I bought a used Megadrum. Not sure how to update it

[ddrummer68]

I purchased a Megadrum from a member of the VDRUMS forum, who had himself purchased it from another guy on the same forum. The firmware is 20100301, which I think, means
there's no encrypted bootloader. So, I must either accept the old firmware, or else purchase a Atmega chip and request that Dmitri load the encrypted bootloader. Is that correct?

This is a 32-input Megadrum, and other than that, I have no idea how to know what frequency crystal is installed, or what other information might be needed to choose the correct bootloader chip. But I would like to be able to update the Megadrum to the latest firmware. How may I do this?

I appreciate the help, even if it's just a helpful search term I should have used to get to the correct answers.

Thanks,
Bobby

The only way to be able to load latest firmware versions in your MegaDrum is to have it programmed with the protected bootloader by me. PM me if you're willing to pay the postage both ways and small handling fee.
