I want to ask that what's the structure of a zip format Android Rom. I have unziped some of them. But I couldn't figure out how the boot loader flash install them on the mobile. Anyone could tell me what exactly the boot loader do?
I am familiar with Linux. So I want to know some low level things. I wonder if I could cross compile the Linux kernel and some Linux's tools(like CLFS project) and install them on the mobile.
Anyone has some hint? Thank you!
It depends from the updater-script.
If there is a boot.img (kernel+ramdisk), with the raw command, the boot.img will be flash on boot partition.
All the other folder will be flash on system partition.
You should watch an updater-script which is in META-INF/com/google/android or something like that.
