[Answered] PS3 CECHE 3.61 YLOD during hardware downgrade help?
After flashing my modified dumps then the ps3 would turn on with a green LED and after about 20sec it would go back to standby. No beeps or red LED.
while waiting on my service dongle to come in then I got ahold of an Iphone 3G that a friend had and set it up for the PSFreedom exploit. It didn't work for me after multiple attempts so I just waited for the dongle.
Once I got the dongle in then i turned the PS3 on with out anything connected to the USB and I got the YLOD... I then flashed back the original dump and verified it using progskeet. still YLOD.
I researched YLOD and figured maybe the console was about to have a solder issue with the RSX anyway and all the messing with it caused it to happen. I then reflowed it, no change.
I pulled the heat spreader off the RSX and felt for it and the CELL to heatup when power on a few times and they do... So here is where I am now but could use some advice form some of the experienced ones here.
I had two good dumps from each chip and using devwiki I dont see an issue but maybe I am missing it.
Maybe my data on the dump that pertains to the console keys is still good and I can plug someone elses good data in the other places of the dump?
If anyone wants to verify the dumps for me then you can download at http://www.mediafire.com/?khz39hdjmd4da
all powers supply rails looks good, fan kicks on too
bad harddrive? it acts fine on the PC so I formatted it and also tried another good 1TB drive
rig is not setup correctly when powering on? I connect the power supply, fan, and HDD (may not need HDD connected though?)
I have another CECHE and a CECHB coming in too that each have some issues reading disc but I got cheap so I figure I can fix them and sell them if I can get this unit going.
YLOD means somethings wrong on the hardware or software, it does not limit only with overheating issue with reflow or reball solution.
Since the thing "YLOD that is" triggers during hardware downgrade, this is more fault on your SYSCON, and the thing that SYSCON is screwed up , that means your SOL. As of the moment, there are no ways to recover from SYSCON bricks. It's possible to recover from it but no one attempts too since it's inside the Cell's EEPROM you will be dealing for. and there is no way you can access that with handy tools today.
