lg g3 bootlooping after upgrading

I am using Lg G3 D855 international version(32gb).I updated it from android 5.0 lollipop to 6.0 marshmallow manually by using .kdz file through lg flash tool and my update completes 100% without any error and after my update I factory reset my phone, after first factory reset now my phone is rebooting again and again(bootlooping)….

(First problem and reason for update is my WiFi and Bluetooth not working and it tries to turning on...)

What can I do to solve this?

I need anyone’s help to solve all my problems
