PS3 Bought delid CECHC03 with BitTraining error help

[Adrinator2212]

Hey guys!
I bought a broken CHECHC which supposedly stopped working after an "overheating issue". After opening it up I found out that the previous owner tried to delid it and damaged the CELLs soldermask by doing so. Reading the syscon, I get a 4401, then a 3034 error.

Looking under a microscope I dont see any broken traces on the CELLs die, but Im not sure if they damaged any of the CELLs solderballs. Or maybe there's a fuse that can blow if any of the CELLs traces get shorted by the heatspreader?

Where should I go from here? Should I reflow the RSX to see if this (temporarily) fixes the problem or should I start with the CELL?

The console only has an uptime of 3 days, so I'm not sure if a RSX substrate issue can manifest that quickly. I do own a reball station but need to make a brace for a PS3 first.

I hope you guys can help me out, first time working on a PS3

Try to hold the RSX or CELL down with a slight pressure (not too much) and while doing so, boot up the console. If It boots up normally while you're pushing It down, It indicates that there is BGA defect and will probably need a reball.

Good idea, haven't thought of that. Unfortunately putting pressure on either the CELL or the RSX did not cause the console to boot.

I also found a forum post where someone apparently found the traces that cause a BitTraining BE:RRAC:RX0:GLOBAL1:RX_STATUS error but on first inspection the traces seem fine...

On the second image you posted, on the upper right corner there seems as It might be some damage. While they do appear fine It's still possible that the previous owner cut a some really tiny copper line. If you check online, you can find some images where the traces have been cut when attempting a delid, and the damage seems way less than on your board. Regardless I suggest you try a reflow or reball (since you have the equipment) and go from there. If that won't work then probably all you can do Is replace the CELL.
