The GSM-board seems to have what looks like a ST-link interface. Im still waiting for my adapter in the mail, so I cant do anything with it yet. But since I want to bypass the entire GSM-board I hooefully wont have to anyways.

Its accessible as soon as you remove the GSM-box, so I imagine that it is used to activate the scooter from the factory or similar.

I will post pictures of the GSM-board tomorrow, I forgot to take them today.
Any updates on this?
Did you STLink the board and extract the firmware? Surely that will be easier than u having to write your own firmwarez

I don't have the knowledge, to that, if it's just a normal st link flash I might be able to?

How do I get the battery out? There does not seem to be any opening wide enough for that.

I believe those have a rivet near the bottom that you would need to drill out or break away in order to separate the post from the frame and fork.
