How to unbrick my Nexus 5X which keeps on bootlooping?

Yesterday, my Nexus 5X started bootlooping. I have tried every possible method to unbrick my device. I also used the nexus tool kit to flash the latest android, unfortunately it didn't work. When I switch on the device, it shows the error message "Your device software can't be check for corruption. Please lock the bootloader" and then the google logo comes on and it keeps bootlooping plus I'm not able to enter the recovery mode. Please help!! Waiting for your reply..
