Is there a method out somewhere which looks into External sdcard first and ,if there is a kernel and/or Rom wthin it, starts it?
And of course if there is none, phone starts the Rom at eMMC.
I mean, some thing like Windows boot order:
First check Ex Sd Card, Then HDD.
Whicever has a botable media, then load it.
I wonder that.
