In recovery mode, it is the option "Restore Ps3 System".
If you cannot install a downgrader, your "new" hdd is either corrupt or you are no longer jailbroken. Try another known working hdd and if the same thing, then yea you are no longer jailbroken.
but even OFW dosent install . in recovery it says 2.50 and later . and in the normal start one it says 1.97 . so atleast even if i wasnt JB'd i would atleast be able to install 3.55 OFW right ? it happened after i switched HDDs . no CFW ever succeded in install .
