I have jailbroken my PS3 with two different methods; I used the TI-84 calculator and an 1st gen ipod touch (blackra1n 3.1.2 jailbroken). The ps3 is an original fat 60g ps3 running on firmware 3.41. I successfully jailbroken the ps3 and installed the ps3 ftp server.
However, everytime I load the ftp server, I encounter a black/blank screen. My ps3 freezes, I can't exit to the xmb or anything. I've tried putting an original ps3 game into the blu-ray drive and this hasnt worked. I know its not my video output, i've tried both AV and hdmi. If anyone knows a solution, it would be much appreciated.
