I asked you in a PM about validating and you helped me understand it a whole lot better after my 1st downgrade you also urged me to check out the wiki validation pages which I did and they helped me understand Some of the stuff like hdd identification and other tit bits. Since my 1st downgrade I have followed your guide only for validating dumps and haven't bricked a console yet. (Touch wood). I can't understand the resentment shown towards you by the wiki. I gained some good knowledge from your guide and also find the wiki a great source of information. But for downgrading consoles I believe your guide is an ideal learning curve for beginners. The title says it all IMO. It's a crying shame the wiki won't embrace you and work with you instead of against you.
Just my tuppence worth.
