You cannot downgrade through usb only. You need hardware. You will not get RSOD, even if you did there is a fix for that.
Is there a way to Jail Break my system using software only without going through the E3 FLASHER DOWNGRADE TUTORIAL - INSTALLATION FAT (Khalkedon) - YouTube
Could there be a way to just use a USB memory stick and Jail Break by downgrading my firmware to 3.55 CFW?
If not, where can I get the kit like on
