There is a hope for AOSP based ROMs for N3 (Details)
Over @S4, developer @jeboo
discovered an exploit that allows us to insert kernel module into stock kernel while bypassing the signature verification. So using this one could *theoretically* use kexec to boot a second kernel over the stock one.
But here is the dilemma N3 has kernel modules disabled
(Big fu to ATT) while S4 can have kernel modules..so they can get kexec running without any major problems.
So us N3 people would have to modify stock kernel module (since we can't insert any new ones) and this exploit allows us to do that because we can modify stock kernel modules without triggering signature verification. All in all we have some hope of getting kexec working with our N3
I'm no kernel expert but this looks promising. Also dont update past MI9 because that kernel exploit might be patched. Only way to verify is to send boot.img to @jeboo
