If the DTB can be at any flash location, you can for example have a fall-back version which is used to bring up U-Boot in a minimal configuration for recovery mode if the new DTB fails to work.

I think that a "recovery DTB" would have to be part of U-Boot itself to be effective. If the normal DTB is not available, then it's likely the backup one would also be unavailable.
