phone and ran"adb devices" and my device showed up. I tehn ran "adb reboot bootloader" and all that stuff worked perfectly. For fastboot however I needed to be root user. This is how easy it is supposed to be in Linux because of inbuilt drivers. However I haven't tried on an LG phone and there may be some device specific steps you've missed. Mar 18, 2021 at 6:03
  • In fact you could try this on a windows VM if all else fails. I needed this for the MI unlock tool when trying to root a MI device. Mar 18, 2021 at 6:03

  • Try running commands as root from your adb folder:

sudo ./adb kill-server; sudo ./adb start-server; sudo ./adb devices


On the device, change USB connection mode from MTP to PTP.

Worked for an LG G Pad 10.1 (V700).
