Requirements:CEX2DEXeEID_RKDumper.pkgmultiMAN ver 04.04.03 BASE CEX DEX (20120722) Tutorial: Dump your CEX flash in multiman: To dump flash: mmOS->Select any file->Open in HEX viewer->[SELECT]->[START]->DUMP LV2(NO)->DUMP LV1(NO)->DUMP FLASH(YES) . Install + Run eEID_RKDumper.pkg then get your eid_root_key from dev_hdd0/tmp . Load your CEX flash dump and eid_root _key in CEX2DEX to create your DEX flash (if your files dont show when trying to open them in CEX2DEX type *.* and all files will show). (For NOR flash rename it to my-DEX-flash.EID0.NORBIN , for NAND my-DEX-flash.EID0.NANDBIN) Start up Multiman (the version linked above in thread only) and press X twice on your new DEX dump, select yes 3 times and it will be installed. Reboot and install the DEX firmware of your choice (you can choose any OFW DEX firmware available including the 3.55 Downgrader from ps3devwiki, located here. Also get Exeedy's 3.55 MFW here, it has all the CFW features you'll need. Notes: You can play retail discs above 3.55 on DEX, and can also run a lot more games than CFW / True Blue. You will lose Blu-ray playback after converting to DEX but it should return after flashing back to CEX All retail discs will work on 4.11 DEX converted console as of today.
