You don't have to solder gp3, since WP already tied to VCC. In both cases.
Finally I got it to work. I unbricked my PS3 now. It is found that my progskeet's USB does not work when the PS3 is bricked, but it works fine when PS3 is booted normally.
I added a switch on R8 and get the USB connection to the computer first. Left R8 on and disconnect the USB. Then press the button to power on the PS3, connect the USB cable after waited 15sec. Switch off R8 and switch on R7 then the USB connection will stay alive and able to program the NOR chip with single word+static timing then. Thanks, RUT Dark Ronin.
Glad you conquer it) Good luck man!
That sounds like a lot of work. Lol
