Alright, thanks for the clarification I'm also curious about his method maybe I could a cex norbin and then use the other guide to convert back since there are more people trying that method and have better support. GBAtempers any suggestions/opinions are advisable right now befor I do something stupid lolmy.dex-flash.eido.norbin is a modified dump that turned your console in DEX. Original should have CEX in it. Or it can be called flash_stor_35500.bin.
There is a fresh manual about converting. Creator promises that its legit. I'll wait for first comments http://www.ps3news.com/forums/ps3-g...-simply-work-sure-always-no-brick-124824.html
As for the dongle... It only needs if you bricked your PS3. It can put in service mode and recover it.
