You install Rebug Toolbox from the "install packages" option in XMB menu (main menu).
Then you go into the program, and go to the last column, and look for the option "dump eid root key", (your ps3 will restart).
Then you go back into the program, and go to the 4th column and choose, "Change Target ID Type" once done, you will be prompted to reboot. You are now on DEX.
Make sure you check in Rebug Toolbox - System Information. Target Type and Level 2 Kernel are set to DEX for the functions to fully work.
