Presenting you the Kernel Flasher tool by faqbly from xda developers. This tool helps you flash kernels in a simple way without increasing your custom bin count.
The procedure is pretty simple, you choose a kernel which you want to use, you put the boot.img file in the root directory of your SD card, flash the tool which is a zip file in CWM recovery and you’re done.
Along with that it creates a backup of your previous kernel image file which should be named OLDboot.img and it should be located on the root directory of your SD card.
In most cases now kernel developers make flashable zip files of their kernels, if you happen to encounter only a boot.img file of the kernel released, you may use this tool to flash it quickly.
If for some reason you want to flash a kernel using this tool which’s boot.img file is located in a zip file, simply extract it using an archive program such as WinRAR or 7zip.
