I don't know if this is the right place for this, if you think otherwise - move the thread.
I have two consoles PS3. One is CECHC04-60GB with firm. 3.66, and the other is CECHG04-40GB (with a lot of YLOD) with firm. 3.55-kmeaw. I have good soldering skills and I want to ask if I can take the two NAND CHIP from the CECHG04 model and put it in the CECHC04, because I can't downgrade from 3.66?
