First you need to be rooted(How to: http://androidforums.com/lg-optimus...-gt540-running-2-1-now-everyone-can-root.html) & Root Explorer (Paid App, check here: http://androidforums.com/lg-optimus-gt540/238374-youtube-v2-0-26-android-2-1-a.html ) Now, you have everything except a file... A ''bootanimation.zip'' file... Where do you find one? Google! Search for ''bootanimation.zip'' & you'll find lots of them... Either search for default bootanimation.zip(If you need) or find many cool animations & Download them.. Remember one thing that it should be a 320x480 one, so it fits the screen... Move the zip file to your SD... Now, open Root Explorer... Then Go to /sdcard, find it & Copy it (Long press>Copy)... Press back... Press the ''Mount R/W'' button on top... Now, nevigate to /data/local & paste... You are not done yet... You have to set correct permissions... Long Press on the file>Permissions & Tick 'Read' (All the three) & Write (Only User)... The others should be unticked... Restart your phone & yay! You see the Animation!
