(adsbygoogle = window.adsbygoogle || []).push({}); Hey, so i have 3 PS3 models i want to downgrade. And i am going to buy an E3 downgrader if it is working.

The first is mine which is: CECHL FAT
2nd PlayStation 3: CECHG FAT
3rd PlayStation 3: CECH-2004B SLIM


I have followed the charts but i still don't understand to be honest.
It says downgrade-able to x.xx but it still says flash readers: no.


My Question:
Does the versions above work or not? I know mine works but how about theirs?

Look if it says NAND or NOR.
NAND can't be downgraded by an e3 flasher while NOR can.

Working:

Not Working:
2nd PlayStation 3: CECHG FAT
