Note:
This is not bootanimation, this is the splash screen (the 'Zuk' boot logo which is displayed when device is switched ON)
This is for ZUK Z2 / Z2 Pro Only ..
For other devices, please send me your splash.img so that I can create a tool for you too.

Requirements:
1. Rooted Zuk Z2/Pro (any ROM)
2. Terminal Emulator app installed.

STEPS to create splash.img:

Before proceeding, make sure fastboot is setup properly in your computer (just incase something goes wrong)..
It's not yet tested by anyone.

1. Make sure you have a 1080x1920 picture in PNG format.

2. Download & Extract this: Zuk_Z2_Splash_Logo_Maker.zip

3. Now rename your picture as logo.png & replace it inside "pics" folder of the extracted folder.
(Similarly you can replace battery.png and usb.png if you wish)

4. Finally, run the 'CREATE_LOGO.bat' to create splash.img , which you can find inside the "output" folder after completion.


STEPS to flash splash.img:

1. Transfer the splash.img to your device's Internal Storage.

2. Open Terminal Emulator & enter the following to flash it:
Code:
su
dd if=/sdcard/splash.img of=/dev/block/bootdevice/by-name/splash
(You can also flash from fastboot as given below)

Note:
Incase something goes wrong or device doesn't bootup, flash the stock splash.img from fastboot like:
Code:
fastboot flash splash splash.img

@GokulNC, thank you for your tool.
I want to change Warning message for unlocked bootloader with custom picture. I remember there was some way for Motorola phones: https://forum.xda-developers.com/201...ssage-t3177801
Is it possible to use this way for Zuk Z2?
I'd like to find solution but I don't know how to unpack splash.img.

By the way to flash splash we must use the following command:
Code:
fastboot -i 0x2b4c flash splash splash.img

Nope, that's ROM specific.
Check the ROM's source to find where it is. IDK

In their case, it was present in the logo partition itself.
But in your case, it guess it's in the bootloader (it was not present in splash partition).

I've noticed that when I powere on phone It shows quickly splash, then warning about unlocked bootloader, after this splash again and at last bootanimation.
So where should I dig?

As i said, it's in the bootloader partition (maybe named 'aboot' or something; find it out yourself).
However, it's not recommended to modify the bootloader, since it might brick your device, even if it displaces by a single byte..
