Hi, hope someone can help me. My ps3 is a slim one (A PES 2010 PS3 BUNDLE) I remember it to have FW 3.50 from factory and I already have it on kmeaw 3.55 cfw.
I want to format the internal HDD.
To do this żI need to remove kmeaw 3.55?, i don't want to cause any brick or something
My ps3 model can be downgrade using this tutorial?:
