For those of you who want to extract the 3.72 keys iv'e worked my ass to do it so here it is:
Put latest UPDATE In a flash stick and update your console wait until the ps3 goes to updating in recovery and unplug the the POWER CABLE now before you plug it again put another flash stick in the PS3 and power it on. DONE
NOW YOU GOT THE RAD SCREEN OF DEATH!
Let me know if it helped :D
