I am a newbie. Just wondering if there is someway either using recovery mode or system restore to downgrade from 3.72 to CFW 3.55 without using an external device like Eflash. Thanks for the help in advance.
No, there is no downgrading by any means at the moment, except for taking apart your console putting a device on your NOR/NAND and flashing it that way i.e. e3. Well that is how I understand it at the moment anyhow.
