I have a CECH-2101A PS3 that I got from an online auction site. I think that it is bricked with the FW 3.56 hdd problem. When I turn it on, it tells me that the system software cannot be run correctly and to reinstall 3.56 or later. When I try to install any FW, it tells me that data is corrupt. I don't care about downgrading since this is a second PS3 (my 1st is a former kiosk system that is running KMEAW 3.55) Can you unbrick this system?
