I have been researching this for a while but I haven't been able to find any clear answers. 1. If I power the Teensy via USB then will it have enough power going to the NOR to flash the chip without plugging the PS3 in? 2. If I power the Teensy via the VCC on the PS3 then can I just connect the PSU and leave everything else unplugged? 3. Will the board/chip be ok (grounded-wise) if I read/write the downgrade without reassembling the PS3? I am concerned that the wires (26 gauge I believe) will shift and snap off during reassembly so that is why I would rather flash it before reassembly. Thanks in advance for any help people can provide.
