You can change the startup sound to match ur new startup splash[if u have done it] by following this tutorial
- Enable CAPS OFF
(caps off is enabling access to locked system folders which are normally not openable.if ur phone is h*a*c*ked by hellox,u have to open the rom patcher app and run open4all patch.if u had h*a*c*ked by older apps like hello carbide,u would have a caps off option to enable)
- Use a file browser(i strongly suggest xplore,if u dont have it,get it from application area) and enable viewing system and private folders
- Download Startup Sound Mod.zip
-Extract the 101F8763.txt in the zip file to C:\Private\10202be9 folder
-Extract the startup.mp3 in the zip file to E:\Sounds\Simple folder
Reboot Device.
Enjoy
