PS5 Modifications

Dumping the Serial Flash

The serial flash being used in the PS5 (at the time of writing) is a Winbond W25Q16JVNIM. It's about 2MB and is 150mil in size. Here's a pinout diagram of the flash.

       +---------------+

/WP+---+               +---+SCLK

In this guide, we will be using a Raspberry Pi to dump the flash (teensy boards may work too) Connect the pins to the GPIO header according to this table:

Connections

Flash	RPI
/CS	GPIO 8
/MISO	GPIO 9
/WP	GND
GND	GND
VCC	3v3
/HOLD	none
SCLK	GPIO 11
MOSI	GPIO 10

Use this site to find the pinout for your Raspberry Pi: https://pinout.xyz/pinout/spi#

I will release my own tools later on, but I think flashrom works for now (haven't tested yet)
