I just want to share my 1st boot logos...This was made by me and I gave effort to do all of this ^_^
I made it flashable zip to install it easily using CWM recovery or other custom recoveries..
Note: this won't brick your device but flash this at your own risk...
Guide on flashing this:
1. Reboot to your custom recovery
2. Do install zip from sdcard
3. Choose your desire zip that contains the logo
4. Wait until the flashing complete
5. Reboot system now and see the changes
