I am new to the scene. I have a 160GB Slim CECH2501A PS3 running Official 3.66 firmware.
From what I have understood reading all these posts is
CEX - PS3 running OFW
DEX - PS3 running Demo / Debug FW
My question is can i update from 3.66 Official to 4.11 DEX and then downgrade to 3.55 DEX ? How to convert my PS3 from CEX to DEX.
Kindly excuse and correct any wrong ideas that I may have
