I need help. I'm desperate. I need to know how Jocose placed the switches.
I have a dual boot OFW 4.31 <---> CFW 3.55, but when I upgraded to last Rogero CFW, the official firmware stopped working (three beeps and shut down). The CFW works fine.
He said he applied the e3_downgrade to the E3 NOR FLASH? How?
You cannot duel boot 4.xx OFW and 4.xx CFW
