Hardware read/write

Hints

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