First of all i would like to thank you for this awesome guide. It really cleared up some things as i was pretty confused about this (so much for the old modship and esr hacks for the ps2 im used to).
But i have 1 question im pretty sure its already been answered in this thread but cmon its 100 pages long so i hope you don't mind if i ask again
Don't you need a hardware flasher to downgrade to 3.55?
Also what are the chances of bricking my ps3 with this?
