Default [Q] any chance we could use kexec to boot cm?

Well like the title says I was wondering if we might be able to use kexec to boot cm on our devices. If I'm not mistaken that's what is used for the droid 3 to boot cm

This has been discussed many times here and in multiple other device forums. At this point, it has not been implemented into SafeStrap. I am not sure if it is possible or not, nor do I know if hash is working on putting it in. He is aware of it though.

kexec uses a hijacked kernel module to direct to a different kernel placed on the SDcard. Sort of like how SS works, but a bit differently. All SS does is direct the kernel to a different image. Kexec needs a hijacked module to load an insecure kernel. While this sounds easy to implement, trust me it will most likely never happen with the note 3. The problem is that the note 3 doesn't have any modules. And don't ask about inserting them, because the kernel will not run them. They are completely disabled in this kernel. That property is set when the kernel is compiled, so with it being disabled, we cannot enable it, and we cannot hijack the modules, because they are completely disabled.
