Exchange png logo in BIOS flash update file -- 2

Job ID: 34620519

Budget: $10 – $25 USD

Hello!

This job is only for really special people who enjoy doing almost impossible things and who want to have a great rating.

I have a BIOS flash update for a custom motherboard. The company who originally manufactured it does not do any updates for it.

The BIOS flash update has a custom boot logo embedded.

I would very much like to exchange it with a new / different logo.

I have read that one needs to decompose the file, replace the image, recalculate the checksum and be very very careful in order not to do any errors, but I have never done this myself.

Please only bid if this is fun for you because I can not pay more than 25 € for this take.
If nobody wants to do it, I will just keep the old logo.

But if somebody can do it, I would be very pleased and excited.

Thank you if this interests you! :-)

Please ask me anything, I will try to answer your questions.
