Hi A1600 users, if you don't want to flash your A1600 to modded firmware, don't want to install any apps to change startup & shutdown animation, just follow these steps for easy change of on & off animation:
1. Using XP tool go to ezx_user/download/appwrite/setup
2. Browse to ezx_themes.cfg & open it with text.
3. Replace Theme configuration with these lines
[THEME_CONFIG_TABLE]
PowerOffScreen = /mmc/mmca1/themes/off.gif
PowerOnScreen = /mmc/mmca1/themes/on.gif
Note: Don't change Wallpaper configuration.
4. Now go to File manager > Memory card. Create a folder "themes"
5. Put your desired .gif file in themes folder & rename them as on & off respectively.
6. Restart your phone.
