CECH2501A delid gone... bad

And since I dug the board out of my trash can, here is a daylight picture. Grey paste/glue/bi-component-thermal-flux-capacitor well visible ;-)

So is a PS3 model CECH-25xx, with motherboard JTP-001, and motherboard serial = 1-882-481-31
Ok, it looks it was a known revision because his serial appears in wiki, seems to be the last revision of JTP-001 motherboard

Now im wondering if all the motherboards with serial 1-882-481-31 have that special version of CELL CXD2992BGB glued to the IHS
Dunno, i guess we are not going to have an answer to that by now unless some other people reports more info about it

Anyway, it looks they was sticking the IHS's with thermal glue since that dates

 

[manples]

Just to report that I've found a CECH-2101A and successfully delided it!! Painter's knife N°1 for the CELL and heat+pry tool for the RSX - with extreme caution this time. Delid process is definitely not for all...

Anyway, fresh MX4 thermal paste, case mod (80mm fan grill above the fan) and I get 60/63 idle with fan at 24%. Very silent so far but I haven't tested games yet. But super happy so far.

Third time's the charm ;-)

I am sad to say that me too got caught by the soldered CELL

what is most intriguing is that I watched lots of delid videos and many CELLs with the "bumps" were succesfully delid, I also saw the video from NSC where he said that the chip had probably melted from overheating... I wish I had saw this thread sooner... my ps3 was also fine with 66ºon cpu and 68º on RSX but I had a ps3 die from Ylod earlier and I knew I had to delid mine if I didn't want it to Ylod again

anyway... I'm off to get a Super Slim ps3 now, I've seen that it is more resistant and the RSX is already delid from factory

BTW my model is CECH3011a and the board had "KTE 001" or something on it i know it started with KTE

probably what am about to say isnt very useful to anyone anymore but mine is also a 3000 kte motherboard but my cell am pretty sure is the old style itsa a CXD2996GB if i remember corecctly i saw no black stuff underneath the thin IHS, so what am trying to say is that if you like the slims better or the 3000 for that matter theres others with the delidable cell

What i don't understand is why you tried to delid soldered CELL? I mean i can understand that you didn't know that chip was soldered to IHS and you made a mistake. But the IHS soldered to chip doesn't have overheating problems. So you guy who destroyed their CELL didn't even had overheating problem but you wanted to delid just to be adventurous.

Actually i wanted to delid because temps were pretty high already 65+ idle and close to 70 when playing

Also i knew that the best way to prevent YLOD is having the system run as cool as possible so no it wasn't to be adventurous it was just regular maintenance


Hopefully i'll be better of with the super slim
I also like that it is very small and portable

 

[snkplkn]

You didn't mention your fan speed. If your fan speed are above 50% to maintain 70c, then you have overheating problem. In case of CELL, this is the first thing you try before doing Delid.

https://www.psx-place.com/threads/t...l-dissipation-without-removing-the-ihs.23066/

Delid is last alternative when everything else fails. Also CELL can tolerate 70c easily without any problems.


Edit - Yes, Super Slims with HEN are better than CFW PS3s because CFW compatible PS3 are very old models, at least 10 years old. You will always find some problems in such old hardware.

 

[victorstk]

and this solves YLOD problems too?

@sandungas @snkplkn @Cosmic-R

just to clear my mind
is it possible to remove this broken CELL and replace it with another from another broken ps3?

it's a shame because the board is in a condition so good, no oxidation no bad capacitors... I don't want to throw it away

There is a unique key inside CELL... that needs to match with some software inside flash chip (bootldr and metldr)... also with the contents of syscon chip eeprom

So... the traditional way to fix your problem would be by replacing CELL, SYSCON, and FLASH (because are paired with each other)

--------
Replacing the flash chip is optional... instead of replacing it you could "rebuild" his contents using data from the "donor" flash
The syscon has been hacked recently... but as far i know is not posible to rebuild the areas related with the CELL key

Perhaps with what we know already about the syscon, etc.... we can patch a way to get to fsm? IF we can get a unit to fsm, then we can qa flag, downgrade, etc without a flasher?

I'm probably speaking pipe dreams here... though... grain of salt..

I cant imagine how many hacks could be achieved by modifying syscon software because i dont even understand how it works, lol, but i guess the qa to downgrade is not going to help to hack the PS3 models not compatible with CFW
The problem is in that models is not posible to downgrade lower than 3.56, and the firmware installers doesnt updates the metldr... so are going to be locked with the new metldr anyway

The reverse engineering of syscon software is very promising though, i guess is going to be posible to patch some checks

I was just speaking about cfw capable units. the non-cfw have hen. I just figure if it's from syscon, then most likely it will be a little more future proof.

UPDATE:

got a ps3 super slim and I couldn't be happier with the console, it is in great condition and it is WAY more silent
the RSX already comes without a lid and the cell is probably better soldered and ultra-tight I couldn't delid it even if I wanted to

I already changed to a high quality thermal paste and wiped the small rust spots i could find on the outer metal plate with WD so that this thing will still run for years!

the ONLY downside of the super slim is that disc tray, I'll have to be extra careful to not let it fill with dust OR
I'll probably just put some tape on the lid and install all my games digitally =P

@manples you should definetly get a super slim if you still didn't buy another ps3

 

[victorstk]

now can someone explain HOW did this guy delid a super slim

well for a start his model looks different from mine already as I can see from the RSX
I assume that the cell in his model has a lid like the slim because I can't imagine someone cutting on a cell like on my model...

Sadly I didn't come across this thread and made the same mistake , I have Done many fats but this one was having some issues figured I'd try a delid for shits and giggles because I have it pretty much down at this point. Chech-2501

Can you tell the motherboard model and serial ? (i mean the serial in big numbers in the motherboard in format 1-88?-???-??)

Sure thing, Was a sad day but Overall its a learning experience
