I have a little problem.
I builded kernel, but i have got only image and Zimage.
How can i extract ramdisk (for mkbooimg) ? Thanks
I usually do that using dsixda's Android Kitchen
or I leave the zImage as it is, and flash it with some tools (flashable zip that already made to flash zImages)
As far as i know, tearing down kernel with 7zip (or similar) breaks symlinking. I've read that somewhere, don't remember where. Either way, it breaks something. You could unpack kernel.elf with Flashtool, it will give you image, ramdisk.gz, and maybe file called cert or 3 (it depends). If kernel is boot.img instead of kernel.elf, just rename it to kernel.elf.
if you need help on packing/repacking kernel or ramdisk, PM me, I will help you as much as I can.
This should be in Q&A section not in Development section! REPORTED!
Anyway, you can use championswimmer's Android Kernel Kitchen to extract your kernel for getting zImage, ramdisk and the contents of the ramdisk
