Hello all, I have a PS3 Slim that is on Rebug CFW 4.40 and I will be selling my PS3. I would like to downgrade to OFW 3.55 so I can sell the system to someone that wants the device to be able to install a CFW. I checked the Rebug site and I cannot find any tutorial on how to do this. I also did a search here and either my search was to vague or there just inst anything on this forum. I also did a google search. Maybe the FW is to old.
