Now that we have the real master key, developer evilsperm was able to port over PSGrade to various USB devices. PSGrade will allow you to put the PS3 into Factory/Service Mode for the purpose of downgrading the PS3 from firmware v3.41/3.50 to v3.41. Below, you can grab the PSGrad hex files for the appropriate USB device(s) that you want to use for downgrading.
- Minimus 32
- Minimus v1
- Teensy 1.0
- Teensy 2.0
