So here's the story: My friend bought a ps3 with cfw, had 4.60 rogero with 2 games: Gta 5 and Sniper elite.Thing is, he installed Fifa 2018 and didn't work because it needed 4.80.So I installed Rebug 4.82 cfw, Fifa worked but then the other 2 didn't (they just froze the ps3) so I tried to install webman mod, had cobra activated but even then it didn't work, even fifa stopped working.Didn't know what to do so I installed Ferrox cfw, even then using multiman any game froze, now sometimes even the XMB freezes.Don't know what to do anymore, thinking of formatting the HDD and have a clean install.Any help would be appreciated
