For those out there that have expertise and experience in replacing Xiaomi/Ninebot controller boards:
So my scooter's controller board got fried when braking down a steep hill, and I just managed to replace it. However, some strange issues still remain: The motor works fine now. I can connect to it with the Mi Home app, and all the numbers in there looks good. Looks like its entirely functional.
However: the display always shows 0 km/h speed, and it only lets me choose between ECO and D. The battery indicator is just a single blinking red bar, even though the app says 80%.
When i try to flash a custom firmware, using M365_downG on Android, it will connect to the scooter, but when I tap "check ver" and "batt_info", nothing happens. It says its checking, and freezes there.
My research online says I have to activate the new controller, by changing its serial number (or something), and the manual included with the controller indicates the same (shitty chinese English).
How do I do this? The guide I found for the Ninebot scooters wont work on mine (the windows app freezes like on android).
Guide i mentioned:

Anyone with some knowledge that could help me out?
Update:
So I drove it for a few km, and its totally functional, besides the display showing 0 kmh and a red blinking battery. Because of the fact that the display thinks its low on battery, im unable to use Sport mode.
Update #2:
BMS firmware version is 1.2.6, and I was using custom firmwares before the board fried, so my last firmware build is still there.
