Install Instructions
I have created cwm-installable-packages for each of them, as I think it's easier to load them that way:
Make sure feamod recovery is installed, click here for more info
Make sure your ROM supports sanim.zip boot animations
Put the animation(s) you chose on your (external) sdcard
Reboot in recovery (feamod/cwm) - poweroff, press vol-up and poweron and wait till recovery appears
Select "install zip from sdcard"
Select "choose zip from sdcard"
Browse to your bootanimation and select to install it
Select "reboot system now" and enjoy your new boot animation
If it doesn't work, extract the sanim.zip and install them the regular way with Root Explorer or something like that
Please note that they are all sanim.zip based, so please check whether you ROM supports it
