Thanks to some reverse engineering work by Chendochap, SpecterDev was able to add 4.50 support into the PS5 Kernel exploit, meaning the exploit is now fully functional on Firmwares 4.03 and 4.50.

The changes to support firmware 4.50 were “minimal” in the end, being different offsets required for some function calls in the exploit. The exploit files now work for both 4.03 and 4.50 with the same files.

For those of you who just join us:

• A PS5 Kernel exploit was released by SpecterDev a few days ago, based on a disclosure by TheFloW, and involving the work of a dozen hackers
• That exploit was initially only for firmware 4.03, but is now compatible with 4.50
• The exploit is fairly limited, and in particular does not allow binary execution, only limited read/write of specific memory zones with a ROP chain

If you’re looking to get a 4.03 or 4.50 PS5, we have a series of tips on how to find one here.

If you are on firmware 4.03 or 4.50, we explain how to download and run the exploit here. (you’ll need to download the recent update for 4.50 support. No particular need at the moment if you’re on 4.03 and already had the exploit running)

If you are on a firmware below 4.03, there are people saying you should update, others who say you should say on a lower firmware. Honestly, it depends if you think you have the skills to help digging further into 4.03. Otherwise you might want to stay on a lower firmware, until something “useful” for the end user gets released.
