= Dump and Restore =


== Method 1 ==
We are able to make a 1:1 copy of a PS4 Syscon and put it on another chip. This allows to install a dump of a PS4 Syscon to a brand new chip then swap it.


Based on the attack outlined by Fail0verflow [https://fail0verflow.com/blog/2018/ps4-syscon] '''Wildcard''' designed the following glitch using a Teensy: [https://github.com/VV1LD/SYSGLITCH].
This is often used in firmware revert [[Downgrade]] method to avoid having to flash the same chip each time one wants to revert firmware but instead only have to swap the chips.


Using '''Wildcard''''s shellcode but using a different methodology on his GitHub, you can copy the original Syscon and dump it to a new Renesas chip with comparatively greater ease. '''Guide available on BwE's GitHub.'''
= Syscon glitching =


You can also flash to the original SCE syscon using a different shellcode but this is a commercial product sold by [[User:BwE]].
By glitching Syscon, it is possible to dump its EEPROM, including NVS. Test


== Method 2 ==
To be documented.
