How to Get PS3ita4.50 DEX?

[kuremonpa]

My PS3 is OFW3.55, I hope PS3ita4.50 DEX.


OFW 3.55 → kmeaw 3.55(rootu_key dump)
→ Rebug 4.21 → Rebug 4.21 DEX(NOR/NAND dump) →3.55 DEX Downgrade → PS3ita 4.50 DEX

Right? and Possible...?

if, my think dex method bad choice,
please tell me OFW 3.55 → PS3ita 4.50 DEX best method. Thanks.
