I've a MacBook
Okay, here's 2 logo.bin replacements, one is flashable in TWRP (ending in .zip) whereas the .bin file requires flashing via fastboot. They are compressed into 1 zip for upload to XDA, so please decompress the zip before use (you should see both the .bin and .zip as a result).
These logo.bin are based off the logo.bin from the NPJS25.93-14-18 firmware (April 2018 security patch). I have replaced the logo_boot, logo_unlocked and the orange unlocked bootloader warning. I have not replaced the yellow 'different OS has been loaded' warning or the red 'your device has failed verification' warning deliberately, to assist in troubleshooting.
I've already hidden my bootloader warning.
I wanted to use my designed bootloader
I'm not sure what you're after - the zipped custom logo.bin above are designed to hide the bootloader warning with your custom designed bootloader logo. You cannot alter the bootloader, but these mask the warning. As mentioned above, I've applied your custom design to the logo_boot, logo_unlocked and orange warning logos. On boot after flashing, you should see your custom bootloader logo.
Daaamn, I should've reserved the 2nd post but okay

--> Added Ironman bootlogos (Original, Minimal)
Anyone can do that.., extract logo.bin from the zip, load it in MotoBootLogoMaker application, select 'logo boot' and click on extract to save that image. I have attached it here (add plus symbol yourself and post it here )Bro ,what I meant is that these two bootlogos only contain moto g4 text but mine is g4+ so I asked the creator that he is willing to add +sign after g4
