Hi guys , im kinda new here but im not new to the hacking scene. I'm only new to the PS3 hacking scene.

I have a few inquiries regarding downgrading a PS3 Cechb-2001b fw 4.11

Fisrt off i already started the downgrade process but while running around searching for an answer for the problem that i will outline below , i realized that some ps3 can brick if you downgrade them lower than the firmware it came with

My first question is how can i verifiy the orig fw of a CECHB-2001b ?

Secondly , I was following the video tutorial on E3's website to downgrade
and everything went smooth , i got a few bkpps3.bin and im at the part where you have to unplug the ps3 and enter factory service mode. I tried it with my ipodtouch 1g and ZaxtronFrontEnd img with no succes. the ps3 never shuts itself off and boot into xmb while on the ipod i can see device5_wait_ready

The ipod is plugged into the most far right usb port . Where am i failing ? am i forced to buy a e3card reader or a ps3Downgrade dongle ?

Thanks
