3 Options to install.
First step: Extract downloaded .zip file to reveal "bootanimation.zip"
Navigate to the folder containing "bootanimation.zip" in terminal/command prompt.
Type the following
adb push bootanimation.zip /Data/Local
adb shell bootanimation
Copy "bootanimation.zip" to your SD card
On your Streak open up Root Explorer (or any other app that allows you to copy paste to the internal memory)
Copy "bootanimation.zip" and paste it to /Data/Local
3. Terminal Emulator
thanks nickshertzer, his directions are for drop box but can easily be manipulated for simply copying the bootanimation.zip to your SDcard
BTW, if you don't have / want to get out that sync cable for ADB, use dropbox & Terminal Emulator. Make sure you download the .zip using dropbox longpress first before running following command (requires Busybox / can't remember if it is installed default on Steve's ROM)
su cp /sdcard/dropbox/bootanimation.zip /data/local/ reboot
