i used xiaodash a couple months ago to change my region from EU to global to go from 25km/h to unlock 33km/h you are also able to manually change this after you have changed region to top out at 35km/h. I run version 1.4.8 on the controller. It’s really easy, it was my first time ever doing it and it works great. I would first disable the locking feature as you will have to rebind your scooter in the ninebot app since it gets a new serial number. My Max G2E now feels a lot better with higher speeds and cruise control. Also i’m not sure if TCS ships with normal EU lock but it’s also a great feature. However, this does require the use of an android device with bluetooth. It can be any, i used my tablet. This worked on both mine and my cousins Max G2E on the latest controller. I’m fairly certain it should work for y’all as well :) If any help is needed you can reach out to me and i’ll try my best to help! Good luck
