It doesn't work for me like 1.0 on my debug station...
this is cause we also need a stick like psjailbreak for debug/test units. i tried playing backups with the backup manager 1.1 on my test unit -> IT DOESN'T WORK. also if i replace the original EBOOT.BIN with the debug EBOOT.BIN.
i am on 3.20 and also my psgroove dongle doesn't work. hopefully the stick works on 3.40 or 3.41 fw.
so its not possible at the moment to use a backup manager on a debug/test unit. sad but true, hopefully something makes a working backup manager and stick for us debug/test owners. everyone is playing with a retail unit, so i think it will last long to get a solution on our debug/test units
