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
