Earlier today we covered the
PS4 MTX Key Resellers, and for those interested in further homebrew / non-profit development comes a preliminary PS4 MTX Key ModChip hardware analysis for the
gamesharing method used on PlayStation 4.
So far we've seen specifications on the
W29N01GZ NAND Flash Memory, a
Macronix MX25L25735F Datasheet and some research from scener
@Luckystar via Chinese BBS
A9VG.com.
To quote, roughly translated:
PS4 MATRiX Key Chip Crack Hardware Analysis

PS4 MATRiX Key is polished, so according to the photo can not be analyzed. Only from the PS4 fly line chip start.
- PS4 1000,1100 models are MX25L25635FMI-10G 16-pin
- PS4 1200, Slim, Pro is on MX25L25635FZ2I-10G 8 pin
Capacity 256Mb (32MB), is SCEI CXD90025G ARM low power coprocessor use. Sony does not explain the role of the CPU, but now generally speculation for the network, DRM and other background behavior. MTX 6 fly lines are respectively.
MX25L25635FMI-10G
MX25L25635FZ2I-10G
- CS # Chip Select
- SCLK Clock Input
- SI / SIO0 Serial Data Input (for 1 x I / O) or Serial Data Input & Output (for 2x I / O or 4x I / O read mode)
- SO / SIO1 Serial Data Input (for 1 x I / O) or Serial Data Input & Output (for 2x I / O or 4x I / O read mode)
- VCC + 3V DC Power Supply
- GND Ground
In conclusion:
The MTX Key deletes the coprocessor by writing data to NOR Flash. So that the PSN wrong that the PS4 has been lifted commonly used, but the actual PS4 did not lift. The biggest problem with this approach is whether Sony blocks the crack through system updates.
