In this post you will find the link for the flash tool.
Star the flash tool.
Turn off your phone.
Then press the menu button, the button on the right of the 3 buttons at the bottom of the phone and then connect your phone with your usb cable.
Then the flash tool should show that you are connected in fastboot mode.
Then click on the sign which looks like a lightning. then click on fastboot mode
then click on the right side on "select kernel to flash"
select the direction where the kernel is located, then on the right side at the bottom instead of *.sin, select *.img and then select the kernel, click on ok and wait until the flash process is finished (takes a few seconds).
Now you have flashed the kernel.
