I change too boot sound (more discreet than Sony 4.3 one).
In the same way, I also created a white version that some should like...
For eXistenZ roms, special bootanimations are here!
Always make nandroid backup before flashing anything!
To install bootanimation:
1. Put your chosen zip in your SD card,
2. Reboot recovery and flash zip,
Restart and enjoy!
To uninstall and recover default bootanimation:
Simply delete "bootanimation.zip" located in data / local
If you like, click "thanks" and enjoy!
