The flash IC is located at the bottom center of the mainboard. Sadly,
access to the IC is blocked by the magnesum frame, so you need to disassemble
the entire laptop and remove the mainboard.
Below is a picture of IC on the mainboard, with the pinouts labeled.

The chip will either be a Macronix MX25L6404E (shown above) or a Winbond
W25Q64CVSIG. Do not rely on dots painted in the corner of the chip (such as
