PSP Firmware 4.00 Decrypted

psp-firmware-400-250x187 PSP Firmware 4.00 Decrypted

PSP Firmware 4.00 has been decrypted and by the same team that brought us PSP Custom Firmware 3.95 GEN. So what does this mean to us? Well this opens the door up now for either 4.00 GEN or M33 custom firmware. Decrypting the firmware is the first step towards Custom Firmware enlightenment.

From the PSPGen website, translated from French:

“Many PRX’s were changed such that pops popsman, npdrm, np9660, mlnbridge, sysmem, umdcache, sysconf, video, etc.. Good news, it will not pose too many problems for future adaptations for a Custom firmware.

Please note that the NIDS do not seem to have been changed but the file pafmini has yet changed what can possibly ask for the concerns of some compatibility issues.

This suggests that a custom Firmware based on firmware 4.00 will be rapidly introduced
