As the title says, is it possible to downgrade a PS3 using the LPC-H2148? I used it to JTAG my Xbox 360, I know that's a NAND and this is a NOR but...is it possible? I'd rather not have to buy a Progskeet or Teensy++. Also, if I DO have to buy something else instead, does it matter whether it's the Teensy++ 1.0 or 2.0? Ta.
