PS3 NAND CECHA-G 4.21 DEX > 3.55 DEX > 3.55 CEX Success Rate?

[sumolx]

I have been doing an endless amount of research and have not found a definite answer if people have successfully reverted their NAND PS3's back to retail mode. My model happens to be CECHE. While searching through many sites... I've only found one person that successfully reverted back. However, they had posted zero information on how that was obtained.

My question is... Has anyone successfully restored their PS3 back to CEX? Any help and tutorials that were successful would be greatly appreciated.
