well do u know about the stuff, i already know about the installing e3 flasher installing process but the website says "We renew two file to fix game problem after downgrade to 3.55 .Please note don't install any other 3.55FW after downgrade to 3.55, otherwise will have brick risk !" bt im also getting a trueblue (jb2) so that i can play the new games and stuff but that says " Before you may use True Blue, you must first install the 3.55‐Dongle custom firmware onto your
PS3. This is similar in function to the well known kmeaw CFW; however it also includes modifications
which allow True Blue to operate correctly. " idk know what to follow :/ and i dnt wanna end up fucking up my ps3.... here are my sources
