PS4 [Question] PS4 NOR Chip Swap

[engineer]

Hi,

According to the older FW revert method (for PS4 models which support syscon glitch) one can swap the original syscon chip with a new/blank syscon chip, after having written the original syscon binary dump to the new/blank syscon chip.

Can the same be done with the NOR chip (MX25L25635FMI-10G)? That is, dump the original NOR chip, write the binary dump onto a new/blank NOR chip (MX25L25635FMI-10G) and solder the new NOR chip to the same console?

The MX25L25635FMI-10G is a generic part, and their data sheets doesn't mention anything about effuses. So… in theory it should work.

CUH 1001A, SOP16 NOR chip (MX25L25635FMI-10G), and 100-pin (R5F100PLAFB) syscon chip. All original components.

Cheers.

To answer my own question, yes you can.

I purchased some new/blank MX25L25635FMI-10G serial NOR Flash chips. I dumped the binary image from the original NOR chip, and programmed the binary image onto the new/blank NOR chip. Replaced the original NOR chip with the clone NOR chip. The PS4 powered-up and booted fine.

Cheers.
