I have two phat ps3 (CECHG01) - motherboard SEM-001. both worked with version 4.81, and both show the same failure state below: I am using external NAND flasher, I removed the nands (no components damaged during the removal process), and created a valid dumps. (I dumped each NAND 3 times, with verification - everything was OK)

also compared between the dumps - identical. after dumping, I used the PS3 flowRebuilder, and created a unified 256Mb dump - no bad blocks everything was OK. I used ps3 dump checker for 4.81 with the full dump - it was OK, and it was patched.

then I split back the unified NAND to 2 NANDs - also OK. the dumps are marked properly - and was flashed back in the right order. when flashing - i make sure i had no bad blocks, with erase, verification, than dump what i flashed (with verification) and compare to what i flashed - identical. so basically I have valid good dumps - and it was flashed ok, and soldered back perfectly
(Microscope confirms good contact).

When i powered the PS3 it turned on and get to the XMB menu, after ~5-10 seconds it suddenly turned off, and keep giving me the YLOD. I cannot enter FSM, recovery or XMB. I tried several times to flash the original flash back (with verification),but now i keep getting YLOD (after powering the PS3, green led is on for 1-2 seconds, then the red light turns for a half a second and system powers down).

is there anything I can do to fix it? (P.S i have both teensy and Progskeet, but the external flasher is the most reliable and the fastest programmer).

Thanks
 
Maybe you have flashed the nand from ps3-1 to ps3-2 and vise versa ?

But i think you damaged the nand....desolder and soleder it again Oo...

Thanks... I octa check the flash0 and flash1... both ok.

Also, the system did turned on on the first try... and after getting the YLOD, now, even after reflashing again and again (patched and original), i'm still getting the YLOD.
 
you can maybe test the NOR Tristake trick. If this works your PS3 dont shut down and you can try flashing by soldering wires
 
My guess is the stress to the board taking it apart and putting it back together has stressed the BGA or solder joints somewhere an caused a genuine YLOD solder issue.
