sorry i dont think the rev 3 or 4 makes any difference ,
im having the same problem for the last week now and tried every possible option. But its always good to have an updated version
there were people for which it was working with rev 3 , others mannaged to get it with rev 4 of hermes's ios.
i'm beginning to guess we have a bad dump of the iso
via usb loader: gh 5 boots to black screen
via diskchannel - > nothing, doesnt even show up (cioscorp 3.5)
seems like a stupid problem but idunno where to look any further
bleh
