Developers Abkarino and EgyCnq have released PS4 Syscon Tools, a tool that will help with repair/modding/”downgrading” of PS4. In parallel, EgyCnq has published a tutorial video showing how to dump/flash the Syscon.
As the name implies, PS4 Syscon Tool intends to be a swiss army knife for backup and modification of the Syscon chip on the PS4. That chip is critical in particular for repairs of bad firmware updates, as it holds information on how to revert to a previously installed firmware.
What is PS4 Syscon Tools
PS4 Syscon Tools is a free tool to dump/edit the PS4 Syscon. PS4 Syscon Tool is developed by Abkarino and EgyCnq.
Combined with a Teensy 2++ and above-average soldering skills (you need physical access to the Syscon chip), PS4 Syscon Tools lets you do the following:
- Dump syscon Flash
- NVS/SNVS only
- Erase Syscon
- Erase Full flash
- Erase Full expect Boot 0 block
- Erase Partial
- Write Syscon
- NVS/SNVS only
- Enable Syscon Debug mode
Other tools such as BWE’s Syscon Writer offer similar functionality, but BWE’s licenses are not technically free: a license for Syscon Writer software comes with BWE’s proprietary Syscon Writer hardware. In this case, a Teensy2++ is used instead of BWE’s hardware offering.
From their Readme:
PS4 Syscon Tools is a free solution (software & hardware) that allow you to manipulate original PlayStation 4 Syscon chip (Renesas RL78/G13). It consists of 2 projects:
- PS4 Syscon Tools (PC client to allow you to control your PS4 Syscon Flasher hardware).
- PS4 Syscon Flasher (Hardware flasher based currently on Teensy++ 2.0).
In a tutorial Video published earlier this week, EgyCnq showcases how to flash your Syscon with the tool:
