While using the command adb root

the output I obtained is

adb: unable to connect for root: insufficient permissions for device: verify udev rules. See [http://developer.android.com/tools/device.html] for more information.

Also tried to get help from this Question but the problem is same.

after this command adb devices -l it gives the following output

List of devices attached 9f3a96d5 no permissions (verify udev rules); see [http://developer.android.com/tools/device.html] usb:1-1

and after giving command lsusb

it gives the output

Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 002: ID 1a2c:0e24 China Resource Semico Co., Ltd Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 003: ID 0781:5567 SanDisk Corp. Cruzer Blade Bus 001 Device 091: ID 05c6:9091 Qualcomm, Inc. Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 002: ID 046d:c018 Logitech, Inc. Optical Wheel Mouse Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

So, how can I get permissions to make changes(root,flashing custom roms, etc.) I'm using Linux Mint 19 in my PC and Android 6.0.1

This is most likely an issue with your user's permissions or udev rules under linux.

In order for adb to work properly, your user needs to be added to the following group: plugdev

If that doesn't work I assume there's an error in your udev rules, or you need to add them:

$ sudo nano /etc/udev/rules.d/51-android.rules - Put the following into the file:

# My android phone SUBSYSTEM=="usb",ATTR{idVendor}=="05c6",MODE="0660",GROUP="adbusers" SUBSYSTEM=="usb",ATTR{idVendor}=="05c6",ATTR{idProduct}=="9091",SYMLINK+="android_adb" SUBSYSTEM=="usb",ATTR{idVendor}=="05c6",ATTR{idProduct}=="9091",SYMLINK+="android_fastboot"

This is me assuming Qualcomm, Inc. is your phone. I might be wrong on that. Simply replace 05c6 with the vendor-id and 9091 with the product-id you get from lsusb using your phone's values.

After that run $ sudo udevadm control --reload-rules and re-connect the phone to the pc.
