So I got C2 off cleanly. I connected the 3 wires as instructed - mind you mine is beeping with error 32 which I'm still trying to figure out means this can still be done - and I get this error:

Cany anyone help?

Its saying can't connect to target check your soldering and make sure you're connected to the correct wires. Pull the cover off your STLink and make sure the wires match up sometimes the label on the cover is wrong.

Yes Rex, the error doesn’t mean much for flashing other than that the scooter is irritating. It can still be flashed.

Hello 👋
I have never flashed a max spin scooter Before .
So I am very new, I joined the community too see the difficulty of flashing is an tbh I’m still confused. Idk where to download the files an I don’t know what computer can download them I have Mac book air running OSX El Capitan an I do have a windows 7 desktop computer
What machine you recommend I use to download the files to run the flash ?

An one other question I have a wire that I made that can connect straight to the Iot cord that Lies behind the Iot an it fits but do I still need to any soldering to the dashboard?

One end of the cord is Usb an the other end connects to the cord the Iot connects too.



If some one can help me with this that would be great an I can send you a picture of the cord I have an you can tell me if it will work.

Thank you once again .

Just wanted to add some experience here. I just did this with an M365 Pro dash as well as a Ninebot Max dash from aliexpress and it worked on both. I will be posting a comprehensive tutorial on how to get one of these scooters working including BMS flash, dash flash, ESC flash, and using Ninebot Flasher to get things working with a custom firmware.

Sucks error code 19.
I flashed the BMS first, then the controller, then the dashboard. I also re-wired the harness back to OEM. On a bad flash of the dashboard, I got an error 19 and even after reflashing the dash, it didn't go away. I ended up reflashing the controller as well - then all was well.
