The HC1 prefixes of your sample images do not result in the same image as the corresponding sample images and can not be read by decodeqr.

Sorry, I didn't specify that I am not the author of the qrdecode part, try opening an issue here:

Test data are instead taken from here:

Anyway you are right, createqr.html creats an invalid QR code for any QR reader:

Weird thing is that the recreated valid QR code is completely different, and simpler, than the original, but it contains exactly same data.
