Yes, Finally I have reverse engineered enough for a source release.

**** THIS IS NOT A REPLACEMENT FIRMWARE!! ****

Its not working in a long way. it needs _ALOT_ of work!

This firmware is designed for WG791 (Other models may be compatible with small changes)
The firmware can be put on a USB (as "DB275_GRAF.bin" ) and be flashed with the original bootloader. This firmware keeps the original bootloader so it is possible to restore original firmware.

This firmware does not brick my mower. But, It might brick yours!
I don't take any responsibility but I will help you try to fix it. It would REALLY be a good idea and backup the original firmware fist ( the firmware-file from worx does not include bootloader! )

The code Really needs a lot of work, it is just a proof of concept.

If you are brave enough to flash it, and want to try the motors out, please remove the cutting blades first.

After entering one of the menu's, press 'start' to initiate all settings, pwm, gpio etc.

keys as follows:

1: Start/Stop
2: Brake on/off
3: Forward / Reverse

Debug IO prints all IO, you should see changes if you close/opens the lid for example.

Please let me know if you want to help!
