Problems with back side and unlocking the scooters speed
So after like 7 days of owning the scooter the 25kmh has gotten really boring and i need it go faster like 35-40kmh and im from europe and thats the problem i cant. Ive tried using SHU but its restricted something about the firmware idk how to unlock it SAFELY without the scooter getting cooked. I wanna flash the older versions of BLE and VCU and other stuff but idk how safe that is and if it will even let me change the region after that. and also whenever i step on the scooter on the back side, like the middle of the deck it starts like squeaking. that happend i was on a dirt road with a lot of rocks and i stepped on a big rock (100kg on the scooter) and the rock cracked under the front tire and the back side started squeaking. So to get rid of the noise i watch the back spring and the wholeback side and it stops squeaking for like a few hours. Yea but mostly i need help on the unlocking of the scooter, any help will be useful!!!
