Quote:It is the example of decoded files. .PNG is the original file. .PNG.ASTC is the re-saved file. .PNG.ASTC.PNG is the output file by `astcenc` tool from github.

Also, from your screenshot, you XOR the whole file instead just the 16 bytes header.
Good luck!

Sorry, but that wasn't very helpful. I saw the example. I still don't know what went wrong. That hex editor I used seems like it doesn't account for editing a single line of 16 bytes. The other hex editors I have are HxD (doesn't have an XOR function), Hex Editor Neo (doesn't support saving files under different formats properly) and Hiew32 Demo Version (I don't know my way around it.)
What hex editor did you personally use? Honestly a video tutorial for this sort of thing helps for those of us who aren't programmers.
