"Control Board Password Error, Please replace the Control Board"
Cause
Error 27 occurs when rental vehicles are not properly STLinked or an incomplete firmware dump is used.
It can also be caused by using an old serial change method.
This error is the same across the Ninebot SNSC 1.0, SNSC 1.1, ES1, ES2, ES3, ES4, Ninebot G30/Max, G30P, G30D, G30E, and any other Ninebot G30 series scooter.
Fix
To temporarily fix error 27, hold down the brake and throttle on boot up and release once it beeps.
Changing the serial number twice using a newer dAuth supported serial change method.
Ninebot IAP, Ninebot-Flasher, and a ScooterHacking Utility all support this.
If that doesn't, flashing a CFW using cfw.max.sh with error suppression 1 or more enabled will also solve the problem.
