PS4 4.55 Kernel Dumper Gets SBRAM Support by Zecoxao

Since the last PS4 Kernel Dumper revision and 4.55 Kernel Dumper port, today PlayStation 4 developer @zecoxao passed along word on Twitter that he's added an SBRAM dumper for 4.55 users which is required to obtain the 4.55 uninitialized SBRAM that contains minila, eap_kernel and compressed eap_kernel.

He credits both vpikhur for original exploit and VVildCard777 for a portion of the code.

Download: 455-KernelDumper-sbram.zip / GIT / 455-KernelDumper.7z (Compiled by ohcHIT)

From the README.md, to quote: 4.55 kernel dumper POC with debug settings/TID patch/Jailbreak/Uart enabler etc

Compile with your PC's IP listening on port 9023

On PC you can do to listen:

socat - tcp-listen:9023 > kernelDump.bin

and to send:

socat -u FILE:payload.bin TCP:"PS4 IP":9020

you can then trim out the socket prints or you can adapt it with 2 sockets, one for dumping, another for logging.

To compile for 4.55 you need to use an *** with changes for 4.55 support, i have used https://github.com/xvortex/ps4-payload-***
