Introducing: Hi I am new here. Hope this is the right forum part for this. If not I am open for a teaching and pls place it to the correct place, thanks. Situation: I bought a needed PS3 slim CECH2004A. The user before me said it was jailbreaked already. But there is no FW installed. I have no information about the CFW what was installed before. When I start the PS3 it turns on normally and I get into the install menu, also the recovery menu functions normally. Problem and Question: The PS3 does not recognize any FW, no CFW and no OFW. It says I should install an FW of the version 2.70 or higher. I tried OFW´s and CFW´s with higher version. It always says it does not recognize a suitable FW pls put in a stick with suitable FW then. I tried that in the normal menu and in the recovery menu, also tried the other points in the recovery menu and then tried to install. Same thing. So how can I install a CFW on this PS3? And so on...: If anyone need more information just let me know. Thanks for reading already.
