nand downgrade problem - PS3Hax Network

ldh888 · 04-14-2013

Hi, all I got some weird situation on my phat ps3 with 4.11 OFW(CECHB MB : COK 001) when I try to use programmer to program nand.

All went fine at beginning, desolder nand , read T/B nand third times each, compare, validate dump, patch with rogero dowgrade patcher 004, and flash patched bin back to nand, solder and powerup ps3 I got :

1. with downgrade patched dump, ps3 pwed on with hdd led blink for like 5 secs and turn off. Can enter recovery but it still showing need 4.11 and if choose update system it will freeze and become YLOD.

2. flash back original dump ps3 logo showing and enter xmb with screen freezed and become YLOD too.

3.desolder nand again and read with programmer and the dump is different than original or patched bin <--why???

hope some nand expert can guide me maybe some where I have do wrong.

btw, my nand chip is using SAMSUNG K9F1G08U0B-PIB0 my friend told me its same as K9F1G08U0A-PIB0?

regards,

Not dehashed. Original was reflashed badly. I'm guessin' - Why would I know anything about NAND
