I received the dreaded 19kph update a while ago. I ordered a new display from china and decided that today was flashing day. I found this forum and the scooterhacking.org app.
Sadly if didn't go so well. I generated what I thought was a default firmware, flashed that. Now the scooter is unresponsive and when I try and flash the vanilla firmware I get "ERROR! Cannot read DRV version". This is somewhat stressing me.
My best guess is that I should have loaded the new firmware into the cache before flashing and I have flashed a blank firmware. Any help to get out of this mess is appreciated.
