And please, don`t repost wiki instructions or better, use text formatting tags like code, quote... Thanks!

With which firmware? If you instal latest firmware twice, you can't reverse your firmware with that way.

There is 2 bank and only one active in a time. When you flashing a firmware, "hidden one" flashed and it status became visible, but visible one become hidden.
I think you understand the situation.

my faul here are few games with the same filestructure and zip filename. But inside they have different things. Link on my wiki post has the Activate Alternative firmware game (subfolder rollback)

Look at my description with pictures about FFB from my signature. The same you have to do while copying this game to TV.

If your usb is ext3 then you get success. Instead you just call it, miss chmod step
sh + /path to script/revert.sh
