Hint
On Board Dumping does not work (it works with VCC pin lifted). To Read/Write the chip in the safest way possible, you will need to desolder the Macronix Serial Flash from the PS4 motherboard and use a external flasher like the Teensy and SPIway or the Raspberry Pi and JAISPI. For the desoldering part you should use a Hot Air SMD Rework Station like this one and a nozzle to only heat up the pins of the chip.
