android magic header not found at start of boot img

[Joschi]

Hello Altogether!

First I have to say: Im totally new into things like Android and stuff like that...so please be gracious when I ask silly questions!

Some weeks ago I bought a MK808-b and I was really impressed by this tiny little device. After flashing Bobs Rom to my device which was sadly not working for me I flashed back the rom of my **** seller. (update_mk808b_box_400j1)


To understand how everything really works I thought that it would be good....to dive deeper into the substance! Therefore I start to learn more and more about Android, Roms and stuff like that...

Now I try building my own ROM....just to learn how it works!
Ok ok...for the first time I try to modify a Rom which is working on my device.

Now I got a problem and I dont know how to manage this:

I use cygwin and the kitchen. I installed the cygwin with the kitchen and everything seems to work fine.
With the help of Terminal Emu and BusyBox I packed my system folder and saved it to my external sd card.

su

busybox tar -c system/* >> sdcard/system.tar

After that kitchen want to have the META-INF Folder and the bot.img. I tried a few things to get the boot.img out of this working rom. With the help of RK29xxImageTools_v2.1 I got it now.

When I now want to set full root to the Rom.... the kitchen alway tells me:

[B]
1) Warning! android magic header not found at start of boot img
2) Error: zimage is empty!
3) No Ramdisk found![/B]

Im not really deep into this...so I dont know how to fix it!

Any hints from the (real) professionals?

Thanks in advance...

Thanks...

thanks for you quick anwer and your hints! I promise.... I will closely read the links you posted!

One question: Is it really true...that its unpossible customize Roms only with Windows!? Do I really need a Linux machine?

[900supersport]

I only use windows to test flash a new ROM. Others use windows quite a bit and run linux as a virtual machine. As android is basically a linux kernel then you are best embracing it. Ubuntu and Linux Mint seem to be the versions to go for, both will dual boot with windows or work in a virtual machine.

Time 4 Linux again!

Ok...I see...
It´s time to set up a VM!
