UPDATE 3/27 Thunderbolt Bios Boot Animation with sound
This has been floating aroung for a couple of years now so I take no credit for the original idea.
I have redone the boot animation to see if this will work for those having issues with the original. Please give this one a try.
I simply edited all of the images to match the specs of the Thunderbolt.
When booting it has a sound of a hard drive starting up with beeps like an old PC.
This file greatly speeds up the boot proccess of the Thunderbolt as well!
The original file is about 3meg, this file is just over 1meg.
Animated gif preview:
The attached zip file is not a flashable zip, it contains the boot animation.zip and the mp3 sound file. Open the zip file and copy the bootanimation.zip and the FinalThunder.mp3 to your computer so that you can copy them to your phone.
Depending on the ROM you are using place the 2 files in the following directory on your phone. If you are unsure, just look in the directory and if it has bootanimation.zip and FinalThunder.mp3 then you are in the right place.
You may have to set permissions on both files to rw-r--r--
(You could also use adb to push the files to your phone if you would rather)
If you think you may want to revert, copy the originals somewhere on your SD Card first.
