I think you mixed-up something: the boot logo is just the first image you see, when you power on your phone, after that, the boot animation follows.
But I've created a logo.bin file and I woud like to ask you to flash it by following these steps:
1. download the logo.zip
2. extract the "logo.bin" file
3. start your Smartphone into bootloader
4. open on Computer in the folder with "logo.bin" cmd/shell and enter: "fastboot flash logo logo.bin" (without quotation marks)
I don't have a X4, so you have to say me, if it works properly.
