Thanks to the tireless work of the team at ScooterHacking, ScooterHacking ReFlasher has now been updated to v1.4 and supports downgrading the Ninebot Max G2 DRV/ESC!
I bought a controller months ago in anticipation of this so a full guide will be coming soon.
For now, follow the pinout linked in the app.
