Have you tried a battery pull?

How long was it stuck on that screen? If you applied a major update, it can sit there for 15 minutes or so recompiling apps before it finally boots. The more apps you have the longer it takes.

You might also try booting to the recovery menu and clearing the system cache.

As for recovering your data, unless the phone will turn on in some fashion, then there won't be any way to access your data.

If split firmware is available flash it like normal and use the home csc instead, it might or might not work. Either way no harm no foul.
