Yesterday, I tried change idps by flashing new nor with new idps. First I backup nor bin by multiman in Rogero 4.40 and downgrade to 3.55 to get eid_root_key. After that I use IDPS changer to create new nor bin and flash with it by multiman.
When I reset PS3 and it say I need upgrade fw 3.55 or higher and can't boot to xmb. But I tried every fw still say error "The data is corrupt (8002F2C5)" or "The data is corrupt (8002F225)". I can go to Recovery Menu and tried all options but no luck.
Can anyone help me?
