(adsbygoogle = window.adsbygoogle || []).push({}); I'm on Rebug 4.78.1 REX with Toolbox 2.02.09. I'm trying to change my PS3 from CEX to DEX using Toolbox but I can't get past the first step. I'm going to "dump eid root key" but it's not actually doing anything.

I select it, my screen goes black, my PS3 beeps three times, and then restarts. I believe this is what is supposed to happen, but then when I go to "Rewrite Target ID Flash" I get a message that says "Please provide the following file and try again: /dev_usb000/DEX-FLASH.EID0.NORBIN". I backed up my flash to a USB drive before trying to dump my key if that matters.

I FTP'ed to my PS3 and I don't see a eid_root_key folder in dev_hdd0/game/RBGTLBOX2/USRDIR. I have two files in that folder that say root_key_475.self and another thats root_key_475d.self but I'm not sure if thats the right thing.

No, you should be fine now. Now that you have your eid root key dumped you should only need to Rewrite Target ID in Flash and Swap LV2 Kernel to go from DEX to CEX and vice versa. Happy modding broski.
