Dear community!

As I am an E3 Flasher Hardware Downgrade Newbie, I am curious about the exact usage possibilities of the Flasher Limited Edition.
I have a downgradable Ps3 Slim and I was on DEX before, therefore I have all the files and dumps needed. Now what I am curious about is can the E3 Flasher be removed after downgrading to downgrade another PS3? My Private CID is banned on my OFW because I once accidently updated my PS over a disc, that's why I want to downgrade again. Is it possible to put a new real stealth CID on my PS3 with E3 Flasher and update it to OFW and Dualboot the CFW/DEX on the E3? Furthermore what are all the cables for in the LE Box and where are the current update files for the E3 Flasher to reuse it after first time use. Maybe some professional of you can give me a source where the E3 Flasher is presented in detail with alle the possible usage methods and Tutorials!

Thanks in advance!
