The person who sent me this dump didn't tell me that he removed memory from the board for programming. It has no pinout to provide.
I'm trying to get a pinout but I haven't been able to at the moment.

The files I uploaded is not a backup made by me. This backup was given to me by a friend who had it in his database. This is a backup of a different model but with the same mainboard, so I assumed it was identical. But I'm not sure.
It may have additional files for settings or features that this model has and the other model did not.
You can try it, but if it's partitioned differently it's likely that it won't work or that it has functionality limitations.
You can also try adding the missing files to the same folder and recording them together. Honestly, I can't say exactly.
