Hi, i'm lastuncas and this is my first post.
I've buyed a ps3break with pic and so i can't update, so i've decided to buy a ps3 key, but i've a question:
The seller where i buy , has only ps3 key v2.1 or 2.2 and i've a fat ps3 so i must buy version 2.1 , right?
This version is less compatible than v 1.1?
If i use v2.1 with backup manager 1.0 and i insert the BD, the compatibility with the games is the same of v1.1 with bm 1.0 and BD?
Can i downgrade firmware from 2.1 to 1.1?
Thanks to all!
