Unlocking Bafang m400. Is it possible?

[adam-ht]

Hi, I recently bought KROSS trans hybrid 2.0 and I need to say it's great, but the speed limit is a little low for me (25km/h), so I want to enhance it maybe to around 30-35km/h. Is it possible? I read that it isn't possible in any factory built e-bike(I don't know if it's true), I have already tried using esp32 with a canbus transceiver to sniff the canbus,but when I turned the display on it showed me error 30 which means that there is no communication between display and controller.
The display is dp C11.CAN and the motor is MM G330.250.C 15
Thanks in advance
