Hi there guys,

I am having an issue and was wondering if someone could point me in the right direction, maybe to a tutorial or some decent info on this.

Anyways, I have been tinkering around and teaching myself about building kernels, and roms and just a short while ago finished compiling my first kernel. I have the zImage, and i have tried adding the zImage to Koush's AnyKernel updater.zip but when i try and flash it says failed but is not displaying any errors (Using TWRP recovery) Or I am doing this wrong and need to unpack and repack boot.img with the new zImage?

Any help is greatly appreciated, Thanks!

(edit) I am building on Fedora 17

Unpack the boty.img and repack with new zImage

Re: [Q] how to convert zImage to boot.img
Will fastboot boot boot.img work on the galaxy note for testing a kernel? In case I have a borked kernel I want to take precautions so I don't brick my device.

No to fastboot.

With a broken kernel you should still be able to button combo into recovery and just flash a working kernel .zip

Or..at the very least be able to boot download mode and use Odin to flash the kernel.

Re: [Q] how to convert zImage to boot.img
I have gotten the boot.IMG all packed back up and when I flash it, my phone just hangs up at the white Samsung logo screen and does not go any further. Does something in the ramdisk have to be edited?
