Progskeet - NOR/NAND Flasher
E3 Flasher - NOR only Flasher
These are the best way to downgrade from 3.7x to 3.55/3.41
You need the Adaptor PCB + the 360 clip for your console (Nand/Nor) along with the Progskeet v1.1
Wouldn't even bother with the E3 Flasher, heard alot of bad things about it.
Progskeet v1.1 is where its at, its universal and can be used on more things instead of just a ps3
Its also NAND & NOR compatible where as E3 Flasher is only NOR Compatible and doesnt work with many PS3 Models
The progskeet can downgrade any ps3 model aslong as its not a brand new slim that came with firmware 3.60+ from factory
how do i jailbreak my ps3 from 3.72 to 3.55. i have fat ps3
theres no way this guy will be able to downgrade with e3 flasher, he doesnt even have the knowledge of anything related to modding(no offense) i guess i could be wrong, but most likely he just screw up his ps3 then be ****ed, so my adivce is just to buy a 3.55 ps3 or wait hopefully for karatoks 3.73 jailbreak. unless that Progskeet v1.1 doesnt require hardware mod( which i doubt it, even though ive never heard of it) so ya thats probly your best bet
