PS3 Corrupted NAND / NOR

[tungatung]

Is there a method to unbrick a ps3 with corrupted NAND / NOR if the backup of original NAD / NOR is not taken.

It depends what and where are the corruptions.

It's really not that simple that there is some post that explains everything.

so basically there is no *easy* way to recover a console with corrupted flash without a proper dump of the flash.

Yeah, you would need skills to be able to build a frankenstein dump using another dump as a base, then overwriting the unique per console areas from a dump taken from the actual console. If any of the original unique areas are missing or corrupt there is no way to fix it.

In NOR you get about 2Mb of Flash Memory that is occupied by various things such as revocation data, OtherOS related data etc.. Some of that stuff can probably be worked out if you possess the skills & knowledge.
However a fair amount of the 2Mb contains per-console data (from factory) which doesn't get updated during a PUP installation, without a valid backup, any corruption of that data usually signs the console's death warrant..
