How to decompile android kernel within android itself? How do I decompile kernel.bin of my android 4.1.2 kernel on android itself?
Is there an app that can decompile kernel.bin or any methods for decompiling kernel.bin?

Thank in advance!
No. You can't decompile within android. Not only hardware isn't probably strong enough for compilation/decompilation in most cases, but how do you plan to edit such a huge code in android itself? You will infact need special editors like notepad++ or gedit even in PC to organize the code and be able to understand it to edit. Plus its not "kernel.bin", its " boot.img".

So well, PC is only way for now ;)
