If we need to, a K4 could use the same method as a K5. Flash a diags image that has SSH pre-installed.
Or use another jailbreak method (like my "secret" one for K4/K5) that probably still works. It can even push a reverse shell without modifying anything on the kindle. Do we really need it yet?
And the K5 ".stgz" method might work on the K4 now too.
