We don't really know. Cryonics avoid ice formation with cryoprotectants or via vitrification. And assuming there _is_ brain damage, in theory it's still possible to recover as long as the _information_ of the brain hasn't been destroyed. It's akin to having the mainboard and the read head of a hard disk destroyed, but having the plates intact.
