Perform a Factory Reset

  4. Here, use Volume Up/Down keys to navigate to the wipe data/factory reset option.
  5. Use the Power key to select the option.
  6. You will be asked to confirm. Again use Volume Up/Down keys to navigate and Power to select Yes- delete all user data.
  7. Then use the Power key to select Reboot system now.

After resetting the device, see if the connection establishes. Factory reset was the last resort to check the software, if the issue is still there, that means the issue is related to hardware.
