PCB Photos

Will take a pic of the rest of the PCB if needed, but I'll have to disassemble it again hahaha.

@jja2000 thanks for the report!

Stock Firmware MD5: Not sure, is the full one below enough?

You can get this MD5, by not supplying any additional parameters (-b or --full) to the read operation command. I'm also surprised that the bootloader MD5 is one that hasn't been seen until now. Could you share the hex files you got? (main firmware and bootloader, or a full read)

Hi there!

@jja2000 thanks for the report!

I will update OP, thanks!

I'm also surprised that the bootloader MD5 is one that hasn't been seen until now. Could you share the hex files you got? (main firmware and bootloader, or a full read)

Will add those to OP aswell, this is how I got the keyboard out of the box. I did not update the firmware using their driver program.

Just to add, I'm planning to contribute to SMK if you think that's feasible. But I'd love to make sure that everything is at it's supposed to be before I start porting (considering the brick risk you mention in your blog).
