put an old firmware on my mp3 player

[Alexndre]

Hi everybody! I'm new on this forum and my native language is french...
My player use an Action V9.1.52 firmware an looks like a first gen ipod nano.
It have a 128x128 stn display and is 2gb instead of 4gb as they said...
I already have a backup of it that i do with s1clone.
I would like to know what older firmware do you think it can be compatible
with because I would like to put an Ipod-like theme on it.
Have a nice day!

Alexndre, there are hardware differences between 9 series players and the older 3 series players so sadly using an older firmware is not possible on your player.
