How to extract kernel.img with mkboot script

As I tried instructions to install Linux on Amlogic S905 Android TV boxes yesterday, I wanted to extract kernel.img file found in Android firmware, but Google did not help that much until I found mkboot part of mkbootimg_tools scripts. But first let’s see how kernel.img is created… Google provide a Python script called mkbootimg that combine the kernel image (e,.g. zImage), a rootfs/ramdisk and the device tree (DTB) file with a command line that looks like: However, AFAIK the company does not provide a “unmkbootimg” script, and mkbootimg can only be used to create kernel.img, not decompile it. But that’s what mkboot does, and it works for kernel.img and recovery.img. Let’s retrieve the necessary files first: mkboot is a bash script so we can use it right away: So it can be used both for unpacking and repacking kernel.img to/from the output directory.

Droid Stick A2 mini PC Recovery with AMLogic’s Hardware Flash Tool

In some circumstances, for example by installing the wrong firmware or doing something wrong by playing god (as a root user), it’s possible to brick your device. This happened to me with one of my Droid Stick A2 mini PCs based on AMLogic AML8726-MX.

It also changed some permissions in the system, and it was not possible to restore the firmware the usual way. At the end of last month, dbtablets left a comment with download links to “Amlogic USB Burning tool”, but  I only decided to give it a try today, and after some efforts I was successful. Just make sure you only use this method as last resort, i.e. a standard firmware upgrade does not work, and you’re about to throw your device in the trash bin, because you could brick your device if […]
