No offense @
Annelies but this thread is a waste of space if i ever saw one....... I could sum this up in three steps...... install OFW 3.55, reformat your HDD, upgrade to latest OFW........... sorry but that is just common ****ing knowledge

also the rest of your steps are wrong..... if you don't want to reformat...... you delete all **** then run ps3ninja not the other way around..... what you recommended is like washing your hands before you piss... not after
