Forgive me for throwing darts in the dark, but might there be a way to modify the OS on a rooted Droid 4? If so, there could be a way yet.
We can install custom roms and use kexec kernels. The Droid 4 has been pushed as far as it can probably go now that it's on the end of it's lifespan.
At this point I would wager the bootloader will never be unlocked. Dev is almost dead for the D4. If Android 4.3 sees it way to the D4 I'll be a happy man.
