Why not? Are you holding up on the keyboard.(Toward the screen)

 

you cant flash an sbf without being in the bootloader. There used to be a rom that would take you back to stock 2.0.1 that you could flash with SPRecovery. Let me see if I can find it

 

I hate to ask this stupid question again but are you sure you're holding up on the D-Pad and not left? It's the up if you're holding the keyboard the right way - horizontally. I don't understand why you would not be able to access the bootloader. That shouldn't be affected by an unbootable phone or broken recovery.
