I am very new at PS3 if I happen to ask noob question please forgive me. Here is what I am trying ask. My friend had given to me a Demo PS3 slim which have demo firmware 3.7 on it. I had did a such for turning a kiosk unit into a fully working unit, but the firmware were lower then mine.
I had tried the tut, but it didn't work for me. So I am just wondering if I can use the teensy++ to downgrade it to a OFW.
any help would be greatly appreciate.
