I have done research and found a couple of sites and links that say you do not need an E3 flasher, progskeet, or teensy or whatever other board you choose to use. I was wondering if anyone on here has come across this and if there is validity to it. PS3 Downgrade From 4.30/4.25/4.21/3.60 To 3.55 With Normal USB It is just a simple youtube video. No surveys or anything on the download as i have the program opened in my computer. I only have one ps3 and would prefer not to brick it. Model of my PS3 is CECH2101B, so I know it can be downgraded. I just hate soldering and buying something that is overpriced.
