This bin file will replace the "Bootloader unlocked" warning message with stock splash screens.
To use:

1: open adb CMD
2: type 'adb reboot bootloader'
3: type 'Fastboot flash logo logo_fix_*****.bin'
NOTE:::::: Replace ***** with White or Black as appropriate for your chosen logo download.
4: Restart and enjoy

Yes, this mod is cosmetic. It won't magically lock your bootloader. That warning is hard coded. These bin files are too just mock the locked state for those who are annoyed by it

ya i know it wont re-lock it :) this actually does remove the warning, i stand corrected. flashing the logo.bin from the retail zip in the other thread only took away the t-mobile logo splash...

THANKS! That warning screen has always annoyed me I flashed the black one. I love it. Looks "Oldskool" Like my Droid X back in the day :D

Can't we just push this to system files and grant proper permissions or does it have to be flashed?

Well... If TWRP can access /dev/block/bootdevice/by-name/logo_b(a) then someone can make a flash able zip quite easily.

I remember on all my HTC phones TWRP could flash to that partition when s-off to remove their Dev splash warning and on some others it required to manually flash a hex edited bootloader, so it just depends
