v1.1.0

PS5 SFlash Dumper v1.1.0

Makes a verified backup of your PS5's serial flash (/dev/sflash0, 2 MB).

Features

• Dumps SFlash twice and verifies both dumps with CRC32
• Saves everything in a folder named after the console serial
• Generates sflash0_info.txt with decoded console info (board ID, SKU, region, serial, MACs, firmware versions and more)
• Extracts partitions into a parts/ folder
• Saves to USB (/mnt/usb0), with automatic fallback to /data
• Read-only: never writes to the flash

Usage

1. Jailbreak your console
2. Send sflash_dump.elf to your payload loader (port 9021)
3. Wait for the Backup MATCHED (CRC OK) notification
4. Copy the <SERIAL> folder somewhere safe

Tested on

Relapse / kernel exploit, FW 7.00 – 13.60 (including 12.40)

Notes

• If you see Backup NOT matched!, do not trust the dumps. Reboot and run it again.
• Dumps contain console-unique identifiers (serial, MAC, SoC UID). Do not share them publicly.

Files

• sflash_dump.elf: ready-to-use payload
