SNSC 2.2 retired rental scooter question

Hey there! I bought a used Beam Solo scooter yesterday and it's a Segway/Ninebot SNSC 2.2. https://www.beamsolo.nz/products/buy-outright .. I asked Beam if there was a way to enable the smarts on it but they say they removed the IOT infrastructure inside and it can't even do Bluetooth anymore. I'ld like to be able to check its odometer and also ideally remove the 25km/h speed limit (if it's possible). It does have a B logo on the dash but obviously the interface is missing/disabled/something. I found this howto hosted on github https://github.com/timeylies/How-to-convert-a-Ninebot-SNSC-2.2-or-2.3-Scooter but it looks like a lot of work and I suspect as it's already been "converted" (ie the IOT stuff has been disabled) i might not be able to get anywhere with it anyway. Does anyone have any suggestions, please? Is there a part I could replace/add?
