Hi,
Updating this device (QY100) is a scary endeavour, if you've ever tried. I bricked mine while trying using the .MID file from JayB's site. but it was not the file, rather the tool. I ended up using the file on this forum. You'll mostly find that if you're on a Mac you will be directed to using Sysex Librarian as the tool of trade, to do this, but you will get errors during update this way.
I had a Firmware version 1.04 and tried with the sysex librarian and other tools, including some sequencers. But all gave me errors or checksum errors during the process. So if you're on a mac and trying to get this file to work right, please give a try to MidiKit: ?
Great little tool, honestly did the work flawlessly, which means this tool truly transmits sysex without modifying the message at all. Just set it to about 80bpm, and update, it'll take around 24 minutes, but it will update ok.
