Ive copied the blesoo7.... to usb (formated to fat 32)under 4gb btw.But how do i install using bm.Yes its down loaded but i do own the game so dont think i'm in the wrong.Just trying to get my head around it.It doesnt show up in bm.Wat my doing wrong?.

if you own the game, why would you download it???

Cause i want to tinker as ya do.Just cant get me head round it(thick i know)but hay ho.

I can tell you that backup manager will be of no help to you if you are using a usb pen.
you need to use the file manager. or a pc and the ftp tool.
research.
