UEFI Logo Change

I'd like to know if and how it's possible to change the UEFI Logo on startup.
I've checked the ODROID tutorial, but it is about another the ODROID C2 ( ... e/bootlogo). I'm specifically interested in ODROID-H2.

I've found another post on this forum (viewtopic.php?f=168&t=35938), but it doesn't seems to me that there are any valid solution.
I've also tried with HackBGRT. Unluckily the UEFI executable it provide start slightly after the firmware has already shown the hardkernel logo hence showing the logo for a little bit before being replace with my custom image.

Any suggestion?

You missed this one: ... source=app
Hi mad_ady,
I've read that post (and actually it is quoted in my first post), unluckily it doesn't seems to have any valid solution.

To sum up what were the proposals in that thread:
-Manually patching the BIOS -> this create corrupted images
-Intel integrator toolkit -> this doesn't seems to work on this specific bios
-HackBGRT -> that's OK, but it shows the hardkernel logo for a while before replacing it with my custom logo

Let me clarify.
Our AMI BIOS license doesn't allow us to distribute a build tool to end customers.
So we can't help you.
Sorry about that.

Other SBC manufacturer seems to support it. But their service fee is quite expensive.

@odroid Couldn't you do it like you signed u-boot for xu4? Have the user supply the file (image) and you do the packing in a valid bios and offer just the bios for download?
Bonus points if it can be automated - just provide a url with photo upload which does the packing in the backend and spits a custom bios out. Though I don't expect there will be many requests...

Ok, I understand.

Actually I'm testing another Intel SBC that allow me to do these kind of customization without paying an additional license. That's a pity that I can't do the same on ODROID.

Anyway, thanks!
