Hello Hax.it i put this on the the other hax and decided to put it here;
The main goal of this, is to use alternative points with Teensy++2.0 or Progskeet to downgrade a Cok-001 PS3 motherboard What i used is: - PS3 PSU Model Number:ZSSR5391A to power the NAND externally, - DC Voltage regulator to adjust the voltage from 5V to 3.3V to feed the NAND. - 30 awg Kyner wires. - 48 TSOP clip (just for double check_ since this was for learning and verifying purposes, what i did first is read the NAND using 48 TSOP CLIP with Progskeet to get identical Dumps for both NANDs. after that i started with Bottom NAND (Flash1), unfortunately this NAND has only 4 alternative points the rest of the Points has to be soldered to the NAND it self, so i read the NAND using Teensy + Direct Wiring:
i even soldered to the most difficult Alternative Point as in the Below image (but there are other Alt points to these as you will see in the Diagram at the End)
after reading the NAND, it was identical to the one Made by Progskeet,then i desoldered the wires and moved to Top NAND (Flash0), Flash0 has all the Alternative Points as seen in the image:
So i read the Top NAND and compared it to the Progskeet one, They Matched, before deslodering any thing i checked the Dump verified it t was good and flashed back the Top NAND, very fast.
i move back to the Bottom NAND to write the patched Dump, but i wanted to use the 48 TSOP Clip, so i put it but it was hard to get good dump, since i read the dump again using the Clip + Teensy, it did not match, so i had to put some pressure on the Clip like Here
and wallah got it, Flashed back and now the PS3 is on Rogero 4.46.
Here is the Diagram for Cok001:
