wait a bit before going the hardware way... in this sentence it seems he bricked it at software level

So not a soft-brick?

To do the CEX/DEX conversions is needed to decrypt and re-encrypt an area named EID and it seems the process failed at that point... or whatever you wrote in it was corrupted or had invalid values

That's correct, that was exactly what I was doing and a bit confusing when it came to the editing part with the HxD editor.

So.. the next step would be to take the flash dump you made (before modifyed) and flash it... with a teensy, but the installation is tricky, there are a few solder points that requires good tools or experience... or both

I tried but the damn clip wasn't reading the NAND or no longer making good contact with the NAND legs. I then decided to solder some small wires to the NAND legs but only made it to three :D Keep on getting bridged. I've looked into other ways to possibly read the NAND without having to solder. Tried some micro chips ic pins, complete trash, came across some "electric" tape I think , something similar to the solder mask of a PCB but can't remember what was it and then this expensive $600 tsop48 pin adapter:

could you measure it's resistance? I just want to confirm it is the OG. If so then replicating the mod just requires removal of R2001, no need to add a 47K to R2002.

Sure, what is the proper range for that component?

The other area I'm interested in is the little MOSFET next to the RSX tokins on the back side. Could we get a closeups of that too? Some measurements of the resistors there would be helpful...pretty please?

Yeah, no problem, I still have the motherboard outside. Do you mind showing which one is it? thanks.
 
oh oh so we need a resistor to R2002, cause i see a blue one in the photo. so could be a problem? @DeadEnd have you put any resistors to this area in my console? it plays flawless btw. but if ther is a risk the i can put it aside until things clear out. what you guys said?

I think I didn't change those two resistors at all. They are both populated (if I remember right). I figured if it works fine like that, then no point. I've asked Botakompong, if I remember right he said it is good to put a 47k into R2002 and remove R2001. But he also said if it works without then it's also okay. If there was to be a GLOD, it would have happened when you start the console. So I suppose if you didn't get it, then you don't need to mess with the resistors at all... But nobody can truly say what is it needed for.
 
the console works no glod or strange behavior whatsoever. but it will be better to replicate the mod as sony did. after all its their child. anyway if it come i can perfectly solder smd compoments they can ticking a nerve some time but i can do it

Why exactly did you try switching to a full DEX version anyway? There's not really anything to gain over Rebug DEX as far as I'm aware.

Well, I also talked to him again and he recommended to do it like Sony did. So remove one of them and replace another with a 47k. But again, he says there were no complaints even if those were left untouched.

He also has the refurbished frankenstein board and he has already measured that Sony added a 47k instead of the original one.

PS2 games work fine?
 
yes everything i throw it plays ok. the system is stable. but @DeadEnd was speaking with @botakompong and discover that in cok-001 can found 2 types of syscon one is 201 and the other can be 202. in 201 the ps2 compatibility can have issues. so @DeadEnd a 47k just like we guess. so now what remain to be confirmed is the value of the diagonial one

To be clear. You DO NOT NEED TO CHANGE AYTHING.

I just want a resistance measurement.

Also, I think you guys are getting confused. On a stock COK-001 R2001 and R2002 are populated with 49.9Ohm resistors. What I think SONY did was just remove R2001.

If you need to replicate the mod, all you should have to do is remove R2001. You shouldn't need to replace anything with 47k. The result is the same. I just want a resistance measurmen to confirm.

As for what's going on, why it fixes a potential issue, IDK. If the GLOD occurs on some SYSCON's and not others, then maybe that's why sony official mods do it. Because they all use the special model SYSCON chip. I forget off the top of my head, 304GB?

Point is, if it's working you're good to go.
 
RIP-Felix remember that when one user says he uses gd 900. Made myself curious then, ordering, next unit will be dia001 which I will change only caps and delid because unit is working. I will reply with photos when I get time to finish.

But Sony did replace R2002 with a 47k according to @botakompong and his frankenstein . What would be the reason for it then? Also as i've said before, in case of @truemaster's board, I did not remove R2001 neither R2002. I left them in stock configuration which is 49 Ohm. Yet it still works fine like that, but why ?
 
Does botakompong have an official Sony refurbished? AFAIK he's only talking about the mod he and Kiaw made.

The math for a voltage divider says it doesn't matter the value of resistors used. The only difference having a higher value makes is lowering the voltage closer to zero Like 0.0012 instead of 0.012. The threshold for low voltage logic is already met, so there is no reason I can discern for adding a 47k. Just extra work.

It looks kinda blueish, the OG 49.9 ohm resistor is blue. So that "might" be the OG. @devbug_mind could you measure it's resistance? I just want to confirm it is the OG. If so then replicating the mod just requires removal of R2001, no need to add a 47K to R2002.

So I measured it's resistance and it shows 26. If I continue measuring for a longer time, the number goes down to 25.9/8. Is this normal and does it goes back to 26?
