What exactly do you mean? A recovery menu like the one on a PSP, or something along the lines of Flow Rebuilder?
A PSP-style recovery menu won't save you from a bad NAND/NOR flash chip. We also already have a recovery menu where you can flash PUPs from a USB (in case you mess up your system), so there's no real need to have one in the first place.
(and on a side note, if you need a program that unpacks NOR dd dumps, take a look at euss' ps3tools)
