Where to find default firmware for WIO terminal

Recently I’ve been replace my WIO terminal’s firmware with ArduPy but It’s don’t have much document for them. but now I want to rollback my firmware to default and I don’t known where to download them please help.
thanks in advanced.

If you get into Bootloader-Mode (fastly reset twice, as shown here) you could copy over any UF2-File of your like.

I didn’t have old (default) uf-2 file can you upload it for me please?

The original UF2-File it came with was the Jump-Game.
You could compile it from its github repo with Arduino IDE

For convenience I’ve uploaded my version here(vald for 12 hours)
