After changing my boot sound (from a chinese one to the stock huawei one) when everything went ok!
then i changed the boot animation (again from a chinese to a normal one) but i lost the boot sound!!!
I did all these by just renaming the old files (bootSound.ogg and bootanimation.zip, bootanimationex.zip) and copy the new ones to the same exact folders not with TWRP or something else.
Why this happens?! Inside my original bootanimation.zip the file desc.txt does not contain any information about the sound like s sound.ogg or something like that???
Can you explain me why this happened !? and how can i fix it!
