(adsbygoogle = window.adsbygoogle || []).push({}); Hi, im trying to switch my cfw from Rogero 4.55 v1 to Something like Rebug. I am wanting to switch to a firmware with dex so i can use better mods. Basically my question is can i switch from rogero to rebug without downgrading first? Also, if i have to downgrade first can i do it without a flasher on a jailbroken ps3?

And what is the md5 checksum thing i keep reading about when i look up different cfw's, and what is the qa thing? Sorry im kinda a noob when it comes to this stuff.

so can i use rogero on dex???

the only dex firmwares are PS3ITA or REBUG
